A company specializing in magazine sales over the phone found that in 2500 calls, 360 resulted in sales and were made by male callers, and 480 resulted in sales and were made by female callers. If the company gets twice as many sales per call with a females voice than with a males, then how many of the 2500 calls were made by females?

I am heavily into quantum theory and quantum mechanics. Has anyone been able to "control" it? In theory i will be creating the answers you give me therefore this would be a psudo sociological experiment. Also, what are your thoughts on experiments regarding the matter i.e. sensory deprivation etc. Thanks and your welcome...a little joke for myself.

Pick the letter that cordspondes with each #.
1) y=2x²
2)x²
3) -1/3x²
_________
consider the shape of a parabola to be a "bowl". If the bowl is face up, then we say the "curve" is concave up. In respect to your equations, the standard form of the equation

y=ax^2 +b

"a" tells you if the curve is concave up or down ( pos or neg)
"b" tells you where it crosses the y axis when x is 0

My problems don't make sense, im given 8 equations and a empty graph that show parabala with out any x or y unit boxes.
Problems:
1) y=2x²
2)x²
3) -1/3x²

#3) is telling my that this parabala will be fat in a negative parabala, but there are like 4 negative parabala that shows the same thing. How do I know which is the right one?, they all look the same.

#1) would be skinny and postive parabala curve. There are 4 other postive parabala, how do I know to pick a right one?

Please, explain/show work.
