Question

The mean proportional between 4 and 9 is

Answer 1

mean proportional means the squareroot of the product of two no = squareroot of 36= 6

Answer 2

Answer:

The mean proportional between 4 and 9 is 6.

Step-by-step explanation:

Given : Number between 4 and 9.

To find : The mean proportional between 4 and 9?

Solution :

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

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

Let the number x=4 and y=9.

So, Mean proportion between them is

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

$M=\sqrt{36}$

$M=6$

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