Explanation:
The suggested number of sleep hours for teens is between 8 to 10 hours daily.
<h3>
Sleeping hours of teens</h3>
This is the estimated time in which teens are expected to sleep or have full rest.
The average estimated time of sleep hours for teens is between 8 to 10 hours. This may vary according to health condition of individuals.
Thus, the suggested number of sleep hours for teens is between 8 to 10 hours daily.

Answer:
D
Explanation:
add all the know sides 8+8+3+5=24
perimeter of half a semicircle=circumference of half a semicircle
if circle is C=π×d
than semi C=1/2×d×π
C=½×4×π
C=2pi
so 24+2pi
Using the binomial distribution, it is found that there is a:
- 0.0036 = 0.36% probability that both are allergic to pollen.
- 0.1164 = 11.64% probability that at least one is allergic to pollen.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Researching the problem on the internet, it is found that:
- 6% of the population is allergic to pollen, hence p = 0.06.
- Two people are chosen at random, hence n = 2.
The probability that both are allergic is P(X = 2), hence:
P(X = 2) = 0.06^2 = 0.0036.
0.0036 = 0.36% probability that both are allergic to pollen.
The probability of at least one is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.94^2 = 1 - 0.8836 = 0.1164.
0.1164 = 11.64% probability that at least one is allergic to pollen.
