OK the countdown begins

9 days and 16 hours until official release of scores

By Shizpit (Shizpit) on Tuesday, June 08, 2004 - 04:19 pm: Edit |

don't they release the scores like in the afternoon the day before they actually say like 4 p.m. on the 17th instead of the 18th or at least thats what i heard is it true?

By Dannyferizzle (Dannyferizzle) on Tuesday, June 08, 2004 - 04:43 pm: Edit |

yes-it should be 8 days and 16 hours

By Hollaratme (Hollaratme) on Tuesday, June 08, 2004 - 04:44 pm: Edit |

yeah thats true and usually they release the format of the tests on the weds after the test but this time they actually released it ydaay (monday) so im expecting the scores to come earlier like maybe weds

By Monoe (Monoe) on Tuesday, June 08, 2004 - 05:03 pm: Edit |

notice I said OFFICIAL RELEASE

By Delacroix (Delacroix) on Tuesday, June 08, 2004 - 07:37 pm: Edit |

I guess I had the form:

math (regular 5-choice questions)

verbal (2 reading passages)

math (QC and SPR questions)

equating (the one that doesn't count toward your score)

verbal (3 short passages and 1 long passage)

math (regular 5-choice questions)

verbal (long reading passage)

I think. The equating was verbal, so this should be right. However, then the equating section is not what I thought it was...I thought it would be section 5, but it is instead section 4. Did any of you get this form? Can you jog my memory on the types of questions on the verbal equating section? This could be bad...

collegeboard should have an option where you can predict your scores. if your predicted score = actual score, then you should get a prize :-]. it'll give us losers something to do than to be clicking refresh all day.

you guys are so US-centric.

if i see another person explain the "fluke" where the scores come out a day early, i will break something and throw it at something until i regain my ability to articulate myself in english.

the nutty reason the scores come out a day early: they have to be available on time for those of us in asia.

By Mercury (Mercury) on Sunday, June 13, 2004 - 11:49 am: Edit |

I have another valid idea--with everybody trying to get their scores at the exact same time, they release them early to alleviate some concerns (similar to a likely letter), but most importantly, prevent the servers from crashing under such tremendous load.

By Titanz05 (Titanz05) on Sunday, June 13, 2004 - 05:55 pm: Edit |

If your asian, why is your screen name 'macandcheese'. Sorry I'm just wondering. That's like it being "Applepie45" or something.

I think I botched up writing and i definitely messed up us history (i almost started laughing halfway though it on account of how much i forgot in a month since the ap test), but i'm really looking forward to my spanish score... i'm thinking i got all of them right, which means i probably got around 5 wrong, i'm hoping for 750+, maybe even an 800 ( i would be ecstatic). Monday, Tuesday, Wednesday, and .5Thursday left!

what time exactly, 4 pm, 4 pm what time zone?

By Billiam2 (Billiam2) on Monday, June 14, 2004 - 12:15 am: Edit |

probablly EST. Everything is EST (in the U.S at least), i don't know why though.

By Altf4 (Altf4) on Monday, June 14, 2004 - 12:21 am: Edit |

so which one is it? 2, 3, or 4 pm? (EST)

probably because collegeboard/ETS is on the east coast

what hour did it come out last time?

By Astrix (Astrix) on Monday, June 14, 2004 - 05:04 am: Edit |

Nopes Macandcheese, I don't think the reason they come out with the scores earlier is for us internationals.

They mention 18th May, 8am EST on the site. Lightening the load on the server is a more plausible explanation really.

And no, I have nothing better to do.

For Biology i think i got an 800. from the biology discussion, i havent missed any yet. for math IIC i am trippin' out right now. it was not a hard test and i could have done everything on there.........if given the time. i simply didnt have enough time. i omitted about 8 and i know i missed 3-4 (which means i probably omitted more and missed more too) lol, i am HOPING for a 700+. that would be really nice.

By Insanity (Insanity) on Monday, June 14, 2004 - 06:19 pm: Edit |

well, I answered one and then went back and erased because I was trying to decide between two answers. Maybe it will pick up the one I erased and it will be right. lol *wishful thinking*

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 06:32 pm: Edit |

Your scores should be available after 4 P.M. (EST) because our main headquarters are located in New York City. Make sure that you registered online at www.collegeboard.com.

If the average (arithmetic mean) of x, 5x-4, 2x-6, and 3x-11 is 25, what is the value of the median of these numbers?

