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%.
Answer:
(-21)/20
Step-by-step explanation:
Simplify the following:
-(2 + 1/4) - 2/3 (1/5 - 2)
Put 2 + 1/4 over the common denominator 4. 2 + 1/4 = (4×2)/4 + 1/4:
-(4×2)/4 + 1/4 - 2/3 (1/5 - 2)
4×2 = 8:
-(8/4 + 1/4) - 2/3 (1/5 - 2)
8/4 + 1/4 = (8 + 1)/4:
-(8 + 1)/4 - 2/3 (1/5 - 2)
8 + 1 = 9:
-9/4 - 2/3 (1/5 - 2)
Put -2 + 1/5 over the common denominator 5. -2 + 1/5 = (5 (-2))/5 + 1/5:
-9/4 - 2/3 1/5 + (5 (-2))/5
5 (-2) = -10:
-9/4 - 2/3 ((-10)/5 + 1/5)
-10/5 + 1/5 = (-10 + 1)/5:
-9/4 - 2/3 (1 - 10)/5
-10 + 1 = -9:
-9/4 - 2/3×(-9)/5
-2 (-9) = 18:
(-9)/4 + 18/(3×5)
3×5 = 15:
(-9)/4 + 18/15
The gcd of 18 and 15 is 3, so 18/15 = (3×6)/(3×5) = 3/3×6/5 = 6/5:
(-9)/4 + 6/5
Put (-9)/4 + 6/5 over the common denominator 20. (-9)/4 + 6/5 = (5 (-9))/20 + (4×6)/20:
(5 (-9))/20 + (4×6)/20
5 (-9) = -45:
(-45)/20 + (4×6)/20
4×6 = 24:
(-45)/20 + 24/20
-45/20 + 24/20 = (-45 + 24)/20:
(-45 + 24)/20
-45 + 24 = -21:
Answer: (-21)/20
Answer:
Step-by-step explanation:
A: 3*4+2
B: The shoe rental is 2 dollar. Since the cost per game is 4 dollar you will need to multiply by the 3 game you pay then subtract 14-12 and get 2 which is the rental fee
