ctions are used to map elements from one set to another. For example, barcode and QR scanner systems are developed by programmers to use specific symbologies to map the pattern in the barcode to actual digits. The check digit or the final digit is used to determine whether the function is true (known good) or false (errors in the mapping occurred). RFID system developers also use functions to develop a pairing protocol that securely connects legitimate devices within a specific proximity.

Discuss the challenges and ethical considerations related to the collection and use of customer data in CRM systems.

A manager is simulating the number of times a machine operator stops a machine to make adjustments. After careful study the manager found that the number of stops ranged from one to five per cycle and that each number of stops was equally likely. Using the random numbers 0.17 and 0.47 (in that order), determine how many stops for adjustments each of the next two cycles will have. The first cycle will have stops and the second cycle will have stops.
