Question

PERSON GETS 15 POINTZ PLZ HURRY The mean of the list n, n + 3, n+4, n+5, n+6, n+8, n+10, n + 12, n+15 is 11. What is the median?

Answer 1

median: 10

Explanation:

There are 9n, and the numbers add up to 63, and there are a total of 9 terms.

The equation is (9n+63)/9=11.

(9n+63)/9=11

9n+63=99

9n=36

n=4

To find the median, eliminate the terms

The middle term is n+6

n+6

4+6

10

So the median is 10

Answer 2

10

Explanation:

To find the value of n we can write:

(n + n + 3 + n + 4 + n + 5 + n + 6 + n + 8 + n + 10 + n + 12 + n + 15) / 9 = 11

(9n + 63) / 9 = 11

9n + 63 = 99

9n = 36

n = 4

The median is n + 6 which is 4 + 6 = 10.
