Final answer:
Wayne answered 10.77% of the questions incorrectly on the test by subtracting the number of correct answers from the total, then dividing the number of incorrect answers by the total and multiplying by 100.
Step-by-step explanation:
Wayne answered 58 out of 65 questions correctly on a test. To find the percentage he answered incorrectly, we first need to determine the number of questions he answered incorrectly. This can be done by subtracting the number of correct answers (58) from the total number of questions (65), which gives us 7 incorrect answers.
To convert this to a percentage, we'll then divide the number of incorrect answers by the total number of questions and multiply by 100:
Percentage incorrect = (Number of incorrect answers / Total number of questions) × 10
Percentage incorrect = (7 / 65) × 100
Percentage incorrect = 0.1077 × 100
Percentage incorrect = 10.77%
So, Wayne answered approximately 10.77% of the questions incorrectly on the test.
