Answer 1

Hi

Here is ur answer

Mean: Adding all the given numbers and dividing it by the numbers of number present init.

It is given that mean = 30

Therefore,

20 + 24 + 36 + 26 + 34 + k / 6 = 30

140 + k = 180

k = 180 / 140

Zeros will get cancelled out,

k = 18 / 14

k = 9 / 7

Therefore,

k = 1.28

Hope it helps U
