Question

the weights of 10 boys of a class ate give below in kilograms find the arithmetic mean of 44 36 39 42 53 41 50 36 43 36​

Answer 1

The arithmetic mean of weight of 10 boys is 42

Solution:

Given the weight of 10 boys are 44 36 39 42 53 41 50 36 43 36​

To find:

Arithmetic mean = ?

Solution:

$\text { Arithmetic mean }=\frac{\text { Sum of all weights }}{\text { Total number of boys }}$

Total number of boys = 10

Sum of all weights = 44 + 36 + 39 + 42 + 53 + 41 + 50 + 36 + 43 + 36

Plugging in values in formula, we get

$\begin{array}{l}{\text { Arithmetic mean }=\frac{44+36+39+42+53+41+50+36+43+36}{10}} \\\\ {\text { Arithmetic mean }=\frac{420}{10}=42}\end{array}$

Hence, the arithmetic mean of weight of 10 boys is 42

Answer 2

Given: The weights of the $10$ boys are $44,36,39,42,53,41,50,36,43\ and\ 36$

To Find: Find the Arithmetic Mean.

Step-by-step explanation:

We know,

Arithmetic Mean$=\frac{(x_{1}+x_{2}+..........+x_{n})}{n}$

                                                                  Where $x_{1},x_{2},......,x_{n}$ are weight of the boys and $n$ is number of the boys.

⇒ Arithmetic Mean$=\frac{(44+36+39+42+53+41+50+36+43+36)}{10}$

                               $=\frac{420}{10}$

                               $=42$ kilograms

So, The Arithmetic Mean is $42$ kilograms.
