<p>shoot, i thought it was “1/n minus 1/p, 1<n<3, 2<p<4” or something like that</p>
<p>i thought the avg question’s answer was 1.25… wasn’t it (1/1+1/2)/2 = 1.25 the greatest value…?</p>
<p>No, .75 </p>
<p>It was the average of 1/2 and 1/1.</p>
<p>Man, I did the same thing AznPwyd! =(</p>
<p>(1/1+1/2)/2
=(3/2)/2
=1.5/2
=.75</p>
<p>holy… complete mental error</p>
<p>question…on the Psat, do the questions go in order of difficulty like the SAT?? i hope not</p>
<p>Yeah, they supposedly do</p>
<p>also…was it the same test as taken on WEdnesday?</p>
<p>no, i wish if it was the same</p>
<p>I don’t think so…I’m sure the CB knew if they had the same test that people would talk about it between Wednesday and Saturday</p>
<p>Ok why is the answer to the triangle 18? The question said B(-3,2) and D(3, -4) were opposite vertices. So you have a square with a diagonal of 6 which is the distance between B and D. The square has two 45,45,90 triangles with a common hypotenuse BD which is 6. That means the sides of the square are 3 x root 2. the area of the square is (3 root 2) squared =18. H is between BC so you have a triangle with a base of (3 root 2) and a height (3 root 2). (3root2) times (3 root 2) is 18… divide that by 2 is 9</p>
<p>Question about the last grid in.</p>
<p>I got zero, but there was no zero in the first column to grid in. I wrote zero in the box above it though. Will I still get points?</p>
<p>Can someone tell me why they thought the sides of the square was six for that math question grid in?</p>
<p>I’m not totally sure about that triangle problem any more, with all this controversy, but [here</a> is how I understood the problem](<a href=“http://ameri-cantraders.com/math.jpg]here”>http://ameri-cantraders.com/math.jpg).</p>

<p>Correction: I’m not going to edit my picture, but by “midpoint of B and C,” I meant, “midpoint of line BC.”</p>
<p>Thank you, differentiable…that’s how I saw it too.</p>
<p>Lakers08: How is the distance between (-3,2) and (3, -4) equal to 6?</p>
<p>Damnit… i did the distance equation wrong… ok i see the picture now. What do you guys think minus 7 to 9 on CR will be (with no omits)</p>
<p>Ok, the cake/pizza/salad question completely stumped me…could someone please set up the equations?</p>
