Question

find arthematic mean of first 10 whole numbers​

Answer 1

Answer:-

The mean of the first 10 whole numbers is 4.5.

Explaination:-

Sum of the first 10 whole numbers= 0+1+2+3+4+5+6+7+8+9=45.

45/10=4.5

Hence, the mean of the first 10 whole numbers is 4.5.

Answer 2

Step-by-step explanation:

Given:-

First 10 whole numbers

To find:-

Find arthematic mean of first 10 whole numbers?

Solution:-

The first 10 whole numbers are 0,1,2,3,4,5,6,7,8,9

The sum of the first 10 whole numbers

= 0+1+2+3+4+5+6+7+8+9

=45

Total numbers = 10

We know that

Arithmetic Mean = Sum of all observations/Number of all observations

=> AM = 45/10

=> AM = 4.5

(Or)

We have 0,1,2,3,4,5,6,7,8,9

First term = 0

Common difference = 1-0 = 1

Number of terms = 10

They are in the AP

Sum of first n terms in an AP

=Sn = (n/2)[2a+(n-1)d]

=> S10 = (10/2)[2×0+(10-1)(1)]

=> S10 = (5)(0+9)

=> S10 = 5(9)

=> S10 = 45

Arithmetic Mean = Sum of all observations/Number of all observations

=> AM = 45/10

=> AM = 4.5

Answer:-

Arithmetic Mean of the given problem is 4.5

Used formulae:-

Arithmetic Mean = Sum of all observations/Number of all observations

Sum of first n terms in an AP=Sn = (n/2)[2a+(n-1)d]
