Which version of Microsoft Office is free?
Answer:
the older versions and really all of them are
Answer:
This is what I found on the internet that I hope will help you! :3
Explanation:
It's a free app that will be preinstalled with Windows 10, and you don't need an Office 365 subscription to use it. The existing My Office app has many of these features, but the new Office app puts the focus on the free online versions of Office if you're not an Office 365 subscriber.
Consider the following method, remDups, which is intended to remove duplicate consecutive elements from nums, an ArrayList of integers. For example, if nums contains {1, 2, 2, 3, 4, 3, 5, 5, 6}, then after executing remDups(nums), nums should contain {1, 2, 3, 4, 3, 5, 6}.
public static void remDups(ArrayList nums)
{
for (int j = 0; j < nums.size() - 1; j++)
{
if (nums.get(j).equals(nums.get(j + 1)))
{
nums.remove(j);
j++;
}
}
}
The code does not always work as intended. Which of the following lists can be passed to remDups to show that the method does NOT work as intended?
A. {1, 1, 2, 3, 3, 4, 5}
B. {1, 2, 2, 3, 3, 4, 5}
C. {1, 2, 2, 3, 4, 4, 5}
D. {1, 2, 2, 3, 4, 5, 5}
E. {1, 2, 3, 3, 4, 5, 5}
Answer:
B. {1, 2, 2, 3, 3, 4, 5}
Explanation:
Given
The above code segment
Required
Determine which list does not work
The list that didn't work is [tex]B.\ \{1, 2, 2, 3, 3, 4, 5\}[/tex]
Considering options (A) to (E), we notice that only list B has consecutive duplicate numbers i.e. 2,2 and 3,3
All other list do not have consecutive duplicate numbers
Option B can be represented as:
[tex]nums[0] = 1[/tex]
[tex]nums[1] = 2[/tex]
[tex]nums[2] = 2[/tex]
[tex]nums[3] = 3[/tex]
[tex]nums[4] = 3[/tex]
[tex]nums[5] = 4[/tex]
[tex]nums[6] = 5[/tex]
if (nums.get(j).equals(nums.get(j + 1)))
The above if condition checks for duplicate numbers.
In (B), when the elements at index 1 and 2 (i.e. 2 and 2) are compared, one of the 2's is removed and the Arraylist becomes:
[tex]nums[0] = 1[/tex]
[tex]nums[1] = 2[/tex]
[tex]nums[2] = 3[/tex]
[tex]nums[3] = 3[/tex]
[tex]nums[4] = 4[/tex]
[tex]nums[5] = 5[/tex]
The next comparison is: index 3 and 4. Meaning that comparison of index 2 and 3 has been skipped.
This is so because of the way the if statement is constructed.
There are different kinds of ArrayList of integers. The option in the lists can be passed to remDups to show that the method does not work as intended is {1, 2, 2, 3, 3, 4, 5}.
When you study the different options given, one will see that that only list B has repeated duplicate numbers such as 2,2 and 3,3. while the other options have only a duplicate numbers that are not following each other.In Python, there are different ways to remove duplicates from list. An example using naive or novice method is;
The main list is : [1, 3, 5, 6, 3, 5, 6, 1]
The list after deleting duplicates : [1, 3, 5, 6]

