On a 50 -question test, a student answered 5 questions incorrectly. What percent did the student answer correctly? A) \( 10 \% \) B) \( 90 \% \) C) \( 55 \% \) D) \( 45 \% \) Question 9 ( 5 points)

To find the percentage of questions the student answered correctly, we first need to determine how many questions were answered correctly. The student answered 5 questions incorrectly out of a total of 50 questions. Therefore, the number of questions answered correctly is: \[ 50 - 5 = 45 \] Next, we calculate the percentage of questions answered correctly: \[ \text{Percentage correct} = \left( \frac{\text{Number of correct answers}}{\text{Total number of questions}} \right) \times 100 \] Substituting the values we have: \[ \text{Percentage correct} = \left( \frac{45}{50} \right) \times 100 = 0.9 \times 100 = 90\% \] Thus, the student answered \( 90\% \) of the questions correctly. The correct answer is **B) 90%**.
