5) the mean salary of 5 employees is $40300. the median is $38500. the lowest paid employee's salary is $32000. if the lowest paid employee gets a $3100 raise, then a) what is the new mean? new mean = $ b) what is the new median? new median = $

New mean = $40920

New Median = $38500 (Same as old)

Step-by-step explanation:

Given

Mean = $40300

Median = $38500

The formula for mean is:

Mean = Sum/No. of Values

According to the formula,

40300 = Sum/5

40300*5 = Sum

Sum of Salaries = 201500

If the salary of lowest employee is raised 3100, then sum will be 204600.

The new mean will be:

Mean = 204600/5

Mean =$40920

The median will remain unchanged as it is the middle value of 5 quantities. 2 values are greater than median and two are less than median. Even after the raise in salary, the salary becomes $35100 which is still less than median. So the median will be same as old ..

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)