I don't get the width and height part (PLEASE HELP WILL GIVE BRAINLIEST ANSWER)
Answer:
What they're saying is that the first two bytes (first two eight bit segments) tell you the width and height of the pattern.
In the example given, you'll notice that the first 16 digits are 00000100 00000100. If you convert those to decimal, you'll see that those are both equal to four.
If instead the second block of eight bits was 00000111, the image height would then be seven.
Write a program that declares and initializes a variable representing the weight in milligrams from the keyboard. The program displays the equivalent weight in kilograms, grams, and milligrams. For example, 1050042 milligrams are equivalent to 1 kilogram, 50 grams, and 42 milligrams.
Answer:
weight = int(input("Enter weight in milligrams: "))
kilograms = int(weight / 1000000)
grams = int((weight - (kilograms * 1000000)) / 1000)
milligrams = weight - ((kilograms * 1000000) + (grams * 1000))
print("{} milligrams are equivalent to {} kilogram(s), {} gram(s), and {} milligram(s)".format(weight, kilograms, grams, milligrams))
Explanation:
*The code is in Python.
Ask the user to enter the weight and set it to the variable weight
Calculate the kilograms, divide the weight by 1000000 and cast the result to the int (If the weight is 1050042, kilograms would be 1050042/1000000 = 1)
Calculate the grams, subtract the kilograms from the weight, divide it by 1000 and cast the result to the int (If the weight is 1050042, grams would be int((1050042 - (1 * 1000000)) / 1000) = 50)
Calculate the milligrams, subtract the kilograms and grams from the weight (If the weight is 1050042, milligrams would be 1050042 - ((1 * 1000000) + (50 * 1000)) = 42)
Print the weight, kilograms, grams, and milligrams in the required format
In this exercise we have to use the knowledge of the python language to write the code, so we have to:
The code is in the attached photo.
Some important information informed in the statement that we have to use in the code is:
Calculate the kilograms, divide the weight by 1000000 and cast the result.Calculate the grams, subtract the kilograms from the weight, divide it by 1000 and cast the result.Calculate the milligrams, subtract the kilograms and grams from the weight.So to make it easier the code can be found at:
weight = int(input("Enter weight in milligrams: "))
kilograms = int(weight / 1000000)
grams = int((weight - (kilograms * 1000000)) / 1000)
milligrams = weight - ((kilograms * 1000000) + (grams * 1000))
print("{} milligrams are equivalent to {} kilogram(s), {} gram(s), and {} milligram(s)".format(weight, kilograms, grams, milligrams))

The Boolean Foundation hosted a raffle to raise money for charity and used a computer program to notify the participants about the results. Unfortunately, the program they used was not very robust and all 250 participants received an email telling them that they won... and that their name is Shauna.
Improve this program by writing a function called sendEmail to print a personalized email to stdout. The function should take three parameters:
The name of the recipient
The prize for the raffle
Whether or not the recipient won
Use the email template from the existing program.
#include
using namespace std;
int main() {
cout << "Dear Shauna," << endl;
cout << "You are the winner of our raffle for charity." << endl;
cout << "The prize was: a stuffed giraffe toy" << endl;
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;
return 0;
}
Answer:
The function is as follows:
void sendEmail(string name, string prize, string win_lose){
cout << "Dear "<<name<<", " << endl;
cout << "You are the "<<win_lose<<" of our raffle for charity." << endl;
cout << "The prize was: "<<prize<< endl;
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;
}
Explanation:
This defines the function along the three parameters
void sendEmail(string name, string prize, string win_lose){
This prints the salutation with the person's name
cout << "Dear "<<name<<", " << endl;
This prints if the person won or lost
cout << "You are the "<<win_lose<<" of our raffle for charity." << endl;
This prints the prize, if any
cout << "The prize was: "<<prize<< endl;
The following is the closing remark
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;

Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of 1.0E9 and has an execution time of 1.1 s, while compiler B results in a dynamic instruction count of 1.2E9 and an execution time of 1.5 s. a. Find the average CPI for each program given that the processor has a clock cycle time of 1 ns.
Answer:
The answer is "1.25"
Explanation:
[tex]{CPU \ time}= {instructions \times CPI \times cycle\ time}[/tex]
[tex]\therefore\\\CPI= \frac{CPU \ time}{instructions \times cycle \ time} \\\\cycle \ time = 1 \\\\ns = 10^{-9} s \\[/tex]
Also for this context, it executes the time = CPU time. So, the compiler A, we has
[tex]CPI_{A}= \frac{CPU \ time_{A}} {instructions_{A} \times cycle \ time}= \frac{1.1 s}{10^{9} \times 10^{-9} s}= 1.1[/tex]
For compiler B, we have
[tex]CPI_{B}= \frac{CPU \ times_{B}} {instructions_{B} \times cycle \ time}[/tex]
[tex]= \frac{1.5\ s}{ 1.2 \times 10^{9} \times 10^{-9} \ s}\\\\= \frac{1.5}{ 1.2 }\\\\= 1.25[/tex]
The average CPI for each program given that the processor has a clock cycle time of 1 ns is : 1.1, 1.25.
Average CPI for each programCPI (Complier A)=CPU time/Instruction×Cycle time
Where:
Cycle time=1ns=10^-9s
Hence:
CPI (Complier A)=1.1s/10^9×10^-9s
CPI (Complier A)=1.1
CPI (Complier B)=CPU time/Instruction×Cycle time
CPI (Complier B)=1.5s/1.2×10^9×10^-9s
CPI (Complier B)=1.25
Inconclusion the average CPI for each program given that the processor has a clock cycle time of 1 ns is : 1.1, 1.25.

