Answer:
Depends on amount of students.
Step-by-step explanation:
You would just multiply the amount of students time (1 1/2) = (1.5)
Ex:
3 students 4 1/2 hours
4 students 6 hours
5 students 7 1/2 hours
and so on
Mean absolute deviation= 3.6
Standard deviation=4.19
N+m/p=q
Multiply by p
Np+m=pq
Subtract m
Np=pq-m
Divide by p
N=(pq-m)/p
I hope this helps you
p-9 < -9
p-9+9 < -9+9
p <0
