Answer:
Step-by-step explanation:
given that an article in the Sacramento Bee (March 8, 1984, p. A1) reported on a study finding that "men who drank 500 ounces or more of beer a month (about 16 ounces a day) were three times more likely to develop cancer of the rectum than non-drinkers."
To support this some data collected should be given. The data should be from a sample of a large size randomly drawn from 2 groups one men who drank 500 oz or more of beer and other group not drank that much. These people medical history with cancer patients number also should have been given.
Answer:

Step-by-step explanation:
So the number of questions in an exam varies with the number of minutes to take the exam.
For each question there are 5 minutes allotted.
Lets say that there are 'x' number of questions in the exam and 't' is the total time taken to finish the exam, in minutes. So the time taken to complete the exam would be

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

So there are two variables in the equation, 't', and 'x':
t - time taken to complete the exam
x - number of questions on the exam
Slope= (y2-y1)/(x2-X1)
1=(9-3)/(3-x)
1=6/(3-x)
3-x=6
X=9
1km = 1000m
1h = 60min = 3600s
