Answer:
a) 7 were 30 or younger
4 of ≤ 30 and 3 of ≥ 30 has no facial hair
b) as attached
c) c) 5/15= 1/3 ( 33.33%) of men older than 30 has facial hair, in total group
0r 5/8 = 0.625 (62.5%) of men older than 30 in his age group has facial hair
Step-by-step explanation:
a) b) shown in attached
c) 5/15= 1/3 ( 33.33%) of men older than 30 has facial hair, in total group
0r 5/8 = 0.625 (62.5%) of men older than 30 in his age group has facial hair

The function represented by points A, B, and E is clearly modeled using an exponential function.
<h3>what is an exponential function?</h3>The function which is in format f(x) = where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here, the function has a rate of growth or decay for an uncertain period of time modeled as an exponential function..
A.The height of a plant each day that it grows.
⇒ This statement does not give the rate of growth, but we assume that it has a certain rate of growth, so it is an exponential modeled function.
B. The value of a savings bond increases 15% each year.
⇒ it is modeled as an exponential function.
C. Radioactive material decays by half every 2 hours.
⇒ it is also modeled as an exponential function.
D. Stephanie earns $14 an hour at her after-school job.
⇒ It is not an exponential function.
E. The population of a town grows 3% each year.
⇒ it is also modeled as an exponential function.
Thus, the function represented by points A, B, and E is clearly modeled using an exponential function.
