Question

Find the mean of first 10 even natural no.

Answer 1

MEAN = Sum of all observations/No of observations
     Observations:2.4.6.8.10.12.14.16.18.20
= 2+4+6+8+10+12+14+16+18+20/10
= 110/10
= 11
.

Answer 2

Answer:

The mean of first 10 even natural no. is 11.

Step-by-step explanation:

To Find :Find the mean of first 10 even natural no.

Solution:

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

$Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}$

$Mean = \frac{2+4+6+8+10+12+14+16+18+20}{10}$

$Mean = 11$

Hence the mean of first 10 even natural no. is 11.
