Question

if the mean of 16, 14, X, 23, 30, is 18, find the value of X ​

Answer 1

Answer:

x = 17

Step-by-step explanation:

Total no. of observations = 5

Arithmetic mean = Sum of observations/Total no. of observations

18 = 16 + 14 + x + 23 + 30/5

90 = 73 + x

x = 90 - 73

x = 17

Answer 2

Answer:

answer

Step-by-step explanation:

$mean = \frac{sum \: of \: observations \: }{total \: observations} \\ 18 = \frac{16 + 14 + x + 23 + 30}{5} \\ 18 = \frac{73 + x}{5} \\ 18 \times 5 = 73 + x \\ 90 = 73 + x \\ 90 - 73 = x \\ 17 = x \\ \frac{ - - } {}$
