Answer :
set up a proportion putting x in the means location
6/x=x/20
cross multiply
x^2= 120
x= square root of 120
10.95 or 2 square root of 30
The geometric mean between 6 and 20 is;10.95
Geometric mean
According to the question;
- We are required to determine the geometric mean between 6 and 20.
Hence, geometric mean of both numbers can be evaluated as follows;
- G.M = √6 × 20
- G.M = √120.
- G.M = 10.95.
