Class width is found by choose the correct answer below. a. subtracting a lower class limit from the next consecutive lower class limit b. subtracting the lower limit of one class from the upper limit of that same class c. subtracting the smallest value in the data set from the largest value in the data set d. adding the lower class limit to the upper class limit and dividing by two

a. subtracting a lower class limit from the next consecutive lower class limit

Step-by-step explanation:

Class width is found by - subtracting a lower class limit from the next consecutive lower class limit .

Class width is defined as the difference between the upper or lower class limits of consecutive classes.

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
