(b) Any two finite groups of the same order are isomorphic. (c) A permutation can be uniquely expressed as a product of transpositions. (d) Any ring with a unity must be commutative.

Question 2 please Exercise 1. Define an operation on Z by a b= a - b. Determine ife is associative or commutative. Find a right identity. Is there a left identity? What about inverses? Exercise 2. Write a multiplication table for the set A = {a,b,c,d,e} such that e is an identity element, the product is defined for all elements and each element has an inverse, but the product is NOT associative. Show by example that it is not associative....

help please and thank you 3. The symbole, also called XOR, is the logic operation modeling the exclusive OR. We will define Peas -(P Q). (a) Give a truth table that fully describes P Q. (Just like the other logic operations were defined in Lecture 3.) (b) State what it would mean for 2 to be commutative and associative, and then prove or disprove your statements. (c) Let A, B be sets. Prove that r e AAB iff (x E...
5. Prove each of the following set equalities both by Venn Diagram and by algebraic method. (a) A - (B C) = (A - B) (A - C) (b) A - (B C) = (A - B) (A - C) (c) A (B - C) = (A B) - C = (A B) - (A C) Hint: To prove the last form, use the equality A C' = A (A' C'). (d) A (B - C) = (A B) (A...
Multiple choice question The explanation for this problem will require some algebra. Consider the effects of the following changes in product prices and money income on Perry's welfare: I. A sales tax of 25 percent on goods X and Y, the only two goods in the economy. II. A 20 percent tax on income. Choosing between the two budget lines, Perry would prefer a. I b. II c. I, only if Perry's indifference curves are relatively steep with respect to...

Give two realistic examples each of behavioral and physiological adaptations a species could use to better compete with a rival species. Give the type of competition the following two examples represent and explain why. Two different hyena species are competing with each other for more time feeding at the newly killed carcass. -Lions eating gazelles that are then unable to be eaten by hyenas. Response must be between 2-3 paragraphs.
