The fuel economy of a car is the distance which it can travel on one litre of fuel. The base fuel economy (i.e., its fuel economy when there is only one person - the driver - in the car) of a certain car is MM kilometres per litre. It was also observed that every extra passenger in the car decreases the fuel economy by 11 kilometre per litre. PP people want to take this car for a journey. They know that the car currently has VV litres of fuel in its tank. What is the maximum distance this car can travel under the given conditions, assuming that all PP people always stay in the car and no refuelling can be done? Note that among the PP people is also a driver, i.e., there are exactly PP people in the car. Solve in any programming language
Quadratic Root Solver For a general quadratic equation y = ax? + bx + c, the roots can be classified into three categories depending upon the value of the discriminant which is given by b2 - 4ac First, if the discriminant is equal to 0, there is only one real root. Then, if the discriminant is a positive value, there are two roots which are real and unequal. The roots can be computed as follows: -b+ Vb? – 4ac 2a Further, if the discriminant is a negative value, then there are two imaginary roots. In this case, the roots are given by b ь? - 4ас 2a 2a Programming tasks: A text file, coeff.txt has the following information: coeff.txt 3 4 4 4 1 4 Each line represents the values of a, b and c, for a quadratic equation. Write a program that read these coefficient values, calculate the roots of each quadratic equation, and display the results. Your program should perform the following tasks: • Check if the file is successfully opened before reading • Use loop to read the file from main…
A deck of cards contains 52 cards with four suits: club, diamond, heart and spade ranging in values from 2, ... to 10, Jack, Queen, King and Ace. Ace has the highest value in the same suit. Cards can be compared using their face values. A card with higher face value is bigger than a card with lower face value. If two cards have the same face value, then the suit determines the order. Club is smaller than diamond which is smaller than heart which is smaller than spade. For example: club 2 < diamond 2 < heart 2 < spade 2 if compared.Write an interactive Java program that allows you play cards with a computer. For this project, we are going to focus on one suit of the deck of cards. There are only 13 cards (value: 2, ... to 10, Jack, Queen, King and Ace) in a suit. To play:(a). You first pick a suit at random from the four suits (club, diamond, heart and spade), and display the suit. (b) Then you randomly draw a card from the suit, and let computer draw a card from the same…

Club is smaller than diamond which is smaller than heart which is smaller than spade. For example: club 2 < diamond 2 < heart 2 < spade 2 if compared. Write an interactive Java program that allows a user to randomly pick a card from the deck of 52 cards (using a random number between 1 and 4 to represent the four suits: club, diamond, heart and spade and then another random number to represent the face value) to play. Show the suit and face value of the user card. Then the program acts as a card dealer which randomly draws another card and displays the card (again showing the suit and face value of…
Only correct answer else you get downvote. The races in which three applicants took part have as of late finished. The primary applicant got a votes, the subsequent one got b casts a ballot, the third one got c votes. For every up-and-comer, take care of the accompanying issue: the number of votes ought to be added to this applicant so he wins the political decision (for example the number of decisions in favor of this competitor was completely more prominent than the number of decisions in favor of some other applicant) Kindly note that for every applicant it is important to take care of this issue freely, for example the additional decisions in favor of any applicant don't influence the computations while finding the solution for the other two competitors. Input :The primary line contains one integer t (1≤t≤104) — the number of experiments. Then, at that point, t experiments follow. Each experiment comprises of one line containing three integers a, b, and c (0≤a,b,c≤109). Output…

There are 2016 passengers about to board a plane, numbered 1 through 2016 in that order. Each passenger is assigned to a seat equal to his or her own number. However, the first passenger disregards instructions and instead of sitting in seat number 1, chooses and sits down in a randomly chosen seat. Each subsequent passenger acts according to the following scheme: if their assigned seat is available, they will sit there; otherwise, they will pick at random from the remaining available seats and sit there. What is the probability that the 1512th passenger ends up sitting in their assigned seat? A. 1/2016 B. 1/2 C. 5/8 D. 3/4 E. None of the above

Knight-Knave problems A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. Can you determine who is a knight and who is a knave? a. You meet two inhabitants: Zoey and Mel. Zoey tells you that Mel is a knave. Mel says, Zoey nor I are knaves.' `Neither b. You meet two inhabitants: Bob and Ted. Bob says, `I am a knight or Ted is a knave.' Ted says that only a knave would say that Bob is a knave. Hint: make a propositional variable for each person to indicate if they are a knight and then express their statements as propositions, then write down a truth table and see if you can find a consistent truth assignment.
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. The new scholarly year has begun, and Berland's college has n first-year understudies. They are separated into k scholarly gatherings, in any case, a portion of the gatherings may be vacant. Among the understudies, there are m sets of associates, and every colleague pair may be both in a typical gathering or be in two unique gatherings. Alice is the custodian of the primary years, she needs to have an engaging game to make everybody know one another. To do that, she will choose two unique scholastic gatherings and afterward partition the understudies of those gatherings into two groups. The game requires that there are no colleague sets inside every one of the groups. Alice thinks about the number of sets of gatherings she can choose, with the end goal that it'll be feasible to play a game after that. All understudies of the two chose bunches should participate in the game.…
Correct answer will be upvoted else downvoted. 2k groups take an interest in a season finisher competition. The competition comprises of 2k−1 games. They are held as follows: as a matter of first importance, the groups are parted into sets: group 1 plays against group 2, group 3 plays against group 4 (precisely in a specific order, etc (thus, 2k−1 games are played in that stage). At the point when a group loses a game, it is wiped out, and each game outcomes in disposal of one group (there are no ties). From that point onward, just 2k−1 groups remain. If by some stroke of good luck one group remains, it is pronounced the hero; in any case, 2k−2 games are played: in the first of them, the champ of the game "1 versus 2" plays against the victor of the game "3 versus 4", then, at that point, the victor of the game "5 versus 6" plays against the champ of the game "7 versus 8, etc. This cycle rehashes until just one group remains.
