<p>Can someone explain the box-plot question?</p>
<p>Was the standard deviation 8,10,10,10,12? I didn’t have time to put it in my calc.</p>
<p>The box plot is the end of the box is 25% and 75% so the entire box is 50%. 25% going with the 1st quartile and 75% going with the third. The area in between is always the middle 50% Kind of like the middle 50% of SAT scores.</p>
<p>confirm these:
paint 798
juniors and seniors: 77
In QII sinA=0.3, cosA=-0.98…
The length for the similar triangles is 7.1.</p>
<p>Ricky Matsui:</p>
<p>A10 = -2+i</p>
<p>Therefore:
A11 = -1-2i</p>
<p>Since the sequence repeats itself every 4 numbers (ie. A14 is also -2+1, and so is A18, A22, etc.). 99 matches up w/ A11.</p>
<p>i think it was -2+i can anyone confirm</p>
<p>the counterexample is 15 for sure 15-2=13 15+2=17
13 and 17 are prime but 15 is not prime therefore it is a counterexample</p>
<p>A box plot marks five different figures: the minimum, first quartile, median, third quartile, and maximum. The question was asking for the difference in data between the first (25%) and third quartile (75%).</p>
<p>counterexample one is:
is n is a number and n-2 and n+2 is prime then n is prime.</p>
<p>Standard deviation is 8-10-10-10-12
box plot thing is 50% cause its between first quartile and third quartile, AP stats!</p>
<p>for the solutions to the f(x) and g(x) question, wasn’t it finding the x values and also finding the y values? Two equations, you find one unknown and you can solve for the other, so finding either the x or the y values for the intercepting points will give you an answer. Finding the x intercepts of the graphs won’t get you anything about where the graphs intercept each other…</p>
<p>oh, for the counterexample, I put 15. 13 and 17 are prime but 15 is not. Actually, I skipped this one at first because I kept thinking 15-2 = 12, and 12 isn’t prime so I was freaking out since there wasn’t a correct answer choice xD</p>
<p>can someone verify or dispute my walk through of the complex number sequence…</p>
<p>–Given – tenth term = (-2+i)
– i goes in sequences of four, 10/4 = remainder 2 so 10th term of sequence is 2nd of the inner ‘i’ sequence
–Question asked for 99th term of sequence, 99/4 = 3 remainder, meaning 99th term of sequence is 3rd term of ‘i’ sequence
–As defined in the sequence, the next term is ‘i’ times the previous term,
–Therefore 99th = i*(-2+i) = -2i+i^2 = -2i-1 (since i squared = -1)</p>
<p>Answer bubbled = -1-2i</p>
<p>the f(x) and g(x) question answer is I and III.
The complex numbers is definitely -1-2i.
Now, confirm the cosA and the paint.</p>
<p>Juniors and seniors is order DOES NOT matter, so you use permutations NOT combinations.</p>
<p>u use combinations</p>
<p>wasnt the one with the height of 6 54 something?</p>
<p>the tree one</p>
<p>In QII sinA=0.3, cosA=-0.98…</p>
<p>I did sin-1 then cos of answer I think. Wait, I think I did something before that, was there a picture?</p>
<p>Juniors and Seniors I got a way bigger answer. I think b/c I used combinations. And for the prime # one it was 25 not 15.</p>
<p>question about (a,b) (x,y)
ay=xy…
when (3,4)
u had to find x and y?
i put D as the answer…, is that rite?</p>
<p>I got 54 something for the tree one also</p>
<p>Tree height is 54.
Juniors and Seniors is What? I may be wrong, but I bubbled in 840 on my test. (I know I argued differently)
you could just use sin^2A + cos^2A = 1.</p>

tree answer: 54 something</p>
<p>was it like 12 and 9 for the (3,4) equivalency problem?</p>
<p>The test was easier than I thought it would be, but I ran out of time and ended up leaving the last four blank.</p>
