December 2009 Math II Discussion

<p>It’s not gonna make a difference if the question said INCLUDES. Most of us just misread it in that case.</p>

<p>the bacteria question was 13780,6</p>

<p>the phase shift to the right was 2sin(2x-pi/2)</p>

<p>@Rishmeister and 800orBust
The correct answer was explained a few posts ago. The question and its answer are completely correct. Please stop making these ignorant posts.</p>

<p>can sum one Tell me tht WHAT IS The nth term of tht question
THT b(n) da n was below b and on da right side
How can we Do it ??</p>

<p>Does someone remember a q with the answer log 10 (base 5)</p>

<p>Yes, that’s the answer I picked.</p>

<p>yo guys how bad is 750 on this?! will adcoms be like “meh, he took it, so w/e” or “Damn, this is a detriment to this app!”?</p>

<p>do u think -9 on raw score can get 770</p>

<p>^-9 is probably anywhere between 750 & 780</p>

<p>One of the questions on the Math subject test was:</p>

<p>Which interval of x contains all the values that satifies the equation x^2 < 4</p>

<p>We all know that the answer should be (-2,2) but that was not an answer choice. Some of the possible answers were (-3,3) and (0,2). Personally, I chose the latter since every value in that interval satifies the original equation, however, it doesn’t include everything in the domain. Some kids are saying that although the former has values that don’t satisfy the equation, it still contains all the possible values which could satisfy it.</p>

<p>This question should be removed on the grounds that it intentionally attempted to confuse students. It is fine if they want to try to trick students with trick answers, however, I believe that the wording was such that you can make the argument that all of the possible answer choices were wrong, including (-3,3). The wording of the question was so equivocal and so open to interpretation that there is no way you can come up with a universal consensus. Even if you showed all of the students the question again, and explained to them what you perceive as the right answer, I guarantee there will still be a large number of students who would disagree.</p>

<p>This a math test, not an english test. The exam is designed to test our math acumen and colleges acknowledge it as such. They therefore have a responsibility not only to the colleges, but also to us, to test the appropriate subject, i.e. MATH. Stunts like this is just one of the many reason that many colleges are placing a decreased amount of emphasis on the SATs and SAT IIs.</p>

<p>I understand why people believe the answer was (-3,3) but I think the argument can still be made that this answer was wrong based strictly on the wording.</p>

<p>Join the war against College Board and complain today! UNITE</p>

<p>P.S. Who ever said that “this plan isn’t going to work” is either a defeatist or a pessimist. That type of attitude will not get you far in life. We might as well try!</p>

<p>great!^^ how do I complain? I mean is there a particular ID or forum</p>

<p>Two Questions:</p>

<p>First, what is the answer to the question about how many lines intersect in an (x,y,z) plane? And please explain your reasoning.</p>

<p>Second, the for function 4x^3 - 3x^2 +1 (something resembling that) question, what was the answer. And does anyone remember the function exactly?</p>

<p>Thanks</p>

<p>Which interval of x contains ALL the values that satifies the equation x^2 < 4.</p>

<p>Is there still any room for argument?</p>

<p>Twaan - The answer for your first question is infinitely many. Try picturing a pencil rotating around a pencil. There are infinite angles for this in a 3D plane. For your second question, the consensus was 2. 1 was a root and the rest were imaginary.</p>

<p>Are you sure it wasn’t “Which of these intervals satisfy the equation x^2<4”?</p>

<p>Edit - Btw, I have the official SAT Math 1 and 2 book. The book has 2 math 2 tests. On one, the cutoff for an 800 was 44. On the other, it was 43. I guess it varies. These were from previously administered tests, so it really depends!</p>

<p>don’t you remember in this question with r & q, were there both q and -q as answers, or only -q?</p>

<p>For the 4x^3 or something one I just solved the equation in my calculator to find that there were two non-real roots.</p>

<p>@ahsanxr But we don’t know if it said all. Some people say it did, and some say it didn’t.</p>

<p>I think it did. Because if it hadn’t then none of the answer choices could have been correct, which cannot be the case.</p>

<p>If it said which interval satisfies x^2 < 4, then (0,2) would work.</p>

<p>In either case, what’s done is done. We’ll just have to wait and see.</p>
