Find the mean of the following data set.
8, 5, 15, 12, 10

50
10
12.5
14

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
