Step-by-step explanation:
x and y are roughly in a linear relationship. 
when x increases by 2 units, then also y increases by more or less 2 units.
when x increases by 3 units, then also y increases by more or less 3 units.
it is not precise, but a good approximation model.
 
        
             
        
        
        
Answer:
C:12
Step-by-step explanation:
should be 13.5
The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set. 
so the middle number of 10,11,12,15,17,19 is 13.5   since 12+15=27/2=13.5
the closest answer choice is C! Hope this helped!
 
        
                    
             
        
        
        
Answer:
6/5 or 1.2
Step-by-step explanation:
you can solve with an equation:
x : 5 = 12 : 50
x = 5 * 12 : 50 
x = 6/5 (or 1.2)
or you can solve with an expression
12/50 * 5 = 6/5 (or 1.2)
