Answer:
765
Step-by-step explanation:
4500x8,5= 38250/100=382,5 x2= 765
Answer:0.789
Step-by-step explanation:
20 % person smokes and 80 % don't smoke
Probability that a smoker gets lung cancer=15%
Probability that a non smoker gets lung cancer is =1%
Thus
Probability if a person is diagnosed with cancer he/she is a smoker
P=![\frac{Smoker}{Given he gets cancer}](https://tex.z-dn.net/?f=%5Cfrac%7BSmoker%7D%7BGiven%20he%20gets%20cancer%7D)
P=![\frac{0.2\times 0.15}{0.8\times 0.01+0.2\times 0.15}](https://tex.z-dn.net/?f=%5Cfrac%7B0.2%5Ctimes%200.15%7D%7B0.8%5Ctimes%200.01%2B0.2%5Ctimes%200.15%7D)
P=
=0.789
Part A) The area of a parallelogram is base × height.
3 × 2/3 = 6/3 = 2
2 feet squared is the area of the whole parallelogram.
Part B) The diagonal of a parallelogram separates it into two congruent triangles.
The area of each triangle will be:
base × height × 1/2
3 × 2/3 × 1/2 = 6/6 = 1
1 foot squared is the area for each triangle.
