Answer:
11 units
Step-by-step explanation:
To calculate CD use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(- 4, 6) and (x₂, y₂ ) = D(- 4, - 5)
CD = 
      = 
      =  =
 =  = 11
 = 11
 
        
                    
             
        
        
        
Answer:
The range of data is 9
Step-by-step explanation:
We know that 
range of data = maximum value of data - minimum value of data 
Now, we can find maximum value of data 
and minimum value of data 
so, 
maximum value of data =9
minimum value of data =0
now, we can plug these values
and we get 
range of data =9-0
range of data =9
