Spencer has surveyed five of his friends to known that how many pets they have.

His results are shown in the table below. Cody has 1 Lara has 4 Sam has 5 Ella has 3 Maria has 2. There are total 5 friends. Thus the mean number of pets is:

$\text{Mean}=\dfrac{1+4+5+3+2}{5}\\\text{Mean}=\dfrac{15}{5}\\\text{Mean}=3$

Thus, the mean of the number of pets which Spencer has surveyed for five of his friends is number 3.

Step-by-step explanation:

Range of a function is the value that we get when a function is solved.

Say, f(x) = y.

We say this "set of x is domain" whereas "set of y is range".

Suppose,

set A = {1,2} & set B = {1,2,3} & f(x) = y

Let,

f(1) = 1, & f(2) = 2.

What we get is that there is no x for 3.

We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.
