Find the mean of the numbers 1, 3, 4, 8, 8, 4 and 7
Answer Details
To find the mean of a set of numbers, we add up all the numbers and then divide the sum by the total number of numbers.
So, in this case, we add up the numbers:
$$1+3+4+8+8+4+7=35$$
There are 7 numbers in the set, so we divide the sum by 7 to get:
$$\frac{1+3+4+8+8+4+7}{7}=\frac{35}{7}=5$$
Therefore, the mean (also known as the average) of the numbers 1, 3, 4, 8, 8, 4, and 7 is 5.
So, the correct answer is 5.
