Question

practice: find the averages
find the average: 0.21 0.77 0.51 0.65 0.32
sum:
count:
divide:
average:

Explanation:

Step1: Recall the average formula

The formula for the average (arithmetic - mean) of a set of numbers is $\text{Average}=\frac{\text{Sum}}{\text{Count}}$. First, we need to find the sum of the numbers.

Step2: Calculate the sum

The numbers are $0.21,0.77,0.51,0.65,0.32$. The sum $S = 0.21+0.77 + 0.51+0.65+0.32=2.46$.

Step3: Determine the count

The count of numbers $n = 5$.

Step4: Calculate the average

Using the formula $\text{Average}=\frac{S}{n}$, we substitute $S = 2.46$ and $n = 5$. So, $\text{Average}=\frac{2.46}{5}=0.492$.

Answer:

$0.492$
