Answer:
Sample relative risk is 10.
Step-by-step explanation:
We are given the following in the question:
Group 1 of coal miners: 30 out of 150 get lung cancer.
Group 2 of non-coal miners: 5 out of 250 get lung cancer
Sample relative risk:
- It is the ratio of probability of an outcome in an exposed group to the probability of an outcome in an unexposed group.
Sample relative risk =
Thus, sample relative risk is 10.
Answer:
End behavior :
1. As the x-values go to positive infinity, the function's values go to negative infinity
2. As the x-values go to negative infinity, the function's values go to positive infinity.
Option D: over the interval
(answer for question in image)
Step-by-step explanation:
From the given graph it is clear that as the x-values go to positive infinity, the function's values go to negative infinity and as the x-values go to negative infinity, the function's values go to positive infinity.
It means,
At x=0, the value of function is -3.
Note: All options are incorrect for end behavior.
From the given graph it is clear that the function is above the x-axis before -4 and after that it is below the x-axis. So,
over the interval
over the interval
Therefore, the correct option is D.
