A.EACH $ 5  BILLION INCREASE IN MONEY SUPPLY REDUCES THE RATE OF INTEREST BY 0.3 PERCENTAGE POINT

B.EACH 1 PERCENTAGE DECLINE IN INTEREST RATES STIMULATE 24 BILLION WORTH OF NEW INVESTMMENT.

C.MPC = 0.75 .

D.THE AGGREGATE SUPPLY CURVE IS SO FLAT PRICES DO NOT RISE NOTICABLY (NO INFLATION) WHEN DEMAND INCREASES. MAKE SURE DO ALL CALCULATION AS WELL PROPPER GRAPHS

Occupancy data from a single loop detector was obtained from a one way street. The loop detector has a length of 6 feet and was observed to have six vehicles cross over it in a period of 30 seconds. The duration and the length of each vehicle are shown in the table below. Use the average vehicle length in your calculations. Estimate the values of q, k and u (flow, density and speed)

1. A cylindrical shell is 3 m long; 1 m in diameter and the thickness of metal is 10 mm. It is subjected to an internal pressure of 150 N/cm². Calculate the change in dimensions of the shell and the maximum intensity of shear stress induced. Given E= 200 GPa and Poisson’s ratio =0.3.

b. Two shafts of the same material and same lengths are subjected to the same torque. If the first shaft is of a solid circular section, the second shaft is of hollow circular section, whose internal diameter is 2/3 of the outside diameter and the maximum shear stress developed in each shaft is the same, compare the weights of the shafts

The following data shows the quarterly profit (in thousands of dollars) made by a particular company in the past 3 years.

a. Use α = 0.3 to compute the exponential smoothing values for the time series. Compute MSE and the forecast of profit (in $1000s) for the next quarter.

1. Today is your 25^th birthday. Your goal is to retire when you turn 70 years old and have sufficient monthly income until your expected demise on your 99^th birthday. In order to realize your goal, you are planning to make deposits into a target-date retirement fund that is expected to generate 7.8% annual return, compounded monthly. You want to be able to make monthly withdrawals from this fund starting one month after your retirement until your expected demise. These monthly withdrawals will increase by 0.3% a month in order to compensate for the expected increase in price levels. Retirees are able to survive on $2,000 monthly income today. Your first withdrawal one month after your 70^th birthday, therefore, will be $2,000 adjusted for 0.3% expected monthly inflation.

1. You are planning to make equal annual deposits starting one year from today until you retire. Calculate your deposits.
2. You are planning to make annual deposits starting one year from today until you retire. However, you believe that you can increase your deposits 4% a year in line with the expected increase in your income. Calculate your first deposit.
3. You are expecting inheritance money in the amount of $200,000 when you turn 50 years old and planning to deposit this amount immediately into the fund. Based on this expectation, recalculate your answer to part b.

A semiprofessional baseball team near your town plays two home games each month at the local baseball park. The team splits the concessions 50/50 with the city but keeps all the revenue from ticket sales. The city charges the team $100  each month for the three-month season. The team pays the players and manager a total of $1000 each month. The team charges $10 for each ticket, and the average customer spends $6 at the concession stand. Attendance averages 30 people at each home game.

The team earns an average of (1)$___ in total revenue (tickets plus share of concessions) for each game and (2) $___ of revenue each season.

With total costs of (3)$____ each season, the team finishes the season with (4)$____ of profit.
