tthese two are related (5 points.) Since A) is a set, we can inquire, for each element x of S, whether x is an element of R) We define the set N to be the set of all elements of S for which the statement "x is an element of Ax)" is NOT true: N = {x: x is an element of S and x is NOT an element of Ax)}. Explain why N is an element of P(S). This...
2. Given the set S-ta,b,c,d,e,f,g,h) a) How many subsets does S have? b) How many subsets have exactly 5 elements? c) A subset is randomly chosen for the collection of all possible a) b) c) subsets. What is the probability that it contains exactly 3 elements? d) A subset is chosen at random from all the subsets. d) What is the probability that it contains the element a?
please provide detail! will rate! thank you! 4. Let C be a closed, and bounded subset of IR". Suppose that 01,02, Os, is a sequence of open subsets of Rn and C u 10k.

In the project I am working right now, we have some python and some C# code. At some point, I call from python a subprocess which starts a C# executable. This C# code returns an error code, which has to be understood on the python side and a readable report has to be created. This means, both sides "must speak the same language". So, at the end I have to handle a mapping {error codes: readable explanation} (normally we implement...
i=1 For en The purpose of this problem is to show that there exists a set whose fractal dimension does not exist. Let A be the following subset of [0,1], where we think of representing each point of [0,1] by it's base ten series expansion(s): di A={r=Č : di € {0,1,...,9} 101 and di = 0 whenever there exists n € NU{0} such that 22n <i < 22n+1 – 1}. 10-2", n=0,1,2, ..., show In N (A, €2n) 2 In...

Let G be a finite group. For each E X, consider the map (aje- fer all elements r X (b) 9-(92-2) for all 91,92 G and all r E X Show that is surjective and that, for all y...
Question 2. Recall that a monoid is a set M together with a binary op- eration (r,y) →エ. y from M × M to M, and a unit element e E/, such that: . the operation is associative: for all x, y, z E M we have (z-y): z = the unit element satisfies the left identity axiom: for all r E M we have the unit element satisfies the right identity axiom: for all a EM we Let K...
1) Up until now we have always ignored air resistance. We should now add it. Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bu. The coefficient b is a constant. (For this problem you can use calculus textbooks or wolfram alpha to do the calculus.) • What are the units on...
Suppose you have an array S indexed from 1 to n which contains n numbers, not in any particular order, and you wish to count how many times a given number x occurs in S. Consider the recursive algorithm below for this which finds the number of occurrences of x in the index range i...j in S. Of course, solving the problem would involve an initial call to the algorithm for the range 1.n: int CountOccur (int i,j) { int...
