<p>I rememeber III being right but i dont remember if i put I and III or just III. do you remember what I was?</p>
<p>and jjfine96 which two did you get wrong?</p>
<p>I think I was just something about x varying directly with y (but then the condition in the problem wouldn’t be that… so I’m not exactly sure).</p>
<p>Got the z-score one wrong, also the one where they gave a function and asked to find the biggest positive difference between the roots. I missed a negative sign in my calculator… lol.</p>
<p>i think the z-score one was halves cause the mean doubles and standard deviation stays the same so denominator is same and numerator is half</p>
<p>@yanks270
I got x^5-x^3+x=0, too, for the one where there would be the same solutions if x were replaced by -x, but I think that was (A), not (B)</p>
<p>I’m pretty sure that the z-score answer is that it stays the same, because z-score has (score-mean) in numerator and st. deviation in denominator. Since the scores doubled, so will the mean and st. deviation, so BOTH numerator and denominator are double what they were. </p>
<p>Can you remember the rest of the details to the question you got $550 as the answer? I think I got something else ($656 maybe?) and I want to try it again. The 15% of 600, $100 four times all seem familiar, but there’s something missing.</p>
<p>@jjfine96:
I got 1.4 for the difference between zeros. Do you still have the function stored in your calculator? I want to check my answer.</p>
<p>@docseven:
The 52.5 you remember was the answer to the speed question. That’s what I got, too.</p>
<p>And the f<0 was the answer to the question that said f and |f| had no points in common.</p>
<p>I don’t remember the question with answer pn is even. Can you remind me what the question asked?</p>
<p>Some other answers I got–can anyone confirm these?</p>
<p>3/20 for the probability question</p>
<p>{-1, 1/2, 2} for range</p>
<p>I also remember that there was an easy question about MIDPOINT and an easy question about a CYLINDER, but I don’t remember the answers. I could probably tell if I got the same answers, if people tell me what they got.</p>
<p>did u guys use PR anyone?</p>
<p>i think the pn question said that p and n are integers and p is even so which of the following answer choices are true. and i got pn is even</p>
<p>and i also got 3/20 and {-1, 1/2, 2}</p>
<p>for the midpoint question im pretty sure i put something like (1.5, 5.5) and i dont remember the cylinder question</p>
<p>Hey guys, </p>
<p>So did anyone else get x^5-x^3+x=0 for the one where x is replaced with -x? I mean, I thought that if all of the exponents of x is even then that would be the answer but none of the choices had that. So was that the answer? </p>
<p>Also, do you guys remember a question about bees swarming? Something about it starts with 1 square mile and then doubles each year. How many years does it take to get to 100,000? The highest answer choice was 11 point something years??? But that can’t be right… </p>
<p>Finally, is the midpoint problem you guys are talking about solved by finding the midpoint of the two points and then the midpoint AGAIN between the midpoint and one of the ends? So its essentially 1/4th of the segment.</p>
<p>@melzideril</p>
<p>Now I think you’re right about the z-score. I thought the standard deviation stays the same, but that’s not correct.</p>
<p>The question with $550 as my answer said something like the following: There is $600. Every year it is increased by 15 percent, and then $100 is taken away from it. How much money will there be after 4 years?</p>
<p>And I also got a probability of 3/20.</p>
<p>Hey Yanks, you mentioned that you missed 7 questions at the end of the last SAT2 test. That’s about how I did on this test. Do you mind sharing what you got?</p>
<p>Yeah sure, I got a 680 in May. I had to have gotten several wrong as well.</p>
<p>everyone: what books did you all use - besides barrons.
is doing tests enough to prepare for 750+?</p>
<p>so I’ll be retaking the test again in December. Does anyone care to help me recall the harder topics on this last test? </p>
<p>I remember there is standard deviation, probability… what else?</p>
<p>@leeplee2</p>
<p>The bees question was done by solving 1*2^x=10000, which gives approx 16.6. The highest answer choice wasn’t 11.something, but was (E), which I think was 17 (and not 16.6), but I’m not positive.</p>
<p>@Yanks270</p>
<p>Thanks for the info. on the money problem. I see why I got $565 now. I did it after only 3 years, instead of 4. If I’d done it one more time 565*1.15-100, I’d have gotten 550, like you did.</p>
<p>@leeplee2:</p>
<p>You asked for help remembering some other harder questions. They’re not all hard, but these are some other questions I remember:</p>
<p>I vaguely remember was one that had Roman numerals I to V, instead of the usual I, II, and III. </p>
<p>Then there was one that was similar to one of the practice problems in the College Board book which had |x|+|y|=p as an answer–that’s what I got at least.</p>
<p>How about that question with the pin and the circle and the string or whatever? That was confusing.</p>
<p>There was an easy amplitude question to which the answer was 5?</p>
<p>A matrix problem</p>
<p>An arithmetic sequence, where you had to find the fourth term</p>
<p>|x|+|y|=p had to do with the coordinates of a square. That’s what I got too.</p>
<p>Bees question was 16.6.</p>
<p>I think that weird Roman numerals one was I and IV, if I remember correctly. Not sure what it was about.</p>
<p>I had no idea what was going on in the circle and pin problem. Whatever answer I got wasn’t an option. That was another hard one.</p>
