The ages of five friends are 25, 36, 33, 36 and 30 how many of friends are older than the average (arithmetic mean) age?

1 answer:

4 0

Answer:

3 friends are older than the average.

Step-by-step explanation:

First find the mean. The mean can be found adding all the numbers in the set together and dividing by the amount of numbers in the giving set:

(25 + 36 + 33 + 36 + 30)/5 = (160)/5 = 32

The average age is 32. There are 3 friends that are older than the average (33 , 36 , 36, respectfully).

$\sf\dfrac{2k-10}{-7}=8$

Multiply -7 to both sides:

$\sf2k-10=-56$

Add 10 to both sides:

$\sf2k=-46$

Divide 2 to both sides:

$\sf~k=-23$
