<p>@IMauriuolo: that was not experimental; answer was 6.</p>
<p>I don’t remember the scissors question. Is that the one we count 20 scissors, each represents 400 something, then they ask the total one?</p>
<p>yep 10char</p>
<p>Oh yeah! the answer with 27/8 (3.375), could i have put 3.38?</p>
<p>oh so why is it 1600/ i thought 20x400= 8000?</p>
<p>no it was the average, so you add up the number of scissors and divide by the number of days (i think 5) then multiply by 400.</p>
<p>can anyone answer my question? x^2=81 y^2=16 find k when x^2-y^2=(something)/k</p>
<p>yeah is 3.38 an acceptable answer for 27/8?</p>
<p>@yoman91: answer was 12</p>
<p>WAIT</p>
<p>(x^2-y^2)=(x-y)k or /k ??</p>
<p>My bad, I thought you were talking about the other question with k. That one should be 13?</p>
<p>Yes I got 13 too but yoman scared me by saying it was divided by k and not multiplied</p>
<p>So far im -1</p>
<p>because on that rectangle square cutout problem I forgot to square my hyp and subtracted 5 and not 50</p>
<p>should have realized that my answer made no physical sense haha</p>
<p>it’s okay i’m -1 also because I didn’t get the slope = 0 one haha <em>facepalm</em></p>
<p>so what is the estimate score for a -1 or 2?</p>
<p>760 - 790 I’d guess.</p>
<p>I’m -1 as of now too. I messed up the “directly proportional” problem with the (y-1) (x+1). I put 10 instead of 9… haha stupid mistake.</p>
<p>Do you guys think -1 will still be a 790? I’m really hoping it’s not a particularly brutal curve…</p>
<p>was the directly proportional a fill in?</p>
<p>Yeah, it was the last grid-in question.</p>
<p>what was the question?</p>
<p>does anyone remember any other grid-in questions…i feel like i had to rush to get them finished…</p>
