Problem What is the average CPI of this program? We have the computer from the previous problem with the following specs CPI for each instruction class CPI of A B C CPI 1 2 3 We have the program where the instructions distributed the following way CPI for each instruction class Portion of A B C 50% 35% 15% Lets assume X instructions in the program otes #_cycles = (X instr *0.5) * 1 cycle/instr + (X instr * 0.35)*2 cycle/instr + (X instr * 0.15)*3 cycle/instr = x*0.5 cycle + X*0.7 cycle + X*0.45 cycle = X*1.65 cycle Aver CPIX*1.65 cycles / X instr = 1.65 cycle/instr I

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…

The computed approximation should be accurate to less equal to 10 decimal places (i.e., the absolute value of nin+1) the sum result of current kth iteration subtract from the sum result of the previous (k-1)th iteration is less equal to 0.01). The program should display the approximation of the series and the error bound. An alternating series that converges has an error bound equal to the magnitude of the next term in the series, for example if was approximated (-1)-1 nin+1) using N = 3, (-1)-*, the error bound is (-1)" with n = 4, nin+1) .
