The approximate z-score that corresponds to a right tail area of 0.42 is what?

A right tail area of 0.42 means that we are looking at the area covered by 1- 0.42 = 0.58 from the left. From the standard probability distribution table, we located what is Z score at P = 0.58, hence the answer is:

Z score = 0.202

.25

step-by-step explanation:

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
