d

Explanation:

Step1: Identify the scores

The scores are 690 (Experian), 691 (Equifax), 651 (TransUnion). Wait, wait, no—wait, the problem says "his Experian score is 690, his Equifax score is 691, and his TransUnion score is 651". Wait, the original text: "His Experian score is 690, his Equifax score is 691, and his TransUnion score is 651. What is his mean credit score? (Round to the nearest whole point, if applicable.)" Wait, the options: a. 677, b. 671, c. 665, d. 690. Wait, let's recalculate.

Wait, mean is sum of scores divided by number of scores. So sum = 690 + 691 + 651. Let's compute that. 690 + 691 = 1381; 1381 + 651 = 2032. Then divide by 3: 2032 / 3 ≈ 677.333..., which rounds to 677. Wait, but let's check again. Wait, maybe I misread the TransUnion score. Wait, the problem says "his TransUnion score is 651". So three scores: 690, 691, 651. Sum: 690 + 691 = 1381; 1381 + 651 = 2032. 2032 ÷ 3 ≈ 677.33, which rounds to 677. So the answer should be a. 677.

Wait, but let's check the options again. The options are a. 677, b. 671, c. 665, d. 690. So yes, 2032 divided by 3 is approximately 677.33, which rounds to 677. So the correct option is a. 677.

Step1: Sum the credit scores

The three credit scores are 690 (Experian), 691 (Equifax), and 651 (TransUnion). The sum is calculated as:

$$ 690 + 691 + 651 = 2032 $$

Step2: Calculate the mean

The mean (average) is the sum divided by the number of scores (3). So:

$$ \text{Mean} = \frac{2032}{3} \approx 677.33 $$

Step3: Round to the nearest whole number

Rounding 677.33 to the nearest whole number gives 677.

Answer:

a. 677
