Question

if the meanof 3,1,5,x and 9 is 4 then find the value of x ​

Answer 1

Answer: The value of x ​is 2

Step-by-step explanation:

Given, arithmetic mean =4

Arithmetic mean=sum/number

Arithmetic mean=3+1+5+x+9/5

4=18+x/5

x=20-18

x=2

Thus we get the solution the value of x ​is 2

Let us check put x=2

=3+1+5+2+9/5

=20/5

=4

Here we get the arithmetic mean is 4
