<p>well it depends on the colleges you wanna apply to…but i wouldnt cancel unless you did really badly</p>
<p>For roots s+1 and t+1: x^2-9x+10 = 0. (B)
Stone - 1 sec. after reaching max. (B)</p>
<p>f^-1 (2e) = .34</p>
<p>If this was on Level 2 (I am not sure): in 50 years 15,000(1.08)^x - the greatest. (E).</p>
<p>Some people asked about x/(2y-x) = 10.
One way to solve: let x=20, then y=11; plug’em in.
11/29. (D)</p>
<p>uuuh @gcf101 i rememeber the first two questions but i don’t rememebr the one about 15,000 (1.08)^x.</p>
<p>My bad - must be from Level 1.</p>
<p>haha that’s fine but i’m pretty sure the first two were right. i don’t exactly remember the 0.32 one but if it was just a inverse plug-in problem hopefully i got it right</p>
<p>What do you guys think the curve will be like for this test?</p>
<p>Wouldn’t the stone one be 2.5sec because the question said “after it reaches the highest point”?</p>
<p>And…if you omitted 2 and got around 3 or 4 questions wrong, would you still be able to get an 800?</p>
<p>The stone reaches the highest point at 1.5 sec.
2.5-1.5=1</p>
<p>The question gave you a specific height though…and you were supposed to find how many seconds it took for the stone to reach that height after it reaches the max</p>
<p>To gcf101: do you still remember if the absolute value question with the maximum value of k=1/3 was answer choice B? Or was it C? I can’t remember… Thanks!</p>
<p>This would be the answer if the problem said without replacement…but it didn’t.</p>
<p>The chance you have an even number is 4/9 the first time and it is also 4/9 the second.
If you prefer combinatorics you can do it this way:
nCr(4,1)/nCr(9,1) and then you would multiply the two by each other, for the chance is the same regardless of the trial…</p>
<p>I could be wrong though.</p>
<p>PS: I was talking about the one with the set of numbers… (1,2, …9)</p>
<p>Missed 1 that I know of and omitted 3, what would that score be? Chances are I missed more.</p>
<p>^^Not to be rude, but you are definitely wrong. The answer to that question has been established as 1/6.</p>
<p>^You’re at 800. You can have up to a -6 raw score and still have a perfect score.</p>
<p>I’m quite sure its 1/6.</p>
<p>I have been looking at the responses and I feel like I have benefited greatly from them.
Also the question about the set of numbers (1,2, …9) should just be 4/9*4/9. The test never made it clear whether it was with or without replacement, and I just assumed that it was with replacement.
I am going to be really angry if I get that question wrong.</p>
<p>uum i think it was a trick question to see if you could remember from the other probability questions that you’re supposed to do 4/9 * 3/8 and not 4/9 * 4/9. that’s just my opinion but whatever</p>
<p>About the stone one, I feel that I misinterpreted the question because I believe it said “When is the stone’s height 20ft after it reaches maximum height?” This led me to think that they were saying “find the x coordinate for which the y coordinate is 20 to the right of the maximum.” Can anyone verify whether this is correct or not?</p>
<p>naww it’s incorrect because they asked how much time it would take AFTER the stone reached the top (1.5 seconds) to reach 20m. if you used the quadratic formula it gives you 0.5 and 2.5, and since you know that 0.5 is the time when the stone first reaches 20m BEFORE it reaches the top, you know that you have to use 2.5 as the second time it reaches 20m. so therefore 2.5 - 1.5 is 1.</p>
<p>Ah, I thought they were asking at what time the stone reached 20m after it reached its maximum height. Silly me. :D</p>
