After that, you are to evaluate the playgrounds you have been to before if that is safe for any children to play around.The CIS Department at Tiny College maintains the Free Access to Current Technology (FACT) library of ebooks. FACT is a collection of current technology ebooks for use by faculty and students. Agreements with the publishers allow patrons to electronically check out a book, which gives them exclusive access to the book online through the FACT website, but only one patron at a time can have access to a book. A book must have at least one author but can have many. An author must have written at least one book to be included in the system but may have written many. A book may have never been checked out but can be checked out many times by the same patron or different patrons over time. Because all faculty and staff in the department are given accounts at the online library, a patron may have never checked out a book or they may have checked out many books over time. To simplify determining which patron currently has a given book checked out, a redundant relationship between BOOK and PATRON…create a Causal Loop Diagram (CLD) explaining the cause-effect relationships for COVID-19.

- Imagine you are an avid movie goer and you prepared a list of n movies you are considering watching. As a thorough researcher, you prepared a list of k friends, whose movie advice you trust. For each movie, you are debating whether to either see it or speak to all of your friends and hear their recommendations. A more efficient approach is to choose between watching the movie and speaking with at least one trusted movie recommender friend. This approach will take a total of t hours. Prove that the problem is NP-hard.Q3 Measurements on call-failures in a Telephone Central Office (TCO) compiled over eight bimonthly data, i = 1, 2, ..., 6 indicate random values (RVS) with corresponding frequency of occurrence (n.).
