Question

The ratio of the mean proportional of 0.02 and 0.08 and the geometric mean of 12 and 27 is

Answer 1

did you confuse " mean proportional" ?

oh, " mean proportional" is referred as " geometric mean" .

we know, if positive two numbers a and b are given then, geometric mean/ mean proportional of a and b is given by, $x=\sqrt{ab}$

so, mean proportional of 0.02 and 0.08

= √(0.02 × 0.08)

= √(0.02 × 0.02 × 4)

= 0.02 × 2 = 0.04

and geometric mean of 12 and 27

= √(12 × 27)

= √(2 × 2 × 3 × 3 × 3 × 3)

= 2 × 3 × 3

= 18

now, the ratio of mean proportional of 0.02 and 0.08 and the geomagnetic mean of 12 and 27 = 0.04/18 = 0.02/9

= 2/900 = 1/450

Answer 2

Answer:

Step-by-step explanation:

Root over 0.02*0.08=0.0016

Root over 12*27

Root over 324=18
