9) An air conditioning and heating repair firm conducted a study to determine if the
average outside temperature could be used to predict the cost of an electric bill for a
home during the winter months in Richmond, VA. It was determined that a quadratic
model could be used and the following prediction equation was established:
Y = $1557.76 – 55.05X1 + 0.56X2
where Y = monthly cost, X1 = average temperature, and X2 = average temperature2

monthly electric bill?
(b) If January has an average temperature of 40 degrees, what is the forecasted monthly
electric bill?

D) Frederick W. Taylor
E) Charles Babbage

A) primary
B) transient
C) NOC
D) balanced
E) steady
12) If the fixed costs are $10,000 and the variable cost/unit is $10 and the break-even is
100 units, what is the selling price per unit?
A) $200.
B) $110.
C) $59.
D) None of the above
E) Unable to say without more information
13) A suburban specialty restaurant has developed a single drive-thru window.
Customers order, pay, and pick up their food at the same window. Arrivals follow a
Poisson distribution while service times follow an exponential distribution. If the
average number of arrivals is 6 per hour and the service rate is 2 every 15 minutes, what
proportion of the time is the server busy?
A) 0.25
B) 0.50
C) 0.75
D) 2.25
E) 3.00

17) Table 14-4
Cuthbert Wylinghauser is a scheduler of transportation for the state of Delirium. This
state contains three cities: Chaos (C1), Frenzy (C2), and Tremor (C3). A transition
matrix, indicating the probability that a resident in one city will travel to another, is
given below. Cuthbert’s job is to schedule the required number of seats, one to each
person making the trip (transition), on a daily basis.
Using the data given in Table 14-4, how many people can we expect to find in each city
tomorrow evening?
A) Chaos = 90, Frenzy = 110, Tremor = 100
B) Chaos = 110, Frenzy = 100, Tremor = 90
C) Chaos = 80, Frenzy = 90, Tremor = 130
D) Chaos = 100, Frenzy = 130, Tremor = 70
E) None of the above
