Answer:
A measure of exposure-disease association one could use is the odds ratio (OR)
Step-by-step explanation:
An Odds ratio (OR) is a statistical measure quantifying the level of association between two events such as an exposure and an outcome
The odds ratio gives the probability of outcome where there is a given amount of exposure
We have the table;
The odds ratio = (The number of smokers with the lung-cancer)/(The number of non-smokers with lung-cancer) ÷ (The number of smokers smokers without long cancer).(The number of non-smokers without long cancer)
∴ OR = (50/10) ÷ (350/590) = 59/7 = 8.
≈ 8.4
Therefore, a smoker is approximately 8.4 times more likely to develop lung cancer than a non-smoker.
Answer:
108 degrees
Step-by-step explanation:
Given
Let the angles be A and B
Required
Find the larger angle
If both angles form linear pair, then the following relationship exist:
Substitute values for A and B

Solve for x
Substitute 13.5 for x in
<em>Hence, the larger angle measures 108</em>
TheThe area of the shaded region if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.
<h3>Area of the shaded region</h3>
Area of a circle = πr²
r =radius of the circle
Area of the outer circle:
Area of the outer circle = π(4)²
Area of the outer circle = 16π
Area of the inner circle:
Area of the inner circle = π (2)²
Area of the inner circle = 4 π
Area of the shaded Region :
Area of the shaded Region = 16π - 4 π
Area of the shaded Region = 12π
Therefore the area of the shaded region if the radius of the outer circle is 4 and the radius of the inner circle is 2 is 12π.

Answer:
124 miles
Step-by-step explanation:
simplify mixed fraction as
6 1 / 5 = 31/5 inches
on the map 1 inch represent 20 miles
31/5 × 20
= (31 × 20)/5
= 620/5
= 124 miles
the distance between those two towns will be 124 miles.
