Question

find mean of first 10 even natural number

Answer 1

 first 10 even natural numbers are 2,4,6,8,10,12,14,16,18,20

so mean = 2+4+6+8+10+12+14+16+18+20/10 = 110/10 = 11

Answer 2

Answer:

 Mean = 9

Explanation:

As per the question,

First 10 even natural number are given as:

0, 2, 4, 6, 8, 10, 12, 14, 16, 18

Now,

Mean is define as the ratio of the sum of total frequency to the total no of frequency.

$Mean=\frac{Sum\ of\ Frequency}{Number\ of\ frequency}$

$Mean=\frac{0 + 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18}{10}$

$Mean=\frac{90}{10}$

Mean = 9

Hence, The required mean = 9
