Answer:
The mean would be 14.4 hours. 
Step-by-step explanation:
In order to find the mean, or average, of the numbers, you would add all the numbers together.
17 + 15 +14 + 14 + 12 which equals 72
Then, you take the total which is 72, and divide it by how many numbers you added together which is 5.
72/5 = 14.4
 
        
                    
             
        
        
        
Answer:
3x-11
Step-by-step explanation:
 f (x) = 3x - 5
f(x-2)
Replace x in the function with x-2
 f (x-2) = 3(x-2) - 5
            =3x-6 -5
            =3x-11
