Identify an outlier in the data set below, if one exists.
{98, 71, 75, 90, 92, 88, 63, 71, 99, 10, 73, 68, 76, 89, 83}
a. 10
b. 71
c. 99
d. no outlier exists in this data set.

check the picture below.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
