In a class of p students, the average (arithmetic mean) of the test scores is 70. In another class of n students, the average of the scores for the same test is 92. When the scores of the two classes are combined, the average of the test scores is 86. What is the value of p/n?

The first class had an average of 70. That's 16 points below the average score of 86. Since there are p students in the class, the difference from the average is 16 p. The second class had an average of 92. That's 6 points more than the average of 86. There are n students in this class, so the difference from the average is 6 n. Because these classes average out together — as the problem says, "when the scores of the two classes are combined" — the deficit of points has to be equal to the surplus of points. Therefore, 16 p is equal to 6 n. 16 p = 6 n

p/n = 6/16, or 3/8.

What is the volume of a cone with a height of 6 inches and a diameter of 4 inches?

A. 25.20in3

B. 25.12in3

C. 26in3

D. 25in3

25.12in3                                                             

 The equation for the volume of a cone is V = 3.14 x r2  x h/3. r is the determine by D/2, which is: 4cm / 2 = 2cm, insert the value of r we have: V = 3.14 x 22 x 6 / 3 V = 75.36 / 3 = 25.12 cubic inches
