please someone tell me the water depth math problem where they started out with a certain depth (a number with a 4 in it) and then asked you to determine the ration of this depth to the depth some number of years later. Answer is 5/6? I forgot the problem and don't know what I put. PLEASE SOMEONE HELP ME!!!! THANKS

@FireLion it was 400 or 450 I think, not sure which. The answer was 5/6, it was asking for the % change in the depth of the lake from the beginning of 200_ to the end of 200_ (don't remember which year it was, but it was the last one in the chart).

@Smarty the bar graph question was really simple haha, it just showed a bar graph with the number of children who received 6, 7, 8, 9, and 10 on a quiz or something, and it asked for the number of children who received >7 or something like that, you just had to add them up and the answer was 6, which was the largest of the answers.

@Smarty/heps1996 - Wait, the parabola one was ridiculously simple wasn't it? Or are we thinking of a different question haha? I remember a question with a parabola and it said the vertex was (-1, -1) and there was another point on the parabola (-3, 3) (not sure if these are the exact numbers, but yeah). It was asking for another possible point on the parabola, that would just be (1,3) since a parabola is symmetric, -3 is 2 units from -1, and 1 is 2 units from -1. (-3,3) & (1,3) would be like symmetric points from the vertex.

I thought it asked for the water depth from the end of 200_ to the beg/end (i forgot) of 200_

FireLion

yeah it asked for the water depth from the end of 200_ to the end of 200_

I think I put the water one in decimal form. .833. Should that be fine?

FireLion

can someone refresh me on the bar graph one w/ answer 5 and the parallel lines one with answer 130? thanks

FireLion

im pretty sure the water depth one was a multiple choice one.....

@ColinVW

Decimals are always acceptable. You were correct.

@FireLion

Look a few pages back for the 130 one. I posted a link to the diagram the way that I remember it being.

FireLion

well can anyone refresh me on these three problems.....

sigh i can't wait till december, why does the PSAT take longer to grade than the SAT??

Well, with the SAT, there are tons of options for when you can take it, so there are less kids taking it each time. However, with the PSAT, the majority of sophomores and juniors in the country take the test all in two days, which is a way greater amount in such a short time.
