pizzaStats Assignment Description For this assignment, name your R file pizzaStats.R For all questions you should load tidyverse and lm.beta. You should not need to use any other libraries. Load tidyverse with suppressPackageStartupMessages(library(tidyverse)) Load lm.beta withsuppressPackageStartupMessages(library(lm.beta)) Run a regression predicting whether or not wine was ordered from temperature, bill, and pizza. Assign the coefficients of the summary of the model to Q1. The output should look something like this: Estimate Std. Error z value Pr(>|z|)(Intercept) -1.09 1.03 -1.06 0.29temperature -0.04 0.01 -3.20 0.00bill 0.03 0.01 3.75 0.00pizzas 0.19 0.06 3.27 0.00 Here is the link of the pizza.csv https://drive.google.com/file/d/1_m2TjPCkPpMo7Z2Vkp32NiuZrXBxeRn6/view?usp=sharing
Write code for a test class with the following details:1. Create an object of each class mentioned in Question 3, assuming the values for the data members of each class. Create an array that takes the objects of ALL the classes as its elements. Write an enhanced for loop to display the object details. 2. the dealer in Question 4 decides to offer 2% percent discount on the commission at runtime. Write codewith explanation. 3. Add code to the test class that writes the invoice details of Question 6 to a txt document Syntax of the q3 code is given below: import java.util.*; class Car{ //class car String[] name; int reg_number,eng_number, chassis_num,status; String[] city, model, color, date_reg,date_arr,type; float price; float abstract calculate (float price); } class Dealer extends Car{ //inherits from Car String[] deal_name, deal_id, deal_add, deal_pno; float dealer_com ; float abstract calculate (float price) { dealer_com= 0.01*price +…

astfoodStats Assignment Description For this assignment, name your R file fastfoodStats.R For all questions you should load tidyverse, openintro, and lm.beta. You should not need to use any other libraries. suppressPackageStartupMessages(library(tidyverse)) suppressPackageStartupMessages(library(openintro)) suppressPackageStartupMessages(library(lm.beta)) The actual data set is called fastfood. Continue to use %>% for the pipe. CodeGrade does not support the new pipe. Round all float/dbl values to two decimal places. All statistics should be run with variables in the order I state E.g., "Run a regression predicting mileage from mpg, make, and type" would be: lm(mileage ~ mpg + make + type...) To access the fastfood data, run the following: fastfood <- openintro::fastfood Create a correlation matrix for the relations between calories, total_fat, sugar, and calcium for all items at Sonic, Subway, and Taco Bell, omitting missing values with na.omit(). Assign the…
Create a Student class, where attributes associated with each student are name, registration number, father name, degree and department. All attributes should not be accessed directly. One can view the details of all students. Note student attributes can not be changed by any means after initialization.In student class maintaining student count means your program could be able to tell the count of student objects created. (User static counter variable)
Introduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece.…
1. Declare an array to save 4 Dog objects. The Dog class is provided below. Look into the Dog class and find what attributes are needed for a dog object. Then initialize five dogs with the following information: Lily, 5 years old Jacob, 2 years old Sugar, 8 years old Bush, 3 years old 2. Print out every dog using a for loop (use either regular for loop or for-each loop, your choice). But you may find when you print out, the name and age are not displayed. Why? 3. Fix this problem by implementing the toString method in the Dog class. Dog Class: public class Dog { private String name; private int age; public Dog(String name, int age) { this.name = name; this.age = age; } public void setName(String name) { this.name = name; } }
continue from first question, Client class:The client program will allow entry of these data for several different student into an ArrayList and then perform some analysis and queries.Your client class (program) will provide the user with a menu to perform the following operations. You will also need to load the information of the students from a CSV file (student.csv) before displaying the menu. You only need one ArrayList and one menu for this. For the csv file, your first item can be U or G to differentiate whether the entry is creating a UndergraduateStudent object, or a GraduateStudent object. You can then decide how you want other data to be listed in the csv file. You should specify clearly in your documentation the data format of the CSV files used in this assignment.1. Quit (exit the program)2. Add (to the ArrayList) all the marks information about an undergraduate or graduate student by reading it from another CSV file. Your program will ask for the file name.3. Given student…
Q2 Create MusicOrganizer project using BlueJ . (i) Create a MusicOrganizer class and declare an ArrayList for storing the file names of music files into the String object. (ii) Create a constructor for the music organizer class and assign the field to the ArrayList. (iii) Write a method to add a file to the collection. (iv) Write a method to return the number of files in the collection. (v) Write a method to remove a file from the collection. (vi) Make a screen shot of the coding and output.
Objective: This activity has the purpose of helping students to design proper hashing strategies. (Objective 3). Students Instructions: After studying this module, write the answer to the following programming assignments in a text file and submit them as an attached Word doc or PDF through the provided link in Blackboard. The deadline for submitting this assignment is indicated on "Tools", which is located in "Calendar" in the "Blackboard" platform. You will have two (2) attempt to send your answers by Assignment link before the deadline and the last submission would be considered as your final solution. This exercise has Implement a dictionary by using hashing and separate chaining. Question:
True or False? Instantiating an array of objects reserves room to store references only.
