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
No, these fumes will not cause cancer nor will damage your hair. The only thing truly damaging your hair is blow drying it every day because it can dry it out, so try not to do that! It is not that bad though.
Answer:
Talk to her.
Explanation:
Make sure your approachable and be there for her. Let her know that she can talk to you. Confront her about it but don't press her about it. E.g. pull her aside to where it's just you and her "Sondra I noticed the pill bottle... you know you can always talk to me" or tell a trusted adult to help.
