<p>permutations - order DOES matter
combinations - order does NOT matter</p>
<p>juniors and seniors you had to nCr the juniors then the seniors then multiply the values. It was 850 (or something like that)</p>
<p>So we use combinations and get 840?</p>
<p>yes i got sumthing liek that kiruyama</p>
<p>it was -1-2i</p>
<p>my easy way:</p>
<p>10th: -2+i
11th: i(-2 + i)) = (-2i + i^2)
12th: i(-2i + i^2) = (-2i^2 + i^3)
99th: i(-2i^88 + i^89)=(-2i^89 + i^90)</p>
<p>stick dat in mah calculator, ba da bing ba da bang, jizzed in mah pants</p>
<p>I put the largest one for juniors and seniors, which I don’t remember now. I actually don’t remember most.</p>
<p>Can anyone give me a ballpark of what kind of score to expect with 8 omits and 2-3 wrong?</p>
<p>PAINT CONFIRMATION:</p>
<p>rectangular container with (L,W,H) (18,15,8) …everything painted EXCEPT FLOOR</p>
<p>therefore, it is </p>
<p>ONE<em>(18</em>15) + 2<em>(15</em>8)+2<em>(18</em>8) = 798</p>
<p>row triangle: 201
exp regression: 24
x^2-y^2=72: -12
f(g(x))=x: 1/x
reflection problem: -f(-x)
f(x+3): e^x
pentagon prism: 15 edges
movie q: n= x/(.6d)
boxplot: 50%
counterexample: 15
complex numbers: -1-2i
tree answer: 54 something
paint: 798</p>
<p>what was the answer for the probability of sum of 2 number that is greater than 100?
1,5,10,100…
i was getting 1/4=.25
so i omitted it</p>
<p>I got .33 10char</p>
<p>What were our opinions on the overall difficulty of this test? I thought it was moderate after using barrons to prep.</p>
<p>nd for the tree one…
we had to add 6 after we get the number by using sin formular… rite?</p>
<p>I got a half, 6 possible 101,105,110, 6,15,11 3 are over 100</p>
<p>Confirms
similar triangles:
Ratio of side lengths is 3:2 angle is 42 degrees. Should work out to 7.04, closest answer is 7.1</p>
<p>The graph with g(x) above f(x) is g(x)-f(x)>0</p>
<p>juniors and seniors:
(6C2)(8C3)=840</p>
<p>Well for the tree one you could just use the ratio of tan…
the 1,5,10,100 thingy was 50% chance.</p>
<p>I got .50</p>
<p>1, 5, 10, 100</p>
<p>1 + 5
1 + 10
1 + 100
5 + 10
5 + 100
10 + 100</p>
<p>6 possibilities, 3 are over 100? That’s how I reasoned it anyway… I’m not exactly a math expert so feel free to rip that solution apart.</p>
<p>I still thought it wasn’t that easy after using Barron’s (although, I never finished Barron’s b/c it ****ed me off)</p>
<p>Whoa, I didn’t know CC did that. I didn’t use the F word for the record ^</p>
<p>Yeah, .5 makes sense, I put different order but I guess that doesn’t matter.</p>
<p>People who are experienced with the curves… 8 omits 3 wrong = ??</p>
<p>i got .5, 10char</p>
<p>@shizzle, you put the urinate word right? the f-word made no sense there.</p>
