October 2010 Math SAT Thread

<p>Lol @ people arguing about the dice problem. It’s probability, and that problem involved permutation. No question about it. Order matters. 4/216 –> 1/54. /argument</p>

<p>i understand that the last question on the experimental section was the painted red cube problem. what did you guys get for it and what was the answer?</p>

<p>anyone know the answer to the absolute value(xy) problem?</p>

<p>Did you guys have a question where there were two perpendicular triangles sharing a side and the base and hypotenuse of one of the triangles was 2 and 3 respectively or something along those lines? I had that in section 4, and I had 4 math sections with two grid in sections. If no one had this question, then I think its safe to assume that section 4 was experimental.</p>

<p>The absolute value of xy could be every option except for 1, which was choice E.</p>

<p>the answer is 1</p>

<p>

</p>

<p>Are you sure it was 290? I read the question twice and remembered the question asking for the total amount of lockers in Hallway B…
(btw, @sAxsKy: I got 45 too)</p>

<p>@ kbbm24</p>

<p>I did the exact same thing you did and forgot the 6/9. I thought 2/3 * 3/3 = 6/15. There goes my 800 =(</p>

<p>how was it 119 and not 120 for the blue, red, green one</p>

<p>@CrzyGmer789X2 and gensis, Thank you.</p>

<p>green was the third one, so 3, 7, 11, 15, 19 and then you add 100 caz its a multiple of 4 and you can clearly see the formula thing is growing by 4 each time, thus 119.</p>

<p>■■■ there were 4. there goes my 800. did any of you have that triangle one i described b4?</p>

<p>

</p>

<p>Are you talking about the computer volume question?..because I got 6000,
Aug(?)= 5 computers
July: 2 computers
each computer represents 2000, which should =6k a difference (unless I memorized the problem wrongly).</p>

<p>@annoyingaakash12:</p>

<p>Another way you could solve this problem would be to divide the term # (119) by how many terms are in the set (4 - blue, red, green, yellow). The remainder 3 tells you that you have to look at the third term in the set, which is green.</p>

<p>can we have a consolidated list please? thanks!</p>

<p>@Krem: Jets is referring to the N(x) = -2x + 30 question, and the comparison of units sold in August and July.</p>

<p>the value of the right cylindrical thing with the same base and same radius equaling 64pi and the answer was 4.</p>

<p>anybody remember the answer to the marching band grid-in question?</p>

<p>what did you guys get for, there are 7 different letters and you choose 4 and they can repeat. it was a fill in.</p>

<p>so no one had had the weird triangle one with sidess 2 & 3? What was the question like for the answer 1080? I forgot if i put 1080.</p>
