<p>was the 1/108 question in the experimental math section?</p>
<p>Once every 8 SATs</p>
<p>@wagsthedog: usually no, if you get any math question wrong, you can’t get an 800. But if the test is extremely hard, the curve changes so sometimes (rarely though), you can get an 800 even if you got one question wrong.</p>
<p>"Mike,
you’re right. it’s 216/6=36. If order didn’t matter, which I’m starting to feel that it didn’t, it’s 1/18.</p>
<p>but was the question how many ways you can get a 17,18? "</p>
<p>No. Order doesn’t matter, hence it’s 36, not 72. Therefore 1/18. You’ve confused it all up. Read my post again.</p>
<p>Guys,
I looked up a thesis invovling dices and sums. The paper stated in a table that there are 216 possiblities with 3 ways to get 17 and 1 to get 18. Hence, the right answer is 1/54.</p>
<p>Also, was the section with the 7 letters/password in one of the math section for those that did not have an experimental math section.</p>
<p>I’m guessing the 1/108 question wasn’t in the experimental math section???</p>
<p>my friend who got an 800 on math last time (and 800 on math II subject) just got 1/54 for the dice one… “order matters”</p>
<p>^Except order doesn’t matter. You obviously didn’t read the question.</p>
<p>ok so what answer do you think it is?</p>
<p>@dice question: Screw it. QAS comes out in a month. I’m pretty sure its 1/18 now (and I got it wrong). It depends on the exact wording of the question, and I don’t think we remember it word for word.</p>
<p>Dice was NOT experimental.</p>
<p>I got 1/108. But I definitely could be wrong. I tried a bunch of stuff on my calc so I forget how I got my answer.</p>
<p>order doesn’t matter. so its 1/54. i got it wrong.</p>
<p>did I say order mattered before?</p>
<p>yeah thats also what i got boston, maybe i told my friend the wrong wording</p>
<p>nah it’s 1/54
order does matter because there are 3 different ways to get 17, and only 1 way to get 18. that means that out of 216 possibilities, 3 will give you 17 and 1 will give you 18; so you have a 4/216 chance of getting 17/18
4/216=1/54</p>
<p>if order didn’t matter, then you would only have 18 possibly rolls, not 216</p>
<p>My version of compiled answers:</p>
<p>10<x<14…obtuse triangle one
119…BRGY Pattern
5/3 …find the value of 3x
1.2…radius of each circle
24…combinations for band
1/54…3-Dice probability (if you don’t believe me, google it!)
6000…don’t know what this is for but it came up as an answer in this thread many times
8000…difference from july
15…$1 paperback books
11-3x-y
18???..a curved scatterplot going up to 20 (units of time, whatever they were)
f(v)-f(t)…difference between max and min
8???..px + 6x = 14x, solve for p…or maybe it was px + 8x = 14x…don’t remember exactly
7…x^-y = 1/8 and y^z = 243, 2+5=7
y = x/root 3
225…for hall B (there were 45 freshies)
12…area of 5-5-6 triangle
I and II only…parallel and perpendicular lines
2…g(x) = x(x-1), g(m+2) = 12, solve for m
1080…hours the kid spent studying
8 root 2…square’s diagonal</p>
<p>And did anyone get 1 for the height of a rectangular box? Volume was 1 cu. unit, length was 2 and width was 1/2…???</p>
<p>Please add on.</p>
<p>I got 1/108… But who knows!</p>
<p>But on the Red Blue Green Yellow question, I got 118, not 119. But i think i just messed up. I said 116=1 (mod 4) but it should be 117=1 (mod 4). DANGIT.</p>
<p>Im pretty sure it was 290 for hall b… anyone else confirm?</p>
<p>Screw the probability one. I hate probabilty. I’ve never understood it. Haha. What about the one that was like, x^2 + y^2 = a and xy = a - 10, what is (x+y)^2 in terms of a? I THINK the answer was 3a - 20. I asked two different people and that’s what they got. I’m not so concerned with what it was but HOW IN THE WORLD do you get it? I tried forever to get it, but I couldn’t. Anyone know?</p>
<p>I’m waiting for someone really good at math to come up with an elaborate explanation for the dice problem, that involves several methods. Until then I shall remain skeptical about 1/108 and 1/56.</p>
<p>everyone here is ■■■■■■■■. the answer is 1/54. I was in the USAMO for 3 consecutive years. now was 6 an answer choice (not the right answer) for the 5 5 6 triangle?</p>
