- Five workers are available to perform four jobs. The time it takes each worker to perform each job is given in the following table. The goal is to assign workers to jobs so as to minimize the total time required to perform the five jobs: Time Worker Job 1 Job 2 Job 3 Job 4 Job 5 1 10 15 10 15 16 2 12 8 20 16 14 3 12 9 12 18 22 4 6 12 15 18 8 5 16 12 8 12 8 Which worker should be assigned to which job? What is the total time required? (Hint: Use the Assignment model). If there are only 4 jobs (assume that job 5 is not required), how would the workers be assigned to jobs? (Hint: Change the constraints in the Assignment model).Data was collected for 40 randomly selected trees growing in the median strip of a busy freeway. The height of each tree (in inches) was recorded. Data was recorded to the nearest whole inch. The data is summarized in the histogram below. Based on this histogram, determing the minimum and maximum possible tree heights for the recorded data. Note: Each class contains its lower class boundary, but not its upper class boundary.Minimum tree height = inchesMaximum tree height = inchesThe exercise involving data in this and subsequent sections were designed to be solved using Excel.

Then, the answers from each of those computers are combined into one answer. Notice that the first sentence clarifies that processing (and storing) is done by "different computers." The second sentence mentions these different computers again, this time referring to them as "those computers". What term is often used to refer to each one of those different individual computers? (hint: The general term is often followed by a number as a means of identifying specific computers in the programming model.) Cluster Processor O Client O Node
