Aparticular brand of dishwasher soap is sold in three sizes: 25 oz, 45 oz, and 60 oz. twenty percent of all purchasers select a 25-oz box, 50% select a 45-oz box, and the remaining 30% choose a 60-oz box. let x1 and x2 denote the package sizes selected by two independently selected purchasers. (a) determine the sampling distribution of x. x 25 35 45 42.5 52.5 60 p(x) calculate e(x). e(x) = oz compare e(x) to μ. e(x) > μ e(x) < μ e(x) = μ

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
