Prove that transitivity implies each of the following claims: . If a ~ b andb ~~ c, then a c. bc, then da (Harder) If a - bandb~c, then a c. In each case, first convert the strict/indifferent statement to an equivalent statement using only weak preference. Then prove the equivalent statement using our definition of transitivity, which involves only weak preference.
1. "Au (TI/2 = 64.8 hr) can be produced by bombarding stable 197 Au with neutrons in a nuclear reactor. Suppose that a Au foil weighing 0.1 g is placed in a certain reactor for 1 2 hrs and that its activity is 0.90 Ci when removed. (a) What is the theoretical maximum activity due to "Au in the foil? (b) How long does it take for the activity to reach 80% of the maximum?
