Step-by-step explanation:
<u>Plotting </u>
<u />
Step 1: determine the y-intercept

- plot the point as the first point on the graph
Step 2: Move 2 units up, and 1 unit left (keep repeating this process until you have reached the limit of the graph)
Step 3: Go to the other side of the graph of the first point (y-intercept)
- move 2 units down, and 1 unit right keep repeating this process until you have reached the limit of the graph)
<em>When you've completed this process, it should look like this:</em>
After arranging the data from least to greatest:
Q1: 12.5
Q3: 16
IQR ( Q3-Q1) : 3.5
Answer:
P = 10%
Step-by-step explanation:
Of means multiply and is means equals
P * 80 = 8
Divide each side by 80
P = 8/80
P = .1
Change to percent form
P = 10%
3:1 , 4*3=12, 5*1=5
Ratio is 3:1
