Question

If the mean of 4,6,x,9,10,5 is 7 , find the value of x

Answer 1

Hii mate !!!
The no. of terms = 6
So. ..4 + 6 + x + 9 + 10 + 5 / 6 = 7
34 + X = 42
X = 8

Hope this helps you. ..

Answer 2

The value of x is "8".

Step-by-step explanation:

The given observations are:

4, 6, x, 9, 10, 5

Mean = 7

To find,  the value of x = ?

We know that,

Mean = $\dfrac{Sum of observations}{Total number of observations}$

⇒ $\dfrac{4+6+x+9+10+5}{6} =7$

⇒ $\dfrac{34+x}{6} =7$

⇒ $34+x =7\times 6=42$

⇒ $x = 42 -34 = 8$

Hence, the value of x is "8".
