Using the pandas packge in python, the program which performs the required calculation goes thus :

file_name = input()

#user types the filename

df = pd.read_csv(file_name, names=['hours_worked', 'rate']

#file is read into a pandas dataframe

df['salary'] = df['hours_worked'] * df['rate']

#salary column is created using the product of rate and hours worked

highest_salary = df['salary'].max()

#the max method returns the maximum value of a series

print('highest_salary)

lowest_salary = df['salary'].min()

#the min method returns the minimum value of a series

print('lowest_salary)

avg_salary = df['salary'].mean()

This is an example with solution:

Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 12, Job B = 2, Job C = 15, Job D = 7, and Job E = 3 ms.

a. Using FCFS, and assuming the difference in arrival time is negligible, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for all five jobs?

Answer: The order of processing for the given jobs = A->B->C->D->E.

Total time needed to process all the jobs = 12+2+15+7+3 = 39 ms.

Turn around time for job A = 12 ms.

Turn around time for job B = 15 ms.

Turn around time for job C = 30 ms.

Turn around time for job D = 37 ms.

Turn around time for job E = 40 ms.

Answer : Therefore, the average turnaround time = (12+15+30+37+40)/5 = 26.8 ms.

Order of processing is A, B, C, D, E and Total time to process and Average turnaround time is 39 ms and 24 ms

Order of processing = A, B, C, D, E

Total time to process all five jobs = Job A + Job B + Job C + Job D + Job E

Total time to process all five jobs = 2 + 12 + 15 + 7 + 3

Total time to process all five jobs = 39 ms

Average turnaround time = [(2-0) + (2+12-0) + (2+12+15-0) + (2+12+15+7-0) + (2+12+15+7+3-0)] / 5

Average turnaround time = (2+14+29+36+39) / 5

Average turnaround time = 24 ms

Therefore, in order to run the program in the shortest time, you should delay for 3 years

Given that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months.

Exponential equation as a function of time can be expressed as

P(t) = [tex]P_{0}[/tex][tex]R^{t/T}[/tex]

Quantity P will be increasing exponentially when R > 1. And it will decrease exponentially when R < 1.

Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish.

Let the time required to run and complete a program for time t years be P(t).

If the speed doubling every 18 months, which is 3/2 years. This will eventually cause the running time to decrease by half (0.5)

P(t) = 7[tex](1/2)^{3t/2}[/tex] = 7[tex](2)^{-3t/2}[/tex]

The total time T will be sum of the delay time t and the time of running the program. That is

T(t) = t + P(t)

T(t) = t + 7[tex](2)^{-3t/2}[/tex]   .......... (2)

We can calculate the minimum time t by differentiating the above equation and make it equal to zero.

dT/dt = 1 + 14/3[tex](2)^{-3t/2}[/tex](ln0.5) = 0

14/3[tex](2)^{-3t/2}[/tex](ln0.5) = -1

[tex](2)^{-3t/2}[/tex](ln0.5) = -3/14

[tex](2)^{-3t/2}[/tex] = -3/14ln0.5

Log (natural logarithm) both sides

-3t/2ln2 = ln(3/14ln2)

make t the subject of formula

t = - 3ln(3/14ln2) ÷ 2ln2

t = 2.5 approximately

To know how long you should delay buying the computer and starting the program so that it will finish in the shortest amount of time from now, substitute t into equation 2

T(2.5) = 2.5 + (7)[tex]2^{-3(2.5)/2}[/tex]

T(2.5) = 2.5 + 0.5202

T(2.5) = 3.02 years

T (2.5) = 3 years approximately

Therefore, in order to run the program in the shortest time, you should delay for 3 years

Answer:

While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.

If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.
