A company has 20 employees their average salary is $64,000, and their median salary is $40,000. Which statement is true. All employees have a salary of about $40,000
$64,000
Between 40,000 to 64,000
Half of the employees earn higher than $40,000

The last one, Half of the employees earn higher than $40,000

Step-by-step explanation:

The MEDIAN, or Middle salary is $40,000. That is the numbed that is right between all of the salaries. So since it is in the middle, then half of the people are above it, therefore it is the last one.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
