<p>Which math was the experimental?</p>
<p>oh i didn't need help on the problem i just wanted to know what it was</p>
<p>i know :) Was just saying</p>
<p>wait i was going through this thread and was confused by somepeople's responses</p>
<p>for the overlapping circles, trapezoid problem</p>
<p>answer was 20 right?</p>
<p>ya 4 + 4 + 4 + 4 + 2 + 2</p>
<p>can someone remind me what was the question with the answer 128 in the grid ins?</p>
<p>Wasn't the sequence 2^(n-1)?</p>
<p>DO anyone you remember the question with the answer n^2?</p>
<p>it was like what is the nth number of the sequence:
2, 4, 8, ...</p>
<p>sequence: 2^n</p>
<h1>2, 4, 8</h1>
<p>2^1, 2^2, 2^3</p>
<p>it said 2 was the FIRST term</p>
<p>Was it n^2 or 2^n? i forgot what i chose... Was n^2 even a choice?!</p>
<p>2^n of course!</p>
<p>spidey do you remmber n^2 as a choice? I chose something like that...Maybe i chose the wrong one? Was n^2 a choice? if not, then i probably picked 2^n .</p>
<p>ya it was there too</p>
<p>can someone please explain the question with the tire pressure and the absolute value?</p>
<p>people are saying the answer was lx-32l<2, but if you put in for example 34, that wouldn't be less than two, correct? it said pressue ranged from 30-34. i put something that was like lx+32l > 2, because that obviously worked for all of them, right?</p>
<p>gah, if anyone remember the question completely or can explain it, that would be awesome.</p>
<p>also, there was an inequality question that had something to do with 1/4<x<3/4, right? if anyone remembers the question, and/or the answers please post/explain. thanks.</p>
<p>as for the absolute value question
the tire pressure had to be between 30 and 34 EXCLUSIVE therefore if u say have 33.999, then ud get 33.999-32=1.999 which is less than 2 and if u have 30.001-32 = -1.9999 whos absolutve walue is 1.9999 then that as well would be less than 2</p>
<p>30<x<34</p>
<p>The answer was | x-32| < 2
because it converts to 2 equations:
x - 32 < 2
and 32-x < 2
which give x < 34 and x > 30 respectively</p>
<p>Spidey what choice was n^2? or 2^n?</p>
<p>Was the pentagon one 22?</p>
<p>The triangles on the sides were 3-4-5, right?</p>
<p>it was A. (2 to the n that is)</p>
