Aliens are observing a park in new york. They notice a merry-go-round has a radius of 3.12m and a moment of inertia of 3100kgm^2 at the vertical axis through the center. The contraption has been lubricated recently so there is no friction. one of the earthlings applies a tangential force of 19N for 13s begging at rest. Unfortunaley after gathering this data the aliens computer broke so now they must calculate the work that was done over the course of the 13s.

“Marriott International announced in November 2018 that attackers had stolen data on approximately 500 million customers. The breach initially occurred on systems supporting Starwood hotel brands starting in 2014. The attackers remained in the system after Marriott acquired Starwood in 2016 and were not discovered until September 2018.”(sourced from a published report) Referring to the case given, list and explain 2 steps that can help prevent data breach like this.

C PROGRAMMING

Build a hotel management program. The user will register their name and put their check-in time and check-out time. They can choose their type of room they stay (Deluxe room, junior suite room, suite room, presidential suite room). Then, the program will determine the total price.

Exercise 5A-2 Least-Squares Regression [LO5-11]

Exercise 5A-2 Least-Squares Regression [LO5-11]

 

Bargain Rental Car offers rental cars in an off-airport location near a major tourist destination in California. Management would like to better understand the variable and fixed portions of it car washing costs. The company operates its own car wash facility in which each rental car that is returned is thoroughly cleaned before being released for rental to another customer. Management believes that the variable portion of its car washing costs relates to the number of rental returns. Accordingly, the following data have been compiled:

Month Rental Returns Car Wash Costs
January 2,400   $ 11,000  
February 2,500   $ 13,100  
March 2,700   $ 11,800  
April 3,000   $ 14,300  
May 3,600   $ 16,200  
June 5,000   $ 23,300  
July 5,500   $ 22,200  
August 5,500   $ 22,200  
September 4,700   $ 22,800  
October 4,000   $ 21,100  
November 2,200   $ 10,700  
December 2,800   $ 14,200  

 

Exercise 5A-2 Part 2

2. Using least-squares regression, estimate the variable cost per rental return and the monthly fixed cost incurred to wash cars. (Round Fixed cost to the nearest whole dollar amount and the Variable cost per unit to 2 decimal places.)

A survey conducted for the Northwestern National Life Insurance Company revealed that 70% of American workers say job stress caused frequent health problems.

A survey conducted for the Northwestern National Life Insurance Company revealed that 70% of American workers say job stress caused frequent health problems. One in three said they expected to burn out in the job in the near future. Thirty-four percent said they thought seriously about quitting their job last year because of work-place stress. Fifty-three percent said they were required to work more than 40 hours a week very often or somewhat often. a. Suppose a random sample of 10 American workers is selected.What is the probability that more than seven of them say job stress caused frequent health problems? What is the expected number of workers who say job stress caused frequent health problems? b. Suppose a random sample of 15 American workers is selected. What is the expected number of these sampled workers who say they will burn out in the near future? What is the probability that none of the workers say they will burn out in the near future? c. Suppose a sample of seven workers is selected randomly. What is the probability that all seven say they are asked very often or somewhat often to work more than 40 hours a week? If this outcome actually happened, what might you conclude?

Problem

Create a domain model for this system.

Virtual Safari is an augmented reality game similar to Pokémon Go.

A virtual jungle is populated by several kinds of agents: hunters (equipped with a smart phone containing a GPS device), monster factories, and ammo factories.

Agents have locations. These locations correspond to actual locations on a Google Map.

As a hunter moves, his location is updated. All nearby factories are displayed.

If a hunter is very near an ammo factory, he may request and receive 10 bullets (per hour) or he may purchase any number of bullets. (When this happens the hunter's account is debited.)

If a hunter is very near a monster factory, the factory waits a random time interval, spawns a monster, and then displays it to all very near hunters.

A monster has a type. The type of the monster tells the monster's name (e.g., Charmander, Squirle, Metapod) and integer value. The bigger the value, the harder it is to kill that type of monster.

Elite factories produce high-value types of monsters. They are rare and produce monsters infrequently.

A hunter can shoot a bullet at a monster. If enough bullets hit the monster, the monster is killed and added to the hunter's trophy room. The hunter's status is the sum of the values of all monsters in his trophy room.
