Question

find the mean proportion of the following 1.) 15,20.. 2)49,36​

Answer 1

Answer:

Iam not sure but I think its 36

Answer 2

Answer 1) 17.3 and 2) 42

Step-by-step explanation:

1) Let x be the mean proportion of 15 and 20

15 : x : x: 20

This can be

15/x = x/20

x^2 = 15*20

x^2 = 300

x = 17.3 approx

2) let x be mean proportion of 49 and 36

49/x = 36/x

x^2 = 49*36

x^2 = 1764

x = 42
