PSAT 2010 Wednesday Math Discussion

<p>which question r u guys talking about. i don’t remember an area trapezoid question, can u refresh my memory. is it the one with two triangles and a rectangle and u have to find area. i don’t remeber one with a trapezolid under curve.</p>

<p>was the answer 25 (the one with the two triangles of 7.5 and the rectangle of 10) a multiple choice question?</p>

<p>warlock i think it was grid in , do u remember the ? i am asking</p>

<p>^yes (10char)</p>

<p>thnx dapotatoman, if that is the case what is 314 talking about in his post 155.</p>

<p>quote/
The second one was an area under the curve that just so happened to be a trapezoid (fnInt(2x+4,x,0,3)). /quote</p>

<p>p.s. how do u quote some1</p>

<p>That is the second problem, the one you are referring to is 25.
I have no idea how to quote…How do you?</p>

<p>I take it that no one made the same mistake i did in the triple venn diagram problem…</p>

<p>dapotatoman , can u explain the second problem , to refresh my memory. do u remember what number it was and the answer choices.</p>

<p>im so scared i made a stupid mistake</p>

<p>i think i got find the area of the rectangle/triangle wrong because i went too fast</p>

<p>I dont even remember it</p>

<p>I could not get second one, just the 25 one</p>

<p>k thnx, but do u remember the problem at all , like what it was about, and was it in the second math or the first math, and whehter it was at the beginning orend</p>

<p>I dont remember where the coordinates were 0,3 and 4,0, and you had to find the area under, where the answer was 21</p>

<p>anyone else not have it?</p>

<p>i did not have it porkperson, is that possible, do u know anyone else who didn’t have it</p>

<p>ok good, im not delusional</p>

<p>is 5/7 choice D?</p>

<p>Wow, I think I aced the math section. 80, here I come, if I didn’t make any stupid mistakes. As far as I can tell and see from the posted answers, I haven’t made a single error yet.
Lol I put 42 for the square root integer question grid-in.</p>

<p>How do you solve the Venn Diagram question?</p>

<p>I’m always stumped by that type of question.</p>

<p>@hohohitsvo</p>

<p>You had to find the number of people in sports and drama so it was the two circles that overlapped for sports and drama. There was an “x” in one of the spots so you had to add up all the other numbers and you would find that there were only 230 students represented on the venn diagram even though the question said 250. So x=20 and then 21 was the other section that crossed sports and drama. So you have 20+21=41.</p>

<p>What was the ? and what were the possible answers for the O.N OM5 one?</p>

<p>What was the answer to the q about the thirty numbers and finding their average…</p>
