Answer:
mean = 52
Explanation:
In mathematics, the mean is a measure of central tendency that represents the average of a set of numbers. It is also commonly known as the arithmetic mean.
To calculate the mean, you add up all the numbers in a set and then divide by the total number of values in the set.
So in tho case we would add all the values then divide by the amount of values there are.
1) rewrite values:
42 45 58 63
2) add:
42 + 45 + 58 + 63
= 208
3) divide:
Since there arev4 values we will divide by 4.
208 / 4 = 52
Therefore, the mean is 52
