Let
x-------> the number of persons in the family
f(x)------> the function represent the cost of living
we know that
The domain of the function  would only include positive integers, because the number of persons can not be negative or a fraction
The range of the function would only include positive numbers, because the cost can not be negative
therefore
<u>the answer is the option B</u>
The domain would only include positive integers.
 
        
                    
             
        
        
        
Answer:
   class assignment seems to discriminate against Art Club members
Step-by-step explanation:
The probability of getting the requested assignment given that the student was in Art Club was ...
   P(got class | art club) = P(got class & art club)/P(art club)
   P(got class | art club) = (100/500)/(165/500) ≈ 60.6%
__
   P(got class | not club) = P(got class & not club)/P(not club)
   P(got class | not club) = (265/500)/(335/500) ≈ 79.1%
It looks like George's theory may be incorrect, as a significantly greater percentage of non-club students got their requested class than did club students. The class assignment process and art club membership are not independent, suggesting an unfair disadvantage for club students.
 
        
             
        
        
        
Answer:
n = 4
Step-by-step explanation:
3 + 4n + n = 2n +15
3 + 5n = 2n + 15
5n - 2n = 15 - 3
3n = 12
n = 12 / 3
   = <u>4</u>