Answer:
HTML, XML and SGML are the markup languages (hence the "ML" suffix on each of their acronyms).
PHP, ASP and Javascript are scripting languages.
A kind of markup language is HTML. It "marks up" or encapsulates data using HTML tags that specify the data and explain how it will be used on the webpage. Following that, the web browser examines the HTML, which instructs it as to what sections are headings, paragraphs, links, etc.
What are the different web development languages?OOP scripting is used in Java, whereas OOP programming is used in Java. JavaScript code can only be run on a browser, while Java applications can run on a virtual machine or browser.
While JavaScript code is completely in text, Java code must be compiled. They both need various plug-ins.

Explanation:
In this assignment, you will implement an online banking system. Users can sign-up with the system, log in to the system, change their password, and delete their account. They can also update their bank account balance and transfer money to another user’s bank account.
You’ll implement functions related to File I/O and dictionaries. The first two functions require you to import files and create dictionaries. User information will be imported from the "users.txt" file and account information will be imported from the "bank.txt" file. Take a look at the content in the different files. The remaining functions require you to use or modify the two dictionaries created from the files.
Each function has been defined for you, but without the code. See the docstring in each function for instructions on what the function is supposed to do and how to write the code. It should be clear enough. In some cases, we have provided hints to help you get started.
def import_and_create_dictionary(filename):
'''
This function is used to create a bank dictionary. The given argument is the filename to load.
Every line in the file will look like
key: value
Key is a user's name and value is an amount to update the user's bank account with. The value should be a
number, however, it is possible that there is no value or that the value is an invalid number.
What you will do:
- Try to make a dictionary from the contents of the file.
- If the key doesn't exist, create a new key:value pair.
- If the key does exist, increment its value with the amount.
- You should also handle cases when the value is invalid. If so, ignore that line and don't update the dictionary.
- Finally, return the dictionary.
Note: All of the users in the bank file are in the user account file.

Let A and B be two stations attempting to transmit on an Ethernet. Each has a steady queue of frames ready to send; A’s frames will be numbered ????1, ????2 and so on, and B’s similarly. Let T = 51.2 ????????????c be the exponential backoff base unit. Suppose A and B simultaneously attempt to send frame 1, collide, and happen to choose backoff times of 0 × T and 1 × T, respectively. As a result, Station A transmits ????1 while Station B waits. At the end of this transmission, B will attempt to retransmit ????1 while A will attempt to transmit ????2. These first attempts will collide, but now A backs off for either 0 × T or 1 × T (with equal probability), while B backs off for time equal to one of 0 × T, 1 × T, 2 × T and 3× T (with equal probability).(a) Give the probability that A wins this second backoff race immediately after his first collision.(b) Suppose A wins this second backoff race. A transmits ????2 and when it is finished, A and B collide again as A tries to transmit ????3 and B tries once more to transmit ????1. Give the probability that Awins this third backoff race immediately after the first collision.(c) What is the probability that A wins all the ???? backoff races. (???? is a given constant)(d) Assume that there are 3 stations sharing the Ethernet. Will the chance for A to win all the backoffraces decrease or increase? Why?
Answer:
Following are the solution to the given question:
Explanation:
Please find the complete and correct question in the attachment file.
For Point a:
For the second round,
A is selects kA(2) either 0 or 1, so for each of them, that is [tex]\frac{1}{2}[/tex].
B selects [tex]kB(2)\ from\ (0, 1, 2, 3)[/tex] for each choice with the probability of [tex]\frac{1}{4}[/tex].
If [tex]kA(2) < kB(2)[/tex] wins the second rear race.
[tex]\to P[A \ wins] = P[kA(2) < kB(2)][/tex]
[tex]= P[kA(2) = 0] \times P[kB(2) > 0] + P[kA(2) = 1] \times P[kB(2) > 1]\\\\= \frac{1}{2} \times \frac{3}{4} + \frac{1}{2} \times \frac{2}{4} \\\\=\frac{3}{8} +\frac{2}{8} \\\\= \frac{3+2}{8}\\\\= \frac{5}{8}[/tex]
For Point b:
Throughout this example, [tex]kA(3)[/tex] also selects to be either 0 or 1 with such a [tex]\frac{1}{2}[/tex] probability. So, although B chooses [tex]kB(3)[/tex] from [tex](0, 1, 2, 3, 4, 5, 6, 7),[/tex] the probabilities each are [tex]\frac{1}{8}[/tex]:
[tex]\to P[A \ wins] = P[kA(3) < kB(3)][/tex]
[tex]= P[kA(3) = 0] \times P[kB(3) > 0] + P[kA(3) = 1] \times P[kB(3) > 1]\\\\= \frac{1}{2} \times \frac{7}{8} + \frac{1}{2} \times \frac{6}{8}\\\\= \frac{7}{16} + \frac{6}{16}\\\\= \frac{7+6}{16} \\\\= \frac{13}{16}\\\\[/tex]
For point c:
Assume that B tries again 16 times (typical value), and it destroys. In addition, throughout the exponential background n is obtained at 10 when choosing k between 0 to 2n−1. The probability of A winning all 13 backoff events is: [tex]P[A \text{wins remaining races}] = 16\pi i =4P[A \ wins \ i |A \ wins \ i -1 ][/tex]
Let the k value kA(i) be A for the backoff race I select. Because A retains the breed
[tex]=(kA(i)] \cdot P[kA(i+ 1)< kB(i+ 1)] \geq P[kA(i) + 1<kB(i)] \cdot P[kA(i+ 1)< kB(i+1)]+P[kA(i) + 1 \geq kB(i)] \cdot P[kA(i+ 1)< kB(i+ 1)] \\\\= (P[kA(i) + 1< kB(i)] +P[kA(i) + 1 \geq kB(i)]) \times P[kA(i+ 1) < kB(i+ 1)]\\\\=P[kA(i+ 1)< kB(i+ 1)]\\\\[/tex]
For point d:
Two stations A and B are supposed. They assume that B will try 16 times afterward. Even so, for A, 16 races were likely to also be won at a rate of 0.82 For Just higher expectations of three A, B, and C stations. For Station A, possibility to win all backoffs

