Answer 2

Answer:

The value of x is 3.

Given:

set of numbers: 9,5,7,x,6

mean = 6

To Find:

Value of x.

Step-by-step explanation:

we know that,

mean = sum of numbers/ total numbers

• Sum of numbers:  

    ⇒ 9 + 5 + 7 + x + 6

    ⇒ 27 + x

• Total numbers = 5

Now,

• mean = $\frac{Sum of numbers}{Total numbers}$

    $6 =\frac{27 + x}{5}\\30 = 27 + x\\30 -27 =x\\3= x$

    x = 3

Hence, value of x is 3.
