Answer 1

Mean = E fixi / n

41.6 = 1248 / n

n = 1248 / 41.6

n = 30

Answer 2

The value of n is 30.

Step-by-step explanation:

Given : The value of mean is 41.6 and $\sum x_if_i = 1248$.

To find : What is the value of n​ ?

Solution :

The mean formula is given by,

$\text{Mean}=\frac{\sum x_if_i}{n}$

We have given,

Mean is 41.6.

$\sum x_if_i = 1248$

Substitute in the formula,

$41.6=\frac{1248}{n}$

$n=\frac{1248}{41.6}$

$n=30$

Therefore, the value of n is 30.