Concentrate strings
Write code that concatenates the character strings in str1 and str2, separated by a space, and assigns the result to a variable named joined. Assume that both string variables have been initialized.
Two Letters in Word
Given a character string stored in a variable called word, write code that concatenates the fifth character of the word to the third character from the end of the word, and assigns that string to a variable named two_letters. Assume that word already has a value and is at least five characters long.
Set the Number of Cards if Necessary
Write code that sets the value of the variable num_cards to seven if its current value is less than seven. Otherwise, don't change the value. Assume that nuncards already has an initial value.
Answer:
In Python:
(a) Concatenate strings:
joined = str1+" "+str2
(b) Two Letters in Word :
two_letters = word[4]+word[-3]
(c) Set Numbers in Card
if num_cards < 7:
num_cards = 7
Explanation:
The code segments were written in Python
All variables were assumed to have been initialized
Solving (a): Concatenate strings:
To do this, we make use of + operator.
So, the concatenation of str1 and str2 with space in between is
str1+" "+str2
When assigned to variable joined, it becomes
joined = str1+" "+str2
Solving (b): Two Letters in Word :
The character at the 5th position is represented with index 4 i.e. word[4]
To access a character from the end, we make use of - sign. So, the third character from the end is word[-3]
Concatenate them using + operator.
So, we have:
two_letters = word[4]+word[-3]
Solving (c): Set Numbers in Card
Here, we make use of the if condtion.
First, check if num_cards is less than 7(i.e. num_cards < 7)
If true, assign num_cards to 7
So, we have:
if num_cards < 7:
num_cards = 7

Suppose a program contains 500 million instructions to execute on a processor running on 2.2 GHz. Half of the instructions takes 3 clock cycles to execute, where rest of the instructions take 10 clock cycle. What is the execution time of the program
Answer:
1.48 s
Explanation:
Number of instructions = 500 million = 500 * 10⁶
clock rate = 1 / 2.2 GHz = 1 / (2.2 * 10⁹ Hz) = 0.4545 * 10⁻⁹ s
We need to compute the clocks per instruction (CPI)
The CPI = summation of (value * frequency)
CPI = (50% * 3 clock cycles) + (50% * 10 clock cycles)
CPI = (0.5 * 3) + (0.5 * 10) = 1.5 + 5 = 6.5
Execution time = number of instructions * CPI * clock rate
Execution time = 500 * 10⁶ * 6.5 * 0.4545 * 10⁻⁹ =1.48 s
