Answer:

sum of the no.s =10+14 +18+x=42+x

mean=(42+x)/4=16.2

              42+x=16.2*4

                        x=64.8-42

                         = 22.8

Answer 2

Answer:

22.8

Step-by-step explanation:

mean = sum of observations ÷ no.of observations

16.2 = ( 10 + 14 + 18 + x) ÷ 4

64.8 = 42 + x

64.8 - 42 = x

x = 22.8
