Question

the value of os the mean of 16, 14, X, 23, 20 is 18 find the value of x
​

Answer 1

Answer:

x = 17

Step-by-step explanation:

Given,

Values = 16, 14, x, 23, 20

Number of values = 5

Mean = 18

To find,

Value of x

Procedure,

$\frac{16 + 14 + x + 23 + 20}{5} = 18$

$\frac{16 + 14 + 23 + 20 + x}{5} = 18$

$\frac{73 + x}{5} = 18$

$73 + x = 18 \times 5$

$73 + x = 90$

$x = 90 - 73$

$x = 17$

Therefore, the value of x is 17

Answer 2

Answer:

x = 17

Step-by-step explanation:

For finding x,

Mean = sum of all observations / number of observations

18 = 16 + 14 + x + 23 + 20 / 5

18 X 5 = 16 + 14 + x + 23 +20

90 = 73 + x

x = 90 - 73

x = 17
