Blood picks up nutrient from the digestive system and takes it into the cells. The jejunum in the small intestine is the site of nutrients absorption into the blood. The nutrients which are absorbed into the blood stream are carried by the blood into the cells of the body. Cells use these nutrients for their metabolic activities.

Answer:
a. The expected number of adults who smoke is 70
b. The probability that fewer than 20 smoke is 5.7%
c. The probability that from 45 to 80 smoke is the 12,8% to 22,8%
d. The probability that 70 or more smoke is the 20%
Explanation:
a. 350 is the 100% so you have to do a equation
350 -100%
X - 20% = 20% x 350/100 = 70 adults
b. 350 -100%
20 - X = 20% x 100%/350= 5.7% probability
c. 350 - 100%
45 - X = 45 x 100%/350= 12.8% probability
350 - 100%
80 - X = 80 x 100%/350= 22.8% probability
d. 350 - 100%
70 - X = 70 x 100%/350= 20% probability
