Answer:

Step-by-step explanation:
Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;
5 x 4 = 20
If a color is selected at random the probability would be 

our part is 5
our whole is 20
so the probability would be;
 or
 or  when reduced
 when reduced

Answer:
it would be D
Step-by-step explanation:
all other choices have a repeating x value. 
 
        
             
        
        
        
Firstly, the rate of increase of Canton = 80/7720 = 0.010
The rate of increase of HP = 120/3200 = 0.0375
Apply  the formula of compound interest==> A =A'(1+i)^n
The population will be equal when the following equality is satisfied
7720(1+0.01)^n = 3200(1+0.0375)^n 
or
7720x1.01^n = 3200x1.0375^n
Divide both sides by 3200 ===>(193/80)x1.01^n=1.0375^n
        
                    
             
        
        
        
Answer: A
Step-by-step explanation:
X=(2±√4-12)/2
X=(2±2i√2)/2
x1=1+i√2
x2=1-i√2
