Step-by-step explanation:
Answer:
He is not correct because he made a sign error.
Step-by-step explanation:
-2 |8-x| - 6 = -12
-2 |8-x| = -12 + 6
-2 |8-x| = - 6
2 |8-x| = 6
|8-x| = 3
2 possible solutions:
8-x = 3 ----> x = 5
or
8-x = -3 ----> x = 11
Comparing the answer choices, we can see that Johan got the sign of x = 11 wrong.
Hence the correct answer is:
He is not correct because he made a sign error.
L=0×r
l=3π/5×7
l=22×3×7÷7÷5
l=66/5
l=13.2 units

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.
