Answer: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.
Problem:

Slow Internet.Question 6 Which of the following statements about datasets used in Machine Learning is NOT true? 1 point Testing data is data the model has never seen before and is used to evaluate how good the model is Training subset is the data used to train the algorithm Validation data subset is used to validate results and fine-tune the algorithm's parameters Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is
Answer:
Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is
Explanation:
The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."
This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.
Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.
And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters
JavaAssignmentFirst, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "BackwardsStrings" (without the quotation marks) that:Prompts the user at the command line for one 3-character string.Then (after the user inputs that first 3-character string) prompts the user for another 3-character string.Then prints out the two input strings with a space between them.Finally prints on a separate line the two input strings 'in reverse' (see example below) with a space between them.So, for example, if the first string is 'usr' and the second string is 'bin', your program would output something like the following:The two strings you entered are: usr bin.The two strings in reverse are: nib rsu.Note that the reversed SECOND string comes FIRST when printing the strings in reverse.my result/*Name: Saima SultanaLab:PA - BackwardsStrings (Group 2)*/package backwardsstrings;import java.util.Scanner;public class BackwardsStrings { public static void main(String[] args) { //variables String first, second; // TODO code application logic here StringBuilder firstReversed= new StringBuilder(); StringBuilder secondReversed= new StringBuilder(); Scanner input = new Scanner(System.in); // read strings first=input.nextLine(); second=input.nextLine(); // print out the input strings System.out.println("The two string you entered are:"+ first+" "+second+"."); // reverse the strings for ( int i=first.length()-1;i>=0; i--) firstReversed.append(first.charAt(i)); for ( int i=second.length()-1;i>=0; i--) secondReversed.append(second.charAt(i));// print out the reverse string System.out.println("The two strings in reverse are:"+secondReversed+" "+ firstReversed+ ".");}}
Answer:
Your program would run without error if you declared the first and second string variables before using them:
Modify the following:
first=input.nextLine();
second=input.nextLine();
to:
String first=input.nextLine();
String second=input.nextLine();
Explanation:
Required
Program to print two strings in forward and reversed order
The program you added is correct. The only thing that needs to be done is variable declarations (because variables that are not declared cannot be used).
So, you need to declared first and second as strings. This can be done as follows:
(1) Only declaration
String first, second;
(2) Declaration and inputs
String first=input.nextLine();
String second=input.nextLine();

You are designing an application at work that transmits data records to another building in the same city. The data records are 500 bytes in length, and your application will send one record every 0.5 seconds
Is it more efficient to use a synchronous connection or an asynchronous connection? What speed transmission line is necessary to support either type of connection? Show all your work.
Solution :
It is given that an application is used to transmit a data record form one building to another building in the same city, The length of the data records is 500 bytes. and the speed is 0.5 second for each record.
a). So for this application, it is recommended to use a synchronous connection between the two building for data transfer as the rate data transfer is high and it will require a master configuration between the two.
b). In a synchronous connection, 500 bytes of data can be sent in a time of 0.5 sec for each data transfer. So for this the line of transmission can be either wired or wireless.

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.
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.

Explanation:
if a+1/a=3 find the valie of a^2+1/a^2
Answer:
a² + 1/a² = 7
Explanation:
a + 1/a = 3 ; obtain the value of a² + 1/a²
Taking a + 1/a = 3
Squaring both sides ;
(a + 1/a)² = 3²
(a + 1/a)(a + 1/a) = a² + a/a + a/a + 1/a² = 3²
(a + 1/a)(a + 1/a) = a² + 1 + 1 + 1/a² = 9
a² + 2 + 1/a² = 9
a² + 1/a² = 9 - 2
a² + 1/a² = 7
Hence,
a² + 1/a² = 7

Horizontal Navigation List Styles
Go to the Horizontal Navigation List Styles section. Karen has added a second navigation list that she wants to display horizontally. For all list items within the horizontal navigation list, create a style rule that displays the items as blocks with a width of 12.5% floated on the left margin.
Here is my code:
/* Horizontal Navigation List Styles */
.horizontal li {
display: block;
width: 12.5%;
float: left;
}
It's coming through as just a line and I have no idea how to fix it, please help!
Answer:
Explanation:
The best way to do this would be to use the following line of code
clear: left;
This would make sure that there are no floating elements (li's in this scenario) on the left side of each element. Which in this navigation list would be each individual element, causing it to move each element underneath the previous element. Therefore the entire CSS code would be
.horizontal li {
display: block;
width: 12.5%;
float: left;
clear: left;
}
An example can be seen in the attached picture below.

Suppose that in a 00-11 knapsack problem, the order of the items when sorted by increasing weight is the same as their order when sorted by decreasing value. Give an efficient algorithm to find an optimal solution to this variant of the knapsack problem, and argue that your algorithm is correct.
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.

