There are two alternative Plans for operating a high-speed inter-city rail service. In Plan I, the service connects city A with city B through city C where the rail makes a stop to load or unload passengers. The rail transportation system is assumed to be perfectly symmetrical with respect to direction of travel. The link travel times are 2 hours between each pair of cities in both directions. The time it takes to service the train at each node is 0.5 hours. In the alternative Plan II, the train company considers to stop servicing the smaller city C, in order to provide a better level of service for the users in the city A and city B. According to Plan II, the travel time between the major cities A and B in both directions will be reduced to 3.5 hours. The time it takes to service the train in both city A and city B is still 0.5 hours. Q2 (D) Calculate the travel demand between all pairs of cities for both Plan I and Plan II as well as the corresponding company revenues for all city…

The City Council proposed to utilize a government-owned land with an area of 21,600 square meters. One-third of it will be used for a picnic area while the rest of the land will be planted by mango trees. As the city engineer, you were tasked to determine the following and illustrate its graph: 1. The dimensions of the picnic area with minimum cost of fencing given that area is to be rectangular and to be fenced off on three sides not adjacent to the highway. 2. The number of mango trees that leads to a maximum yield given that if 50 trees are planted, the average yield per tree will be 400 kilos while the average yield will decrease by 2 kilos per tree for each additional tree in the same area due to overcrowding.
The Organization for Economic Cooperation and Development (OECD) consists of 20 industrialized countries. For these nations, the prediction equation relating y = child poverty rate (in percentage points) to x = social expenditure as a percentage of gross domestic product (GDP) is = 22-1.3x. In 2000, the actual child poverty rate ranged from 2.8% (in Finland) to 21.9% (in the U.S.). Social expenditure as a percentage of GDP ranged from 2% (in the United States) to 16% (in Denmark). Using the linear prediction equation and plugging in the actual x-values (social expenditure rates) provided above, find the predicted child poverty rates for the United States and for Denmark. The x-values for both of these countries are provided above in the description of the study. (Note: You do not need to convert the percentages into proportions before or after plugging them into the equation.) The predicted child poverty rate for the U.S.: The predicted child poverty rate for Denmark:
