Answer:
Cluster sample
Step-by-step explanation:
This is an example of a cluster sample. In a cluster sample, the examiner divides the population into groups (each one of these groups is called a cluster) and once the examiner has these clusters, takes one of them and recollects the data from ALL the members of that cluster. In this case, the teacher divided the class in 3 different groups and then selects one of these groups and asks the average amount of time per week he/she spent studying.
X and y
x=4/9 times y
y is bigger so
y-x=375
x=4/9y
y-4/9y=375
5/9y=375
times both sides by 9/5
y=675
the 2nd number is 675
