Appreciate! This should be done from probability theory.

Solve problem 2 using the priblem 1 . Question is taken from Ring theory dealing with ideals and generating sets for ideals. Problem 1. Suppose that R (R,+ Jis a commutative ring with unity, and suppose F- (a,,. , a } is a finite nonempty subset of R. Modify your proof for Problem 5 above to show that 7n j-1 Problem 2. Consider the set Zo of integer sequences introduced in Homework Problem 6 of Investigation 16. You showed that...
advanced linear algebra, need full proof thanks Let V be an inner product space (real or complex, possibly infinite-dimensional). Let {v1, . . . , vn} be an orthonormal set of vectors. 4. Let V be an inner product space (real or complex, possibly infinite-dimensional. Let [vi,..., Vn) be an orthonormal set of vectors. a) Show that 1 (b) Show that for every x e V, with equality holding if and only if x spanfvi,..., vn) (c) Consider the space...
Please note n's are superscripted. (a) Use mathematical induction to prove that 2n+1 + 3n+1 ≤ 2 · 4n for all integers n ≥ 3. (b) Let f(n) = 2n+1 + 3n+1 and g(n) = 4n. Using the inequality from part (a) prove that f(n) = O(g(n)). You need to give a rigorous proof derived directly from the definition of O-notation, without using any theorems from class. (First, give a complete statement of the definition. Next, show how f(n) =...
Please answer in the style of a formal proof and thoroughly reference any theorems, lemmas or corollaries utilized. BUC stands for bounded uniformly continuous Let (X, d) be a metric space. Show that the set V of Lipschitz continu- ous bounded functions from X to R is a dense linear subspace of BUC(X, R). Since, in general, V #BUC(X, R), V is not a closed subset of BUC(X, R). Hint: For f EBUC(X, R) define the sequence (fr) by fn(x)...
Please show work :) Will upvote/rate! 4. Expectation of Product of Random Variables Proof From the definition of the expected value, the expected value of the product of two random variables is ı r P(X Y r2) E(X- Y) ri r2 where the sum is over all possible values of rı and r2 that the variable X and Y can take on (a) Using the definition above formally prove that if the events X = r1 and Y = r2...
Please do exercise 129: Exercise 128: Define r:N + N by r(n) = next(next(n)). Let f:N → N be the unique function that satisfies f(0) = 2 and f(next(n)) =r(f(n)) for all n E N. 102 1. Prove that f(3) = 8. 2. Prove that 2 <f(n) for all n E N. Exercise 129: Define r and f as in Exercise 128. Assume that x + y. Define r' = {(x,y),(y,x)}. Let g:N + {x,y} be the unique function that...
Real Analysis II (Please do this only if you are sure) ********************** *********************** I am also providing the convex set definition And key details from my book which surely helps 11. Show that K is a convex set by directly applying the definition. Sketch K in the cases n= 1, 2, 3. is a basis for E. This is the n-parallelepiped spanned by vı, vertex 1% with 0 as a Definition.

Could you please give detailed steps? Thanks! Consider a random sample from the Poisson(0) distribution (e.g. this setup could apply to the number of arrests example from class) You may take it as given that if X ~Poisson(0) then E[X_ θ)41-30" +θ (rememeber this is this is the 4th central moment or one of the definitions of kuutosis 3- (this is another commonly used definition of the kurtosis) (no need to show any of these) a. You wish to estimate...
a). Provide a DFA M such that L(M) = D, and provide an English explanation of how it works (that is, what each state represents): b). Prove (by induction on the length of the input string) that your DFA accepts the correct inputs (and only the correct inputs). Hint : your explanation in part a) should provide the precise statements that you need to show by induction. For example, you could show by induction on |w| that E2 = {[:],...
