Which statement about broadcasting a slideshow online is true?
9966 [12]

Answer: PowerPoint has a free, built-in service for broadcasting online.

Explanation:

The statement that's true about the broadcast of a slideshow online is that PowerPoint has a free, built-in service for broadcasting online.

Option 1 is wrong as all transitions are not properly displayed to the audience when broadcasting online.

Option 2 is wrong as broadcasting as slideshow online is an option for most PowerPoint users.

Option 3 is wrong because when broadcasting online, third party desktop sharing software isn't necessarily an option and it isn't a must that it must be used.

Therefore, the correct option is 4.

larisa [96]

Answer:

<em>The programming language is not stated;</em>

<em>However, the program written in Python is as follows</em>

def solveEquation(x,y,z):

     result = z - y + 2 * x

     print(result)

x = float(input("x = "))

y = float(input("y = "))

z = float(input("z = "))

print(solveEquation(x,y,z))

Explanation:

This line defines the function solveEquation

def solveEquation(x,y,z):

This line calculates the expression in the question

     result = z - y + 2 * x

This line returns the result of the above expression

     print(result)

The next three lines prompts user for x, y and z

x = float(input("x = "))

y = float(input("y = "))

z = float(input("z = "))

This line prints the result of the expression

print(solveEquation(x,y,z))

artcher [175]

Answer:

C++ code is explained below

Explanation:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Variables to store inputs

string robot_name = "Nao";

string visitor_name;

int age, first_num, second_num;

// Constant variable initialisation for programmer name

const string programmer_name = "XXXXXXXX";

// Constant variable initialisation for assignment number

const string assignment_num = "123546";

// Constant variable initialisation for due date

const string due_date = "16 August, 2019";

// Displaying robot's name as script

cout << "Hello, welcome to Montgornery College!";

cout << "My name is " << robot_name << " . May I have your name?" << "\n\n";

// Taking visitor's name as input from the visitor

cin >> visitor_name;

// Displaying vistor's name as script

cout << "\n\nNice to have your with us today, " << visitor_name << "! ";

cout << "Let me impress you with a small game.";

cout << "Give me the age of an important person or a pet to you. ";

cout << "Please give me only a number!" << "\n\n";

// Taking human age as input from the visitor

cin >> age;

// Displaying human's age as script

cout << "\n\nYou have entered " << age << ". If this is for a person,";

cout << " the age can be expressed as " << age << " years or ";

// Computing months, days, hours, minutes and seconds from age input

double months = age*12;

double days = months*30;

double hours = days*24;

double minutes = hours*60;

// Computing dogs and fish age from human's age

double dogs_age = 7*age;

// Displaying months, hours, minutes, hours and seconds as script

cout << months << " months or about " << days << " days or";

cout << " about " << fixed << setprecision(0) << hours << " hours or about " << minutes;

cout << " or about " << fixed << setprecision(0) << seconds << " seconds. If this is for a dog.";

// Displaying dogs age and gold fish age as script

cout << " it is " << dogs_age << " years old in human age.";

cout << " If this is for a gold fish, it is " << gold_fish_age;

cout << " years old in human age" << "\n\n";

cout << "Let's play another game, " << visitor_name << "!";

cout << "Give me a whole number." << "\n\n";

// Taking first whole number from the visitor

cin >> first_num;

cout << "\nVery well. Give me another whole number." << "\n\n";

// Taking second whole number from the vistor

cin >> second_num;

// Computing sum and division for displaying in the script

double sum = first_num+second_num;

double division = first_num/second_num;

float floatDivision = (float)first_num/second_num;

// Displaying sum and division script

cout << "\nUsing the operator '+' in C++,";

cout << " the result of " << first_num << " + " << second_num;

cout << " is " << sum << ". Using the operator '/', the result ";

cout << "of " << first_num << " / " << second_num << " is " << division;

cout << "; however, the result of " << first_num << ".0 /" << second_num;

cout << ".0 is about " << floatDivision << "." << "\n\n";

cout << "Do you like the games, " << visitor_name << "?";

cout << " If you do, you can learn more by taking our classes.";

cout << ". If you don't, I am sad, You should talk to our Chairman!" << "\n\n";

// Displaying Programmer Name, Assignment Number and due date to output screen

cout << "Programmer Name : " << programmer_name << endl;

cout << "Assignment Number : " << assignment_num << endl;

cout << "Due Date : " << due_date << endl;
