A new office need 16 computer Tables.If a computer tables costs 2,671.How much is needed to purchase 16 computer tables.
Answer:
The total amount needed to purchase the 16 computer tables is 42,736
Explanation:
Given;
Total number of computer tables needed in the new office, n = 16
cost of one computer table, c = 2,671
The total amount needed to purchase the 16 computer tables is calculated as follows;
Total cost of 16 computer tables = cost of one computer table x total number of tables needed
Total cost of 16 computer tables = 2,671 x 16
Total cost of 16 computer tables = 42,736
Therefore, the total amount needed to purchase the 16 computer tables is 42,736

The following question is based on the following incomplete declaration of the class BoundedIntArray and its constructor definitions.
A BoundedintArray represents an indexed list of integers. In a BoundedIntArray the user can specify a size, in which case the indices range from 0 to size - 1. The user can also specify the lowest index, low, in which case the indices can range from low to low + size - 1.
public class BoundedIntArray
{
private int[] myItems; // storage for the list
private int myLowIndex; // lowest index
public BoundedIntArray(int size)
{
myItems = new int[size];
myLowIndex = 0;
}
public BoundedIntArray(int size, int low)
{
myItems = new int[size];
myLowIndex = low;
}
// other methods not shown
}
Consider the following statements.
BoundedIntArray arrl = new BoundedIntArray(100, 5);
BoundedIntArray arr2 = new BoundedIntArray(100);
Which of the following best describes arrl and arr2 after these statements?
a.
arrl and arr2 both represent lists of integers indexed from 0 to 99.
arrl and arr2 both represent lists of integers indexed from 0 to 99 . ,
b.
arrl and arr2 both represent lists of integers indexed from 5 to 104.
arrl , and, arr2 , , both represent lists of integers indexed from, 5 , to, 104, .,
c.
arrl represents a list of integers indexed from 0 to 104, and arr2 represents a list of integers indexed from 0 to 99.
arrl , represents a list of integers indexed from, 0 , to, 104, , and, arr2 , represents a list of integers indexed from, 0 , to, 99, ., ,
d.
arrl represents a list of integers indexed from 5 to 99, and arr2 represents a list of integers indexed from 0 to 99.
arrl represents a list of integers indexed from 5 to 99 , and arr2 represents a list of integers indexed from 0 to 99 . ,
Answer:
d.
Explanation:
Using the Java code provided, the creation of the BoundedIntArray objects would be that arrl represents a list of integers indexed from 5 to 99, and arr2 represents a list of integers indexed from 0 to 99. This is because arr1 is passing two arguments when it is being created, the first indicates the array size while the second indicates the lowest index. Since it passes two arguments it overrides the constructor and uses the constructor with two parameters. arr2 only passes one argument so it uses the original constructor which automatically sets the lowest index to 0.
The correct choice in this question is "arr1 is an array of numbers indexed from 5 to 104, while arr2 is an array of integers indexed from 0 to 99".
Array number:arr1 is for numbers 5 to 104, whereas arr2 is for numbers 0 to 99.Since the lowest index in arr1 is transmitted, it should be 5, and the array size should be 100. The index of the last member inside an array is also (size-1) since the array's lowest index is inclusive.Furthermore, arr2 is for 0 to 99, so because size, which would be 100, if passed, the lowest index is not. As a result, the lowest index by default is 0.Find out more about the Array here:

my code get an input of 1900 and it should output not a leap year but it fails first line of code. It should output not a Leap any number with 1500 not divisble by 4 with/out a remainder should output (not a leap year. )
input_year = int(input())
if input_year % 4 == 0: #fails on this step, 1900 should be false
print(input_year, "- is Leap Year")
elif input_year % 100 == 0:
print(input_year, "- leap year")
elif input_year % 400 ==0:
print(input_year, "is a leap year")
else:
print(input_year, "- not a leap year")
Answer:
Explanation:
The code does not fail on the first step since 1900 divided by 4 is actually 475 and has no remainder, meaning that it should return True. The code won't work because the if statements need to be nested in a different format. The correct algorithm would be the following, which can also be seen in the picture attached below that if we input 1900 it would output is not a leap year as it fails on the division by 400 which gives a remainder of 0.75
input_year = int(input())
if input_year % 4 == 0:
if input_year % 100 == 0:
if input_year % 400 == 0:
print(input_year, "is a leap year")
else:
print(input_year, "- not a leap year")
else:
print(input_year, "is a leap year")
else:
print(input_year, "- not a leap year")

Answer:
Cut the Television and related equipment row.Click the plus sign on the left side of the table between the last two rows.Paste the Television and related equipment row.Explanation:
In order to move the row, Tristan should first select the row and then cut it. This will ensure that the row will be moved completely instead of copied.
Tristan should then hover with the mouse between the last two rows and click on the plus sign on the left side. It will add a new row to the sheet. between the last two rows.
Tristan should then select the topmost cell and click paste. The television row will be pasted there and Tristan would have successfully moved it.

Write a function, AvgList, that takes a single argument, a list, and returns the average (mean) of the numbers in the list. You may assume that all elements of the list are numeric (int or float), and that the list has at least one element. Hints: Use the function SumList that you wrote above. Use the built-in function len to get the number of elements in the list.
Answer:
Answered below
Explanation:
//Programmed in Java
public double avgList(int [] nums){
int I;
double sumOfNumbers = 0;
double averageOfNumbers = 0;
//Loop over to sum all elements in the list.
for(I = 0; I < nums.length; I++){
sumOfNumbers += nums[I];
}
//Calculate the average
averageOfNumbers = sumOfNumbers/ nums.length;
return averageOfNumbers;
}
Write a template that accepts an argument and returns its absolute value. The absolute entered by the user, then return the total. The argument sent into the function should be the number of values the function is to read. Test the template in a simple driver program that sends values of various types as arguments and displays the results.
Answer:
In python:
The template/function is as follows:
def absval(value):
return abs(value)
Explanation:
This defines the function
def absval(value):
This returns the absolute value of the argument using the abs() function
return abs(value)
To call the function from main, you may use:
print(absval(-4))

Thus, A language that is neither an official language of a nation nor one that is often spoken there is referred to as a foreign language. Typically, native speakers from that country must study it consciously, either through self-teaching, taking language classes, or participating in language sessions at school.
However, there is a difference between learning a second language and learning a foreign language.
A second language is one that is widely used in the area where the speaker resides, whether for business, education, government, or communication. In light of this, a second language need not be a foreign language.

Suppose Alice downloads a buggy browser that implements TLS incorrectly. The TLS specification says that, during the handshake, the browser should send a random 256-bit number RB. Instead of picking RB randomly the browser always sends all zeros. Describe an attack that is possible against this buggy browser and how to update the browser so that this attack is no longer feasible.
Solution :
It is given that Alice downloads the buggy browser which implements a TLS incorrectly. The specification of a TLS states that during a handshake, the browser sends a 256 bit number of RB randomly.
So in this case, a man-n-the-middle attack is possible. It can compromise the confidentiality of Alice. Updating the browser by visiting the website and checking its latest version of the browser or installing some other browser which has a more trust in the market for its security features.

Thus, English has three tenses: past, present, and future. When writing about the past, we employ the past tense.
When writing about facts, opinions, or regular occurrences, we employ the present tense. To write about upcoming events, we utilize the future tense. Each of those tenses has additional characteristics, but we won't cover them in this session.
It's crucial to maintain the same tense throughout a writing endeavor after you've decided on one. To communicate yourself clearly, you may need to switch up the tense from time to time.