By Athlonmj (Athlonmj) on Monday, June 14, 2004 - 06:55 pm: Edit |

Easy. the 4 numbers are 11,16,22,51 so median would be 19.

By Insanity (Insanity) on Monday, June 14, 2004 - 06:55 pm: Edit |

uh, is it 19?

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 06:56 pm: Edit |

Find the sum of all positive 3-digit numbers whose last digit is 3.

By Adidasty (Adidasty) on Monday, June 14, 2004 - 06:57 pm: Edit |

The numbers are 11,16,22, and 51. so uh.......the median is somewhere where i cant find it. lol

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 06:57 pm: Edit |

The answer to the previous problem is 19.

yeah 19 i guess. lol, makes sense

By Vtoodler (Vtoodler) on Monday, June 14, 2004 - 06:59 pm: Edit |

I think that he is an ETS rep. So Etsrep, when do you predict that Missouri scores will be up??

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 06:59 pm: Edit |

The median of 11, 16, 22, and 51 is the average of the middle two numbers since there are an even amount of integers. (16+22)/2 = 38/2 = 19.

By Adidasty (Adidasty) on Monday, June 14, 2004 - 07:01 pm: Edit |

Yeah when will mizzou scores go up?

By Adidasty (Adidasty) on Monday, June 14, 2004 - 07:06 pm: Edit |

What about Cali scores?

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 07:09 pm: Edit |

Missouri has seen a 26 point increase over a 10-year period in the mean SAT I verbal score. They have seen a 33 point increase during the same time interval in the mean SAT I math score. Missouri scores have gone up, if that answers your question.

Hey, ETSrep. Can you comment on how well the machines handle eraser marks? I know at my school if there are any marks whatsoever the machine will read it wrong.

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 07:20 pm: Edit |

If the eraser mark is not completely erased, the machine will pick up the eraser marks, even if you think you erased it thoroughly. The machine is naturally sensitive to graphite.

By Altf4 (Altf4) on Monday, June 14, 2004 - 07:32 pm: Edit |

actually, i think they meant to ask "when will Missouri scores be online to view?", and for that, i think it will be sometime in the afternoon of this thursday, although i still don't know what hour. obviously if ur east coast, u can expect it to be online in the later half of the afternoon, while if u live on the west coast, it will come sometime after lunch.

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 07:35 pm: Edit |

That is correct - the scores will be posted online after 4 PM Eastern Standard Time, which means that if you live on the West Coast, you can expect your scores after 1 PM.

By Thunder77 (Thunder77) on Monday, June 14, 2004 - 07:45 pm: Edit |

Hey..

When I erase, there is still a hint of darkness left behind on the answer sheet. Is that okay? Its like, I erased it really thoroughly, but you can still tell that it has been written on before.

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 07:48 pm: Edit |

Please do not be overly concerned about erasure marks. A hand-scoring service is available if you are concerned about erasure marks.

By Zbjz15 (Zbjz15) on Monday, June 14, 2004 - 07:53 pm: Edit |

Ok, thanks. One more question for you ETSrep. I assume you are familiar with the lost tests from Ardsley that were found on friday. Will they be scored on time and put online at the same time as all the other SATs?

By Hertish (Hertish) on Monday, June 14, 2004 - 07:54 pm: Edit |

ETSrep,

I took three SAT II tests instead of 2 SAT II's i registered for. WHen do the tests change in my SAT Status page in collegeboard.com? mine didn't change yet

By Hertish (Hertish) on Monday, June 14, 2004 - 07:55 pm: Edit |

ETSrep,

Also, when and how do i pay for the 3rd SAT II which i took but did not register for beforehand?

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 07:57 pm: Edit |

The lost tests from Ardsley will have their scores posted online by 6/17/04 after 4 PM (EST).

The changes to your SAT II testing should have been reflected in your SAT status page. If it is not, then the changes should appear when you receive your scores.

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 08:01 pm: Edit |

How did you manage to take the third SAT II without paying for it beforehand?

By Hertish (Hertish) on Monday, June 14, 2004 - 08:06 pm: Edit |

I just added it on the test day..

I called collegeboard like 2 weeks before the test and the lady said that i was allowed to add a test on the test day

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 08:12 pm: Edit |

Contact College Board for more information about paying for the additional SAT II test.

ETS rep let's say a test taker misaligns a section on the SAT, will anything be done or will the score stand?

i'm sure this has happened before?

By Etsrep78328 (Etsrep78328) on Monday, June 14, 2004 - 08:28 pm: Edit |

Generally speaking, since the SATs are machine scored, the score stands as is, even if a section is misaligned.

