Question

Find the mean
· If the mean of 16, 14, x, 23, 20 is 18, find the value of x.
find x.​

Answer 1

Answer:

mean = (16+14+x+23+20) ÷ 5

18 = (73+x) ÷ 5

18x5 = 73 + x

90 = 73 + x

x = 90-73

x= 17

Answer 2

Answer:

17

Step-by-step explanation:

Mean of a data is given by:-

Sum of observations/ Number of observations.

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

=> 73 + x/ 5 = 18

=> 73 + x = 18(5)

=> 73 + x = 90

=> x = 90-73

=> x = 17
