Answer: 5.1
Explanation:
The mean, also known as the average, is calculated by adding up all the numbers in a set and then dividing the sum by the total number of values in the set.
To find the mean of the given set of numbers: 5.2, 5.3, 5.7, 5.7, 7, 1
Step 1: Add up all the numbers:
5.2 + 5.3 + 5.7 + 5.7 + 7 + 1 = 30.6
Step 2: Count the total number of values in the set:
There are 6 values in the set.
Step 3: Divide the sum by the total number of values:
30.6 ÷ 6 = 5.1
Therefore, the mean of the given set of numbers is 5.1.
In summary, to find the mean, you add up all the numbers and then divide the sum by the total number of values in the set.
