Answer:
The geometric mean is [tex]\sqrt{77}[/tex]
Option D is correct.
Step-by-step explanation:
Given: 7 and 11
We need to find the geometric mean of 7 and 11.
Geometric series whose common ration is equal.
Geometric mean of two number is square root of product of two number.
If a, b and c are in GP then geometric mean is b
[tex]b=\sqrt{ac}[/tex]
The geometric mean of any two number a and b is [tex]\sqrt{ab}[/tex]
The given numbers are 7 and 11
Geometric mean is [tex]\sqrt{7\times 11}[/tex]
Geometric mean: [tex]\sqrt{77}[/tex]
Hence, The geometric mean is [tex]\sqrt{77}[/tex]
