<p>What about this one </p>
<p>When does f(f(x)) = x for all x? I put A, which was -x</p>
<p>yes dandelion</p>
<p>I put that too.</p>
<p>Yup (10 char)</p>
<p>are you kidding me, people want to cancel their scores because they're not 800?</p>
<p>did yall put g(x-1)</p>
<p>yes we did.</p>
<p>So Do most people not finish the test in time?</p>
<p>What was the one with a circle externally tangent to another circle or something find r... i don't remember..</p>
<p>I graphed that problem. I think I got (B), but I don't remember the numbers for that problem.</p>
<p>I got C, 1.7.</p>
<p>Aah, I don't remember anymore. Are you talking about the equation of the circle one?</p>
<p>i got c too 4orce...just guess and check on that...did anyone of you find it easy...? way easier than barrons</p>
<p>I'll let you know when I get my scores back...</p>
<p>I felt the test was a bit harder than CB's practice tests. I haven't seen stat for an entire year, so I had to look twice at the box and whisker plot.</p>
<p>I found it irritating how each page had only two questions. It made the test seem a lot longer.</p>
<p>rounds up .</p>
<p>Subtract the number from 50 and round up, if its .5 or above of course.</p>
<p>Birk, I believe the answer to that was g(x-2)</p>
<p>oh yeah i think that's what i meant. was g defined as g(x)=x+1, so it was supposed to end up being x-1? i don't remember the specifics</p>
<p>I got C, 1.7, too. because find distance between centers, subtract radius of the circle you do know the distance of. and that's the radius of the other circle and yah.</p>
<p>do you guys think i can still pull of 700+
if i skipped 4prob and missed about 4~5prob??</p>
