Question

5. Find the mean proportion of the following:
(b) 4,9
(a) 5, 20​

Answer 1

Step-by-step explanation:

Mean proportion between two number is defined as the square root of the product of the numbers.

i.e. M=\sqrt{x\times y}M=

x×y

Let the number x=4 and y=9.

So, Mean proportion between them is

M=\sqrt{4\times 9}M=

4×9

M=\sqrt{36}M=

36

M=6M=6

Therefore, The mean proportional between 4 and 9 is 6.
