Math Question Compilation for June 2008 SAT

<p>for the population one with 21 and older i got 5040 is that right</p>

<p>I don't remember that question gryffon.</p>

<p>P = 15 - 2r</p>

<p>avg = 8</p>

<p>don't forget than r can be 0(zero)</p>

<p>so 15+13+11+9+7+5+3+1 / 8</p>

<p>= 8</p>

<p>p=13+11+9+7+5+3+1=49
49/7=7 right answer</p>

<p>you'llsee wasn't it positive integer? Is zero a positive integer, I have a brain faat.</p>

<p>Ah, right, positive integers.</p>

<p>WOOT! I put 7~!!!!</p>

<p>it was 2000, tommy91.</p>

<p>Didn't it say that R was a positive integer?</p>

<p>could r not equal 0?</p>

<p>if it can't then I am wrong...but i don't see why it can't be zero.</p>

<p>isn't 0 a positive interger?</p>

<p>I don't remember 2000 at all, but I remember the number 5040? I think? Ugh I don't remember but if I missed that question I'm going to scream. D:</p>

<p>0 is not a positive interger.</p>

<p>lol...can zero be a pos. integer?</p>

<p>yikes!</p>

<p>I remember something confusing on the population one. I think I had 5040 before I realized you had to deduct some more for the people who were over 21 but also over 40 or whatever,</p>

<p>popluation:8000
Above 21:63%
8000x(.63)=5040 </p>

<p>Thats what I put</p>

<p>yea i thkn we did elanorci i thikn we 4got to substract the pecents b4 multiplication shiit well i think i only got 5 wrong 1 of em being a grid in nyone have any ideas what that might e hopefuly a 700+!?!?!?</p>

<p>taz, the question said find the population that is over 21, BUT under 40.</p>

<p>it was like population of people above 21 and lower than 40...</p>

<p>how do you find it?</p>

<p>i know this is probably an easy question lol, but what did you guys put for the 540 pg book with 50 lines changing it to 54 lines per page?</p>

<p>yea i remember getting 5040 and then subtracting something from it</p>

<p>i know this is probably an easy question lol, but what did you guys put for the 540 pg book with 50 lines changing it to 54 lines per page?
