<p>great, got that wrong too. ugh</p>
<p>Can someone post all answers discussed?</p>
<p>^^ yea my bad, 8,10,10,10, 12
that one chocie D</p>
<p>Standard deviation didn’t require any real math on this test. You just eyeball it and see which has the least variation, they make it obvious if you know what SD means.</p>
<p>I got D (8,10,10,10,12) for the Standard Dev question also.</p>
<p>What did you get for that one function that was weird and it asked you what function would make the new graph.
answers were like:
y = f(-x)
y = -f(x)
y = -f(-x)
y = -f(-|x|)</p>
<p>etc.</p>
<p>did any1 get -2-2i for the last q?
@ k200 i got -f(-x)</p>
<p>hey, what did you all get for the probablity one for forming a group of seniors and juniors?</p>
<p>I know it was like the easiest question, but what was the answer to the prism one? It made me think 
got 15.</p>
<p>i got 15 as well
at mnky: isnt it 20%?</p>
<p>wasn’t the one about the commitee of seniors and juniors combinations and not probability? maybe I’m just not remembering it right…
and I got -f(-x) for the graph too</p>
<p>and I got 15 for the prism edges too</p>
<p>I got -F(x) but it was a guess. The Seniors and juniors was pretty easy - find all the combinations for the seniors and multiple by all the combinations for the juniors.</p>
<p>I’m pretty sure -f(-x) is correct.</p>
<p>I also got 15 for the edges.</p>
<p>And what was the answer to the Seniors and Juniors one?</p>
<p>same as those answers ^^^</p>
<p>can any1 confirm the box plot thingy was 20%?</p>
<p>yeah for the seniors/juniors it was something like 56 x umm something.</p>
<p>Something in the 800s, yeah</p>
<p>for seniors and juniors, was the answer in the 800s?</p>
<p>yes 840 i beleive</p>
<p>^^^^ Yeah I think so…</p>
<p>I think it was 820 - but I’m not positive.</p>
<p>^ Yea, it was</p>
