Answer 2

Answer:

The arithmetic mean of all even numbers between 89 and 101 is 95.

Step-by-step explanation:

Given : Numbers between 89 and 101

To find : The arithmetic mean of all even numbers between 89 and 101?

Solution :

First we find the even numbers between 89 and 101.

Numbers are 90,92,94,96,98,100

Arithmetic mean is the sum of all the numbers divided by total numbers.

$AM=\frac{\sum x_i}{n}$

$AM=\frac{90+92+94+96+98+100}{6}$

$AM=\frac{570}{6}$

$AM=95$

Therefore, The arithmetic mean of all even numbers between 89 and 101 is 95.
