The answer is <span>c. cutting all meats with the same knife. because if you use the same knife to cut one meat with can you cut something else with it, then the bacteria from the first meat just got on the second one. </span>
I'm not entirely sure but I think this is true (?) because rescue breathing should only be used if any of the following happened to the victim: drowning, drug overdose, collapse due to breathing problems, an unresponsiveness in infants or children, an unconsciousness adult that isn't breathing normally, and if they are having prolonged cardiac arrest.
Hope this helps! :)
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
