Please help me on this. I'm lost with the invertible matrix theorem. This learning module introduced the invertible matrix theorem. This theorem is a collection of 12 equivalent statements. This means that when one statement in the theorem is true, all statements in the theorem are true. Similarly, when one statement in the theorem is false, all statements are false. For your initial post, propose a specific n x n matrix A, where n >= 3. Select four statements from the invertible matrix theorem and show that all four statements are true or false, depending on the matrix you selected. Make sure to clearly explain and justify your work. Also, make sure to label your statements using the notation used in the notes (e.g., part (a), part (f), etc.). In responding to your classmates’ posts, verify that their work is correct and select three additional statements they did not originally address and show that these statements are true (or false). Again, make sure to show your work.

(b) In each case below, state whether the statement is true or false. Justify your answer in each case. (i) A+B is an invertible 2×2 matrix for all invertible 2×2 matrices A, B. [4 marks] (ii) If A is an n×n invertible matrix and AB is an n×n invertible matrix, then B is an n × n invertible matrix, for all natural numbers n. [4 marks] (iii) det(A) = 1 for all invertible matrices A that satisfy A = A2....
Please show all your work. I need step by step. How did you solve? Please help me both part or both question. Please help me with all question. Will give you thumbs up. Part IV – True or False Each question is worth 1 point. For each of the following statements, determine whether it is true or false (circle the answer; you don't need to show any work). 1. True or False: The rank of a square matrix equals its...

4. Here is a fact about permutations: (*) nPr= n!/(n-k)!, for all k =n. Let's prove this via mathematical induction for the fixed case k-3. 2 of 3 (i) Write clearly the statement (**) we wish to prove. Be sure your statement includes the phrase "for all n" (ii) State explicitly the assumption in (*) we will thus automatically make about k-2 (ii) Now recall that to prove by induction means to show that IfmPm!/lm-k)! is true for all km...
Hello, please help solve problem and show all work thank you. (Linear models) Suppose we have a vector of n observations Y (response), which has distribution Nn(XB.ση where x is an n × p matrix of known values (indepedent variables), which has full column rank p, and β is a p x 1 vector of unknown parameters. The least squares estimator of ß is 4. a. Determine the distribution of β. xB. Determine the distribution of Y b. Let Y...
HELLO PLEASE DO NOT SEND WORK, JUST ANSWERS THANK YOU. 1. Let A be an invertible matrix with size 10 x 10, and let v be a nonzero vector in R10. Which of the following statements is false? (a) v is in null(A) (b) v is in col(A) (c) O is not an eigenvalue of A (d) v is in row(A) 2. If a system of three linear equations in four unknowns has solution 21 = -2, 22 = 1,...

could you please help me with understanding why the answer to d) is not 3 parameters but instead 5,4 or 3? In a row echelon form, don’t we know that each non-zero rows has a leading 1 (by definition)? And so we know that the rank must be 3? 6-3=3 (by given theorem: n-r= #parameter) 4xy + 5ax2- 2ay +5x4 + 2xs 2x4+2xs 4x4 +x = 0 in ce 2x3- 9. (a) 2x, +2x- 4a x a + 2ax3 +...
Please read the directions for this question when answering! Thank you very much, I appreciate the help! 4. Fill in the blank with "all", "no", or "some" to make the following statements true.
