Final answer:
Approximately 429 freshmen from a class of 750 are expected to graduate if 4 out of 7 students graduate in 4 years.
Step-by-step explanation:
The student is asking how many freshmen are expected to graduate from a class of 750 students if 4 out of 7 graduate in 4 years. To find the answer, multiply the total number of students by the fraction of students expected to graduate:
(750 students) × (4/7) = 428.5714286
Since we cannot have a fraction of a student, we round to the nearest whole number, which gives us approximately 429 students expected to graduate. Therefore, the correct answer is C) 429.
