In class, we solved the firm's cost-minimization problem when its production functiorn is given by f(x1, T2) ??? X2-a, where ? E (0, 1). Now suppose that with ?, ? 0. f you were to solve the cost-minimization problem (given some a 1, ?2, and y) and derive the results in the lecture slides again, what would change and what would not change? Explain. (You don't have to solve the problem again although you can if you choose to.) b)...

Problem: Allow the user to enter a positive integer value to represent the seed value for the random number generator. Next, generate a random integer that represents a possible number of points that a student may earn in a given class (0 to a maximum of 1000 possible points). Calculate the corresponding letter...

This question is a variant of the Sport Hotel example that was
presented in class, in the class notes, and in the Real Option
chapter.
The change to consider is this: suppose that the value of the hotel
is one of two values: $9.4 million if the city is
successful in obtaining the franchise (and not $8 million as in the
original problem) or $3.7 if the city is not
successful in obtaining the franchise (and not $2 million as...

Classification in Python: Classification In this assignment, you will practice using the kNN (k-Nearest Neighbors) algorithm to solve a classification problem. The kNN is a simple and robust classifier, which is used in different applications. The goal is to train kNN algorithm to distinguish the species from one another.

Please answer the following question. Please show all your work/explanation. This problem provides a mathematical example of the previous problem and asks you to solve the household’s problem using the method of Lagrange Multipliers. Suppose the household’s preferences over Non-Durables and Health Services are given by U(N, H) = a log(N) + (1 − a) log(H) where 0 < a < 1, N is non-durable consumption and H is health services. Write the maximization problem of the household assuming prices...

ACCT 2102: In Class Problem - Hagan's Mountain Tutors Hagan's Mountain Tutors (HMT) specializes in tutoring college students in accounting. Tutors at HMT expect to work 2,000 hours a year for which they incur direct labor costs of $24,000. Indirect costs, which are expected to total $6,000, are assigned to clients based on tutors' direct labor hours. Student Miranda Mishugana, in a big panic over her ACCT 2102 exam, hired one of HMT's tutors to work with her for 10...
