If x = 4, you would replace the “x”s with 4’s! So the problem would work out to be 4^2 - 4 over 4 - 8. 4^2 = 16. You would then subtract. 16 - 4 = 12. Now your problem is 12 over 4 - 8. 4 - 8 = -4. Now your problem is 12 over -4. So now you just divide. 12 / -4 = -3! -3 should be your answer! If you need me to write it out to show you I’d be happy to! Hope this helps! :)

$n \geq -\frac{-29}{28}$

Step-by-step explanation:

Mean: $620, Mode: $600

Let's sort the rank stats.

First quartile: $580

Median: $610

Third quartile: $645

85th percentile: $685

OK, we're ready. What happened to a and b?

c. $645 is the third quartile, 75th percentile. That means 25% of the salaries are higher.

Answer: 25%

d. $685 is the 85th percentile, 15% greater.

Answer: 15%

e. The mean is the sum of all the salaries divided by the count.

Mean = Sum / Count

So the sum is the count times the mean,

Sum = Count × Mean = 100 × $620 = $62,000

Big payroll.

Answer: $62,000
