Explanation:

Step1: Recall the mean formula

The mean (average) of a set of numbers is calculated by summing all the numbers and then dividing by the count of numbers. The formula is $\text{Mean} = \frac{\sum_{i = 1}^{n} x_{i}}{n}$, where $x_{i}$ are the individual values and $n$ is the number of values. Here, $n = 3$ (three credit scores), and the values are $719$, $741$, and $780$.

Step2: Calculate the sum of the credit scores

First, we find the sum of the three scores: $719+741 + 780$. Let's calculate that: $719+741=1460$, and then $1460 + 780=2240$.

Step3: Calculate the mean

Now, we divide the sum by the number of scores ($n = 3$). So, $\text{Mean}=\frac{2240}{3}\approx746.67$. Rounding to the nearest whole point, we get $747$.

Answer:

d. 747
