The sample relative risk is 10.

<h3>What is relative risk? </h3>

Sample relative risk is the ratio of disease risk or death in an exposed group to the disease risk or death in an unexposed group. Sample relative risk is a descriptive statistic.

What is the sample relative risk?

Sample relative risk = fraction of coal miner who got lung cancer / fraction of non coal miners who got lung cancer

Sample relative risk = (30 / 150) ÷ (5/250)

(1/5) ÷ (1/50

1/5 x 50 = 10

Given:

EFGH is a square.

To find:

The m\angle FHG.

Solution:

We know that all interior angles of a square are right angles.

m\angle EHG=90^\circ              (Right angle)

The diagonals of square are always the angle bisectors.

FH is a diagonal of the square. So, it bisects the angle EHG.

m\angle FHG=\dfrac{m\angle EHG}{2}

m\angle FHG=\dfrac{90^\circ}{2}

m\angle FHG=45^\circ

Therefore, the measure of angle FHG is 45 degrees.

Nostrana [21]
Given:
loan amount: 25,250
original interest rate: 3.4%
new interest rate: 6.8%
term: 10 years.

Assuming that simple interest formula is used.
I = P * r * t
I = interest
P = principal
r = interest rate
t = term/time

I = 25,250 * 3.4% * 10 years
I = 8,585

I = 25,250 * 6.8% * 10 years
I = 17,170

17,170 - 8,585 = 8,585 Additional interest paid using the new interest rate.

. One car traveled 210 miles and drove 20 mph hour faster than a second car drove 150 miles. If the cars were traveling for the
inn [45]

Answer:

The first car was traveling 70 mph, while the second was driving 50 mph.

Step-by-step explanation:

Set the cars as a proportion:

\frac{210}{x + 2}  =  \frac{150}{x}

X represents the speed of the second car. By cross multiplying, you get the following equation:

210x = 150(x + 20)

You solve by distributing 150 to get 210x = 150x + 3000.

Solving for x gets you 50.

That means the first car was going at 50 mph. Adding 20, you get 70 as the speed for the second car.
