Question

The mean weight of six children is 17.5 kg. If the individual weights of five of these children are 14, 19, 23, 21 and 13 kg respectively, find the weight of the sixth child.​

Answer 1

Answer:

Hi !!!!!!

Mean = 17.5

let the weight of the sixth child be "x"

(14+19+23+21+13+x)/6 = 17.5

(90+x)/6 = 17.5

90+x = 105

x = (105-90)

x = 15

Thus, the weight of the sixth child is 15kg.
