it is n+11 = y - 11
11? 11.0?
The mean is 7.375. You can find this by adding all the numbers in the set then dividing the sum by the amount of numbers in the set.
In retrospect, no.
geometric mean of 275 and 11=√(275x11)=√3,025=55

If your question refers to the Geometric Mean of 9 and 11 then the GM of any two numbers is √ab. Then the GM of 9 and 11 = √(9 x 11) = √99 = 9.9499 (5sf)
Geometric Mean of two numbers is the square root of their product, in this case root 77 ie 8.775
A geometric shape that has 11 sides is called a "hendecagon" or "undecagon." Both terms are acceptable.

12 choices for the first book, 11 choices for the second, 10 choices for the third, and 9 choices for the fourth. 12 x 11 x 10 x 9 = 11880.
The mean (average) of those numbers is 16.
