We want to buy the car depending on its cost for 10 years. Here is the algorithm for deciding which car to buy depend a price of OMR 4.000 per liter of gas and usage of 15,000 kilometers per year. For each car, compute the total cost as follows: annual fuel consumed = annual miles driven / fuel efficiency annual fuel cost = price per gallon x annual fuel consumed operating cost = 10 x annual fuel cost total cost = purchase price + operating cost If total cost1 < total cost2 Choose car1. Else if total cost1 > total cost2 Choose car2. Else Choose car1 or car2

If you have been given the full amount required and the list represents the amount of change in your pocket, decide whether you can afford the item or not. Change will always be represented as follows: quarters, dimes, nickels, pens. Illustration: change Enough ([25, 20, 5, 0], 4.25) should prove true, as having 25 quarters, 20 dimes, 5 nickels and 0 pens gives you 6.25 + 2 + .25 + 0 = 8.50.

In a hypothetical study of population dynamics, scientists have been tracking the number of rabbits and foxes on an island. The number of rabbits and foxes are determined once a year using high resolution infrared cameras and advanced computer vision methods.Each year, the number of rabbits and foxes are found to change by the following equations: $$ {\Delta}R = round( kr*R - krf*R*F ) $$ $$ {\Delta}F = round( -kf*F + kfr*R*F ) $$ where $ {\Delta}r $ and $ {\Delta} f $ are the changes in number of rabbits and foxes by the end of that year; and R and F are the population sizes at the end of the previous year. kr, krf, kf, kfr are coefficients that depend on the species of rabbits and foxes.With these dynamics, the scientists realize that one or both species can become extinct on the island. At the end of each year, if there are fewer than 2 animals of a kind, the scientists transfer rabbits and/or foxes to make sure there are at least 2 of each kind.Write a function…
Using pyhton coding to solve: Suppose the Great Frederick Fair wants to update its ticketing software. They need you to write a program to handle the price calculations, using the rules*: ● The basic price of a ticket is $40. Senior citizens (age >= 65) get a 50% discount. Children under 6 are free (100% discount). For residents of Frederick County, the basic price is $35; the same discounts still apply. So the individual ticket prices range from $0 to $40. ● . Your program should request age and county name from the user. The age will be entered as an integer and the county name as a string. Before calculating the price, confirm that the user's age is valid - not negative and not more than 110. If it is not, give a message and do not do the price calculation. Also, the county name should not be case sensitive - for example, Frederick, frederick, and FREDERICK should all be acceptable. Your program should then calculate and print out the ticket price, using the appropriate…
Imagine playing a number guessing game. A side is a number from 0 to Nhe's holding it, and the other side is trying to find that number by taking turns guessing. Number-holding side estimatehe has to offer one of the following three options in response to the party that did it:1-Your guess is correct, you found the number I kept (Game Over).2-Your estimate is wrong, but you are closer to the correct estimate than the previous estimate.3-the wrong estimate and the correct estimate are further away than the previous estimate.To find the estimated number in an environment where all the information is these, astrategy will be followed: Make a prediction (N/2) from the exact middle of N with 1 Begin:Find out the answer to your guess. [answer=answer_ogren (guess)]If the answer is equal to 1, the game is over, you can leave.If the answer is equal to 2, you are going in the right direction, keep the forecast direction;If you're heading for small numbers, the new N is now N/2.Make a guess…
Employees of KB and SONS Consultants Limited are paid at an hourly basics of 25GHS per an hour for regular hours and 1.5 times per hour for overtime hours in a week. Any hour worked over 40 hours per week is overtime. The following national tax sliding scale is then applied to determine the amount of tax to be paid by an employee. GrossWage Tax Rate (%) First 125 0 Next 125 5 Next 1500 10 Next 2750 15 Next 1250 20 Excess over 5000 30 In addition 6% of an employee’s gross wage is withheld for Social Security, 3% is withheld as constituency tax and 20GHS is withheld by the employer as welfare contribution. If an employee has more than 3 dependants then an amount of 5GHS for each dependant in excess of three towards NHIS. You are required to write a program that compute a workers gross pay, the deductions and his/her net pay. Your program should allow details of the staff to be accept /input into the system for the necessary computations. Try using comments in explaining the flow of the…
Sam is a competitive swimmer that competes in the 100 m freestyle and 100 m backstroke. High school swimming state averages are as follows: Freestyle: mean time 72.39 seconds, standard deviation 3.7 seconds Backstroke: mean time 81.09 seconds, standard deviation 4.1 seconds If Sam's times were 71.1 seconds in freestyle and 80.1 seconds in backstroke, select the correct words to describe how his times compare to each other. Since the z-score in freestyle is ["", ""] than the z-score in backstroke, his time in freestyle is ["", ""] when compared to the rest of the swimmers in that event.
In a row of seats, 1 represents a person sitting in that seat, and 0 represents that the seat is empty. There is at least one empty seat, and at least one person sitting. Alex wants to sit in the seat such that the distance between him and the closest person to him is maximized. Return that maximum distance to closest person. A. Example 1: i. Input: [1, 0, 0, 0, 1, 0, 1] ii. Output: 2 • Explanation: • If Alex sits in the second open seat (seats[2]), then the closest person has distance 2. • If Alex sits in any other open seat, the closest person has distance 1. • Thus, the maximum distance to the closest person is 2.
