Inflation and Money — End of Chapter Problem The cost of the average consumer's basket of goods in 2022 was nearly 12 times what it was in 1950. In other words, what the average consumer bought for $100 in 1950 would cost a consumer $1,200 in 2022. Does this mean that the purchasing power of the average consumer is one-twelfth what it was in 1950? Complete the following passage. The perception of an increase in the average cost of a basket of goods, from $100 to $1,200, reflects money illusion. To analyze the effect of inflation on purchasing power, we should focus on real, not nominal values. As prices have risen over time, so have incomes, and now, on average, purchasing power is higher than in 1950.

Problem 2: Determine the value of output O for the neural network in Figure 1 that diagnoses tool breakage on a machining center. Each neuron uses a step transfer function with the value of the threshold shown in the network. The value of each weight is shown on the corresponding connection: a. Is the tool operational or broken? b. What should be the value of Threshold $T_O$ to get a response opposite to the one in (a)? Threshold $T_1$ Threshold $T_B$ $n_1$ Force = 5 $T_{B_1} = 1.1$ 0.5 Threshold $T_O$ $T_{I_1} = 6.5$ 0.8 $n_4$ $T_{B_O} = 1.0$ 1.0 1.1 $n_2$ $n_6$ Vibration = 7 0.7 2.0 $T_{I_2} = 4.0$ $n_5$ 2.2 3.0 $n_3$ $T_{B_2} = 1.5$ Temperture = 6 $T_{I_3} = 2.2$ Figure 1.

myMovies.dat War of the Worlds, Byron Haskin, 88, 01/01/1953, 01/01/2000, 15000000.0, 28000000.0 War of the Worlds, Stephen Spielberg, 118, 01/01/2005, 01/01/2007, 22000000.0, 14000000.0 Program Specifications: Write a program that will do the following: 1. It must be adequately commented. 2. It must have variables that are appropriately named. 3. It must have a function to adequately prompt the user to perform the following action by printing the following menu: a. Add a new movie b. Print the director, movie length, theater release date, DVD release date, production cost, and first-year revenue for a single title (search by title) c. Print the entire movie information listing d. Quit 4. It must have a function to read a small library collection file stored in myMovies.dat. 5. It must store the library collection data in an array called movielibrary. 6. It must print (to common input) the director, movie length, theater release date, DVD release date, production cost, and first-year revenue for a single title specified by the user. 7. It must make use of at least one other additional function not specified above to perform necessary steps within the program. You could do a search by another category or make use of helper functions to do the other tasks. Hints: 1. Each movie is stored as a struct movieType which includes the following information: - title: string - director: string - length: int - theaterReleaseDate: dateType - dvdReleaseDate: dateType - productionCost: double - firstYearRevenue: double 2. The struct called dateType given in the above struct bookType is represented as follows: - month: int - day: int - year: int 3. Review the information provided in the data file myMovies.dat to understand how the data is arranged so you can program the function for reading in the data correctly. 4. The movieLibrary is an array of movieType struct.
