<p>The cube was 6 square units I believe.</p>
<p>the chairs was easy.</p>
<p>put one girl in any arbitrary position. then, there are six acceptable arrangements that exist (such that the second girl is not in the same column or row as the first.)</p>
<p>there are twelve such positions for the first girl, so the answer is 12*6 = 72.</p>
<p>ooo ya i remember that 1</p>
<p>But did you have 4 math? Im praying the cube wasnt experimental- but I had 2 completely multiple choice math sections, and they were both 25 minutes. One had the cube, another had a question about retirement with inequalities.</p>
<p>i dont know if this has already been discussed...but the one about the phone calls at 6am and 6pm? ***?</p>
<p>Yeah, I got that one as well.</p>
<p>I put "arrest" even though it seemed too obvious.</p>
<p>why 12- i thought it was 16</p>
<p>Whichever one is 12 hours later.</p>
<p>yup, i got 72 for the chair girl one too... watd u guys get for the functions one... the last grid in...</p>
<p>and btw i had 4 cr and 3 math and i had the cube so the cube wasnt experimental and i got .5 for the cube... i had two 35 question cr so one of those was experimental...</p>
<p>o i got the phone call one i think, but i dont remember the answer sorry</p>
<p>f(10) was 54.</p>
<p>cube is .5. in a 2x2 cube, each cubie has three visible sides and three not visible sides. paint the exterior and you've only painted half the faces.</p>
<p>f(10) = 3f(7) = 9f(4) = 27f(1) = 27*2 = 54</p>
<p>i had 3 math, 4 cr.</p>
<p>why did u guys get 72 for the chair one- i thought it was 16 times 6</p>
<p>there are twelve chairs in a 3x4 matrix. problem stipulates that they can't be in the same row or column. thus, for every possible position for girl 1, there are six acceptable positions for girl 2</p>
<p>did anyone have a section with the last question being like - which number, if removed (or added?) would result in an average of like 30 or 70 or something? If so, do you think it was experimental?</p>
<p>there were 16 chairs tho- thats how u got the 6 positions</p>
<p>I did not have a math section with either the girl/chair problem, or the cube painting problem</p>
<p>otherwise w/ a 3 by 4 it would have been 4 acceptable positions</p>
<p>xxxx
xxxx if girl a sits newhere...
xxxx </p>
<p>axxx
xxxx then b can only b in...
xxxx </p>
<p>axxx
xbbb so there are 6 places she can sit... 6 times the 12 places<br>
xbbb person a can sit is 72</p>
