Answer:
d) 0.70.
Step-by-step explanation:
High School Education = 187 men
High School Education and former smoker = 54 men
High School Education and moderate smoker =41 men
High School Education and heavy smoker = 36 men
The proportion of men with a high school education that are current or former smokers is given by the sum of former, moderate and heavy smokers with a high school education divided by the total number of men with a high school education sampled:
The proportion is 0.70.

Step-by-step explanation:
Let the first unknown integer be x
Let the second unknown integer be y
Answer:
6.2 =x
Step-by-step explanation:
cos 70 =x/18
Multiply each side by 18
18cos 70 =x/18 *18
18cos 70 =x
6.15636258 = x
To the nearest tenth
6.2 =x
Answer:
Option A:
x^2 + (y - 2)^2 = 9
Step-by-step explanation:
We know that the equation for a circle centered in the point (a, b) and of radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
So the first thing we need to find is the center of the circle.
We can see that the center is at:
x = 0
y = 2
Then the center is at the point (0, 2)
Now we want our circle to pass through point 2, located at a distance of 2 units from the radius of the first circle.
So the distance between the center and point 2 is 2 units plus the radius of the smaller circle:
And the radius of the smaller circle is one unit.
Then, the radius of a circle centered at (0, 2) that passes through point 2 is:
R = 1 + 2 = 3
Then we have a circle centered at (0, 2) and of radius R = 3
Replacing these in the equation for a circle we get:
(x - 0)^2 + (y - 2)^2 = 3^2
x^2 + (y - 2)^2 = 9
The correct option is A
