<p>AH yes, the number line one. That one wasn't experimental. The given point is approximately -0.8, and the question asked you to multiply it by -2, so the answer is the point that's approx. 1.6. That was choice D I believe. It was the rightmost point in the line.</p>

<p>Maybe I was right, then, because I think I chose something that was in between 1.5 and 2. Thanks</p>

<p>Ugh, you know the question where it was like two digit numbers with units number as a 5 that are prime? I got that wrong, cuz i counted 5 :(</p>

<p>Haha...email CB and say that 5 is a two digit number when we are using a fixed digit system with the whole number side fixed at 2 digits.</p>

<p>I think (but am not positive) the question was: SET A = set of positive prime integers; SET B is the set of positive integers with 5 in the units digit. SET Z is the set that contains numbers in both SET A and SET B? Why would the answer not be zero? I also think this was an early question in the section, hinting that it might be straightforward. Anybody remember?</p>

<p>It was zero. Some people just overanalyzed it and counted five (05), and said one.</p>

<p>lol, *** "05" is a 2 digit number? lmao</p>

<p>wait, did all of you guys have the problem where they tell you C is midpoint of A and B, and so on? </p>

<p>not the one where they give you points on a line, and multiply by -2 or something</p>

<p>i had a problem where they mentioned a bunch of midpoints and gave the lengths of some of them...etc. I think the answer was 17..I don't if thats teh question you're talking about though.</p>

<p>yes, both of those were part of the REAL test</p>

<p>wait, the number line one where you multiply by -2...wasn't the rightmost point (1.6) choice E? Cuz I remember choice A was the left most point, and it went up the alphabet as you move right.</p>

<p>OK--- i got 89 for the first answer to the student response questions. Does anyone remember what this problem was about or if 89 is even the right answer?</p>

<p>i had difficulty with one problem:</p>

<p>R is the midpoint of PQ, and S is the midpoint of PR. T is any point between Q and R. If PS is 9, and ST is 19, then what is TR?</p>

<p>i believe it was something along those lines, although i have a really bad memory.</p>

<p>choices were:17, 18, 19, 20, 21</p>

<p>P|---------T---------R-S-----------------|Q Somethin like that?. I think:
PT=9, PS=10, What was SQ? Im pretty sure 17 was the right answer</p>

<p>there was another question on:</p>

<p>A gym invests in 4 workbenches priced at $1700 each. Then, they also buy 8 at $1300, and "X" amount of $1200. The average amount was 1300. X was supposed to be an odd, whole number, but i kept getting 16 because 4 workbenches at $400 above average came to $1600, and to even that out, you needed 16 of $100 under the 1300-average.</p>

<p>someone please help?</p>

<p>I think the workbenches one was experimental.</p>

<p>Yea I didn't have that problem either. But I did get 89 to the first student-response question. Does anyone remember what that problem was about?</p>

<p>i dunno but i got it also.</p>

<p>what about the question with the average value of 10 "things" (cant remember) set at 88, but then a few numbers were incorrectly inputed, and so it asked for the "correct average" ?</p>

<p>I got 85 as the correct, re-calculated average.</p>
