Identify the class width for the following data if creating a grouped frequency distribution with 6 classes. Show or explain how you calculated your answer.
15, 20, 20, 16, 10, 12, 18, 11, 15, 11, 19, 13, 37, 35, 14, 17, 24, 25, 27, 12, 15, 18, 19, 26

i do not know the answer

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

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
