Dear Westbrookalisha, your question is very vague. I don't see the worksheet or the problem you want us to solve.
Answer:
Cluster sample
Step-by-step explanation:
Samples may be classified as:
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this problem, we have that:
Selection of groups according to the buses.
All members on those buses are pulled.
So this is an cluster sample.
I got this answer by first using the slope formula, which would result into 
for which the answer would be - ⅔ Then, the y-intercept could be found easily, since you already have it., which is (0,4). Since the format for all linear equations are y=mx+b , in which b means the y-intercept and m means the slope. So then, if you substitute - ⅔ for m and 4 for b , you would get
Yo bro this is simple. what you need to do is assess the vocabulary
complement=90 degrees
supplementary=180 degrees
so you use the number you were given and subtract it from the complement and supplement angles.
180-56.9=123.1 which is the answer to the supplementary of angle j
90-56.9=33.1 which is the answer to the complementary angle of j.
so 123.1 and 33.1
P.S- I might be wrong but use at your own risk
