May 2010 - Math Level 2

<p>^I don’t know if I did it right, but I just found the mean of the w/h and did h/48 = .25
and got 12…im really hoping thats right…</p>

<p>I think I put 190 something. Can’t quite remember.</p>

<p>The one about the circle asked 5 to the RIGHT and 2 DOWN. I think I put D as the answer. Something like (x-8)^2+(y+3)^2=</p>

<p>normally, what’s the lowest raw score to get an 800?</p>

<p>The average shoulder length ratio was about 0.25 so they wanted to know the height of a guy with 48 shoulder length so 48/.25 = 192</p>

<p>The one about the circle asked 5 to the RIGHT and 2 DOWN. I think I put D as the answer. Something like (x-8)^2+(y+3)^2=</p>

<p>^ Phew I put that as well</p>

<p>ricky no, now that I’ve thought about it, it has to be B, since if it was y+3, it went down from a y+1, and I think they said the Y value went up by 2.
EDIT: y+3 is going down because since the y coordinate is -3, it went down from a -1</p>

<p>This test was a little bit easier than the sparknotes practice tests but a little bit harder than another released exam I took. I looked at the 800 cutoff for each and took the average which was coincidentally the same grading scale that sparknotes listed here…

That’s what I did. However, shouldn’t the ratios change when you convert inches to centimeters?</p>

<p>The original center was (3, -1). So 5 right and 2 down would make the new center (8, -3). Thus the new equation would be (x-8)^2 + (y+3)^2 = whatever the original r^2 value was.</p>

I believe it was 25?</p>

Wait…where the units not the same?</p>

<p>so can anyone confirm that problem with the problem with the prime number cubing thing?
EDIT: lol, I dont even remember what I put anymore for that circle problem…DID I put D?</p>

<p>You sure Krazy? If it’s 2 UP then you are right. I was pretty confident it was 2 DOWN though. I can’t seem to remember</p>

<p>Yes, r^2 was 25.</p>

<p>I thought it was centimeters the whole time? Don’t tell me I got this wrong too…</p>

<p>^
I’m 90% sure it was DOWN.</p>

<p>Edit:</p>

<p>I thought it was centimeters the whole time? Don’t tell me I got this wrong too… </p>

<p>^ Me too. @_@</p>

<p>^it was 2 down. I should have been D.</p>

<p>Nope. It was 2 DOWN, not UP. </p>

<p>And also there was no conversion. It stayed centimeters.</p>

<p>100% sure, because I spent about 3 minutes on that question.</p>

<p>@ Krazy</p>

<p>I plugged in values, but was admittedly pressed for time. I know that choice B divided out to be an integer so I put that, but it’s possible that other choices yielded a smaller integer and would therefore be correct.</p>

<p>EDIT: This is referring to the prime number problem.</p>

<p>^So do you know the answer? (for kamikaze612)</p>

<p>@Photographer: Is that for the prime number cubed problem?</p>
