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?
2 answers:
Answer:
10
Step-by-step 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.
Answer:
median: 10
Step-by-step 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
