In a small company of 10 people the salaries are as follows: 5 people earn $25,000, 3 earn $27,000, 1 earns $34,000, and the owner earns $60,000 what is the mean and standard deviation (to the nearest dollar) of their salaries?

mean salary: $

standard deviation: $

The mean is 30000 and standard deviation is 9746.79.

Step-by-step explanation:

Formula of mean

Formula of standard deviation:

Using the below table.

Therefore the mean is 30000 and standard deviation is 9746.79.

the solution is h=10 because you add 9 to each side of the equation.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
