<p>I wonder if it’s just us college confidential folk that are smart… am i the only person here who got 45/75 on the science :(</p>
<p>well i thought the science was pretty easy except for the weather section cause ive never learned that stuff before</p>
<p>can we come up with a list of the answers? I’m like freaking out here</p>
<p>@master of puppets</p>
<p>um i think i may have gotten even less than that :(</p>
<p>What did you guys get for the perfect square one? I skipped it cause I couldn’t figure it out /: Was it 0.1?</p>
<p>haha @masterofpuppets, columbia '17 :D?</p>
<p>can we try to compile a list for the awnsers to the challenge math— i need to know this is my only shot of getting in</p>
<p>@ thehutis yes… my dream is columbia but i fail at science :</p>
<p>@pokemonwhite okay, well to start off, i got -1 on the first question.</p>
<p>compile awnsers for challenge math persey?</p>
<p>and are you guys mostly freahman like me or seniors because i feel like some of you did much better than me – only 12/15 on chalenge math</p>
<p>I rmbr the answers being
pi
(-4,0,4)
864
1/4 > x > 4
16/3
2.5
3 false
480 cubes (faces?)</p>
<p>um… i got 488</p>
<p>prob 48/50, 55/75, 12/15… prob not gonna get in</p>
<p>I think the answer was 488 cubes because you had to add in the 8 corner pieces that you subtracted more than once. Does anybody remember that question?</p>
<p>yea cuz if you go side to side you get 100 + 90 + 90 + 80 + 64 + 64</p>
<p>i got 488 also</p>
<hr>
<p>question was 100 units cubes turn into 1 cube that was 10 by 10 by 10 and surface is painted how many cubes have at least one face painted</p>
<p>WHAT DID U GUYS GET</p>
<p>ill right my explanation for 488 in a min</p>
<p>10^3 - (10-2)^3= 488</p>
<p>I got .065
If I understood the question correctly.</p>
<p>a number from 1-50 has p percent of being chosen
while 51-100 has 3p of being chosen
Since they must add up to 100, it’s 25% and 75% respectively</p>
<p>Now for 1-50, there are 50 numbers (be careful how you count here) and 7 perfect squares: 1, 4, 9, 16, 25, 36, 49
7/50
now multiply that by 1/4 to get 7/200</p>
<p>for 51-100 there are 2 perfect squares 64, 81
2/50
multiply by 3/4 to get 6/200</p>
<p>add them to get 13/200</p>
<p>wait…correction: 100 is a perfect square, as the problem said something like no greater than 100, so it’s .08?</p>
<p>@masterofpuppets</p>
<p>didn’t mean no disrespect sir! 
I’m sure you’ll do fine, you’re probably VERY good at science and don’t even realize it!</p>
<p>If you want to go to Columbia for science, might I suggest that you work at a lab to show your dedication to learning?</p>
<p>@ starwing</p>
<p>i did something similar to yours and I got .065 including the 100 so i guess we’re both right?</p>
