I actually left that one blank. I thought about in on the ride home though and I'm pretty sure it cant be 3, because f(x) and g(x) must have an even degree so h(x) would too. And the least that h(x)'s degree can be is 4 because f(x) and g(x) must have a degree of at least two. So I think 4 must be the answer. I could be wrong though.

And I also said root(3)/2 for the sphere one.

And I also got a^2 + 1

i was havin trouble w/ the roots. cuz some mite be imaginary...

I think I might've missed out on an easy point on the lady-with-the-clothing-store question. I read it three times and could not figure out what it was saying.

Randwulf

What was the lady in clothing store one? 30% profit?

jonnyboy1017

i know jack! it confused me at first too, but im pretty sure its 30% profit. obviously since she sold them for more than she paid, it had to be a profit. and the only answers with profits were 30% and 60%. say she bought 40 jeans for 10 $ each. therefore, she spent 400 bucks. then, she sold half the jeans (20) for 16 bucks each (because she sold them for 60% more than she paid), 10 jeans for 12 bucks (25% off) and 10 jeans for 8(50% off). so she made 520 bucks. so she got a 30% profit

bacdgk

I got 30%.

1/2 stock at original price
1/4 stock at 25% off(?)
1/4 stock at 50% off(?)

She bought the stock at 60% less than her original price.

These data may be all wrong lol.

Monchichi

Yea, I'm 90% sure it was 30% profit.

Question: If everyone does poorly on the Math 2, does the SAT improve the curve?

Thanks! (b/c i think i bombed it.. lol)

bacdgk

The fire alarm success rate one: Alarm 1 has 92% success rate and Alarm 2 has 96(?)% success rate. Probability of at least one going off is just the probability of the lower one right >_>

And the 8 cars in a race where first and last place is known. Total combinations was 6! ?

yellowismellow

AHHHHH WTJOHIUEOWBFK, I THINK I PUT 30% LOSS!!!

*dies in a hole*
...i fail at life.
i think i skipped 8??

jonnyboy1017

and for the one where it said the point was (-2,-3) and asked for sin, did yall get -3/square root of 13?

Randwulf

Monchichi

The way it has been explained to me is that ETS actually decides on the curve before the test is administered. If that's so, then no.

Unless everyone gets 400 or something, they they'd probably do something, lol

bacdgk

and for the one where it said the point was (-2,-3) and asked for sin, did yall get -3/square root of 13?

Yep.

indianmonster

yep 30%

and the stuuupid population after 25 yrs. was is that 109% thing?

ESSENTIAL

The probability of at least one going off is 1-the probability that neither goes off. So the answer is 1-(.08)(.04)

smarty99

bacdgk...i multipeld the probablities...saw a problem similar in a review book. and i put 6!

yes jonnyboy
