Write a program Ticket.py that will allow the user to enter actual speed
limit, the speed limit at which the offender was travelling, and the number
of previous tickets that person has received. The application should
calculate and display how many miles over the speed limit the offender
was travelling, the cost of the speeding ticket, and court cost. Use $10.00
as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.

Computer Won't Start. A computer that suddenly shuts off or has difficulty starting up could have a failing power supply. Abnormally Functioning Operating System or Software. Slow Internet.As a basic user of SAP Business One, which feature of the application do you like most?
Answer:
I like the software most because it is completely for the sales department. I am very satisfied with what this software provides since I work as a sales specialist.
Explanation:
As an internal auditor, I first have to check and make sure the business is going through all reports and operations and that SAP Business One has helped me a lot with reporting features. I'm a huge fan of SAP Business One. And how this software is incredibly fully integrated when an accountancy provider creates a new customer name or adds a new item in every module, and the non-duplicate data feature secures the master data from any duplicate item.
Intuitive sales quotation and sales order functions help salespeople to develop deals that they can conclude. The mobile app adds to the software's usefulness fantastically.
In general, the system has a good monetary value. I would recommend it to everyone involved in the decision-making process and it is my favorite.
For this activity, you will practice being both proactive and reactive to bugs. Both are necessary to get rid of errors in code.
Proactive:
Log in to REPL.it and open your Calculator program that you built in Unit 5.
In the index.js file, type and finish the following block of code that validates the input to make sure both are numbers (not letters or symbols):
try{
if (isNaN(…) || isNaN(…)){
throw …
}
else{
document.getElementById("answer").innerHTML = num1 + num2;
}
}
catch(e){
document.getElementById("answer")…
}
(Note: The || symbol is used in JavaScript to mean or . You can find this key to the left of the Z key if you’re using a PC or directly above the Enter key if you’re using a Mac.)
Add the finished code above to the correct place in your add() function. Make sure to delete this line since we moved it into the try block:
document.getElementById("answer").innerHTML = num1 + num2;
Paste the same code into the subtract() , multiply() , and divide() functions, making the necessary changes. Be careful with your divide() function since you already have an extra if else statement checking for a division by 0 mistake. (Hint: Cut and paste the entire if else statement inside the else block of your try statement.)
Test your program by typing in letters or symbols instead of numbers. Make sure you get the appropriate error message. (Note: The function is not supposed to check whether the text field is empty, only whether it contains non-numbers.)
When you are finished, share the link to your webpage with your teacher by clicking on the share button and copying the link.
Reactive:
The following Python program should print the sum of all the even numbers from 0 to 10 (inclusive), but it has two bugs:
x = 0
sum = 0
while x < 10:
sum = sum + x
x = x + 1
print(sum)
Complete a trace table and then write a sentence or two explaining what the errors are and how to fix them. You can choose whether to do the trace table by hand or on the computer. Turn in your trace table and explanation to your teacher.

For each compound below, identify any polar covalent bonds and indicate the direction of the dipole moment using the symbols δ +and δ-.
(a) HBr
(b) HCI
(c) H2O
(d) CH40
Answer:
H-Br bond is polar, hydrogen is partly positive and bromine is partly negative
H-Cl bond is polar, hydrogen is partly positive and bromine is partly negative
O-H bond in water is polar, hydrogen is partly positive and oxygen is partly negative
C-O bond in CH40 is polar, carbon is partly positive and oxygen is partly negative
Explanation:
A molecule possess a dipole moment when there is a large difference in electro negativity between two bonding atoms in the molecule.
The presence of dipole moments introduces polarity to the molecule. In all the molecules listed in the answer, the shared electron pair of the bond is closer to the more electronegative atom causing it to be partially negative while the less electronegative atom in the bond is partially positive.

Write a C++ program to accept a 5 digit integer and to validate the input based on the following rules.
Rules
1) The input number is divisible by 2. 2) The sum of the first two digits is less than last two digits. if the input number satisfies all the rules, the system prints valid and invalid, otherwise,
Example 1:
Enter a value: 11222
Output: Input number is valid
Example 2:
Enter a value: 1234
Output: Input number is invalid
Answer:
#include <iostream>
#include <string>
#include <regex>
using namespace std;
int main()
{
cout << "Enter a 5-digit number: ";
string number;
cin >> number;
bool valid = regex_search(number, regex("^\\d{4}[02468]$"));
if (valid) {
valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))
< stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));
}
cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string

A) Why should assembly language be avoided for general application development?
B) Under what circumstances would you argue in favor of using assembly language for developing an assembly language program?
C) What are the advantages of using a compiled language over an interpreted one?
D) Under what circumstances would you choose to use an interpreted language?
Answer:
(A) Assembly language should be avoided for general application development for the following reasons:
i. It is difficult to write assembly language codes. It does not contain many tools and in-built functions to help with the development of these applications.
ii. Since general application development requires that the application be machine independent, writing such applications in assembly language (which is a low level, machine dependent language) might be a pain as it would require that the writer have sufficient knowledge of hardware and operating systems.
(B) The following are the circumstances where assembly language should be used:
i. Assembly languages are low level languages that are very close to machine languages that the machine or processor understands. Therefore, when writing codes for programs that should directly communicate with the processor, assembly language should be used.
ii. Since assembly language codes are machine dependent, when there is a need to write applications for target machines, they should be used.
iii. If there is a need to have very great control of certain features of your application and resources to be consumed such as amount of RAM, clock speed e.t.c, assembly languages are a great tool.
(C) Some of the advantages of compiled language over an interpreted language are:
i. Compiled languages are way faster than interpreted languages because the compiled languages are converted directly into native machine codes that are easy for the processor to execute. Put in a better way, with compiled languages, codes are compiled altogether before execution and therefore reduces the overhead caused at run time. Interpreted languages on the other hand executes codes line after line thereby increasing the overhead at run time.
ii. Since codes are compiled first before execution in compiled languages, nice and powerful optimizations can be applied during the compilation stage.
(D) Interpreted languages could be chosen over compiled languages for the following reasons:
i. Interpreted languages are much more flexible and easier to implement than compiled languages as writing good compilers is not easy.
ii. Since interpreters don't need to convert first to intermediary codes as they execute these codes themselves, programs built with interpreters tend to be platform independent.
management is as old as human civilization. justify this statement
Answer:
Indeed, management is as old as the human species, as human nature is itself dependent on the natural resources that it needs for its subsistence, therefore needing to exercise a correct administration of said resources in such a way as to guarantee that those resources can satisfy the greatest number of individuals. That is, the human, through the correct management of resources, seeks to avoid the scarcity of them.

Discuss at least 1 Microsoft Windows security features that could protect data?
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.

Answer:
.isLeapYear (1900) will return an incorrect response
Explanation:
Given
The above method
Required
Which method call will give an incorrect response
(a) will return an incorrect response because 1900 is not a leap year.
When a year is divisible by 4, there are further checks to do before such year can be confirmed to be a leap year or not.
Since the method only checks for divisibility of 4, then it will return an incorrect response for years (e.g. 1900) that will pass the first check but will eventually fail further checks.

You trained a binary classifier model which gives very high accuracy on thetraining data, but much lower accuracy on validation data. The following maybe true:
a. This is an instance of overfitting.
b. This is an instance of underfitting.
c. The training was not well regularized.
d. The training and testing examples are sampled from different distributions.
Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.
