The mean is 7.5 you add up all the numbers and then divide by the amount of numbers there is
        
             
        
        
        
Hey there,
It take 45 min to complete 75% of the wall
1% = 45 / 75
      = 0.6
100 % = 0.6 x 100
           = 60 min
It takes her 60 mins or 1 hour to finish building the wall.
Hope this helps :))

Answer:
x = 4
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below 
P.s: I used the Law of Sines, but there are many other ways to solve it 
 
        
             
        
        
        
Direct variation mean x =ky so y = x/k
(2,14) mean y = kx so 14 = k*2 so 14 = 7*2 so 14 = 14 
(4,28) mean y = kx so 28 = k*4 so 28 = 7*4 so 28 = 28
from these result that the 3rd choice is right sure
