Answer:
 
   
Step-by-step explanation:
It is given that a meteorologist is using a Doppler radar to find out the distance of the storm as it passes using a polar grid.
The origin of the radar screen is its center.
And the distance between each ring is 10 miles from the center.
So let :
r = radius 
h and k = be the coordinates of the center.
So the equation of a circle is :

Now the equation of the fourth circle when the radius changes by 10 miles is :
 
   
 
        
             
        
        
        
The first thing we must do for this case is to observe the highest relative frequency of the table in the total column.
 For the white car we have:
 Male = 0.11
 Female = 0.20
 Total = 0.31
 The percentage is given by:
 (0.31) * (100) = 31%
 Answer:
 The percentage that represents the car bought most often is:
 31%
        
             
        
        
        
Answer:
   8.8 inches
Step-by-step explanation:
Since the level is proportional to the time, when the time increases from 5 to 11 (by a factor of 11/5), we expect the water level to increase by a factor of 11/5 to ...
    (4 in) · 11/5 = 44/5 in = 8 4/5 in
