Question

FIND THE MEAN PROPORTION BETWEEN 1.25 AND 0.45

Answer 1

Step-by-step explanation:

let the mean proportional be x

1.25/x = x/0.45

x² = 0.5625

x = 0.75

Mean proportion of two numbers means square root of product of two numbers.

∴ Mean proportion of 1.25 & 0.45

$= \sqrt{1.25 \times 0.45}$

$= \sqrt{0.5625}$

$= \sqrt{0.75 \times 0.75}$
