SAT May 2009 Math

<p>^ maybe like a 710 - 730?</p>

<p>Somebody post past curves; those are always floating around here somewhere.</p>

<p>^ Yea that question took me some time to figure out.</p>

<p>It went something like person A B and C are taking different tests (physics p, calculus c, and English e) on different days (Monday M, Wednesday W, and Friday F). Person A is taking her test after someone who takes P and before person B. Person B is not taking p. What day and test is person A taking.</p>

<p>The calculus on Wednesday was like this:</p>

<p>So, three people have to write reports on Calc, English and physics. The guy doesn’t take Calc and the girl has to write her report before the guy’s physics report or something. </p>

<p>My reasoning was that it couldn’t be anything on a Wednesday. I don’t know how you guys got Calculus on a Wednesday…</p>

<p>Also, could someone explain the triangle one where the answer was 3pi?</p>

<p>I remember that in my booklet i drew a little chart and for person C i put he was taking physics the first day, and A calculus the next, and B English the last. but for some reason i remember picking a choice with “physics” in it!! Hopefully i’m just being paranoid and picked calculus wednesday. i think i remember putting answer choice D. was D “calc wednesday”?</p>

<p>Darn it Gaoez…you beat me to it.

<p>D was physics tues, that’s what i put but it’s wrong…</p>

<p>Billy, the calculus answers were the first two choices - A & B. So D couldn’t have been Calc on Wednesday. I remember crossing all the Calculus answers out…</p>

<p>Haha.
/fail</p>

<p>miss_murd3r: you had to find the circumfrence of the imaginary circle and divide by two since there were three 60 degree circles (60*3 is 180, which is half of 360).</p>

<p>aw! ef you see kay!!! well then i definitely missed 2 mc and the one grid in.</p>

<p>^ What score range would tha be?</p>

<p>^ yea the triangle one with 3pi</p>

<p>It said that there was an equilateral triangle, with some weird shape that cut the side of the triangle in half, where each side was 6. then it said that the vertices of the triangle were the center of circles. So, since you know that the angle are 60 (b/c of equilateral triangle) then you find the circumference of the circle with radius 3, and then multiply by 60/360 or 1/6. That give you the length of one side of the weird shape (pi), so multiply by three cuz it has three sides. So you get 3pi.</p>

<p>idk… i was hoping someone would tell me it’s above 750! lol</p>

<p>It is above 750.</p>

<p>@dillbilly: Noooo idea what you just said there. So, with the shaded figure inside the triangle, you make an imaginary circle? All I remember in that problem was that they give you the side of the triangle - it was 6. </p>

<p>@Skyhigh: I’m guessing around 740ish…depending on the curve.</p>

<p>^ You are joking right? This test is easy, at home I can probably get them all right but I screwed up big time during the real test. I can get 800 constantly for practice tests…</p>

<p>Ohhhhh!!! Thanks. I didn’t realize that. I had like 30 seconds to solve that one before time was called.</p>

<p>That makes sense. Thanks Gaoez!</p>

<p>@ miss_murd3r: sorry… Gaoez explains it with much more detail… :|</p>

<p>dillbilly - thanks for attempting to explain it to me. Haha.</p>

<p>What do you guys think was the hardest problem on the test?</p>

<p>For me…it had to be the first math problem. I was so flustered. Took me AT LEAST 10 minutes to solve it. I broke my pencil.

<p>Haha. Kidding. I hate how these problems are so easy; they’re just phrased to make it seem hard. I end up overthinking everything. Calculus problems can sometimes be easier than these stupid SAT ones…</p>

<p>What was the solution to the following question?
There are two departments A and B. In department A 50% of the workers are female, while in department B 60% of the worker are female. If two workers, 1 from each department, are selected randomly, what is the probability that at least one of them is a female?</p>
