please answer them all and the selected option is not correct. thanks in advance !!

The table below provides coordinate data (with the origin the southwest corner (lower left hand corner) of the mapping - so your x coordinate is east of the corner and your 7 coordinate is north of the corner) for five European cities. Demand levels are also provided in the table below. A company is wishing to locate a distribution center so as to minimize distances between these cities and decides to use a Center of Gravity model. Calculate the Center of Gravity coordinates. Based on these results, we can conclude that the new distribution center will be south and east of Vienna the new distribution center will be south and west of Berlin the new distribution center will be north and east of Milan the new distribution center will be south and west of Paris Consider the table in the previous question. Suppose that demand at Milan changes to 5000 . the distribution center will need to be moved further north and further west the distribution center will need to be moved further south and further east the distribution center will need to be moved further north and further east the distribution center will need to be moved further south and further west Consider the table below, representing the cost of shipping one unit of a good from each source (New Jersey, Chicago, and Denver) to each destination (Atlanta, Houston, Los Angeles, and Seattle). Assume no fixed costs and that all three sources are available for operation. Demand and capacity are also as given in the table. FOLLOWING THE TRANSPORTATION LP we did in class, and using Excel Solver, determine how many units should be shipped from each source to each destination so as to minimize cost of transshipment. From these results we know: Los Angeles will receive all 40 units demanded from Denver all of the available options are correct Atlanta will receive all 30 units demanded from New Jersey Seattle will receive all 20 units demanded from Chicago
