All the probabilities are given for the three different scenarios in men and women: people who smoke, people who develop lung cancer, and people who develop lung cancer who are also smokers. Then, these are even classified in terms of gender.

But the final question only has to do with men who are smokers that develop lung cancer. So, I think all the other data are only there for the purpose of red herring. The answer is already there, but you just have to find it among the others. First, you ignore all the probabilities involving women because we only want the men. Then, you find the probability of men that have lung cancer being smokers. The answer is 90%.

An amusement park charges admission plus a fee for each ride. Admission plus four ride cost $22. Admission plus seven ride cost
nignag [31]

Answer:

Admission fee charged = $3

Cost of each ride = $10

Step-by-step explanation:

Let admission fee charged by amusement park in dollars be =x

Let cost of each ride in dollars be =y

Given:

Admission plus four rides cost $22

If each ride cost in dollars = y

Cost of 4 rides in dollars will be  = 4y

So, the total cost in dollars will be given as =x+4y

So, we have

x+4y=22

Admission plus seven ride cost $31.

If each ride cost in dollars = y

Cost of 7 rides in dollars will be  = 7y

So, the total cost in dollars will be given as =x+7y

So, we have

x+7y=31

So, we have the system of equation as:

A) x+4y=22

B) x+7y=31

Solving the system by elimination method.

Eliminating x by subtracting equation A from B.

   x+7y=31

- x+4y=22

   -       -      -  [Sign of each term of subtract-ant gets reversed]

-----------------------------

      3y=9

Dividing both sides by 3.

\frac{3y}{3}=\frac{9}{3}

∴ y=3

Plugging in y=3 in equation A.

x+4(3)=22

x+12=22

Subtracting both sides by 12.

x+12-12=22-12

∴ x=10

Thus, admission fee charged = $3

Cost of each ride = $10

Larry bought 2⁄3 pound of red potatoes and 3⁄4 pound of golden potatoes. How many pounds of potatoes did he buy in all?
Xelga [282]

Common denominator between 3 and 4 is 12. 2/3 becomes 8/12, and 3/4 becomes 9/12. Add them to get 17/12, which equals 1 and 5/12 lbs.
