Answer:

37.925

Step-by-step explanation:

you have given only 4 students weights.

average of 5 students = total / 5

average of 4 students = (38.5+42.8+36.7+33.7)/4

= 151.7/4 = 37.925

38 approx.

Answer 2

37.875 kg

Step-by-step explanation:

The total weight of the boys is- (38.5+42.8+36.7+33.7)kg
