<p>I can say for sure x is the second number in that inequality problem.</p>
<p>the answer for the yellow painted squares venn diagram was U. </p>
<p>and i’m positive the question was y-x, which makes the answer x<0. does everyone agree?</p>
<p>^ i agree…</p>
<p>did we figure out which math was experimental.</p>
<p>does anybody remember if they put choice C for the four circles thing?</p>
<p>and I thought it was x+y < x-y…</p>
<p>small circle… is my exp. faulty?</p>
<p>
</p>
<p>if the radius was 1:</p>
<p>I made a 45-45-90. One corner of triangle was the center of one of big circle, bottom left, another the center of the big circle, top right, with the hypotenuse going from center of bottom left to center top right, going thru the small circle. Then the triangle was finished with a 90 degree angle made by the big circle, bottom right.</p>
<p>Each leg was 2; one leg was half of the bottom right circlei, and the bottom left circ. ( = 2r = 2(1) = 2) The other was half the bottom right circi and the top right circ.</p>
<p>Because each leg was 2, hypotenuse was 2sqrt2. subtract 1 for each of the big circle halves going thru the hyp., you get 2sqrt2- (2) = sqrt 2 = diameter small circle.</p>
<p>so radius is (sqrt 2) over 2.</p>
<p>I’ve restated this and nobody’s corrected me… care to tell me where i went wrong, if at all?</p>
<p>if you look at the picture it looks about half of 1 (~4.14). and sqrt 2 over 2 is about .71 something…</p>
<p>that’s how i got it because i got stuck.. it doesn’t make sense for it to be almost 1.</p>
<p>2sqrt2- (2) does not equal sqrt 2.</p>
<p>2sqrt2- (2) is the diameter, so sqrt(2)-1 is the radius. You lost the -2.</p>
<p>I just realized that. I feel ashamed; i’m not stupid… but hey. ok, that makes 2 i know i got wrong. >_<</p>
<p>I actually did measure the little thing with a piece of the page and was going to guess .414… then i thought i did it right with my faulty 6th grade math. ugh. Don’t you hate things like that.</p>
<p>Can somebody reliable post the answers for the student-produced response stuff? </p>
<p>So far I remember 101 for the fence problem (I put 102) and 80/3 for the last question (I was one off on that too!) The only other stuff I remember was the really easy one about finding a number that fit and another answer was 1.</p>
<p>you can just read the posts</p>
<p>I think it would be easier for someone who’s good at math to quickly put all their answers together than to make everyone sort through 24 pages of answers, some of which are obviously incorrect.</p>
<p>what about the graph question about chinese, italian, mexican food:
I. People chose more than one kind of food
II. Half of the people like Italian
III. All people who like Mexican food also like Chinese..</p>
<p>I thought the answer was I only but that wasn’t the answer choice!!
II doesn’t work because the percentages all add upto more than 150% and people who chose Italian food was only 55%..
III ; not sure..</p>
<p>I. People chose more than one kind of food
II. Half of the people like Italian
III. All people who like Mexican food also like Chinese..</p>
<p>I is true, the percentages add up to more than 100
II was actually “more than half the people like Italian”, and it was true, 55%>50%
III was false</p>
<p>The answer was I & II</p>
<p>Couldn’t II have worked since you can’t really have 150%? It would add up to 100%, and since more than one person chose different foods, well, I thought that Italian could work. I did consider the 150% thing, but I thought that I might have been right with the fact that more than one food could have been chosen by people.</p>
<p>here are some of the student response ones…i forgot 2 of them…

<p>It’s probably been discussed already but for this problem:</p>
<p>(2n+1)(3n-11)</p>
<p>What was the answer? I think I put 3 because it said positive integers. 0 is not considered positive, correct?</p>
<p>WAIT you know for that .75 (MANY ANSWERS ONE!) </p>
<p>DO YOU REMEMBER THE QUESTION FOR THAT??! </p>
<p>I PUT .80</p>
<p>.8 is also a valid answer, that’s what I put.</p>
<p>And yeah, does anyone else remember if the (2n+1)(3n-11) problem specified positive integers?</p>
