1)The mean of the data 12,x,28 is 18. Find the value of x.
a)18
b)16
c)14
d)22​

Answer 1

Answer:

18= 12+x+28/3

18=40+x/3

54=40+x

x= 14

so the missing number is 14=x

correct answer is c)14

Answer 2

Answer:

The answer will be 14.

Step-by-step explanation:

Mean of data basically means the average of data.

Thus, (12+ x+ 28) / 3 = 18

(x + 40) = 18 ×3

x = 54 - 40

x = 14.

That's all.
