• July $2,873
• August $4,464
• September $3,721
• October $1,989

The  June month salary is closest to her average monthly salary

The Sophie's average Monthly salary income = 3332.2

Step-by-step explanation:

Explanation:-

Given data Sophie's  monthly earnings below

June $3,614

July $2,873

August $4,464

September $3,721

October $1,989

The mean or expected number

                       = ∑x/n

The Sophie's average Monthly salary income

               =    

               =

             = 3332.2

The  June month salary is closest to her average monthly salary

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
