We are given that the incubation time is normally distributed with a mean of 35 days and standard deviation of 2 days. Therefore, ? = and ? = .We wish to determine how many of the 10,000 eggs can be expected to hatch in 31 to 39 days. Since
35 − 31 = 4,
31 days is located standard deviations to the left of the mean. Similarly, 39 days is located standard deviations to the right of the mean.

Let S represent the amount of steel produced (in tons). Steel production is related to the amount of labor used (L) and the amount of capital used (C) by the following function:
S = 35L0.40 0.60
In this formula L represents the units of labor Input and C the units of capital input. Each unit of labor costs $150, and each unit of capital costs $200.
a. Formulate an optimization problem that will determine how much labor and capital are needed in order to produce 60,000 tons of steel at minimum cost. If the constant is "1" it must be entered in the box; if your answer is zero, enter "0".

You are told beforehand the capacity C of you gas tank in liters, your rate F of fuel consumption in liters/kilometer, the rate r in liters/minute at which you can fill your tank at a gas station, and the locations A = x1, ··· , B = xn of the gas stations along the highway. So if you stop to fill your tank from 2 liters to 8 liters, you would have to stop for 6/r minutes. Consider the following two algorithms: (a) Stop at every gas station, and fill the tank with just enough gas to make it to the next gas station. (b) Stop if and only if you don’t have enough gas to make it to the next gas station, and if you stop,fill the tank up all the way. For each algorithm either prove or disprove that this algorithm correctly solves the problem. Your proof of correctness must use an exchange argument.arrow_forward
