An airline estimates with probability of 0.05 a passenger who bought a ticket won’t show up for the flight. The plane can carry 100 passengers, and the airline sells 102 tickets.
What is the probability that exactly 101 passengers show up to take the flight?
Draw the class diagram for the current implementation of the Personnel system (use
correct UML notations) .
b) Identify object oriented concept violations, content coupling, common coupling,
control coupling and stamp coupling situations in the code. (write the code segment
that show above coupling situation) .
c) Explain how you would fix object oriented concept violations, common coupling,
control coupling, and content coupling? Then, refactor the code to remove above
object oriented concept violations , common coupling, control coupling, and content
coupling. Objective of the refactoring is to remove above coupling situations but not
to remove any intended functionality of the system

5. Consider the market for bicycles as discussed in problems(1) and (3). If the price was $120, would a situation of excessdemand or excess supply exist? Identify this price level and thequantities demanded and supplied on a graph like the one you drewfor problem (3). Describe the economic forces that will tend tomove the price of $120 toward the equilibrium price. . . .
Write a brief, qualitative (no numbers!) report contrasting the three dynamic scenarios, describe the
key principles about bio-economic resource management that you have learned from manipulation
of this model, and explain their importance.

Question 1 [10 marks]: Identify each of the variables in the above table either as nominal, ordinal,
discrete or continuous.
Hint: Present your answer in a table by listing the variables in the first column, classification of the
variables in the second and value label in the third column.
Question 2 [20 marks]: Fill up the following table using appropriate summary statistics for each of the
listed variables. Discuss whether dyslipidaemia is related to HbA1c, diastolic BP, insulin status and
patients’ age.
Hint: outcome variable is dyslipidaemia.

Use the following information to answer the following question(s), using the SUMPRODUCT function.
Stone Age Surfboards is a small manufacturer of two types of popular high-tide surfboards, the Rockwell and the Limestone models. The manufacturing process consists of two departments: fabrication and finishing. The fabrication department has 15 skilled workers, each of whom works 5 hours per day. The finishing department has 5 workers, who also work a 5-hour shift. Each pair of Rockwell surfboards requires 3 labor hours in the fabrication department and 1.5 labor hours in finishing. The Limestone model requires 4.5 labor-hours in fabrication and 2 labor-hours in finishing. The company operates 6 days a week. It makes a per-unit profit of $60 on the Rockwell model and $75 on the Limestone model. Approximately 4.1 Rockwell models and 8.4 Limestone models are produced per day.
What is the total number of hours used for the finishing operation?

A permanent magnet DC motor is coupled to a load through a gearbox. If the polar moments of inertia of the rotor and load are J
r and J
b, the gearbox has a N:M reduction (where N > M ) from the motor to the load, the motor has a starting torque T
s and a no-load speed max , and the load torque is proportional to its speed ( T
t = kω),
a. What is the maximum acceleration that the motor can produce in the load?
b. What is the steady state speed of the motor and the load?
c. How long will it take for the system to reach 95% of its steady state speed?
1.) A 0.06 Kg rubber ball bounces off the floor. When it is 0.2m high its speed is 1.2 m/s.
a.)How much kinetic energy did it have immediately after losing contact with the floor?
b.) The apex (highest point) of the ball's motion after impact is 0.24m (note: It is still in motion at his point. This is a two dimensional motion.) How much kinetic energy does it have at the apex?
