The salaries of the employees at four companies are summarized below. Answer the questions about them. Company A: The mean salary is and the range of salaries is .
Company B: The mean salary is and the range of salaries is .
Company C: The mean salary is and the range of salaries is .
Company D: The mean salary is and the range of salaries is .

(a) Based on the information above, which company's salaries have the most variability?

Company A

Company B

Company C

Company D
(b) Based on the information above, which company has the lowest salaries on average?

Company A

Company B

Company C

Company D

(a) Company A

(b) Company D

Step-by-step explanation:

The range is the variability measurement.

a. The companies salaries have the most variability i.e. highest range. As it can be seen that the highest range is of Company A i.e. 59,000 so the same is to be considered

b. The lowest salaries on an average i.e. lowest mean is of company D i.e. 35,000 so the same is to be considered

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
