Question

find the average of these numbers: 3, 3, 3, 3, 3, 3, 3, 4, 5, 6, 7* 5 poin 3 3.4 3.9 4.1 7

Explanation:

Step1: Calculate the sum of the numbers

There are 7 threes, one four, one five, one six and one seven.
The sum \(S=3\times7 + 4+5+6+7=21 + 4+5+6+7=43\)

Step2: Calculate the number of elements

Count the numbers: \(n = 7+1+1+1+1=11\)

Step3: Calculate the average

The average \(\bar{x}=\frac{S}{n}=\frac{43}{11}\approx3.9\)

Answer:

3.9
