Question

If mean of 4, 6, 8, 10, x, 14, 16 is 10 then, the value of x is

Answer 1

Answer:

Value of x = 12

Step-by-step explanation:

Given ,

Total observations => 4,6,8,10,x,14,16

Number of observations => 7

Mean = 10

To find the value of X ➡

mean \: = \: \frac{sum \: of \: observations}{no \: of \: observations}

[ Substitute the values ]

10 = \frac{4 + 6 + 8 + 10 + x + 14 + 16}{7}

10 = \frac{58 + x}{7}

10 \times7 = 58 + x

70 = 58 + x

70 - 58 = x

12 = x

Therefore value of X = 12