Oh, yea. ^^^^That is a great question!!! I doubt he would be allowed to though. If by some miracle Etsrep can answer SAT questions I will give my disputed 3.

1. Sentence completion with 1890s doctors. It was the first one.

2. What is the meaning of "stepson" in the da vinci passage?

3. What does the term whiff mean in the bronx passage?

I am not authorized to disclose any information regarding the content of the verbal and math sections on the June SAT, since we may "recycle" those questions.

For those of you who are anxiously awaiting your scores -- please be patient and wait until 6/17. I am not responsible for posting the scores online -- if I was, I would have posted them up sooner as I am aware of the fact that you can't deal with the agony of waiting to receive your scores.

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 02:05 pm: Edit |

By the way, here is a grid-in math question that MIGHT appear on the new 2005 SAT. If you think you have the correct answer(s), please post it. Thank you.

There are two different real values of C for which the equation Cx^2 + (3C+6)x + 5C - 40 = 0 has equal roots. Find one possible value of C.

ETS rep - If a student took the SAT II writing but made the mistake of putting their initials in the box at the bottom of the second essay page, when, in fact it should have been the first two letters of their surname, will their essay still be identified correctly? Will this mistake affect the score, will the student still get the right score? How does ETS handle such cases...there are quite a few people who made this mistake.

For equal roots, D = 0

=> (3C+6)^2 - 4(C)(5C-40) = 0

=> 9C^2 + 36 + 36C - 20C^2 + 160C = 0

=> -11C^2 + 196C + 36 = 0

=> 11C^2 - 196C - 36 = 0

=> 11C^2 - 198C - 2C - 36 = 0

=> 11C(C-18) - 2(C-18) = 0

=> (11C-2)(C-18) = 0

=> C = 18, 2/11

Good job Astrix -- except that you made a computational error when factoring by grouping. It should have been 11C(C-18) + 2(C-18) = 0

(11C+2)(C-18)=0. C = -2/11 or 18.

Here is a final math question for those of you who are good at probability: Emily selects a number at random from the set {1,2,3,4,5} ten times (independently). The probability that she will choose an odd number at most three times can be written in the form (c x 2^n)/(5^m) where n and m are positive integers and c is a positive odd integer not divisible by 5. Find the value of n + m + c.

The June SAT IIC was considerably more difficult because I made up the whole test (just kidding). We decided to make the SAT IIC harder because more students are taking advanced math courses in the secondary high school education. We saw the need to make students think more creatively when it comes to applying algebraic and trigonometric reasoning.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 03:57 pm: Edit |

independent means she doesn't remove the number that she has selected, so the probability of a certain event happening would stay the same as many times as there are trials.

there are 3 odd numbers out of 5 total numbers, the prob that she will pick an odd is 3/5, if she picks them 3 times (in a row?) then it will be 3/5 x 3/5 x 3/5. it's multiplication because in adding, you are expecting to increase the chances of two separate events, like choosing both the odds and the evens at two selections.

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 04:10 pm: Edit |

The answer to this problem is quite complicated -- it requires the use of the binomial probability theorem. There is the probability that Emily could pick three odd numbers OR two odd numbers OR one odd number OR zero odd numbers. [10C3 * (3/5)^3 * (2/5)^7] + [10C2 * (3/5)^2 * (2/5)^8] + [10C1 * (3/5)^1 * (2/5)^9] + [10C0 * (3/5)^0 * (2/5)^10] = [(2^8)/(5^10)] * 2089.

n = 8, m = 10, c = 2089

n + m + c = 2107.

Thanks ETSRep!

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 04:37 pm: Edit |

rough and lenient are in relation to previous curves

a rougher math for the SAT I would mean that it would take a higher raw score to get the same scaled score as before.

a more lenient verbal would mean even with a lower raw score (2-3 points), you could still earn the same scaled score.

understand?

ummm that question's unsolvable. i hope "cannot be determined is one of the answer choices". I didn't take SAT II math, so i'm not sure...

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:31 pm: Edit |

that's what i was thinking, since it's not a line or anything

i mean, unless we used some form of calculus, i'm guessing? but then we would need the formula to calculate the derivative.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:36 pm: Edit |

i have an idea. the parabola is obviously shifted to the right (relative to a regular parabola with the vertex on the origin). now imagine a line going through the two points. though on a regular parabola (on the origin) this line should be a flat line with slope 0, in this case it's a line slanted a little down on the right side (negative slope). perhaps the slope or the angle which this imaginary line makes with the horizontal is some sort of "deviation factor" with which the parabola deviates from the origin...

in my opinion though, asfafam may be right.

