Problem 5-8 points. This question is about the transpose. Explain why each statement is true with a short general argument (giving a specific numerical example is not a general argument): (a) If A is an invertible matrix, then (A-I)T (AT)-1, (b) If A is any m × n nnatrix, the products ATA and AAT are symmetric matrices. Problem 5-8 points. This question is about the transpose. Explain why each statement is true with a short general argument (giving a specific...
Decide whether each statement is true or false and explain your reasoning. Give a counter-example for false statements. The matrices A and B are n x n. a. The equation Ax b must have at least one solution for all b e R". b. IfAx-0 has only the trivial solution, then A is row equivalent to the n x p, identity matrix. c. If A is invertible, then the columns of A-1 are linearly independent. d. If A is invertible,...
Explain why the claim is true or demonstrate that it is false with a counter example 3. A linear transformation T : R3 → R3 is volume-presemng if for any solid shape S in R. (for example, S could be a cube), its image T S] has the same volume as S. For any matrix M, let TM be the linear transformation corresponding to the matrix M. ·Claim: If det(A) 1, then TA s volume-preserving. Claim: If TA is volume-preserving,...

The following variables were collected: - Employee Type: Employees are either current or former. - Department: Employees either work in sales or in the warehouse. - Rating: The employee's most recent performance rating out...
2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
