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.

Step-by-step explanation:
Answer:
a = 8.
Step-by-step explanation:
a/4 + 8 = 10 where x is the number to find.
a/ 4 = 10-8 = 2
a = 4*2
a = 8.
X=5/8 or x=-4/3
here is the work if needed...
24x^2+17x-20=0
Step one: Factor left side of equation.
(8x-5)(3x-4)=0
Step two: Set factor equal to 0.
8x-5=0 or 3x-4=0
x=5/8 or x=-4/3
