Donna shader, manager of the winter park hotel, is considering how to restructure the front desk to reach an optimum level of staff efficiency and guest service. at present, the hotel has five clerks on duty, each with a separate waiting line, during the peak check-in time of 3: 00 p. m. to 5: 00 p. m. observation of arrivals during this time show that an average of 90 guests arrive each hour (although there is no upward limit on the number that could enter at any given time). it takes an average of 3 minutes for the front desk clerk to register each guest. ms. shader is considering three plans for improving quest service by reducing the length of time quest spend waiting in line. the first proposal would designate one employee as a quick-service clerk for guests registering under corporate accounts, a market segment that fills about 30% of all occupied rooms. because corporate guests are preregistered, their registration takes just 2 minutes. with these guests separated from the rest of the clientele, the average time for registering a typical guest would climb to 3.4 minutes. under plan 1 noncorporate guests would choose any of the remaining four lines the second plan is to implement a single-line system. all guests could from a single waiting line to be served by whichever of five clerks became available. this option would require sufficient lobby space for what could be a substantial queue the use of an automatic teller machine (atm) for clerks is the basis of the third proposal. this atm would provide approximately the same service rate as would a clerk. given that initial use of this technology might be minimal, shader estimated that 20% of customers, primarily frequent guest, would be willing to use the machines. (this might be a conservative estimate if the guests perceive direct benefits from using the atm, as bank customers do. citibank reports that some 80% of its manhattan customer uses its atms.) ms shader would set up a single queue for customers who prefer human check-in clerks, and the four clerks would serve in addition to atm

step-by-step explanation:

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:
