Question

mean of a data is 5,9 ,x ,10,16 is 12 then find the value of x​

Answer 1

Answer:

$20$

Step-by-step explanation:

$mean = \frac{sum \: of \: all \: observation}{total \: number \: of \: obervations}$

$mean = 12$

$\frac{5 + 9 + x + 10 + 16}{5} = 12$

$\frac{40 + x}{5} = 12$

$40 + x= 60$

$x = 60 - 40$

$\boxed{x = 20}$

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

Mean = Sum of observation/no of observation

12 = (5+9+x+10+16)/5

12×5 = 40 + x

60 = 40 + x

60 - 40 = x

20 = x

So, value of x = 20
