Question

Find the average value of the following numbers 87, 79, 84, 70, 90

Answer 1

82

Step-by-step explanation

the average is calculated by dividing the sum of the values in the set by their number.

Step 1

Let

`\begin{gathered} \text{set}=\lbrace87,79,84,70,90\rbrace \\ the\text{ sum of the values is=87+79+84+70+90}=410 \\ n\text{umber of values= 5} \end{gathered}`

Step 2

apply the equation

`\text{Average}=\text{ }\frac{the\text{ sum of the values}}{\\u mber\text{ of values}}=(410)/(5)=82`

so, the answer is 82
