Answer:
C. 0 ≤ y ≤ 8
Step-by-step explanation:
In any graph, the range represents the 'y' values covered by the graph. The 'y' axis is the vertical (up and down) line on the graph. Given the graph, it stops at the point (0, 8) on the top and at (-6,0) and (6,0) on the bottom. This would be an overall range of 0 ≤ y ≤ 8.

Answer:
a) cluster sampling
Step-by-step explanation:
In cluster sampling method, each member of a population is assigned to one and only one group.This means clusters are formed through probability method usually a simple random sampling.The participants in the clusters are the only one to be surveyed.
In this example, simple random sampling is used to identify 12 home rooms(cluster) where a group of 20 students (participants) in each room is given the survey.
Answer:
The slope is 1/3
Step-by-step explanation:
Take 2 points on the line, lets use (0,50) and (30,60)
x1 y1 x2 y2
Use slope formula:
y2 - y1 / x2 - x1
60 - 50 / 30 - 0
10 / 30
which can be simplified to:
1/3
