Answer 2

Answer:

The A.M (Arithmetic Mean) between 9 and 11 is 10.

Step-by-step explanation:

A.M or Arithmetic Mean is the average/mean of a given set of numbers.

The formula of A.M is

$= \frac{sum \: of \: all \: numbers \: in \: the \: set}{total \: number \: of \: numbers \: in \: the \: set}$

To understand this with a question:

The arithmetic mean of 9 and 11.

$= \frac{sum \: of \: all \: numbers \: in \: the \: set}{total \: number \: of \: numbers \: in \: the \: set}$

$= \frac{9 + 11}{2}$

$= \frac{20}{2}$

$= 10$

Therefore the A.M (Arithmetic Mean) of the numbers 9 and 11 is 10.
