4. Suppose that it takes an engineer T hours to repair a router, where T ∼ Exp(1/2). (a) Find the probability that it takes the engineer more than 2 hours to repair the router. (b) On May 1st, your router was broken at 5 pm and the engineer starts repairing at 6 pm. While he is repairing the router, you are working on your ECI 114 homework 3. However, the router has not been fixed when you finish the homework, which is at 10 pm. You do know that the homework is due 11:59 pm on Canvas. What is the probability that you do miss the submission? So, do submit the your works early!

Suppose that making a lamp takes 10 hours in Alphaland and 5 hours in Betaland. And also suppose that making a footstool takes 20 hours in Alphaland and 5 hours in Betaland. Assume as well that labour is the only productive resource needed in these industries, and is fully employed in both nations. Now Alphaland produces 1 more lamp (and decreases its production of footstools), and Betaland produces 1 less lamp (and increases its production of footstools). Using the above...

4. Suppose that you are the engineer in the charge of the gasification section of the Acme Substitute Natural Gas Company. ASNG Co. runs fixed-bed, dry-ash gasifiers. The raw gas is cleaned, shifted, and sent to a methane synthesis unit. Every morning you receive a report from ASNG’s analytical laboratory on the characteristics of the coal that will be fed to the gasifiers during the next day’s operations. One important characteristic is the ash fusion temperature (AFT), i.e., the temperature...

Suppose that C is the concentration of a drug in the bloodstream t hours after the initial dose is administered. Suppose the initial dose Co was 191.8 µg / mL and suppose that 189 µg / mL is administered every hour. If the body metabolizes and eliminates 35% of the concentration of drug C; in a period of one hour; determine C2, the concentration of the drug in the bloodstream two hours after the initial dose is administered.

Suppose that it takes an average Australian miner 10 hours to mine a ton of coal and 20 hours to mine a ton of manganese. It takes the average South African miner 4 hours to mine a ton of coal and 12 hours to mine a ton of manganese. a) For each miner, calculate the opportunity cost of mining a ton of coal and a ton of manganese. b) In what task does each miner have a comparative advantage? Briefly...

(8) Suppose T : R 4 → R 4 with T(x) = Ax is a linear transformation such that • (0, 0, 1, 0) and (0, 0, 0, 1) lie in the kernel of T, and • all vectors of the form (x1, x2, 0, 0) are reflected about the line 2x1 − x2 = 0. (a) Compute all the eigenvalues of A and a basis of each eigenspace. (b) Is A invertible? Explain. (c) Is A diagonalizable? If yes,...

Suppose ?(?) represents the number of bacteria in a dish t hours after the start of a lab experiment. a) Interpret the meaning of ?(20) = 100 100 is the average rate of change in the number of bacteria after 20 hours. 100 is the rate of change in the number of bacteria after 20 hours. After 20 hours, there are 100 bacteria in the dish. 100 is the total change in the number of bacteria between the first hour...

Suppose Ct is the concentration of a drug in the bloodstream t hours after the initial...

Suppose Ct is the concentration of a drug in the bloodstream t hours after the initial dose is administered. Suppose the initial dose C2was 217.6 ug/mL and suppose that every hour is administered 174 g/mL. If the body metabolizes and eliminates 54% of the concentration of the drug Ct over a period of one hour; determine C2, the concentration of the drug in the bloodstream two hours after the initial dose is administered. Response at two decimal valors.

Pat and Kris are roommates. Pat takes 4 hours to brew a gallon of root beer and 2 hours to make a pizza. Kris takes 6 hours to brew a gallon of root beer and 4 hours to make a pizza. These are their most preferred activities. (a) What is Pat’s opportunity cost to produce one pizza Note that an opportunity cost should be ex- pressed in goods, not resources, given up. (b) What is Kris’s opportunity cost to produce...

Graphs have to be made as well* 1.) Suppose it takes Zeeland 5 labor hours to make each car and 15 labor hours to make each robot, while it requires Antigo 1 labor hours to make each car and 10 labor hours to make each robot. Further suppose each nation has 90 labor hours available. 2.) What is the opportunity cost of one car for Antigo and for Zeeland? What about for one robot? 3.) Suppose each nation specializes according...

4) If the US has 250,000 hours available to produce 2 goods: Wheat which takes 2 hours per ton of wheat to produce and Airplanes which takes 1,000 hours per airplane to produce. If China has 500,000 hours available to produce 2 goods: Wheat which take 5 hours per ton of wheat to produce and airplanes which takes 3,000 hours per airplane to produce. a. Draw the PPF diagram for the US assume they consume half of each product without...
