Textbook Question
Chapter 1, Problem 25SE
Living with AIDS The table gives the number of people diagnosed with AIDS/HIV in 2010 in the five states with the largest number of cases, as well as the District of Columbia, as reported by the U.S. Centers for Disease Control and Prevention (CDC). It also shows the population of those regions at that time from the U.S. Census Bureau. Find the number of people diagnosed with AIDS/HIV per thousand residents in each region, and rank the six regions from highest rate (rank 1) to lowest rate (rank 6). Compare these ranking (of rates) with the ranks of total number of cases. If you moved to one of these regions and met 50 random people, in which region would you be most likely to meet at least one person diagnosed with HIV? In which of these regions would you be least likely to meet at least one person with HIV? See page 34 for guidance.

(i) Prove that if G is triangle free (no induced K3) then m(G) ≤ a(G)B(G). Hints - The neighborhood of a vertex in a triangle free graph must be independent; all edges have at least one end in a vertex cover. (ii) Show that all graphs of order n ≥ 3 and size m> [n2/4] contain a triangle. Hints - you may need to use either elementary calculus or the arithmetic-geometric mean inequality.arrow_forwardWe consider the one-period model studied in class as an example. Namely, we assumethat the current stock price is S0 = 10. At time T, the stock has either moved up toSt = 12 (with probability p = 0.6) or down towards St = 8 (with probability 1−p = 0.4).We consider a call option on this stock with maturity T and strike price K = 10. Theinterest rate on the money market is zero.As in class, we assume that you, as a customer, are willing to buy the call option on100 shares of stock for $120. The investor, who sold you the option, can adopt one of thefollowing strategies: Strategy 1: (seen in class) Buy 50 shares of stock and borrow $380. Strategy 2: Buy 55 shares of stock and borrow $430. Strategy 3: Buy 60 shares of stock and borrow $480. Strategy 4: Buy 40 shares of stock and borrow $280.(a) For each of strategies 2-4, describe the value of the investor’s portfolio at time 0,and at time T for each possible movement of the stock.(b) For each of strategies 2-4, does the investor have…arrow_forward
