<p>yes only between so 30<x<34</p>

722

<p>Really? Did it say that in the question? I guess I misread it. Wow I'm really dumb because if it said that, that was a REALLY simple problem.</p>

723

<p>but for the midpoint problem, is there any way to do it without plugging in? a more algebraic method, perhaps?</p>

724

<p>idk. I tried doing algebra but then just realized that plugging in 1 would be much simpler.</p>

725

<p>Was the absolute value problem somewhat similar to this problem? </p>

726

<p>If it was, then the answer would be somewhere along the lines of |x-32|<2 which is probably what I put (because I specifically remembered that topic and that explanation. I didn't really think about the actual problem at hand..probably a bad decision =[).</p>

727

<p>the answer is definitely |x-32|<2 'cause |x-32|<2 -> -2<x-32<2 -=""> 30<x<34 :D</x-32<2></p>

728

<p>Ok good I'm pretty sure that's what I put. YAY I GOT AN 800.</p>

729

<p>Who got a question which had a statement saying:</p>

<p>You must study if you want to get a good grade on the test.</p>

<p>Then it said, which of the following is equivalent to this statement?</p>

730

<p>i believe that was experimental section</p>

<p>but i got as an answer: if you get a bad grade on the test, you must not have studied. </p>

<p>I got something along the lines of that.</p>

731

<p>ohh alright, yea thought that could have been the experiemntal</p>

732

<p>yea everyone had a different number 4 =]</p>

733

<p>Anybody get a Hats question or was that experimental too?</p>

734

<p>hats is real ^</p>

735

<p>the midpoint was simple dude
2^k + 2^k+4 / 2 = n.2^k
just remove 2^k from both sides to get n = (2^4 + 1) / 2</p>

736

<p>2^k + 2^k+4 / 2 = n.2^k
2^k (1 + 2^4) = 2n.2^k
1 + 2^4 = 2n
n = (1+2^4) / 2</p>

737

<p>anyone remember a trapezoid problem (not the one within the overlapping circles, i got that 1) that give you the length of the top and the bottom and asked for the perimeter of the rectangle in the trapezoid? When I did it i kept getting something with a decimal that rounds to 22.</p>

738

<p>it was 2(3+8)= 22 yes, but idk where u got decimals..</p>

739

<p>yay!!! i dont remember but i solved for it algebraically but w/e i got 22.</p>

740

<p>it was a 3 4 5 triangle....</p>