By Monoe (Monoe) on Tuesday, June 15, 2004 - 06:38 pm: Edit |

No, it's answerable because the x-coordinates are opposites. Obviously it begins y = x(squared)...but then what?

First, realize that it must be x(squared) *minus* something. Why? Because the x value -2 gives you a larger number than does the x value 2.

Next, play with the "bx + c" part, using only numbers for 'b' and 'c' that would make (-2, 45) and (2, 13) on the graph. The only combination is -9 and 27

y = x(squared) -9x + 27

f(1) = 19

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:39 pm: Edit |

i think it's unsolvable. the parabola can actually be stretched up and down without any effect on the two points. imagine a parabola going through those points - now stretch the vertex up and down - no effect. i think it can vary, so i'll say no solution.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:40 pm: Edit |

i don't think there's any calculus involved...it's either a simple principle i haven't learned, or there's no answer.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:41 pm: Edit |

monoe - i think it's unsolvable. you can draw any parabola through the two points - they can be on the same or opposite sides of the vertex. along with my previous post, i think it is unsolvable.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:43 pm: Edit |

what i mean is, the parabola could be this giant ass thing - an upside down one - with the two points on the same side of the vertex.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:43 pm: Edit |

monoe- how did u come up with the -9 and 27, i just don't see it

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:45 pm: Edit |

i agree with haruhara, i heard somewhere, maybe in my math book, that one would need 4 points to define a parabola, but i could be wrong

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 06:45 pm: Edit |

In order to solve this problem, you need to put the equation of a parabola in terms of (x-h)^2 + k, where the vertex is at (h,k). Thus, two equations can be set up:

(-2-h)^2 + k = 45

(2-h)^2 + k = 13

4 + 4h + h^2 + k = 45

- 4 - 4h + h^2 + k = 13

=======================

0 + 8h + 0 + 0 = 32

8h = 32, h=4

(2-4)^2 + k = 13, k=9

f(x) = (x-4)^2 + 9

f(1) = (1-4)^2 + 9 = (-3)^2 + 9 = 18.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:48 pm: Edit |

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:49 pm: Edit |

etsrep, what about the absolute slope of the function? you know, the coefficient behind the term (x-h)^2?

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:49 pm: Edit |

really?, but i see that there are 2 variable 2 equations, why doesn't it work?

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:50 pm: Edit |

u mean the coefficient in front of the term?

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 06:51 pm: Edit |

If there was a coefficient behind the term, this problem would not work out with a system of equations. In a problem like this, normally it would be specified that the coefficient is 1.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:51 pm: Edit |

why can't we contort various parabolas and fit them onto these two points? i see 3 possible parabolas that can fit onto these points already.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 06:52 pm: Edit |

oh well in that case, only 1 of the three works. but i assumed it can be any parabola.

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 06:53 pm: Edit |

Did you find another equation for this parabola where the coefficient A = 1 in the form Ax^2 + Bx + C?

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:55 pm: Edit |

4 + 4h + h^2 + k = 45

- 4 - 4h + h^2 + k = 13

=======================

0 + 8h + 0 + 0 = 32

should there be a negative in front of the 4 in line 2? from what it looks like, u took the system and subtracted right?

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 06:56 pm: Edit |

I want an honest opinion from everyone: Should a parabola question that involved be included on the new SAT? The coefficient would be specified, by the way.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:56 pm: Edit |

if the coefficient is set at positive one, then there's only one possible orientation, because the other variables are controlled.

EtS, are you making these up or what source are you getting these questions from, i'd like to find more practice.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 06:58 pm: Edit |

i believe that that question is manageable with the coefficient of 1, of course, it would be one of the harder questions on the test right, since new material will make up only a small portion of the new test.

By Etsrep78328 (Etsrep78328) on Tuesday, June 15, 2004 - 06:58 pm: Edit |

I am making these questions up based on previous discussions I have had with department chairs and supervisors of math who suggested that these are good questions for the new SAT.

so there is no other parabola that may be able to pass through these points? assume that the vertex can be anywhere and that the parabola can be stretched around (while maintaining even-ness)

4 - (-4)=0?? [system of eq, in the solution u provided]

By Athlonmj (Athlonmj) on Tuesday, June 15, 2004 - 07:01 pm: Edit |

I think the parabola question should be fine... I mean the ACT even had matrices and a geometrical proof (albeit they were not very hard).

