<p>did u guys get like 10 lines that are on the pentagon, two points per line</p>
<p>For the cd collections one where 3/8 was given away, and 7/8 of the remaining CDs were given away, how did you guys get 5/64 CDs remaining? I got 7/64 :(</p>
<p>wait now I’m switching back again to I and II only:</p>
<p>if NC is 0.6, then isn’t the statement #states>=5 FALSE, because five would not satisfy the requirements? so the statement isn’t ALWAYS true, so to say that it MUST be true is false?</p>
<p>another way to think about it: what if III was “you need at least two more states”? doesn’t that on a number line look like, given NC=0.7:
<-------X--------------->
6 5 4 3 2
but really only #states>=6 satisfies, so why is 2-5 included in the answer range?</p>
<p>edit: yeah my number lines go in reverse</p>
<p>@daishi55</p>
<p>It’s really hard to explain things without showing, so let me start over.</p>
<p>The shape given is a triangle, and in the triangle, 2 shapes make it up. One is a quadrilateral, and the other is a smaller triangle.</p>
<p>In the quadrilateral, they give you 2 90 degree angles and a 120 degree angle, and you can figure out that the other angle is 60 degrees. </p>
<p>Now that you got that, the triangle comprised of the quadrilateral and the smaller triangle is a 30-60-90 triangle.</p>
<p>Now, look at the smaller triangle. You know that one side is 15(given), and is across the 30 degree angle that you just figured out. Use your trigonometry, and the Sin(15degrees)=15/hypotenuse = 30</p>
<p>Now, add that 30 with the 60(given) which makes the side opposite of the 60 degree angle of the triangle comprised of the quadrilateral and triangle a length of 90. Now that you got that, you can use trigonometry to find the opposite side of the large triangle(which is what the question was asking for)</p>
<p>You can either use Tan(30degrees) = x/90, or you can use Tan(60degrees) = 90/x,
both will give you the same answer(about 51.9) which is equal to 30sqrt(3)</p>
<p>I doubt CB would give us different values.</p>
<p>@nbachamp: yeah, I got 10 c:</p>
<p>@daishi again</p>
<p>If NC was .6, you would still need AT LEAST 5 states to compromise 4.15 million acres.</p>
<p>The two key words are “at” and “least”. So even if you needed 7 states, you would still need at least 5 states, even though you are going to have 7.</p>
<p>Basically it is saying the least amount of states to possibly make up is 4.15 million acres is 5 states. Any more is fine, but 5 is the least amount.</p>
<p>Did anyone have a problem with a parabola that had one labeled point (-1,4) and there were two constants present? You were supposed the find one of the possible constants, which was k if I remember correctly. </p>
<p>In short, did anyone have this problem because I really struggled on that one section because I ran out of time for whatever reason. I believe that it could (here is to hoping/praying) be an experimental section. Am I right or wrong?</p>
<p>is the section with the questions experimental? “what is the greatest integer that solves the inequality sqrt3x - 2 < 9”</p>
<p>how much does it cost to decorate the box one</p>
<p>and “Set A is all multiples of 2 and set be is all multiples of 3”, how many numbers are shared from 0 to 6000</p>
<p>is it experimental?</p>
<p>@Squikii</p>
<p>He gave 3/8 away at first. Then he gave 7/8 of the amount he had left away.</p>
<p>Assume he had 64 CDs to start.</p>
<p>Giving away 3/8s of his 64 CDs will leave him with 40/64 CDs remaining. Then if he gives 7/8s of the 40 CDs he has remaining away, he would end up with 5/64 of his CDs.</p>
<p>@rameshwar Yep, that would be experimental.</p>
<p>As much as i want the answer to be I and II… i realized III is true as well :S
By experience how do you think the curve will be? can some one tell me what i might get by getting -1?
what about -2?</p>
<p>^rameshwar - that was experimental</p>
<p>@Lolol1 - thanks, makes a lot of sense</p>
<p>@Squikii: here is the expression for what’s left in the collection:</p>
<p>x - (3/8)x - ((x - (3/8)x)*(7/8)) = 5x/64 = 5/64 if x=1=whole
^~^~^^^
initial 1st give away 2nd give away</p>
<p>790 by -1, 760 by -2</p>
<p>Probably isn’t going to be a nice curve, as this was very simple.</p>
<p>I’m saying these scores only by looking at a standard raw point conversion chart. You might have better or worse.</p>
<p>WOW -2 is 740?? that looks to low… if i get -2 and they give me a 740 i’m going to be really ****ed… I thought that if you miss only 1 its still a 800…</p>
<p>Sorry, meant 760 :P.</p>
<p>And that depends on the curve. In Oct or Jan, the CR had it so even if you got -3, you would have an 800. It just depends on that curve.</p>
<p>I know for sure this curve wont be really good because i found this test much easier than the may one…</p>
<p>I got something like 5.6 states needed at the minimum, making 5 not enough, so I put I and II. Where did I go wrong with my calculations?</p>
<p>your calculations are fine; your understanding… not so much. It said at LEAST five states.</p>
<p>Does anyone remember if the 30sqrt3 one was C? I don’t remember if I put that or 30sqrt2. I don’t even know if 30sqrt2 was an option.</p>
<p>30sqrt(3) was the correct answer.</p>
<p>30sqrt(2) was an answer choice, but was not correct.</p>
