No because that would just be measuring freshman a better sampling method would be surveying the same number of students for each grade
Answer:
r=8.66025403784
Step-by-step explanation:
7065=π(r squared)X30
7065=94.2(r squared)
7065÷94.2=r squared
√75=r squared
8.66025403784=r
Tn=3n-5
therefore: T(3)=3(3)-5
T(3) =4
1 inch = 13.5 feet
5 inches = 5 * 13.5 = 67.5 feet
Answer:
5 meters per minute or 5/1 or 5:1
