Expand the function f(z) = (z − 1) / z^ 2 (z + 1)(z − 3) as a Laurent series about the origin z = 0 in all annular regions whose boundaries are the circles containing the singularities of this function.

Given the code segment:

def f1(a, b = 2):

if a :

print(1)

f1(1)

what is the result of executing the code segment?

a) Syntax error

b) Runtime error

c) No error

d) Logic error

in which scenario(s) is using a dictionary useful?

a) To store the dates of lesson that each student is absent for so that warning letters may be issued to student exceeding a limit.

b) To store the student numbers for students who sat for an exam

c) To retrieve email of students who are absent for an exam. The student numbers will be entered into the recipient field and the system should display the student email.

d) The marks should be entered into the exam system. The exam system displays rows of student number, and the marks can be entered against the student number. The grade will be computed and reflected in the student row .

which expression returns True when a number, x is not and odd number between 1 (inclusive) and 100 (inclusive), and returns False otherwise?

a) x not in range(100) and x % 2 !=0

b) x not in range(1,101) and x % 2 !=0

c) not( x in range(1,101) and x % 2 1=0

d) x not in range(1,101) or x % 2 !=0

A box contains 1 fair coin and 1 2-Headed coin. A coin is drawn and flipped several times.

(a) The first flip results in Heads. What is the probability that the coin is fair?

(b) 3 flips result in all Heads. What is the probability that the coin is fair?

(c) 5 flips result in all Heads. What is the probability that the coin is fair?

(d) How many flips of all Heads are required to know with 99.9% accuracy that the coin is not fair?

1. Copy the files from Assignment 1 to Assignment 3.

2. Modify the PetFoodCompany header to mention a friend function called "computeBonusBudget". This method should compute the bonus budget as netIncome() * BonusBudgetRate and this method should exist in the driver program - not the Class defintion.

3. Modify the output of the program to display the results of the computeBonusBudget.

Enter Total Sales: 1000

Enter Total Expenses: 600
Net Income = 400
Bonus Budget = 8
