Answer 2

Answer:

Mean of given numbers is $7.5$ .

Step-by-step explanation:

To find: mean of given numbers

Given data : $4,6,12, 8$

Solution :

• Average is the arithmetic mean also called as mean .
• It is the ratio of sum of all the numbers given in data to the total number of observations.
• Formula: $Average \ or \ mean =\frac{\text { sum of all the observations }}{\text { total of observations }}$
• Here, sum of observations $= 4 +6+12+8$

                                                     $= 30$

• Total number of observations $= 4$
• Substituting values in above formula,

       $\begin{array}{r}\text { Average\ or \ mean }=\frac{30}{4} \\=7.5\end{array}$
