Answer:

Step-by-step explanation:

From the above question, we are solving for an Algebraic Equation

2(3x - 4) + 5x = -41 = Given

(6x - 8) + 5x = -41 Distributive Property. 6x + 5x – 8= -41

11x - 8 = -41 Write an equivalent equation

11x = -33 Addition of Property of Equality

x = -3 Division Property of Equality

The reason that is missing from the proof is:

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.

Sergio is S years old. Which expression shows how old will he be 7 years from now?
aniked [119]
The answer is C.

If Sergio is 'S' years old, and you want to know how old he'll be in 7 years, add 7 years to his age.

So: s + 7

Hope this helps!
