Introduction to mean:
The mean is also called average. The arithmetic mean is found by adding the numbers in the list and dividing the sum by the number of numbers in the list.
Mean = (Sum of all the observations/Total number of observations)
Given:
Darryl's credit scores are Experian score is 719, Equifax's score is 741, and Transunion's score is 780.
To find the mean we have to add the given values i.e., the sum of Experian score, Equifax's score, and Transunion's score.
719+741+780
there are a total of 3 scores so we have to divide them by 3.
[tex]\frac{719+741+780}{3}[/tex]
≅[tex]746.67[/tex]
The nearest whole point is 747.
