Answer:
B. 2nd Table
Step-by-step explanation:
 
        
                    
             
        
        
        
4:2 because it goes cars then buses
        
             
        
        
        
Multiply 4 by 10%.
10% ⇒ 0.1
4 × 0.1 = 0.4
Subtract 0.4 from 4.
4 - 0.4 = 3.6 (price with discount)
Multiply 3.6 by 6%.
6% ⇒ 0.06
3.6 × 0.06 = 0.216
Add 0.216 to 3.6.
0.216 + 3.6 = 3.816
Round 3.816 to the hundredths.
3.816 ⇒ 3.82 (price with tax)
The new price of toothbrushes is $3.82.
        
             
        
        
        
Answer:
Probability of getting at least 9 out of 18 correctly is 0.0043
Step-by-step explanation:
We have 
n = 18 
p = 1/5 for correct answer
q = 4/5 for wrong answer
P( 9  X
 X  18) = 1 - P(0
 18) = 1 - P(0  X
 X 8)
 8) 
                        = 1 -  0.9957
                          =0.0043
