Problem 1:

four hospitals located in an urban area are collaborating to establish a centralized blood bank facility that will serve them all. the hospitals are located at the following coordinates: (5,10), (7,6), (4,2), (16,3). the number of deliveries to be made to each hospital each year is estimated as 450, 1200, 300 and 1500, respectively. due to the urban location, rectilinear travel can be assumed.

a) compute the optimal location for the blood bank if the total distance travelled each year is to be minimized, under the assumption that the delivery vehicle will deliver to only one hospital on each trip. (is this realistic? )

b) compute the location that minimizes the maximum rectilinear travel distance from the blood bank to any existing hospital.

Calculate riverside’s financial ratios for 2014. assume that riverside had $1,000,000 in lease payments and $1,400,000 in debt principal repayments in 2014. (hint: use the book discussion to identify the applicable ratios.)

Which of the following is true about presentation methods for providing training? audiovisual techniques are most effective when they are used alone. mobile technologies include training methods such as on-the-job training, simulations, business games and case studies, behavior modeling, interactive video, and web-based training that require the trainee to be actively involved in learning. the typical users for teleconferencing include employees who are part of a workforce that spends most of its time traveling, visiting customers or various company locations and has limited time available to spend in traditional training activities. webcasting involves classroom instructions that are provided online through live broadcasts. classroom instruction is no longer a popular training method because of new technologies such as interactive video and computer-assisted instruction.