By Mr_Sanguine (Mr_Sanguine) on Tuesday, June 15, 2004 - 07:02 pm: Edit |

it seems fine for those that are at/near the end of the math section

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:02 pm: Edit |

haruhara, assuming that it's pointed up or down instead of right or left, yes.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:03 pm: Edit |

well i started the problem with:

45 = j*(-2-o)^2 + p

13 = j*(2-o)^2 + p

and then equated them (by pulling the 13 and 45 to other side to equate to 0), and realized that there are multiple possibilities for the parabola because of the term j

j = absolute slope

o = right shift

p = "up" shift

The system of equations is a little lopsided there because of the way it was formatted to fit the screen -- but it works out 4 - (-4) = 8.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:05 pm: Edit |

altf4, what if the parabola were upside down, shifted left, and up? the "right side" of this new parabola may (probably does) contain the two points with enough manipulation.

By Theleet (Theleet) on Tuesday, June 15, 2004 - 07:05 pm: Edit |

cmon people get a grip. First this person claims to work for ETS posting questions that might be on the new SAT. Theres no way in hell that an ETS member would ever do that. Second, this person is asking our opinion of a question that is a "possible" question for the SAT. When has ETS ever cared about what we thought about the test? Finally, if I was an ETS worker I sure as hell wouldn't want to work after hours. You people are delusional.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:07 pm: Edit |

if 4-(-4)=8, then why is there a 0 in place of the 8

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:08 pm: Edit |

theleet has a point there, but still i like these questions

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:08 pm: Edit |

what if we reflected the parabola about the line

y=x/8 + 29 (it's the line equidistant from either points)? i think it would be the mirror image of the original, upsidedown, and containing the points.

By Athlonmj (Athlonmj) on Tuesday, June 15, 2004 - 07:08 pm: Edit |

Theleet,

honestly who cares if he's an ETS rep or not. We're all waiting here for our scores and this guy comes along and makes the thread interesting. Even if he is not, might as well play along. Ignorance is bliss

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:10 pm: Edit |

haru, that's a good point, may i ask how u came up with the line?

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:12 pm: Edit |

this is what i did:

i drew the points. got the mid point. got the slope of an imaginary line between the two points. got another line perpendicular to those points. the line going through the originals happens to have a slope of -8, so the new equidistant line should have a slope of 1/8. so

y= x/8 + b

it travels through the midpoint. midpoint is (0,29). plug in. get b.

y = x/8 + 29

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:14 pm: Edit |

basically just got the change in height and change in x and got the slope that way. mid point is just 1/2 the change in height (or the average of the two y values and two x values) and 1/2 the change in x.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:15 pm: Edit |

thanks haru, but the midpoint just happened to be the y-intercept?

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:15 pm: Edit |

i know how to calculate midpoint, but i'm just losing everything i learned at such a rapid pace.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:15 pm: Edit |

well duh, it has to be. the x values are -2 and 2. what's in between them? 0

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:17 pm: Edit |

haru, then if it were reflected over that line that you indicated, the parabola would be upside down, therefore yielding an upside down or sideways parabola

since the ETS "claims" it will provide the coefficient of 1, it would also have to provide whether this equation is y= or x= oriented.

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:18 pm: Edit |

yo udon't really need to "calculate" it... really it's annoying when i hear people ask "WHAT"S THE DISTANCE FORMULA" or "WHAT'S THE MIDPOINT FORMULA"? just use the pythagorean theorem for finding distance (which is all the distance formula is) and consider y and x components of vectors for midpoints.

PS: i'm NOT saying this is you. i'm just giving an example.

PPS: the "duh" was not meant to be offensive.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:19 pm: Edit |

i still don't get the system of equations, why isn't the end result 8+8h=32, if the two equations were subtracted from one another?

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:20 pm: Edit |

ah that's true. it wouldn't be a true parabola. perhaps not even a function.

but trust me, there are other parabolas that can fit these points.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:20 pm: Edit |

wow vectors, i believe i failed that chapter on vectors and parametric in pre calculus this year

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:21 pm: Edit |

they weren't subtracted. they were added. i think...

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:23 pm: Edit |

it would still be a parabola if the line was vertical or horizontal, but with a slope of 1/8, it's a slant, and that would yield the functions which have a change in axis (not perfectly straight, but tilted). i don't think the new SAT will cover that.

