Question

find the mean proportion between 0.08 and 0.18

Answer 1

Let x be the mean proportion.
x^2 =(0. 08)*(0.18)=0.0144=(0.12)^2
x=0.12

Answer 2

Answer: The mean proportion is 0.12

Step-by-step explanation:

For finding the mean proportion

let the proportion be

0.08:x::x:0.18

Now as we know Product of mean = Product of extremes

therefore

$x\times x = 0.08 \times 0.18\\\\\Rightarrow x^2= 0.0144\\\\\Rightarrow x=\sqrt{0.0144} = 0.12$

Hence, the mean proportion is 0.12
