6.5 (a) Indicate how the "Hard and Soft Acids and Bases" principle can make useful predictions in relation to stabilities of complexes. (b) Given that Sc$^{3+}$ is a "hard" cation, would you expect its complexes with carboxylate ligands to be more or less stable than its bromide complex ? (c) Given that LLL is a "soft" ligand, such as a trithiamacrocycle, what order of stabilities would you expect for its complexes M(LLL)$_2$$^{2+}$ with M = Ca$^{2+}$, Cu$^{2+}$ Cd$^{2+}$?

Calculate the probability that exactly 5 out of the 25 randomly sampled customers are satisfied with their cell phone coverage. Hint: That means show FOUR things: 1) Define/declare/state your random variable 2) Show the equation you use 3) Show how you plug in 4) Show your final answer, rounded to 4 decimal places. You may use Excel to check your work, but do not include any Excel content here. This question relies on Module 6 content. Declare/define/state your random variable: Show the equation you use: Show how you plug in: Show your final answer, rounded to 4 decimal places: b) [1 mark] Why is the probability that exactly 5 out of the 25 randomly sampled customers are satisfied with their cell phone coverage different from 20%? Please answer in at most three sentences. Hint: Think about the difference between a sample proportion and a population proportion.

Five years ago, Jaguar Manufacturing installed production machinery that had a first cost of \$25,000. At that time, initial yearly costs were estimated at \$3,000, increasing by 10\% each year. The market value of this machinery each year would be 70\% of the previous year's value. There is a new machine available now that has a first cost of \$26,800 and no yearly costs over its 5-year minimum cost life. If Jaguar uses an 8\% before-tax MARR, when, if at all, should Jaguar replace the existing machinery with the new unit? Why? (30 points)
