Answer:
Step-by-step explanation:
Given that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"†).
a) 
b) 
c) 
d) 2 std dev = 2(20) =40
Hence 2 std deviation means
20-40, 20+40
i.e. (0,60)

Answer:
she would save 1.1 extra gallons 
Step-by-step explanation:
54 miles to work 
30 miles a gallon so 1.8 gallons to get to work 
27 miles a gallon so 2 gallons to get to work 
30 miles car saves 5.4 miles more each day she drives to work 
5.4 X  5 = 27 extra miles so 1.1 gallons she would be saving each work week 
 
        
             
        
        
        
<em>n</em> must be 0, since <em>x </em>ⁿ = 1 for all positive, real <em>x</em> if <em>n</em> = 0. So the answer is A.
 
        
             
        
        
        
We find the base of the rectangles by taking the difference between the interval endpoints, and dividing by 2.
Base of rectangle = (6 - 2) / 2
 = 2
The area of the first rectangle:
(4 - 2)f(4) = 2[4 + cos(4π)]
The area the second triangle:
(6 - 4)f(6) = 2[6 + cos(6π)]
Now just compute the two areas and combined them. That will give you the estimated under the curve.
To evaluate the midpoint of each rectangle, we take the midpoint of the base lengths of each rectangle. This midpoint is the x value. Then evaluate the function at that x value.
The midpoint of the first rectangle is x=3. Evaluate f(3).
The midpoint of the second rectangle is x=5. Evaluate f(5).
