A company has $19,310 avallable per month for advertlsing. Newspaper ads cost $160 each and can't run more than 22 times per month. Radio ads cost $620 each and can't run more than 31 times per month at this price. Each newspaper ad reaches 6500 potential customers, and each radio ad reaches 7700 potential customers. The company wants to maximize the number of ad exposures to potential customers. Use n for number of Newspaper advertisements and r for number of Radio advertisements. Maximize P = subject to 22 < 31 < $19, 310 Enter the solution below. If needed, round ads to 1 decimal palace and group exposure to the
QUESTION 15 Let x- number of units of product A to produce and let x,-number of units of product B to produce. Consider the following objective function: Maximize zx + 2xz. Subject to the following constraints: x+ X25 12 (resource ), x, S8 (resource i), x2573 (resource l, and x220. What will the optimal objective function value be?
You choose how much time a day to devote to sleeping (s) and fun (f). Suppose you get utility, which you seek to maximise. However, you face two major restrictions: there are only 24 hours in a day, and you read somewhere that it is essential to get at least 3.50 hours of sleep every day. In the case where both inequality constraints hold with strict equality, what is the value of the multiplier attached to the second constraint? (Round to two decimal places.) Your Answer: Answer
What should be the corresponding objective function for the LP model in this problem? Maximize z = 2x + y Maximize z = x + 2y Minimize z = x + 2y Minimize z = 2x + y
Q4 / If we have the following table, which represents the primary basic solution of the corresponding (binary) model, noting that the objective function of the binary model? Non-Basic Variables B.V R.H.S S2 SI Y2 Y1 00 -80 -30 Z 018 2 sl 104 1 6. s2
Question 16 Suppose that you have downloaded data on the daily share prices for a company for the period from the start of 2020 to the end of 2020 from the website of Yahoo Finance UK. You have also calculated the daily rates of return for the company's shares as (closing price - opening price)/opening price. By using the knowledge that you have gained from descriptive statistics, how can you obtain useful information about the company's share performance in terms of risk and return using a range of alternative indicators? Note that you should give necessary formulas for the technical concepts wherever they may apply.
