840 students in the school would be expected to play outdoor games for at least three hours every week, which is correct option (C)
What are Arithmetic operations?
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
Given that a random sample of 100 middle school students
30 + 62 + 8 = 100
100 x 12 = 1,200
100 x 12 = 1,200
Every week, at least three hours of outdoor games are required for the school's 840/1,200 students.
70 out of 100 people participate in activities for at least three hours each week.
70 x 12 = 840
Hence, 840 students in the school would be expected to play outdoor games for at least three hours every week
