Answer:
6.
Step-by-step explanation:
The mean of a set of numbers is the sum of all the numbers divided by the total number of values.
To find the mean of the set of numbers you provided (12, 3, 3, 4, 8), you need to add all the numbers together and then divide the sum by the total number of values.
Adding the numbers together, we get:
12 + 3 + 3 + 4 + 8 = 30
Since there are 5 numbers in the set, we divide the sum by 5:
30 รท 5 = 6
Therefore, the mean of the set of numbers (12, 3, 3, 4, 8) is 6.
In other words, on average, the numbers in the set add up to 6.
