(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 precious resources. There is evidence that growth has been slowing in recent years and that world population could peak sometime this century, then start to decline.
For this exercise, research world population growth issues online. Be sure to investigate viewpoints. Get estimates for the current world population and its growth rate (the percentage by which it is likely to increase this year). Write a

- *Using Python The scientist has 500 cages in which to hold her rabbits. Each cage holds one pair of rabbits. Assuming that no rabbits ever die, when will she run out of cages? Your program must do the following: Print a table that contains the following information for each month. The number of months that have passed. The number adult rabbit pairs (those over 1 month old). The number of baby rabbits pairs produced this month. The total number of rabbit pairs in the lab. Calculate how many months it will take until the number of rabbits exceeds the number of available cages. Stop printing when you run out of cages. Print a message giving how many months it will take to run out of cages Output file should look like the following. Comments in the file begin with '#', and must appear as shown too: Code must contain def main(): #main function need in all programs for automated testing """ Program starts here """ #end of main program if __name__ == '__main__': main() #excucte main…arrow_forwardSummary Interest on a credit card's unpaid balance is calculated using the average daily balance. Suppose that netBalance is the balance shown in the bill, payment is the payment made, d1 is the number of days in the billing cycle, and d2 is the number of days payment is made before billing cycle. Then, the average daily balance is: averageDailyBalance = (netBalance * d1 payme If the interest rate per month is, say, 0.0152, then the interest on the unpaid balance is: interest averageDailyBalance * 0.0152 Instructions Write a program that accepts as input netBalance, d1, payment, d2, and interest rate per month ( interestRate).arrow_forwardIf i receive incorrect solution again then be ready to get dislike and reported.arrow_forward

The task is to identify a celebrity by only asking questions to people of the form: ”Do you know him/her?” Solution Select two people from the group given, say, A and B, and ask A whether A knows B. If A knows B, remove A from the remaining people who can be a celebrity; if A doesn’t know B, remove B from this group. Solve the problem recursively for the remaining group of people who can be a celebrity Which design strategy does the following solution use?

- Exercise B: Some initial values may make the PageRank algorithm converge faster, you can use a program to try different initial values. You can use a smaller floating number precision (fewer decimal places) to converge faster. Or you can assume if the PageRank values change in less than a certain percentage (e.g., 5%), they are converged.arrow_forwardWhat is the return value of “ corona”.

- DO NOT USE EXISTING ANSWERS ON CHEGG OR COURSE HERO OR ANY OTHER SERVICES PLEASE! Thanks :) CODE IN PYTHON AND SHOW COMMENTS TO EXPLAIN CODE A confused Dutchman trying to speak English could say “I am in the war”, even though there is no hostile activity going on. The confusion1 here is that the English sentence “I am confused” is translated in Dutch as “Ik ben in de war”, which is phonetically (“sounding”) quite close to the first sentence. Such confusion leads to much enjoyment, but can complicate matters a bit. Given a sentence in Dutch and a dictionary containing both correct translations as well as phonetic (incorrect) translations of individual words, find the translation of the sentence and indicate whether it is correct, or in case there is more than one find the total number of correct and incorrect translations. A sentence is correctly translated when each word of the sentence is correctly translated. Input The input consists of: One line with an integer n (1≤n≤20), the…arrow_forwardComplete the following sentence.
