When an item is gray that means...
A. The item only works with another application
B. The item has been selected
C. The item is unavailable
D. The item has been deleted
A,B,C,orD, can anyone please help?
Answer:
B. The item has been selected
Answer:
C
Explanation:
When an item is unavailable, usually referring to the Technology field, it is gray. Gray items are things that are not created anymore, sold out or not enough supply. The color gray is usually used to symbol something bad, and not having a product is considered bad. Using our background knowledge, we can concude that the answer is option C.
In Python, you can specify default arguments by assigning them a value in the function definition.
Answer:
use the input function to ask them their name like name = input(" enter name?: ") or
def greet(name, msg):
# This function greets to the person with the provided message
print("Hello", name + ', ' + msg)
greet("Andy", "Good morning!")
def greet(name, msg="Good morning!"):
# This function greets to
the person with the
provided message.
If the message is not provided,
it defaults to "Good
morning!
print("Hello", name + ', ' + msg)
greet("Kate")
greet("Bruce", "How do you do?")

High-level modulation is used: when the intelligence signal is added to the carrier at the last possible point before the transmitting antenna. in high-power applications such as standard radio broadcasting. when the transmitter must be made as power efficient as possible. all of the above.
Answer:
Option d (all of the above) is the correct answer.
Explanation:
Such High-level modulation has been provided whenever the manipulation or modification of intensity would be performed to something like a radio-frequency amplifier.Throughout the very last phase of transmitting, this then generates an AM waveform having relatively high speeds or velocity.Thus the above is the correct answer.
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();
A buffer is filled over a single input channel and emptied by a single channel with a capacity of 64 kbps. Measurements are taken in the steady state for this system with the following results:
Average packet waiting time in the buffer = 0.05 seconds
Average number of packets in residence = 1 packet
Average packet length = 1000 bits
The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential.
Required:
What are the average arrival rate λ in units of packets/second and the average number of packets w waiting to be serviced in the buffer?
Answer:
a) 15.24 kbps
b) 762 bits
Explanation:
Using little law
a) Determine the average arrival rate ( λ ) in units of packets/s
λ = r / Tr --- 1
where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 )) = 0.0656
back to equation 1
λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps
b) Determine average number of packets w to be served
w = λ * Tw = 15243.9 * 0.05 = 762.195 ≈ 762 bits

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:
war driving.
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 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
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.

C++Assign to maxSum the max of (numA, numB) PLUS the max of (numY, numZ). Use just one statement. Hint: Call FindMax() twice in an expression.#include using namespace std;double FindMax(double num1, double num2) { double maxVal; // Note: if-else statements need not be understood to complete this activity if (num1 > num2) { // if num1 is greater than num2, maxVal = num1; // then num1 is the maxVal. } else { // Otherwise, maxVal = num2; // num2 is the maxVal. } return maxVal;}int main() { double numA; double numB; double numY; double numZ; double maxSum; cin >> numA; cin >> numB; cin >> numY; cin >> numZ; /* Your solution goes here */ cout << "maxSum is: " << maxSum << endl; return 0;}
Answer:
Replace the comment with:
maxSum =FindMax(numA,numB)+FindMax(numY,numZ);
Explanation:
Required
The statement to add up the two maximum from the functions
To do this, we have to call FindMax for both arguments i.e.
FindMax(numA,numB) and FindMax(numY,numZ) respectively
Next, use the + sign to add up the returned value.
So, the complete statement is:
maxSum =FindMax(numA,numB)+FindMax(numY,numZ);

Consider the following class, which uses the instance variable balance to represent a bank account balance.
public class BankAccount {
private double balance;
public double deposit(double amount) {
/* missing code */
}
}
The deposit method is intended to increase the account balance by the deposit amount and then return the updated balance. Which of the following code segments should replace /* missing code */ so that the deposit method will work as intended?
a.
amount = balance + amount;
return amount;
b.
balance = amount;
return amount;
c.
balance = amount;
return balance;
d.
balance = amount;, , return balance;,
balance = balance + amount;
return amount;
e.
balance = balance + amount;
return balance;
Answer:
e.
balance = balance + amount;
return balance;
Explanation:
Required
Code to update account balance and return the updated balance
The code that does this task is (e).
Assume the following:
[tex]balance = 5000; amount = 2000;[/tex]
So, code (e) is as follows:
balance = balance + amount; [tex]\to[/tex]
[tex]balance = 5000 + 2000[/tex] [tex]\to[/tex]
[tex]balance = 7000[/tex]
Here, the updated value of balance is 7000
So: return balance
will return 7000 as the updated account balance

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)

Given the declaration: char a[] = "Hello"; char *p = a, *q; what operations are valid syntactically? Select all that apply. Group of answer choices q = &&a[0]; q = &&a; *q = *(&a[0]); q = &(*p);
Answer:
The valid operations are:
*q = *(&a[0]); and q = &(*p);
Explanation:
Given
The above declarations
Required
The valid operations
*q = *(&a[0]); and q = &(*p); are valid assignment operations.
However, q = &&a[0]; q = &&a; are invalid because:
The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.
Hence, *q = *(&a[0]); and q = &(*p); are valid
Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler
What are the basic characteristics of the linear structure in data structure
Explanation:
A Linear data structure have data elements arranged in sequential manner and each member element is connected to its previous and next element. This connection helps to traverse a linear data structure in a single level and in single run. Such data structures are easy to implement as computer memory is also sequential.
Assume that a file contains students’ ids, full names, and their scores (Assignments grade, quizzes grade, Midterm grade, Practical exam grade, and final exam grade) (each column is separated by $). You are required to write a C program to do the following:
• Using the concept of parallel arrays create records for students with above attributes (id, full name, score).(you are not allowed to use structure)
• Ask the user to enter the input file name and read it (suppose that, there are different files you could read data from). Read the data from the file and store it in record for students, which has IDs, Names, and Scores. The IDs should be declared as integers, the Names as a two-dimensional array of characters and the Scores as doubles. Assume that the maximum length of full name of any student is 50 characters. Also, you may assume that there will be No more than a 1000 student records in the file.
• Calculate the final grade as the flowing:
Grade= (Assignment)*15%+(Quizzes) *15%+(Midterm exam) *25%+(Practical Exam)
*10%+(Final) *35% Assuming that data in files are arranged in same order of the above equation with respect to grades
Hint: read form file, calculate the final score, and store it in the record before going to the next step.
• Display the following menu to the user and read the entered choice:
1) Sort data in ascending order according to students’ IDs and then display it.
2) Sort data in ascending order according to students’ names and then display it.
3) Sort data in descending order according to students’ scores and then display it.
Note: After running any of the above menus items, ask the user if he/she would like to save the current result, if so, prompt user to enter file name.
4) Ask the user to enter a student ID and display his score
5) Ask the user to enter a student name and display his score
6) Exit the program
The program should keep displaying the menu until the user selects to exit from the program.
Implement each of the first five menu options as a separate function.

why absolute reference is used in spreadsheet
Absolute reference is used especially to keep the value or content of a column or row constant.
Explanation:Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.
In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.
i. relative referencing
ii. absolute referencing
iii. mixed referencing
Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.
Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.
Mixed reference is a hybrid of the relative and absolute references.

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;
}