By Zbjz15 (Zbjz15) on Tuesday, June 15, 2004 - 07:23 pm: Edit |

Yea, I really think a mod should do a IP check to see if it matches up to another user. This whole thing is fishy. I would think the new SAT difficulty would be finalized by now and the ETS wouldn't be asking some people on a messageboard what the difficulty should be.

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:23 pm: Edit |

they can't be added, look at the equation again

By Altf4 (Altf4) on Tuesday, June 15, 2004 - 07:27 pm: Edit |

oh i know, he didn't respond to my question about the collegeboard books, it's somewhere up there...let me ask it again.

"what other books are being published by the college board and ETS besides 10 reals for the new test?"

u c, if he answered that, it wouldn't seem fishy because he's an employee, and obviously wants to advertise their products, but he didnt. which is the thing.

what does everyone else think?

By Haruhara (Haruhara) on Tuesday, June 15, 2004 - 07:29 pm: Edit |

exactly. but the line should have been horizontal to produce a new parabola. any line with an absolute value of the slope being > 0 will yield a non-function of a parabola.

I just got back from a conference and I am exhausted. However, I figured that I would inform you of the new products that are coming out (in the fall of 2004) for the new SAT before I go to bed.

There will be:

1. A new 10 Real SATs book which will reflect the material covered on the 2005 SAT

2. An SAT Teacher's guide with lesson plans, handouts, and exercises

3. An online course including three practice tests

4. Various writing workshop programs for teachers to help their students prepare for the writing section of the exam

5. Updated SAT question of the day to reflect the new SAT material

Those are some things to look forward to, especially if you are taking the new PSAT/NMSQT in the fall of 2004 or the new SAT in 2005.

Do you reccomend that we sophmores take both the Old SAT and the New SAT, or just the new one?

And all the geeks who ask whether he is real or not, shut up. You're pissing me off with your stupid speculations and IP check crap, who cares? This guy here is knowledgable to say the least, and he is not gaining anything from helping us.

If he is real then that should be easy enough to verify from a mod. Also. to your question about if it would be fun. I am sure it is to string all of you along and have your word accepted as gospel from people like you.

Don's mood varies directly as the weather and as his social life, and inversely as the square root of his commuting time (in hours). If Don's mood rating was 36 on a day when the weather was quite good (rating 4), his social life was really good (rating 5) and it took him one hour to commute, find his mood rating on a day when the weather was very good (rating 5), his social life was rather poor (rating 2) and it took him only 15 minutes to commute.

By Astrix (Astrix) on Wednesday, June 16, 2004 - 09:00 am: Edit |

It'll still be 36

By Astrix (Astrix) on Wednesday, June 16, 2004 - 09:05 am: Edit |

hehe... the equation is

M = K (WS/T)

where M is Don's Mood rating, W is the weather rating, S is his social life rating, and T is _the underoot of_ his commuting time. K is the constt. of proprtionality.

So K = 36/20 (putting the initital values)

M = (36/20)* (5) * (2) / (1/2)

M = 36

Okay it's obvious that ETSrep is not real. There is no way in the world that anyone working for ETS would possibly go to a message board (the same message board that was monitored after the APs) to dish out the new test's biggest secrets. Sure it may be fun, sure it may be something that passes time as your OCD leaves you constantly checking collegeboard.com, but I just want to make sure that everyone knows this guy is a hoax. I pity the fool who thinks otherwise.

By Crypto86 (Crypto86) on Wednesday, June 16, 2004 - 11:03 am: Edit |

What happened to this being a countdown page! But, since ETS Rep is discussing specific IIC questions (I believe he is the real deal, but if not, at least it passes the time), I'll offer some questions for the physics sat ii:

The asteroid problem - greatest length. I said it would be on the spacesip traveling at 0.8c

(Distance = DistOrig/sqrt(1-v^2/c^2))

The largest number of v (which was .8c) will yield the smallest denominator, thus yielding the largest distance.

For the eV one I had 1.2 X 10^2 eV. It gave you the wavelength of the particle, and since it was of the electromagnetic spectrum its velocity is 3.0 X 10^8 m/s. You can get frequency (I think it was 3.2 X 10^15) and multiply that by the specific "h" of that problem (It was 4.12 X 10^-14). The exponents go to 1 and 3 times 4 is 12, thus having the answer at 1.2 X 10^2 eV.

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 11:25 am: Edit |

Good job Astrix -- the answer is 36.

In regards to your question about the analogy, it is AQUATIC:FISH::AMPHIBIOUS:FROG

A fish is an aquatic creater, just like a frog is an amphibious creature because it can operate on land and in water.

