Find the mean and median of the data set. If necessary, round your answer to the nearest cent. Suppose the average yearly prices for an ounce of gold during a 10-year period are as follows:
$279.27, $271.20, $309.89, $363.54, $409.88, $444.90, $603.62, $695.55, $872.12, $972.51

The mean is-
The median is-

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
