<p>@steve On a recent collegeboard test a raw score of 40 is 760</p>
<p>i remember that one steven, i still have the data in my calculator, and the answer was 4.93 i think</p>
<p>the one im talking about was like before number 30 i think so it might have been an easy question but im doubting myself because a few pages back, i saw something about the number of intersections and idk if thats the same question</p>
<p>what the… metalliyanks…really…dam then ill get 800 for sure then…</p>
<p>@abc12311580 - Yeah I think I vaguely remember 4.93 as an answer too</p>
<p>oh wait you are right…sorry if you felt some sort of offence there…didnt mean to say ur score is low…i probably got 40 raw too</p>
<p>Wasn’t ((square root of 2) * pi) divided by (4) the answer to the rectangle question?</p>
<p>^that seems to be the consensus, yes.</p>
<p>@stevenydc, you put the x values in a list, and y values in another list, then you use “QuadReg” and it gives you the parabola that best fits.</p>
<hr>
<p>Anyways, for the prime question, does anyone remember the exact wording? Did it say that the numbers generated from 2k+1 would all be prime or that all prime numbers can be made from 2k+1? I might have misread that one. If it was the 2nd thing I said, I got it wrong…</p>
<p>Also, I skipped 1 question out of all of them. There was a question that said f(x)=g(x)(x-2)+r and asked to find r, but all the answers were given as f(n), and I was too low on time to answer it. What were you supposed to do?</p>
<p>@rover112 - Yes, it was. The square root of 2 * pi / 4 is approximately 1.1</p>
<p>@800math800 - The function was f(x) = g(x)(x-2) + r and asked what function would give you just the value r. If you did f(2), then it would end up as f(2) = g(x)(2-2) + r, with the (2-2) equaling zero and consequently also turning g(x) into 0 regardless of its value, leaving “r”. The answer was f(2).</p>
<p>Oh, good. Everyone’s saying about 1.1 is the answer, but I remember choosing an answer that wasn’t solved out. Just making sure I didn’t overlook anything or make a stupid mistake.</p>
<p>@ steve No problem. The 3 I got wrong so far were all misreading the question cuz of time contraints</p>
<p>800math800, where do u put values in?</p>
<p>@800math800- same deal for me. i said that the fact that all odd numbers are not prime disproves the statement or whatever. i guess i misread it, too…</p>
<p>@800math800 - The prime statement was all primes can be written in the form 2k+1 if k is an integer, ex. 13=2(6)+1. The answer was “2 is prime” because 2 cannot be written in this form.</p>
<p>That **** was HARD!! </p>

<p>That prime number question was soooo messed up because at least 3 of the answer choices disproved the statement</p>
<p>^actually, they didn’t. i, too, thought that at first, but after really deciphering what they meant, the “2 is a prime #” one was really the only one that made sense!</p>
<p>Wasn’t the answer to the prime number one something like 2(7)+1=15 which isnt a prime number?</p>
<p>Yeah how come the 2(7) + 1=15 doesn’t disprove the statement?</p>
<p>I put the 15 too, because it said for all prime numbers “p” and 15 isn’t prime, but the one with getting 2 for p is also true :/.</p>
