Answer:
=9.4
Step-by-step explanation:
The median is the middle of the numbers when lined up from smallest to largest
(n, n+5, n+6, n+9, n+15)
The median is n+6
n+6 = 9
Subtract 6 from each side
n +6-6 = 9-6
n = 3
The numbers are
(n, n+5, n+6, n+9, n+15)
3, 8 ,9 ,12, 15
The mean is where you add up all the numbers and divide by the number of numbers
mean = (3+8+9+12+15) /5
= (47)/5
= 9 2/5
=9.4
