October 2010 Math SAT Thread

<p>i got:</p>

<p>X^2 > y^2 3/5
1/108
119
290
15 paperback
5 toothpick
RP = 8
circles w/radius - lenght of diagnal = 8 root 2
8000 less in july
6000 comp
m = 2
3a-20, i think i put that
any more?</p>

<p>@xAlex452, each test taker has an experimental section (CR, M, or W.) Basically, only 3 sections get scored for each subject, so whatever one you got 4 sections of (for me, I had 4 W,) one of those is experimental.</p>

<p>last time i took SAT math, i got 770 with -1 (rated easy) -___-
Probably the same for this test in my opinion. SAT math this time wasn’t too terrible difficult. I expect:
-1 770
-2 750
-3 730</p>

<p>The die problem, plural form of dice.
I thought of it as 1 dice being rolled 3x in a row.
Question said it need to equal 17 or 18.
Meaning it needed 6,6,6 or 6,6,5.</p>

<p>I let roll #3 be the 5 or 6.
Roll #1 odds are 1/6.
Roll #2 odds are 1/6.
Roll #3 odds are 2/6 or 1/3.</p>

<p>1/6<em>6</em>3 = 1/108</p>

<p>wat was the answer for the one saying
the number of people who liked both TV program A and B?</p>

<p>do u guys remember?
neither was 7 people A was 50 people B was 42? people
there were total of 78 people surveyed</p>

<p>27 both teddy</p>

<p>okay i think i put that… phew.</p>

<p>i have to give up early decision if i miss more than 2…</p>

<p>@teddybear52,
The answer was 27.
78 - 7 = 71 (remove the 7 from the group)
56 - 27 = 29 (i forgot how i found 27)
42 - 27 = 15 (i forgot how i found 27)</p>

<p>29 + 15 + 27 = 71 (both + A + B = total viewers)</p>

<p>PLEASE tell me section 4 was the experimental one…</p>

<p>^^ I got the same as Avid. It just said three dice. If we set each of them as a possibility to get 2/6, that’ll end up badly of course. So, it was ambiguous. All you needed was one of them to have a chance, so I decided to do what Avid did.</p>

<p>avid is correct, i got that too</p>

<p>what was the experimental math section?</p>

<p>I had two gridins, one with the question about the halls and lockers and the other with the questions about obtuse triangle being between 10 and 14?</p>

dice- 1/54 guaranteed</p>

<p>For the die problem I got 1/54. How I thought of it was there were 4 possible ways to get 17 or 18. 6,6,6;5,6,6; 6,5,6; 6,6,5. Now that I think about it though, it’s possible that I misinterpreted the question…anyone remember the exact words?</p>

<p>was the one with x^-y=1/8 and y^z=243 experimental?!?!?!?!?!?</p>

<p>No I only had 3 three math questions and the shaded rectangle one was on one of them. That section isn’t experimental.</p>

<p>check the link- I don’t see how the answer could be different from what is on there</p>

<p>@Rennir: What is the probability of getting a sum of 17 or 18?</p>

<p>I don’t think so…which section was that? The experimental was one of the grid-in ones, I’m leaning towards the second grid-in though.</p>

<p>someone answer my question!!!</p>
