Answer:

23.2 cm

Step-by-step explanation:

For the angle of 53.2 deg, x is the opposite leg. The hypotenuse is 29 cm.

sin A = opp/hyp

sin 53.2 deg = x/29 cm

x = 29 cm * sin 53.2 deg

x = 23.2 cm

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.

Bob is driving along a straight and level road toward a mountain. At some point on his trip, he measures the angle of elevation
DerKrebs [107]

Answer:

Option A.

Step-by-step explanation:

Distance between Bob and the center of the mountain at the base = 19,427.5 ft.

Angle of elevation to the top of the mountain = 25°11'

We know that

1 degree = 60 minutes

1/60 degree = 1 minute

25^{\circ}11'=25^{\circ}+\frac{11}{60}{\circ}\Rightarrow 25^{\circ}+0.183^{\circ}=25.183^{\circ}

Let the height of the mountain be h.

In a right angled triangle

\tan\theta = \frac{opposite}{adjacent}

\tan(25.183^{\circ}) = \frac{h}{19427.5}

\tan(25.183^{\circ})\times 19427.5 = h

h=0.4702\times 19427.5

h=9134.8105

h\approx 9135

Therefore, the height of the mountain to the nearest foot 9135. Option A is correct.
