<p>what did you guys get for the total number of towels in the closet?</p>
<p>I have a shrew hunch the answer was 15.</p>
<p>yay, that’s what i got.</p>
<p>i also got 15 for the towel question.</p>
<p>same 15/6=5/2</p>
<p>Can anyone remember what the beehive and the school population questions were? I’m looking at the answers but they don’t seem too familiar.</p>
<p>Beehive: 30
School population: [(110-2x)/(100)]P</p>
<p>for the person who was asking about the 3y=x-12 question that asked for teh inverse…at first i thought it looked like none of them were the inverse to, then i realized you had to divide both sides by three to get it into standard form of a line. after you did that the negative invesrse was in the answer choices…i dont remember the exact numbers in the problem but i rmemeber thats how i got the answer…</p>
<p>and dammit i made the same mistake as R.C with the ! and III question with 6 and 7 being the answers when n was added to the set, i thought 6.5 was in it too, stupid careless errors grrrr…</p>
<p>Okay, I remember neither the beehive nor the school population. Maybe I somehow forgot to do those questions? lol I hope my scantron isn’t off by like two questions…</p>
<p>was that experimental?</p>

<p>i thought N was n<12 or something</p>
<p>i think the slope of the perpendicular line was three, i put the other ones into my graphing calc. and they werent perpendicular, so i panicked and realized i had made a mistake…so the answer was something like 3x-6 or something.</p>
<p>Yeah, I got 9% for an answer, to whoever asked that earlier. That was the one where the length increased 30% and the width decreased 30% – and it asked for how the area changes. I substituted numbers in and got 9%</p>
<p>It seems that neither were. But maybe there are different versions of the same test/form, as foxshox mentioned earlier?</p>
<p>was it just me or did this test requre pretty little use of the calculator? like other than a couple, the vast majority could be answered through logic/simple algebraic functions?</p>
<p>9% is right.</p>
<p>So decreased by 9% for that one? Was it choice D or E?</p>
<p>Just2fits- i was talkin about the question that said somethin like if n is added then what integers can the median be…or somethin like that… 6 and 7 and 6.5 were possible but i didnt read it carefully to see that it asked for only integers…</p>
<p>Cendiaz - yea the slope of the perpendicular line was 3…i remember the answer i just dont remember the original equation…all i know is that you had to divide both sides by three, because how the equaition was presented it looked like the right answer wasnt there…</p>
<p>The baseball color thing was clearly 25.</p>
<p>The problem said:</p>
<p>“5 colors, 2 spots, how many Different DESIGNS!”</p>
<p>Never stating that the two colors couldn’t be the same.</p>
<p>Here’s all possible:</p>
<p>AB BA CA DA EA
AC BC CB DB EB
AD BD CD DC EC
AE BE CE DE ED</p>
<p>AA BB CC DD EE</p>
<p>25.</p>
<p>it did say two distict colors…</p>
<p>***? Are you sure? I remember reading different only once in the problem. I have no recollection of reading “distinct” Can anyone else remember?</p>
<p>If it did, I probably wouldn’t have changed my answer from 20 to 25. </p>
<p>I got 20 at first by doing 5 x 4 like any other permutation problem in 15 seconds. I went over the problem again though and realized that the colors could be the same.</p>
<p>I’m pretty sure it didn’t say distinct. It would be hard to word if it did.</p>
<p>“How many different combinations can be made using distinct colors?”</p>
<p>I’m pretty sure it didn’t say that. :)</p>
