Answer:
The probability of the tip to be more than 200 is 0.1.
Step-by-step explanation:
As per the given data 
Amount of tip            Number
      0-20                       200
    20-50                       100
    50-100                      75
  100-200                     75
     200+                        50
____________________
Total=                         500
So what is the probability of tip to be more than 200 is given as 

From the table the value is 50 for the tip to be more than 200 where as the total occurrences are 500 so substituting values:

So the probability of the tip to be more than 200 is 0.1.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
1) if according to the condition a₁=3 and r=2/3, then a₁₀ can be calculated as:
a₁₀=a₁*r⁹;
2) according  to the rule above:
a₁₀=3*(2/3)⁹=512*3/(6561*3)=512/6561.
 
        
             
        
        
        
Answer: x = 6
Step-by-step explanation: If you take 88.56 + 5x = 19.76x, an equation, you should first rearrange the variables to the left side of the equation: 5x - 19.76x = -88.56. 
Next, you should combine your like terms. So, -14.76 = -88.56.
Then, divide both sides of the equation by the coefficient of variable. So, x = -88.56 / -14.76./
Lastly, calculate. Determine the sign for multiplication or division, so x = 88.56 / 14.76. Multiply both the numerator and denominator with the same integer. So, x = 8856 / 1476. Cross out the common factor, then you get your answer of x = 6