Why is Java declining in popularity?
Answer:
other languages are increasing in popularity
Explanation:
The simple main reason for this is that other languages are increasing in popularity. There are many open-source languages that are being optimized constantly and upgraded with new features. The ability for these languages to perform many tasks better than Java makes it the obvious choice when a developer is choosing a language to develop their program on. Two of these languages are Javascript and Python. Both can do everything that Java can and with less code, faster, and cleaner.
1. Design pseudocode for a program that will permit a user to store exactly 75 numbers in an array. Create an array big enough to hold the numbers and store each number in the array as it's entered. Be sure to PROMPT the user for each number before it's entered. You do not need to initialize the array. HINTS: Make sure you use a named constant when you declare the array (the number inside the brackets should be a named constant that you declared before the array declaration.) Use a for loop (or while loop if you'd like) to get each number from the user. The module has an example of pseudocode very similar to this problem. You're free to use this pseudocode as you create your program. 2. Identify three advantages of arrays. For each advantage, write at least one complete sentence explaining why the advantage you listed is an advantage. More detail is better. You may use outside resources but be sure to CITE those resources using APA format.
Answer:
Question 1: The pseudocode is as follows:
int n = 70;
int intArray[n];
for(int i = 0; i< n; i++){
print("Input "+(i+1)+": ")
input intArray[i];
}
Question 2: Advantages of array
Indexing in arrays in easyIt can be used to store multiple values of the same typeIt can be used for 2 dimensional inputsExplanation:
Question 1
This declares and initializes the length of the array
int n = 70;
This declares the array
int intArray[n];
This iterates through the length of the array
for(int i = 0; i< n; i++){
This prompts the user for inputs
print("Input "+(i+1)+": ")
This gets input for each element of the array
input intArray[i];
}
Question 2
Indexing: Elements of the array can easily be accessed through the index of the element.
For instance, an element at index 2 of array intArray can be accessed using: intArray[2]
Multiple Values: This is illustrated in question 1 above where we used 1 array to collect input for 70 values.
2 dimensional inputs: Literally, this means that array can be used to represent matrices (that has rows and columns).
An illustration is:
intArray[2][2] = {[0,1],[3,5]}
The above array has 2 rows, 2 columns and 4 elements in total.
you recieve a phone call from the sterlization monitoring company informing you that the last spore test you sent has failed. What should you check to determine the possible cause
Answer: The type sterilization that was used and how well it was performed
Explanation:
If there's a phone call from the sterilization monitoring company that the last spore test sent has failed, to determine the possible cause, I'll have to type sterilization that was used and how well it was performed.
The sterilization technique used will be analysed, and there'll also be a check for possible human errors. Once thus is done, the possible reason for the failure of the last spore that was sent can then be determined.
find the summation of even number between (2,n)
Answer:
The program in python is as follows:
n = int(input("n: "))
sum = 0
for i in range(2,n+1):
if i%2 == 0:
sum+=i
print(sum)
Explanation:
This gets input n
n = int(input("n: "))
This initializes sum to 0
sum = 0
This iterates through n
for i in range(2,n+1):
This checks if current digit is even
if i%2 == 0:
If yes, take the sum of the digit
sum+=i
Print the calculated even sum
print(sum)
A practice in which eavesdroppers drive by buildings or park outside and try to intercept wireless network traffic is referred to as: Group of answer choices cybervandalism. driveby downloading. war driving. sniffing. driveby tapping.
Answer:

Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Generally, the two (2) essential privacy concerns in the field of cybersecurity are knowing how personal data are collected and essentially how they're used by the beneficiaries or end users.
War driving can be defined as a form of cyber attack which typically involves having eavesdroppers in a moving vehicle drive by buildings or park outside so as to avail them the opportunity of intercepting a wireless network traffic using a smartphone or laptop computer and illegitimately obtain sensitive user informations for further unauthorized use or to perform other fraudulent activities.

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.

Kylee needs to ensure that if a particular client sends her an email while she is on vacation, the email is forwarded to a
coworker for immediate handling. What should she do?
O Configure a response for external senders.
O Configure a response for internal senders.
O Only send during a specific time range.
O Configure an Automatic Reply Rule.
Answer:
Configure an Automatic Reply Rule
Explanation:
The Rule feature in Outlook enables a user to respond immediately to a message, to move a message, or to flag a a message.
The Automatic Replies (Out-of-Office) feature can also be used to let colleagues inside the organization know when a user is out of office and the arrangements that they have made
Also, Using the Out-of-Office dialogue box, under the Files tab, Automatic Replies can be configured using the Rules button to add a rule that forwards all messages from the particular client to the email address of a coworker for them to take care of immediate, while sending an automatic reply to the sender about being out of office and that the mail has been forwarded to a coworker to handle
Therefore, Kylee can configure an Automatic Reply Rule
