The Deepwater Horizon oil spill in the Gulf of Mexico on April 20, 2010 was "an environmental disaster of unprecedented proportions" and was a "devastating blow to the resource-dependent economy of the region" [1]. According to the Washington Post, it is estimated that 9857 9857 cubic meters of oil per day spilled into the Gulf of Mexico on August 2, 2010 Assume that an average of 9857 m^3/day of oil spilled into the Gulf of Mexico everyday and that it formed a hemispherical dome of radius r on the ocean floor. D) find the rate of change of the radius with respect to time when the volume of the oil spill is 50,000m^3. E) Since only the oil that is in contact with seawater can mix with seawater, it is important to know how much of the surface area of the oil spill is in contact with seawater. Find the rate of change of the hemisphere's surface area with respect to time when the volume of the oil spill is 50,000 m3. Include units in your answer. You should assume that only the top…

[Econometrics] The World Bank hires you to analyze the effect of the introduction of new irrigation systems in a series of Sub-Saharan African countries. They are particularly interested on their effect in the crop production of each country. They give you data for each country on the kilometers of irrigation tubes constructed, the total crop harvest, as well as information on the average educational attainment for each year between 2000 and 2017. Which type of analysis would you perform based on this information?
Veneer is the material of plywood that has higher resistance (psi) depending on wax coat (W1, W2, W3) and temperature (T1, T2, T3). In an experiment, a large thin wood panel sheet will be coated with a wax coat. This will then be divided into three portions where each will be subjected to a drying temperature. After processing, several sheets will then be pasted together, and the resistance will be measured. Two manufacturing companies will participate in the experiment with two runs for each company.

A factory produces furniture as the main product. One of the major components of the furniture product is a steel bar with the specification of the length at 1,250 mm with +/- 10% tolerance. Based on historical records, the average demand for steel bars is 1,000 units per month. The factory receives two quotation prices from two independent suppliers along with the quality control records from their production process of the steel bars as below: (refer to table image) Anticipating that a portion of the steel bars delivered will fall outside the specification limits, the factory is prepared to cut steel bars that are too long, while those that are too short will have to be discarded. Based on the above information, answer the following questions: a. Provide your assessment on the capabilities (based on their capabilities index) of the two suppliers as well as their estimated percentage of defective products against the factory’s specification of the steel bars. b. Which of the two…

A specimen of connective tissue (collagen) can be obtained from a beef steak. The temperature at which the collagen shrinks can be determined. A tender piece of meat tends to have a low collagen shrinkage temperature. So, the lower shrinkage temperature, the more tender the meat.It is believed that electrical stimulation of a beef carcass could improve the tenderness of the meat. In one study of this effect, beef carcasses were split in half; one side (half) was subjected to a brief electrical current and the other side was an untreated control. For each side, a steak was cut and tested in various ways for tenderness. In one test, the experimenter obtained a specimen of the connective collagen tissue from the steak and determined the temperature at which the tissue would shrink. The experimenter wishes to prove that electrical stimulation tends to improve the tenderness of the meat. The raw data are found in the table below. Let ? = 0.01. Table 1: Collagen Shrinkage Temperature…
