I got [-4, -2, 0, 2, 4], as each one can only be either one or negative one.. you guys? Reply
 04-21-2012, 03:48 PM #1697 New Member   Join Date: Jan 2012 Posts: 8 I screwed up the last 5 challenge math questions because I forgot they were there ! I don't think I got much else wrong. Probably 49/50 math (I always mess up one or two), 72/75 science, and 14-15 on challenge math. I answered everything except the last 5 challenge math problems (D'oh). Do you think I got in? @Kappadesu I got {-4, 0, 4} because for you to get 2, three of the four terms would have to be 1, and only one to be -1. I made a list of all cases, and that's not possible.

 04-21-2012, 03:53 PM #1700 Junior Member   Join Date: Mar 2011 Posts: 44 yeah i got 898 too and i also got 4 0 and -4 for that one Reply
 04-21-2012, 04:04 PM #1701 Junior Member   Join Date: Jun 2011 Posts: 220 i answered the ones i knew id get 100% right which was... 50/50, 67/75 and 14/20. did you guys get -1 for the "i" 1/(x^2+x) one? and pi for the circle and |x| function? and 28 for the cents? and 2.5 for mi for third and second in the race?

 04-21-2012, 04:07 PM #1704 Junior Member   Join Date: Mar 2011 Posts: 44 btw i didnt get 6 for that one either i got 864 cuz they were in diff units i think Reply
 04-21-2012, 04:11 PM #1705 Junior Member   Join Date: Mar 2011 Posts: 44 anonymousx37 yeah i think i got -1 for that one, for the cirlce one i forget the exact answer but i was just 1/4 the area of the circle, i also got 2.5 for that race one, i also feel like i got 28 cents for one of them but cant remember the question Reply
 04-21-2012, 04:19 PM #1706 New Member   Join Date: Jun 2011 Posts: 7 I got 28 cents for that question, and 864 for the cube one (because there were different units, there were both inches and feet). Reply

 04-21-2012, 04:40 PM #1708 New Member   Join Date: Apr 2011 Posts: 25 Scores CCers, As a sophomore, I think I scored 60-63/75 science questions correctly, 49/50 easy math (darn R and E problem), and 16/20 challenge math. In your honest opinions, will i get in? Thank you and have a nice day. Oftheking Reply
 04-21-2012, 04:41 PM #1709 New Member   Join Date: Jun 2010 Posts: 29 I got pretty much the exact same score as the above person, and also as a sophomore. I hope I get in @_@. What did you guys get for the probability of choosing a perfect square, and also the sheep overall profit one? Reply
 04-21-2012, 04:46 PM #1710 New Member   Join Date: Apr 2011 Posts: 25 1. Probability of choosing perfect square, I got .08. Reason being you have 3/4*3/50 of a chance of choosing 64, 81, and 100 and a 1/4*7/50 chance of choosing 1, 4, 9, 16, 25, 36, 49. Thus, you answer is 16/200 = 8/100 = .08. 2. Sheep one was: (x+49*(x/700))/(x) = 107/100 --> 7/100 = 7.0 percent. Reply
