In this problem, you will solve for the equilibrium population of an idealized city experiencing rural-urban migration, following the augmented Harris- Todaro model from Chapter 3. The incomes earned in urban employment and in the rural area are y and yA, respectively, and t is commuting cost per mile. J is the number of available urban jobs. a) Suppose the city is a rectangle 10 blocks wide with the employment center at one end (it’s an island like Manhattan). The...

For each case study, you must develop an appropriate exercise prescription.  Use the FITT recommendations from the ACSM guidelines. You will need to calculate a workload for the particular type of mode of cardiovascular exercise you choose utilizing the metabolic equations. Once you pick an appropriate intensity, use the VO2R equation to calculate the oxygen consumption. Then use that to solve for the workload on the treadmill or cycle, whichever you think is best. Don't forget to indicate frequency and duration...

Please answer with method or formula used. A) Puenaa is getting married tomorrow, at an outdoor ceremony in the desert. In recent years, it has rained only 5 days each year. Unfortunately, the weatherman has predicted rain for tomorrow. When it actually rains, the weatherman correctly forecasts rain 90% of the time. When it doesn't rain, he incorrectly forecasts rain 10% of the time. What is the probability that it will rain on the day of Puenaa's wedding? B) A...
