December 2009 Math II Discussion

<p>just a little rant… im at like -4/-5… hopefully this is still an 800 and everything else is right… hopefully.</p>

<p>must be 49, cause i attempted till 48 and didnt come across it</p>

<p>please let it get thrown out!!! I didn’t have time to finish the test so that would be one less blank/omit for me!!!</p>

<p>I’m pretty sure it asked for the mean of the <em>frequencies</em> but I am also not 100% sure.</p>

<p>Yes! Everyone please e-mail collegeboard about it! If there are enough complaints we’ll all benefit, so I don’t see a reason not to!</p>

<p>Also… totally stressing out about the frequency problem. Were they asking for the mean of the data or the frequency? If they didn’t specify they should throw that out too - _ -</p>

<p>I’m pretty sure they were asking for the mean of the data set.</p>

<p>Somebody come up w/ a general statement that we can submit( but write in our own way) about the question so that CB will get the point & thrwo it out.</p>

<p>Question 36ish, the one with 3x-2 function equaling x: (x-2)/2 (Choice E)</p>

<p>-Question 41: 3 (Choice D) – probably got this one wrong</p>

<p>-Question 42: 5.82 (Choice E)</p>

<p>-Question 45: Statements I and III were true</p>

<p>-Question 50: 2 (Choice B?)</p>

<p>-Question that had the table of frequencies and had the frequency of 4 equal x — that should have been “x = 4”</p>

<p>-Question that said the center of the circle is at (0,6) — I said -8 and 8</p>

<p>-Question that said “if 14 and 10 are removed from a set of numbers equaling 240, then what’s the remaining average … blablabla” — the answer was 21.6</p>

<p>-Question that asked the frequency of the sine graph — freq was 1/pi</p>

<p>-Question with probability - 7/15</p>

<p>-Question about what doesn’t change - standard deviation</p>

<p>-Question about r and q thing - negative q</p>

<p>-question with weird function: (0, z, 0)</p>

<p>-Question with someone driving and someone else driving to catch up: (Choice A) (sorry, forgot the actual answer</p>

<p>-Question with geometric sequence: n^2 + 2</p>

<p>-Question with 2 lines and they asked what are the points equidistant: 2 perpendicular lines</p>

<p><a href="mailto:satquestion@info.collegeboard.org">satquestion@info.collegeboard.org</a> </p>

<p>That is the email to report test ambiguities. It says to report it to the supervisor before leaving the test center though.</p>

<p>For the driving one, I got something like |50t-10| or |50t+10|</p>

<p>I omitted the one where f(2)=-3, f(4)=6, what’s x for f(x)=0??? Can ANYONE help me on this one??</p>

<p>And can someone explain why the cubic function had 2 nonreal roots? I either put 1 or none…</p>

<p>which question are we trying to throw out? the x=4 or the [-3,3] one? i got [0,2] for the interval question…</p>

<p>remember not to mention cc on the email! they cant find out about us
mullbeeryy i got like l10t-50l</p>

<p>Guys, College Board isn’t going to get rid of a question just because some pretentious kids from college confidential want an 800</p>

<p>Dear Collegeboard,
I took the SAT IIC Math Subject test on December 5th, 2009. Number 4? on the exam was extremely ambiguous. It asked for the set of x values that would satisfy the equestion x^2 < 4. The correct answer would have been (-2,2) but that was not one of the options available. There were two conflicting answer choices that brought me much confusion. One of them was the set of numbers (-3, 3), and the other was (0,2). While (0,2) satisfies the equation, it doesn’t contain all the x-values. (-3,3) contains all the x values that satisfy x^2<4 but it also contains extra values that do not fit. The wording of the question and the tricky answer choices may have misled many students such as I to put down an incorrect answer choice. It would be great if you could look into the matter, and possibly consider throwing out this question. Thank you for your time.</p>

<p>Um… something like that. Try not to copy and paste it though or they might start to disregard the emails…</p>

<p>“”“I omitted the one where f(2)=-3, f(4)=6, what’s x for f(x)=0??? Can ANYONE help me on this one??”“”“”</p>

<p>the graph has to cross the x axis somewhere between 2 and 4… so i put 3…</p>

<p>@mulberrypie</p>

<p>for the cubic one - if you graphed the equation, you could see that it had only one real root. Since it is cubic, you know that there must be three roots total, so two of them must be nonreal.</p>

<p>vanilla: i think we’re trying to throw out the interval question. x^2 < 4 [0,2] vs [-3,3]</p>

<p>I forgot what was the question about driving but it was definitely choice A</p>

<p>edit, this is Math II, not math II C</p>

<p>for the one on the top i just put f(3) cause it was between f(2) and f(4) lol</p>

<p>nff, same thing here lol</p>
