Question

The mean of a set of data is an average value of the data. Suppose has vertices A(16, 8), B(2, 4), and C(–6, 12).

Find the mean of the x-coordinates of the vertices.
a.
8
c.
5
b.
4
d.
10

Answer 1

average is total objects divided by number of objects.

so add all x values... 16+2+(-6) and divide the sum by 3 (3 x values)

so 12/3 = 4

so answer is B
