Consider the following simple logistics problem, which you will solve: An airline cargo company has 1 aeroplane which it flies from the UK to the US on a daily basis to transport some cargo. In advance of a flight, it receives bids for deliveries from (many) customers. Customers state the weight of the cargo item they would like delivered, and the amount they are prepared to pay. The airline is constrained by the total amount of weight the plane is allowed to carry. The company must choose a subset of the packages (bids) to carry in order to make the maximum possible profit, given the weight limit that they must respect. In mathematical form the problem is: Given a set of N items each with weight wi and value vi, for i=1 to N, choose a subset of items…Language C++ It has been observed by management that some faculty member at the university demonstrates a lackadaisical attitude toward teaching. They seldom go to class yet at the end of each month they receive full salary. Management has decided that GHs 200, 300, 400, and 500 will be deducted from a faculty’s salary if he/she offends once, twice, third time and forth time respectively in a month. This means that if a faculty member offends once in a month GHs 200 will be deducted, if a faculty member offends twice in a month, GHs 500 (i.e. 200+300) will be deducted, if a faculty member offends three times in a month GHs 900 (i.e. 200+300+400), will be deducted and if a faculty member offends four times in a month GHs 1,400 (i.e. 200+300+400+500). Assuming all faculty members are on a flat salary rate of GHs 2000. a. Write a program to request for the names of four faculty members and number times he/she has absented him/herself from class.

- library contains books, periodicals, and DVDs (no items of other types are available and a given item belongs to only a single category). All these items can be used by the user of the library. Some of the items (books, periodicals, and DVDs) are only reference items, and others can be borrowed by the users. There are two types of users; registered users and temporary users. While registered users can borrow up to 100 items, the temporary users can borrow only 2 items at a time. In the initial work of the EER modeling, your teammates have identified Item, User, and ItemCopy as entities. Which of the following statements are correct about a possible EER model for this set of requirements?
