D) No, Maddie is incorrect because the number of students wearing red is not mentioned.

Answer 1

Maddie is correct in saying that 30% of her classmates were wearing red; by calculating (9/30) × 100, we confirm that 30% of 30 students is indeed 9 students.

Step-by-step explanation:

The question is asking whether Maddie is correct in saying that 30% of her classmates were wearing red. To find the percentage of students wearing red, we calculate the ratio of the number of students wearing red to the total number of students in the class. This ratio is then multiplied by 100 to get the percentage.

There are 30 students in total and 9 students wearing red. The percentage is calculated as follows:

(Number of students wearing red / Total number of students) × 100 = (9 / 30) × 100 = 0.3 × 100 = 30%

Therefore, the correct answer is A) Yes, Maddie is correct because 30% of 30 students is 9 students.
