Answer:
5
Step-by-step explanation:
We are given that a soccer team has played = 25 games
The team won the games =60% of games that has played
We have to find the minimum number of additional games the team must win in order to finish the season winning 80% of the games it has played.
60% of the games=
A soccer team won games that has played =15
if the team won 80% of the games
Then,80% of 25= games
Number of games added to win 80% of the games =20-15=5
Hence, the minimum number of additional games that the team must win 80 % of the games it has played=5

Option D:
The set is {-2, -1, 0, 1, 2, 3, 4}.
Solution:
Given set:
Z means integer values.
Integer means set of positive and negative values including zero.
This means x lies between -2 and 4.
- If x strictly less than -2 and greater than 4 means you don't have to include -2 and 4.
- But here x less than or equal to -2 and greater than or equal to 4, so you have to include -2 and 4.
The integers are -2, -1, 0, 1, 2, 3 and 4.
So, x belongs to the set {-2, -1, 0, 1, 2, 3, 4}
Hence the given set is defined by the set {-2, -1, 0, 1, 2, 3, 4}.
Option D is the correct answer.
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.
- P(T)=0.38
- P(T')=0.63
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
