Question

The mean of 12+x,14+2x,16,18+x, 20,22-x and 24-3x is​

Answer 1

Step-by-step explanation:

We know that mean=sum of all observations/total no.of observations

sum of all observations=12+x+14+2x+16+18+x+20+22-x+24-3x

=4x-4x+128

=126

no.of observations=7

therefore,

mean =no.of the observations/total no.of observations

=126/7

=18

hence,the mean is 18
