Complete Question
A hypothetical population consists of eight individuals ages 13 14 17 20 21 22 24 30 years.
A: what is the probability that a person in this population is a teenager?
B: what is the probability of selecting a participant who is at least 20 years old?
We have that probability that a person in this population is a teenager and probability of selecting a participant who is at least 20 years old is
From the question we are told
A hypothetical population consists of eight individuals ages 13, 14, 17, 20, 21, 22, 24, & 30 years.
a)
Generally the equation for the probability that a person in this population is a teenager is mathematically given as
P(T)=0.38
b)
Generally the equation for the probability of selecting a participant who is at least 20 years old is mathematically given as
P(T')=0.63

46/14. Hoped this helped!
The answer is: "39 points" .
_______________________________________________________
Explanation:
_______________________________________________________
" x/ 50 = 78/100 " ; in which "x" equals the number of points needed.
_______________________________________________________
To solve for "x" ;
_______________________________________________________
Look at the denominators: 50 * (what value?) = 100.
→ "100 ÷ 50 = 2" .
→ So; "50 * 2 = 100" ;
So, let us look at the numerators:
x * 2 = 78 ;
↔ 2x = 72 ;
Divide each side of the equation by "2" ; to isolate "x" on one side of the equation ; and to solve for "x" ;
_____________________________________________
→ 78 ÷ 2 = 39 ;
The answer is: "39 points" .

Answer:
<h2>18/√3ft</h2>
Step-by-step explanation:
This is a ratio problem
Step one:
Given the ratio of length:width is <em> "3 space colon space square root of 3"</em>
mathematically it is expressed as
length:width 3:√3 or 3/√3
Step two:
3:√3 or 3/√3
if the built TV has a width of 6ft let the length be x
3/√3=x/6
cross multiply we have
x√3=3*6
x√3=18
x=18/√3ft
therefore the length will be 18/√3ft
