- A merchant who sells newspapers and magazines at the corner kiosk heard you manage the Times’ inventory and asks for your advice. She has a small, variable number of customers who daily purchase the Chicago Sun Times. In order to get the newspapers in time, she has to place an order for the next day’s newspapers before noon. She pays $0.50 for each newspaper and sells them for $1.50 each. She has kept detailed records of her past sales of the Chicago Sun Times and estimates that 10% of the time she sells 10 newspapers, 40% of the time she sells 11, 30% of the time she sells 12, and 20% of the time she sells 13. (a) What is the merchant’s marginal profit and marginal loss? (b) Determine how many Chicago Sun Times newspapers she should buy every day to maximize expected profits. (c) Calculate the merchant’s expected profits for the optimal order quantity. (d) The merchant has always purchased 13 newspapers, thinking that the best way to maximize profits was to always meet the demand.…How should be the following given be treated while estimating national income (1) bonus paid to employeesHow does the particle used in FastSLAM differ from the one used in Monte Carlo localization?
- T or F A household is frequently used in analyses because more consistent data are usually collected at that level.Select the scenario which is an example of voluntary sampling. Answer Keypad Keyboard Shortcuts Tables An airline is interested in getting feedback about their on-board catering experience. They place a questionnaire in the pocket behind each airline seat for passengers to O fill out. An urban planner is interested in determining the traffic volume along a particular road. To estimate the traffic volume, he counts the number of cars that go by during the next 30 minutes. O To determine the mean domestic electricity consumption in the region, the electric company collects data from randomly selected households in the given region. A fitness center has 400 male clients and 300 female clients. They plan to buy new equipment, so they randomly select 80 male clients and 60 female clients and ask them what equipment they use the most.10.61 The per-store daily customer count (i.e., the mean number of customers in a store in one day) for a nationwide convenience store chain that operates nearly 10,000 stores has been steady, at 900, for some time. To increase the customer count, the chain is considering cutting prices for coffee beverages. The question to be determined is how much to cut prices to increase the daily customer count without reducing the gross margin on coffee sales too much. You decide to carry out an experiment in a sample of 24 stores where customer counts have been running almost exactly at the national average of 900. In 6 of the stores, the price of a small coffee will now be $0.59, in 6 stores the price of a small coffee will now be $0.69, in 6 stores, the price of a small coffee will now be $0.79, and in 6 stores, the price of a small coffee will now be $0.89. After four weeks of selling the coffee at the new price, the daily customer count in the stores was recorded and stored in . At the 0.05…

- how 9652648263t = 119.245 ?In October 2015, amid rising fears about the security of credit card transactions, financial institutions and businesses made the transition to using chip cards. Unlike the quick swipe of a magnetic stripe on the back of traditional credit and debit cards, chip cards have to be left inside the terminal while the embedded chip verifies the transaction. While there is no consistent method for measuring transaction speed, news agencies report average chip speeds of anywhere from 8 seconds to 13 seconds. The switch to chip readers was precarious, with many businesses taping over the chip card slots in the terminals until the kinks were worked out. Even after a year, some businesses still could not process chips and continued to utilize the magnetic stripe for transactions. Financial institutions thought the additional security benefits of the chips would overshadow the added wait times. Yet a survey conducted by Harbortouch, a leading point-of-sale company, in 2016 showed that nearly four…One example of a specific environmental indicator which can be used to measure the level of development within a country is, the tons of toxic that are released annually.
