For each of the following relations, determine whether it is reflexive, anti-reflexive, symmetric, anti-symmetric, or transitive. Briefly explain your answers for each one. (a) (2 points) The domain is all CPUs. For any CPUs x and y, xRy if x has at least as many cores as y. (b) (2 points) The domain is all people. For any people x and y, xRy if x and y are friends. Assume that everyone is his/her own friend, and that if A...

Python 3 Discrete Mathematics We are going to write a program to read in relations, show the matrix of the relation. We will also show if the relation is reflexive, symmetric, anti-symmetric and transitive. This program will read in files that the user gives. Normal Error handling applies. The file the user gives you will have the elements of the set for the relation followed by the tuples in the relation. The Text Files The first line of the text...

Please answer all fill in the blanks, thanks!
In the United States, tire tread depth is measured in 32nds of an inch. Car tires typically start out with 10/32 to 11/32 of an inch of tread depth. In most states, a tire is legally worn out when its tread depth reaches 2/32 of an inch. A random sample of four tires provides the following data on mileage and tread depth: Mileage (10,000 miles) Tread Depth (32nds of an inch) Tire...
