Concept explainers
(World Population Growth) World population has grown considerably over the centuries. Continued growth could eventually challenge the limits of breathable air, drinkable water, arable cropland and other limited resources. There’s evidence that growth has been slowing in recent years and that world population could peak some time this century, then start to decline.
For this exercise, research world population growth issues online. Be sure to investigate various viewpoints. Get estimates for the current world population and its growth rate (the percentage by which it’s likely to increase this year). Write a
The first column should display the year from year 1 to year 75. The second column should display the anticipated world population at the end of that year. The third column should display the numerical increase in the world population that would occur that year. Using your results, determine the year in which the population would be double what it is today, if this year’s growth rate were to persist.

- Can u solve this ?arrow_forward(CLO3) Read the following description and answer the following questions about it: Problem Description: A car dealership allows customer to purchase their new cars with different options. At this time, those options are color, model, and air condition, as shown below in class CustomerOrder. Of course, the dealership wants the software to be flexible enough to be able to add more options in the future, if needed. CustomerOrder -carColor: String -carModel: String -hasAirCondition: boolean Q1) Write the full required code in Java to use the Builder design pattern to create class CustomerOrder. Q2) Write a Java main() method to create an object of class CustomerOrder with color "red" and without air condition.arrow_forwardQ3: Interplanetary Spaceflight Milan Tusk is the richest person in the universe. After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…arrow_forward
- Transcribed Image Text 7-a) Danish works as a constructor. Like all constructors, he is also a beer fan. He likes beer so much that has K cups of beer daily. However, having more than K cups doesn't suit him, because the excess beer won't allow him to sleep at night. Danish's working day is divided into N periods. For every period, he knows how many kilobytes of weight he can lift. During each of the periods, Danish can either have or not to have one bottle of beer. If he is having a bottle of beer in some period, the amount of work in this period drops to zero. But he also gets a productivity boost, if he decides to skip beer during a period and the last bottle of beer, he had was no more than D periods ago, the amount of work during such a period is M times the usual.arrow_forwardIn c++.

Provide explanation as well. Thank you. Write a program that keeps track of running piggybank deposits. The program should receive input from a user that will enter the amount to deposit into the piggybank. Use a function, add, which takes an argument number from the user input and adds it to a global sum variable. After the 5th deposit, print out the running total thus far.arrow_forwardkindly change the program following the procedure on the problem. please list the changes you have made on the program t..thank youarrow_forward
- Write a software that generates an array of 100 random integers in the range 1 to 200 and then scans the array 100 times with randomly created goals in the same range using sequential scan. The following figures will be shown at the conclusion of the programme. (Director of Operations) The total number of searches that have been done.The total number of searches that were active.The number of searches that were effective.Per quest, the average number of evaluations.Note: You must count the amount of tests for each quest to calculate the average test per search. To count the comparisons, use the comma operator.arrow_forwardProgram Specifications Write a FancyCar class to support basic operations such as drive, add gas, honk horn and start engine. fancy_car.py is provided with function stubs. Follow each step to gradually complete all instance methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main program includes basic calls to the instance methods. Add statements in the main program as instance methods are completed to support development mode testing. **Step 0: Complete the constructor to initialize the model and miles per gallon (MPG) with the values of the parameters. Initialize the odometer to five miles and the tank to be full of gas. By default, the model is initialized to "Old Clunker", and MPG is initialized to 24.0. Note the provided constant variable indicates the gas tank capacity of 14.0 gallons. Step 1 Complete the instance…arrow_forwardCan you give example for each please?arrow_forward
