6.2.24 Justify each Assume all vectors are in R. Mark each statement True or False. Justify each answer a. Not every orthogonal set in Rn is linearly independent. O A. False. Orthogonal sets must be linearly independent in order to be orthogonal. O B. True. Every orthogonal set of nonzero vectors is linearly independent, but not every orthogonal set is linearly independent. O C. False. Every orthogonal set of nonzero vectors is linearly independent and zero vectors cannot exist in...

Mark each statement as True or False and justify your answer. a) The columns of a matrix A are linearly independent, if the equation Ax = 0 has the trivial solution. b) If vi, i = 1, ...,5, are in RS and V3 = 0, then {V1, V2, V3, V4, Vs} is linearly dependent. c) If vi, i = 1, 2, 3, are in R3, and if v3 is not a linear combination of vi and v2, then {V1, V2,...
9. [10 points (A) True or False. Circle your answer and justify it by showing your wot (a) T F: Let A be any square matrix, t (b) T F: If S is invertible, then ST is also invertible. hen AT A, AAT, and A+ AT are all symmetric. If a row exchange is required to reduce matrix A into upper triangular form U then A can not be factored as A-LU (d) T F Suppose A reduces to upper...
Mark each of the following as true or false and justify your response. True or False & explain reason for true or false: 1. Sample statistics for variables in a data set should only be calculated for a case-control study. 2. Results from studies should always be generalized to the entire population regardless of the sample. 3. Stratified analyses may reveal differences between groups. 4. Relative Risk (RR) may be calculated for retrospective and prospective studies. 5. If a variable...
2. Determine each of the following statement is true or false and justify your answer: (a) S has a subgroup of order 15. (b) S5 has a subgroup of order 40 2. Determine each of the following statement is true or false and justify your answer: (a) S has a subgroup of order 15. (b) S5 has a subgroup of order 40
Let A and B be nxn matrices. Mark each statement true or false. Justify each answer. Complete parts (a) through (d) below. a. The determinant of A is the product of the diagonal entries in A. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The statement is false because the determinant of the 2x2 matrix A = is not equal to the product of the entries on the main...
linear algebra question easy, please answer fast with steps Mark each statement True or False. Justify each answer. Here A is an mxn matrix. Complete parts (a) through (e) below a. If B is a basis for a subspace H, then each vector in H can be wrben in only one way as a linear combination of the vectors in B. Choose the correct answer below O A. The statement is false. Bases for a subspace H may be linear...
