Answer:
Step-by-step explanation:
The standard form equation of a circle is ...
   (x -h)^2 +(y -k)^2 = r^2 . . . . . . . . . center at (h, k), radius r
Divide your given equation by 2 to put it into standard form:
   (x +3)^2 +y^2 = 16
Comparing to the above, we see ...
The center point of the circle is (-3, 0); the radius is 4 units long.
 
        
             
        
        
        
 For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
 Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
