- The success of a project depends on the effort level of a worker. In case of successthe revenues will be 400,000 TL whereas in case of no-success the revenues will be 0. The workercan provide a low effort level or a high effort level. The effort level cannot be observed by theprincipal. The worker requires an expected salary of 60,000 TL to provide the low effort leveland an expected salary of 80,000 TL to provide the high effort level. The success probabilitiesfor the project are 40% in case of low effort level and 80% in case of high effort level. Whatshould be the minimum bonus (that is awarded in addition to the base salary in case of success)and the base salary for the worker so that the worker has the incentives to provide the higheffort level?Obtain the general solution VARIATION OF PARAMETERSfind the general solution by the method of variation of parameters.Decide whether the method of undetermined coefficients could also have been used.
- Determine the best (according to sum-of-squares-measure) curve y = Aebx, through the dataabove.Transformed equationln(y) = ln(A) + bxorY = a + bx.A college bookstore must order books two months before each semester starts. They believe that the number of books that will ultimately be sold for any particular course is related to the number of students registered for the course when the books are ordered. They would like to develop a bestfitting line to predict how many books to order. From past records, the bookstore obtains the number of students registered, X, and the number of books actually sold for a course, Y , for 12 different semesters.A scatterplot of the data along with the best fitting line is presented below. a. The correlation between the two variables is r = .89. Calculate and interpret the value of r2.b. The equation for the best fitting line is Y = 9.30 + 0.673X. Explain and interpret the value of 9.30.c. How many books should the store order for a class of 50 students? Would you trust this prediction?Explain with proof Least Squares Regression Unbiased Estimators y^
- Find the characteristic equation, complementary solution, and particular solution using the method of variation of parameters.A blending process is to combine three components to create a final blind of 60,000 gallons. The three components cost $2, $1.5 and $1.25 per gallon respectively. Total cost of the components should equal 90,000. Another requirement of the blending is that the number of gallons used of component 1 should be twice the amount used of component three. Determine whether there is a combination of three components satisfying the blending restriction. Apply Gaussian elimination approach.Professor Cambridge collected data from each of his 1st year Chemistry student. If the population if Professor Cambridge’s Chemistry students (all students in the data set) is it possible to calculate the parameters? Or it is limited only to statistics? Why do you think so? If the population involves both the junior and senior students, and the dataset is the sample from that population, is it possible to calculate the parameters for that population? Or is it limited to statistics? Why do you think so?
- Determine the complete solution of Simulation equationFind the equation of the regression line using the method of least squareswrite your solution clearly. thanksCLUB18 is a manufacturer of golf paraphernalia. Management believes that CLUB18’s market share can be increase by the design of a different golf ball that is easier to shoot straight and far. Therefore they are examining a new covering that can help them to obtain these results. In particular, test of the distance of shot with a driver were done on the driving range with golf balls which have the current covering and the new covering with the following results: Model Model Model Current New Current New Current New 264 277 270 272 263 274 261 269 287 259 264 266 265 264 264 289 284 262 272 266 280 281 263…
