The table represents four brands of chewing gum (A, B, C, and D). Three random samples of 40 subjects each were collected. Subjects were asked to taste each brand of gum and pick their favorite brand. Use the mean deviation to determine which gum has the greatest amount of variation in the population. A)Brand A B)Brand B C)Brand C D)Brand D

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

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
