Johan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. Which explains whether his solu
emmasim [6.3K]

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.

Someone has conducted a study to see if there is increased risk of getting lung cancer if you work in a coal mine. In group 1, 3
AleksandrR [38]

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.

\text{P(Lung cancer for coal miner)} = \dfrac{30}{150} = \dfrac{1}{5}

Group 2 of non-coal miners: 5 out of 250 get lung cancer

\text{P(Lung cancer for non-coal miner)} = \dfrac{5}{250} = \dfrac{1}{50}

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 =

\dfrac{\text{P(lung cancer for coal miner)}}{\text{P(lung cancer for non coal miner)}}\\\\=\dfrac{\frac{1}{5}}{\frac{1}{50}} = \dfrac{50}{5} = 10

Thus, sample relative risk is 10.
