A hurricane has been predicted to make landfall in Louisiana. The counties that lie within the path of the storm along with current population estimates are given in Table 1 below.  There are several regional warehouses located in Texas, Alabama and Georgia that have capacity available to lease so that supplies can be prepositioned in advance of the storm.   The lease capacity available at each of the warehouses is 100,000 units of MREs (meals ready-to-eat). The cost to lease each warehouse along with the capacity available is displayed in Table 2. The distance (in miles)  to ship product to each of the counties from each possible warehouse location  is summarized in Table 3. Assume travel cost is proportional to distance traveled.  Formulate a mathematical model that will determine which of the warehouses to use to preposition MREs and the amount shipped from each warehouse to each of the counties to assist those who are in need after the storm.  Assume that 25% of the population will…

Assume that the production of 1 unit of magnesium requires 0.4 units of magnesium and 0.4 units of aluminum, and that the production of 1 unit of aluminum requires 0.2 units of magnesium and 0.7 units of aluminum.Find the production schedule that satisfies an external demand for 30 units of magnesium and 90 units of aluminum.

For a particular process, originally each 200 units of product manufactured yielded 180 conforming units, 9 units that must be scrapped, and the remaining units that must be reprocessed.  Each scrapped unit results in a $30 loss and each reprocessed unit requires an extra 0.30 hours of processing time.  The resource time of producing the original 200 units is 30 hours.  As a result of a quality improvement program that was recently introduced, for each 200 units manufactured, the process now yields 190 conforming units, 1 unit to be scrapped, and the remaining units that must be reprocessed. Calculate the scrap cost for the new process.

Many electronic (e-)cigarettes work by vaporizing a liquid mixture of flavors and (usually) nicotine that is contained in a cartridge. When the smoker inhales on the e-cigarette , the liquid passes through a heating element and turns to a mist. Of importance to a manufacturer and consumer is the number of "puffs' that a cigarette can deliver before the cartridge needs to be replaced. À puff is defined as a two-second inhale. One manufacturer notes that the number of puffs that its cartridge can deliver, Y, is a normally distributed random variable with a mean of 260 puffs and a standard devlation of 15 puffs. The manufacturer will replace a customer's cartridge free of charge if the number of puffs the customer gets out of the cartridge is below some guaranteed number. Suppose the manufacturer wants to replace no more than 2% of its cartridges as part of the guarantee. How many puffs should the manufacturer guarantee that a cartridge can produce? Round DOWN to the nearest whole puff.…

Two sectors of some economy are Sector 1 and Sector 2. The input-output table involving these two sectors results in the following value for (I-4)-, where 1.21 0.155 (I-A)-! = 0.002 1.1242 How many additional dollars worth of production of Sector 2 must be produced to meet a $1 increase in the demand for products of Sector 1? a. $0.155 O b. $1.21 O c. $1.1242 O d. $0.002 O e. $0.9692

Teddy Equipment Rental (TER) rents farm equipment in an agricultural town in Texas. Five customers arrive between 8 AM and 9 AM. The table below shows data regarding their arrival and service times.  Assume the following: Teddy Equipment Rental’s queuing system does NOT follow M/M/1. 8:00 AM is the starting time and there is only one server who is continuously working (no breaks) until 9 AM. The server has to complete ‘servicing’ one customer before they can begin ‘servicing’ another customer. Customer Number Arrival Time Service Time Service Ends 1 8:06 AM 2 8:08 AM 2 8:07 AM 10 8:18 AM 3 8:12 AM 10 8:28 AM 4 8:24 AM 11 8:39 AM 5 8:30 AM 7 8:46 AM   In the above Teddy Equipment Rental mini-scenario, the average time a customer is in the system is: a. 5 minutes b. 8 minutes c. 12 minutes d. More than 13 minutes

Calcium is the most abundant mineral in the human body and has several important functions. Most body calcium is stored in the bones and teeth, where it functions to support theirstructure. Recommendations for calcium are provided in Dietary Reference Intakes, developed by theInstitute of Medicine of the National Academy of Sciences. The recommended adequate intake (RAI) of calcium for adults (ages 19–50 years) is 1000 milligrams (mg) per day. Suppose that we want to perform a hypothesis test to decide whether the average adult with an income below the poverty level gets less than the RAI of 1000 mg.a. Determine the null hypothesis for the hypothesis test.b. Determine the alternative hypothesis for the hypothesis test.c. Classify the hypothesis test as two tailed, left tailed, or right tailed.
