4.16 LAB: Interstate highway numbers Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: I-90 is primary, going east/west. Ex: If the input is: 290 the output is: I-290 is auxiliary, serving I-90, going east/west. Ex: If the input is: 0 the output is: 0 is not a valid interstate highway number. Ex: If the input is: 200 the output is: 200 is not a valid interstate highway number. See Wikipedia for more info on highway numbering. 344614.2153518.qx3zqy7 Use Python. Don't use Java cause that's…
Let l(x) be "x has an internet conection" and C(x, y) be "x and y have chatted over the internet". Assume the domain is all students in a class. Express the following using quantifiers. 1. Jerry does not have an internet connection 2. Exactly one student in the class has an internet connection 3. Someone in your class has an internet connection but has not chatted with anyone else in the class.
Assume you work as a cashier in a restaurant. You must keep track of the amount of money your restaurant earns each day and report it to your boss. If a customer purchases something, that amount is added to the daily income book.Take a customer's order and if a customer enters an "X," the order is complete, and print "Total cost of the items: ". In this way, 3 customers can order at maximum as your restaurant only serves three customers per day; after the service, print the day's total income; if the total money exceeds 500tk, print "Great Work". Otherwise, print "Do Best Next Day."Note: Write a function called “take_order()” that asks users to input food names, calculate the amount and show it to the customer. When the last customer buys, you need to also calculate the total income of the day and show it at the end. Assume that no customers enter invalid food names.The Dictionary ‘price_list’ is set for you and use it in the code for your convenience.price_list={'Juice':30, 'Fried…
Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…
This program deals with processing the results of a survey which was recently conducted. This survey was intended to determine the percentage of students who walk tocampus, the percentage who drive to campus and the percentage who live in residence on campus.The results of the survey are recorded as follows: WDDL... This data is to be interpreted as follows: the first person surveyed said that he walks – hence W isrecorded, the second person said that he drives – hence D, the third person said that he drives –hence D, and the fourth person said that he lives on campus – hence L. Write a C program to which inputs the response for each student and which computes / outputs therequired percentages. Assume that 25 students were surveyed. Your prompt should have the following format: Do you walk, drive or live on campus. UseW – if you walkD – if you driveL – if you live on campusUse the following data for the execution of your program: W D D L L W D D L L W W D D W L W L L D W L W L D

pizza (python)Mario owns a pizzeria. Mario makes all of his pizzas from 10 different ingredients, using 3 ingredients on each pizza. Mario’s cousin Luigi owns a pizzeria as well. Luigi makes all his pizzas from 9 ingredients, using 4 ingredients on each pizza. Mario and Luigi have made a bet: Mario believes that customers can order a larger selection of pizzas in his pizzeria than they can order in Luigi’s pizzeria. Use functions for this assignment. Implement a factorial() function yourself (do not use the one from the math module) When choosing k items from n possible items, the number of possibilities can be obtained using the following formula: (??)=?!?!(?−?)!(nk)=n!k!(n−k)! Make a function called choose with two parameters n and k, that implements the above formula. Write a program that calculates the number of pizzas Mario and Luigi can make. The outcome should look like this: Mario can make 120 pizzas.Luigi can make 126 pizzas. Luigi has won the bet.

Description After midterm, kind teacher C.C. in class Rou decides to holds a bingo game in class Rou. The game rules are as followed: 1. Every student should prepare a 5 by 5 girds on the bingo card. 2. Filling bingo card with a number from 1 to 25. Each number should exist exactly once. 3. Handing the filled bingo card to the teacher. 4. According to teacher CC's mood, she will come out an order of the numbers from 1 to 25. 5. For each bingo card, the teacher will mark the number as the order in step 4. until all numbers in some lines are marked. 6. Each marked number will consider one additional point for the student. There are 12 lines in the bingo card, 5 vertical lines, 5 horizontal lines, and 2 diagonal lines. Please write a program to help teacher C.C. to judge bingo cards. Input The first line of input is an integer nn, shows the number of students, numbering through 1 to n. Followed by 5n5n lines are bingo cards. Every 5 lines are one card.

A c++ code for a shopping mall, The parking garage contains a single lane that holds up to 50vehicles. However, first 10 locations are dedicated to some customers. For the remaining parking places, there is only a single entrance/exit to the garage. If a customer arrives to pick up a vehicle and it is not nearest the exit, all vehicles blocking its path are moved out. The customer’s vehicle is driven out and the other vehicles are restored in the sameorder as they were in original.
