Answer:
Step-by-step explanation:
Let X be the number of tickets issued by a meter reader for parking-meterviolations can be modeled by a Poisson process with a rateparameter of five per hour.
X is Poisson with parameter =5per hour
a) the probabilitythat exactly three tickets are given out during a particular hour
=
b) the probabilitythat at least three tickets are given out during a particularhour
=
c) tickets we expect to be given during a 45-min period
=
Note: Poisson distribution is
Answer:
Kadeem will take 0.166 h more to complete the course.
Step-by-step explanation:
The speed is the rate at which the distance changes, when the speed goes up the distance changes more quickly, therefore if the distance is the same and the speed is higher the one who will take longer is the one that has less speed. In this case the one who will take longer to drive the 25 miles is Kadeem, since he's driving at 50 mph. In order to calculate how much longer we need to calculate the time at which each of them complete the course, this is shown below:
time = distance/speed
For Kadeem:
time = 25/50 = 0.5 h
For Quinn:
time = 25/75 = 0.334 h
The difference between the is 0.5 - 0.334 = 0.166 h.
Answer: c
Step-by-step explanation:
Based on the percent breakdown of 360%.
100% 100% 100% 20%20%20%
15. 15. 15. 3. 3. 3.
100% is all of it, so 15. This is x.
20% of it would be calculated as 0.2 x 15 or 3. This is y.