By Haruhara (Haruhara) on Wednesday, June 16, 2004 - 11:31 am: Edit |

dude, contraction = (absolute length)*(1 - sqrt(1-v^2/c^2)). or in other words, new length = (absolute length) * sqrt(1-v^2/c^2). it's an easy equation to derive using simple geometry and trig

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 11:41 am: Edit |

There will not be any trigonometry on the new SAT, but there will be a lot of the following questions:

1. Sequences involving exponential growth (E.g. 3, 9, 27, 81 ...)

2. Absolute value

3. Venn Diagrams - union, intersection, elements

4. Rational equations and inequalities

5. Integer and Rational exponents

6. Radical equations

7. Direct and inverse variation

8. Function notation

9. Domain and range

10. Linear and quadratic functions

11. Statistics and probability

An equation is of the form x^4 + rx^3 + sx^2 + tx + u = 0, where r, s, t and u are integers. Two roots of this equation are x = -5 and x = 1. The sum of the roots of this equation is -3 and the product of the roots of this equation is 30. Given that all four roots of this equation are integers, find the sum of the squares of the four roots of the equation.

ETSRep, I was reading the posts and I saw you say that there was a conscious decision to make the Math IIC harder this June.

Correct Astrix -- the answer is 39.

Here is a question that should be a challenge:

Let N1 be a positive two-digit integer. Subtract 1 from N1 and divide the result by 3 to obtain T1; let N2 = 2T1. Subtract 1 from N2 and divide the result by 3 to obtain T2; let N3 = 2T2. Finally, subtract 1 from N3 and divide the result by 3 to obtain T3; let N4 = 2T3. Find the smallest positive (two-digit) integer N1 such that T1, N2, T2, N3, T3, N4 are all integers.

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 12:56 pm: Edit |

The N1 has nothing to do with the tens or ones place. It just designates different variables -- instead of a, b, c, d, e, etc. there is N1, N2, T2, T3, etc.

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 12:58 pm: Edit |

so 2T1 would equal 2 x (value of T1) correct?

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 12:59 pm: Edit |

That is correct.

Approximately how many math could one miss to get a 700?

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 01:04 pm: Edit |

You are probably wishing that I said that you could miss 60 questions and still get a 700.

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 01:10 pm: Edit |

I'm just kidding Gumby -- read my previous posts about curves for the SAT.

I see the question about N1 is stumping you -- I am thoroughly satisfied. If you think you have the answer, let me know.

By Strider (Strider) on Wednesday, June 16, 2004 - 01:20 pm: Edit |

is 10 the answer?

nah, nevermind

By Astrix (Astrix) on Wednesday, June 16, 2004 - 01:22 pm: Edit |

25

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 01:22 pm: Edit |

then T2 would be equal to 5/3, not an integer.

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 01:22 pm: Edit |

10 is not the answer - please try again. "If you would like to make a call, please hang up and try again." I need to get a REAL job!

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 01:26 pm: Edit |

25 works, but is it the lowest one i wonder.

i'm going to work backwards, starting with t3, is that how u did it astrix?

By Strider (Strider) on Wednesday, June 16, 2004 - 01:26 pm: Edit |

is 25 it?

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 01:27 pm: Edit |

heh strider, it's okay. you got the 39 first :-p

astrix, how did you do that?

i'm assuming u worked backwards starting with the lowest values of t3?

yea, values of 1 and 2 for t3, do not work, good job astrix!!

do all of you people have AIM?

By Astrix (Astrix) on Wednesday, June 16, 2004 - 01:34 pm: Edit |

It had to be 1 more than a multiple of 3. I started with 13 but that didn't seem to work.

Some weird logic made me jump straight ahead four multiples of 3 to 3x8=24. So hit on 25.

It worked, I posted.

maybe he's mad that astrix got the question right? no, i'm kidding.

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 01:51 pm: Edit |

Sorry for the delay -- I was relishing my sub sandwich from down the street.

25 is the correct answer -- once again Astrix got that question.

Try out this question: A certain item sells for $9.60. However, if a customer wishes to buy more than 20 of these, the price per item is reduced by 15 cents for each item beyond the 20. (For example, a customer who bought 26 of these items would pay $9.60 - 6($.15) = $8.70 per item.) For what quantity (of this item) purchased by a customer will the store owner receive the largest revenue?

By Titanz05 (Titanz05) on Wednesday, June 16, 2004 - 01:55 pm: Edit |

If he buys an infinite amount.

