(b) The average of 22, 26, 24, 28, 30, 28 and x is 26 find the value of x.​

Answer 1

Answer:

Here is the answer mate

Step-by-step explanation:

a) Mean(X)=sum of total terms/total no of terms

=(16+14+12+9+15+18+19+8+12+15)/10

=138/10

=13.8

b)As per the sum

(22+26+24+28+30+28+x)/7=26

158+x=26*7

158+x=182

x=182-158

x=24
