(100 points) This is 100 points. It's hard, so please take question seriously. Compare and contrast those sounds to the frequency of your tone. What conclusions can you make about frequency?

Write each frequency in the equation:

Frequency = 1 / period

How long does my answer have to be?

Step-by-step explanation:

Frequency Polygon • The frequency polygon of a grouped frequency distribution is constructed by joining by means of straight lines the points whose abscissas are the mid- points of the classes and the ordinates are the corresponding frequencies.

Step-by-step explanation:

No need to apologize, that's why we're here.

Rectangular prism, 25x10x8

The surface area is the sum of the area of all the surfaces.  We have 2 surfaces that are 25x10, two 25x8 and 2 10x8 so our total surface area is

2(25(10) + 25(8) + 10(8))=2(250+200+80)=2(530)=1060, choice B

Red marble, 15 out of 40, 15/40 = 3/8, choice B again

There's really not enough information to answer unless we assume the only ways Bart washes his car is the gas station or himself.  Assuming that, the probability he washes it himself is 1 minus the probability he washes at the gas station.