Hey does anyone else's collegeboard homepage say...

"Check back on June 28 for June 5 SAT scores."

I'm pretty sure it is a typo.

By Strider (Strider) on Wednesday, June 16, 2004 - 01:58 pm: Edit |

42 is the answer, right?

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 01:59 pm: Edit |

i got 10 but am pretty sure its wrong

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:00 pm: Edit |

i know where i messed up hold up

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:01 pm: Edit |

i got 43?

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:02 pm: Edit |

i think 42 is correct i made a stupid addition mistake is it right ets?

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:03 pm: Edit |

yes just checked 42 is right did u all set up an aim chat?

i have a question is the first derivative and limits considered advanced math or calculus bc i learned those two before how to do that problem bc i used first derivative to figure it out and if that is whats on the new sat ouch that sux thats pretty advanced stuff compared to the old sat

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:09 pm: Edit |

june 28th is when they mail them, u can check them online definitly by friday and probably sometime tomorrow they will be up

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 02:09 pm: Edit |

Good job -- the answer is 42. I am curious to know how you went about solving this problem -- after you share with me your method, I will tell you my method.

By Strider (Strider) on Wednesday, June 16, 2004 - 02:10 pm: Edit |

really? i just set up a parabola for that last problem

By Strider (Strider) on Wednesday, June 16, 2004 - 02:10 pm: Edit |

and then i found the maximum

By Astrix (Astrix) on Wednesday, June 16, 2004 - 02:11 pm: Edit |

EDIT damn why can't cc update sooner

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:11 pm: Edit |

ok i used first derivative first u have to get the equation i used f(x)=(x-20)*(9.60 - .15x) then taht gives u f(x)= -.15x^2 + 12.6x - 192 then i used the first derivative to get -.3x + 12.6=0 then solve and u get x=42

By Strider (Strider) on Wednesday, June 16, 2004 - 02:16 pm: Edit |

suppose we can start a new thread? maybe that would help? and this one is getting long anyway?

By Astrix (Astrix) on Wednesday, June 16, 2004 - 02:18 pm: Edit |

I dunno if someone's already posted by the time this gets posted umm but here:

If x is the number of items & R is the revenue he gets

R(x) = x(9.6-0.15(x-20))

You find R'(x), put it equal to zero to get the roots.

42's a point of maxima.

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 02:19 pm: Edit |

but we're not expected to know calculus, although that's a fairly simple thing with calculus. is it fine if it is plugged into a calculator, like the ti-83 and calculated at the local max?

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 02:20 pm: Edit |

why would u need the zero to get the roots, wouldn't the zero reveal the maxima?

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 02:20 pm: Edit |

The method used is a combination of Strider's and Shizpit's approach.

Let x = # of items beyond 20.

Revenue = (20 + x)(9.60 - .15x)

Revenue = 192 + 6.60x - .15x^2

The graph is a parabola, maximum R at x = -b/2a = (-6.60)/(2 * -.15) = 22.

Answer is 20 + 22 = 42.

OK, LET'S MAKE A NEW THREAD, I'M STARTING TO NOTICE THE LAG SIGNIFICANTLY NOW.

By Shizpit (Shizpit) on Wednesday, June 16, 2004 - 02:21 pm: Edit |

yea but the problem is u are supposed to be able to take the test without the calculator and i don't even know if i would consider it calculus i am taking cal ap next year i took advanced math and trig this year and we covered that so i dunno but it was in the 4th quarter when we covered it, lets see what ets has to say

By Joshjmgs (Joshjmgs) on Wednesday, June 16, 2004 - 02:22 pm: Edit |

Shiz, you dont you didnt HAVE to multiply then together, you could have just taken the derivative as is.

its:

d(x-20)/dx*(9.6-.15x) + d(9.6-.15x)(x-20)

9.6 - .15x - .15(x-20)

-.3x + 12.6 = 0

x = 126/3 = 42

By Altf4 (Altf4) on Wednesday, June 16, 2004 - 02:23 pm: Edit |

ets, what is -b/2a called, is that a formula for finding the maximum?

By Strider (Strider) on Wednesday, June 16, 2004 - 02:26 pm: Edit |

I just made a new thread~

By Etsrep78328 (Etsrep78328) on Wednesday, June 16, 2004 - 02:26 pm: Edit |

-b/2a allows you to find the axis of symmetry of a parabola, or the x-coordinate of the vertex of a parabola in the form ax^2 + bx + c = 0.
