Use JAVA
Program #1: Hotel Occupancy: Write a program that calculates the occupancy rate for a hotel. The program should start by asking the user how many floors the hotel has. A for loop should then iterate once for each floor. In each iteration of the for loop, the program should ask the user for the number of rooms of the floor and how many of them are occupied. After all of the iterations are complete the program should display how many rooms the hotel has, how many of them are occupied, and the percentage of rooms that are occupied.
It is traditional that most hotels do not have a 13thfloor. The for loop in this program should skip the entire thirteenth loop iteration.
Input validation: Do not accept a value of less than one for the number of floors. Do not accept a value of less than 10 for the number of rooms on a floor. Do not accept a value for occupied that is greater than rooms.
EXAMPLE INPUT TO USE FOR TESTING (just an example your program should work for all different inputs):
If the Number of Floors in the Hotel: 16
And the user to INPUT the following information for total rooms and occupied rooms:
Floor # | Total Rooms | Occupied Rooms |
1 | 200 | 180 |
2 | 170 | 100 |
3 | 50 | 20 |
4 | 125 | 125 |
5 | 100 | 80 |
6 | 200 | 80 |
7 | 80 | 40 |
8 | 90 | 45 |
9 | 95 | 0 |
10 | 115 | 103 |
11 | 125 | 17 |
12 | 140 | 128 |
14 | 130 | 129 |
15 | 100 | 99 |
16 | 60 | 24 |
The output of your program for the above example should be (do NOT print the above chart!):
The Hotel has 1780 Total Rooms.
1170 of the Rooms are Occupied.
66 % of the Rooms are Occupied.
Program #2: Pennies: For the first day worked a person earns $1.00 for the entire day. For the second day worked the person’s daily pay is doubled to $2.00. For the third day worked the person’s daily pay is doubled again to $4.00. For each consecutive day a person works their daily pay is doubled in this way.
Write a program that asks a user to enter the number of days they worked and then calculates the pay they earned for each day along with the total pay they earned for all of the days. The program output should be the pay for each day and the total pay earned for all the days.
Input Validation: Do not let the user enter a number of days that is less than 1. Use a loop to prompt them to enter another number for the number of days if they enter a number that is less than 1.
Make sure and format your output.
Example: This would be the output for a person who worked 4 days
Pay for Day 1: $1.00
Pay for Day 2: $2.00
Pay for Day 3: $4.00
Pay for Day 4: $8.00
TOTAL PAY FOR 4 DAYS: $15.00

Case – Recreational Park Project
The public has recognized the benefits of recreation and parks as
essential to their health and quality of life. A recent survey
conducted in 2016 found that the construction of more recreational
facilities was a top priority among residents in Lazarette Town (in
the Caribbean).
As such, the town council in Lazarette, with the help of other key
stakeholders, has sourced and secured three (3) million dollars of
grant funds from the Caribbean Wellness Community (CWC) for the
development of a mini outdoor recreational park on three (3) acres
of land donated by a benevolent resident of the town.
The park will contain sporting facilities among other recreational
facilities (e.g. walking trails, children playground, tennis court,
basketball court, work out stations, benches, shower facilities,
rest rooms etc.). All major key stakeholders and sponsors have
unanimously agreed that that the facility should cater for
residents of all ages. Additionally, a group of minority
stakeholders has expressed their requirements of having an
eco-friendly and climate resilient facility. The park should be
completed and ready for use by 2022, i.e. the project duration
should not exceed two years.
To ensure that the project is completed on time, within scope and
on budget, the funding agency and the Lazarette Town Council
require that a dedicated and knowledgeable project team is assigned
to the project. CWC has expressed the need for the project
deliverables to be of ‘high’ quality to guarantee stakeholders’
satisfaction and safety. The CWC requires that ‘tight’ procurement
processes should be followed to ensure transparency, accountability
and economy. It is anticipated that most of the goods, works and
services for building the park will be procured from vendors,
suppliers and contractors in the town. In addition, CWC has
detailed the need for both positive and negative projects risk to
be properly managed throughout the project.
In response to CWC implied and expressed requirements, the
Lazarette Town Council has selected and appointed your team to
provide project management services for the Recreational Park
Project. As a proactive team, your team has decided to use ‘best
practices’ in project management to plan project activities and get
approval from key project stakeholders before constructing or
building the facility. Give the type and nature of the project, the
intention is to use a traditional/waterfall approach to project
management activities instead of the largely popular and
contemporary agile methodology used other industries.
Your team understands the value of planning before doing, and the
council’s concerns of not losing the grant funding from CWC. In
addition, your team is keen on building a good reputation in
the
town. With a can do attitude and the need to increase the chances
of the project success, the project management team (your 5-member
group) is determined to ensure that the team utilizes the ‘best
practices’ for planning, executing and controlling this valuable
community based project.

Covid-19 started a derived demand, for instance, the high demand for hand sanitizer led to the derived demand of the isopropyl alcohol market .
What are some other covid- 19 derived demand, beside facemask ?
Definition of "Derived Demand"
Derived demand is a term in economics that describes the demand for a certain good or service resulting from a demand for related, necessary goods or services. For example, the demand for large-screen televisions creates a derived demand for home theater products such as audio speakers, amplifiers, and installation services.

A person with a cough is a persona non grata on airplanes, elevators, or at the theater. In theaters especially, the irritation level rises with each muffled explosion. According to Dr. Brian Carlin, a Pittsburgh pulmonologist, in any large audience you'll hear about 18 coughs per minute.
(b) Find the probability of four or fewer coughs (in a large auditorium) in a 1-minute period. (Use 4 decimal places.)
(c) Find the probability of at least eight coughs (in a large auditorium) in a 32-second period. (Use 4 decimal places.)
