Math ConceptBook :Textbook: Mathematical Excursions, Fourth Edition by Aufmann, Lockwood, Nation,and CleggAnswer all the12 question for echo section : 1. List all subsets of the set {3, R, k}.2. The set {x | x is an odd integer between -6 and 8}has how many subsets? Answer this question with a methodof reasonable time and labor. Write a little bit of work.3. For the sets A = {2, 4, 6}B = {1, 2, 4, 7} and universal set U = {1, 2, 3, 4, 5, 6, 7, 8},find the sets (a) A union B and (b) A intersect B’. Notethe apostrophe on B in part (b),Q1 to 3 “this part doesn’t mention any section”.4. For sets A, B, C, and universal set U given by the following:A = {1, 3, 6, 7}; B = {2, 3, 7, 8}; C = {5, 6, 8}; U = {1, 2, 3, 4, 5, 6, 7, 8},find the set A’ intersect (B union C) and write it fully in roster form.Show some work; this is not a short-answer problem.5. Draw a Venn diagram to represent the set A’ intersect B.6. For each statement below, write the negation of the statement fully in words.(a) The lunch was served at noon.negation: __________________________________________________________(b) The game was not shown on ABC.negation: __________________________________________________________Q4 to 6 “this part for this section: 2.3, 3.1, and maybe a small part of 3.2”.7. Write the conditional statement below in its equivalentdisjunctive form: If she could sing, she would be perfect for the part.equivalent disjunctive form of the above conditional:8. Write (a) converse; (b) inverse; and (c) contrapositive of the conditional statement below fully in words.If you are the U. S. president, then your age is at least 35.(a) converse: ____________________________________________________________(b) inverse: ____________________________________________________________(c) contrapositive: ____________________________________________________9. Calculate the simple interest on a nine-month loan of $6,000if the interest rate is 4.5%.Q7 to 9 “this part covered section 2.4, 3.3, 3.4 and 11.1”.10. What is the simple interest on a two-month loan of$800 if the interest rate is 1.5% per month?11. For a simple-interest six-month loan of $8500, what isthe maturity value if the simple interest is 6.8%?12. Use the compound amount formula to calculate thecompound amount A for P = $3500, t = 14 years, and r = 8%compounded semiannually. Write enough work. Your calculatorwill help with the computation, but you still need to write enough work.Q10 to 12 “this part covered section 11.1, 11.2”
