Three weeks after recovery from medically treated NEC, a preterm infant develops progressive abdominal distension, bilious emesis, and decreased stooling after initially tolerating feeds. Perfusion, platelet count, and lactate remain normal. Abdominal radiographs show dilated bowel loops without pneumatosis. Which complication should be suspected?

Returns on stocks S and bonds B are generated by the following model: RS = 0.02 + 1.4Rm + eS, RB = 0.01 + 0.8Rm + eB, where Var(Rm) = 0.182 = 0.0324, E[Rm] = 0.06, E[eS] = E[eB] =0, Var(eS) = 0.302 = 0.09, Var(eB) = 0.102 = 0.01. Finally, Cov(eS,Rm) = Cov(eB,Rm) = Cov(eS,eB) = 0. For negative answers, please add a – sign: Example: -0.005)    Expected return of RS:     E[RS] =

Consider a process consisting of three resources in a worker-paced line and a wage rate of $10 per hour. Assume the process is capacity-constrained. Resource Processing time (minutes) Number of Workers 1 10 2 2 6 1 3 16 3 Answer the follwowing four questions.

A company producs bottled drink on a machine-paced line with four steps: (1) the bottling machine takes 1 second to fill a bottle, (2) the lid machine takes 3 seconds to cover the bottle with a lid, (3) a labeling machine takes 5 seconds to apply a label to a bottle, and (4) the packaging machine takes 4 seconds to place a bottle into a box. Problem data are summarized below. Process Step Number of Machines Seconds per Bottle Bottling 1 1 Applying a lid 1 3 Labeling 2 5 Packaging 1 4 Question: If one more identical labeling machine is added to the process, how much is the increase in the process capacity going to be (in terms of bottles/hour)?

A box that stands for an activity in a process diagram may carry inventory in it.

Which process step has the highest capacity?

If the wage rate is $36 per hour per person, what is the direct labor cost per unit (in $)?
