Question

If sigma fixi is equal to 625 and sigma fi is equal to 25 then value of x is

Answer 1

Answer:

x=25

Step-by-step explanation:

x = fixi/fi ........(formula)

x = 625/25

x = 25

Answer 2

The value of $\overline{X}$ is 25

Step-by-step explanation:

• Given that  sigma fixi is equal to 625 and sigma fi is equal to 25
• It can be written as below

$\sum f_ix_i=625$ and $\sum f_i=25$

To find the value of x :

We know that $Mean=\overline{X}=\frac{\sum f_ix_i}{f_i}$

• Substitute the values of $\sum f_ix_i=625$ and $\sum f_i=25$ in the above mean formula we get
• $\overline{X}=\frac{625}{25}$
• Simplify the terms we have
• $=25$

Therefore $\overline{X}=25$

That is Mean = 25

The value of $\overline{X}$ is 25

Or the value of mean is 25 .
