The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:TFFTFFTTTTFFTFTFTFTTEvery other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:ABC54301 TFTFTFTT TFTFTFFTTFTindicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9. The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points.
Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score, followed by the test grade. Assume the following grade scale:90%–100%, A; 80%–89.99%, B; 70%–79.99%, C; 60%–69.99%, D; and…
your code does not run Exception Handling correctly like shown in my 2nd picture . Can you please fix it ?
fastfoodStats
For this assignment, name your R file fastfoodStats.R
For all questions you should load tidyverse, lm.beta and openintro. You should not need to use any other libraries.
If the openintro package is not installed, you’ll need to do a one-time installation from the Console Window in RStudio like this:install.packages("openintro")
If the lm.beta package is not installed, you’ll need to do a one-time installation from the Console Window in RStudio like this:install.packages("lm.beta")
Load libraries with
suppressPackageStartupMessages(library(tidyverse))suppressPackageStartupMessages(library(lm.beta))
suppressPackageStartupMessages(library(openintro))
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...)
4. Run a regression predicting calories from saturated fat, fiber, and sugar. Based on…

- Using JAVA, Create a File Menu in your GUI Add a file menu to your BulbGUI with options to open any file for reading (and displaying the file as in Project 2), and one to Quit the program. You will need a FileMenuHandler class to handle the events from the FileMenu. Be sure to use getAbsolutePath() when getting the file from the JFileChooser, not getName(). Handle Exceptions Create an exception called IllegalBulbException (by extending IlegalArgumentException as shown in the lecture) and have the constructor of the Bulb throw it. For our purposes, a Bulb is illegal if the wattage is less than 5. Use a try/catch statement to catch this exception in your program, and display the erroneous Bulbs to the console (do not put them in the ArrayList). Use ArrayLists Use an ArrayList to store the unsorted Bulbs. For this project, display only the unsorted bulbs in the GUI.

(You must create some sort of method that can loop through the words to do this, you are not allowed to use Regex Patterns) Hint: This might come in handy String punctuation = "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~"; • You must find the first longest word that appears in the text file with their position retained as well as indicating the number of characters therein, the formatting for this can be seen in Table 1.arrow_forwardnycflights13 For this assignment, you must name your R file nycflights13.R *****use Rmarkdown file in Rstudios For all questions you should load tidyverse and nycflights13.

- in python. Please include docstring, so I can understand each step to this program. Thanks. you will import the json module. Write a class named NeighborhoodPets that has methods for adding a pet, deleting a pet, searching for the owner of a pet, saving data to a JSON file, loading data from a JSON file, and getting a set of all pet species. It will only be loading JSON files that it has previously created, so the internal organization of the data is up to you. The init method takes no parameters and initializes all the data members, which must all be private. The add_pet method takes as parameters the name of the pet, the species of the pet, and the name of the pet's owner. If a pet has the same name as a pet that has already been added, then the function should raise a DuplicateNameError (you'll need to define this exception class).

Hints: you can use cat and egrep.arrow_forwardImplement a simple version of the linux grep command in C++. grep - Looks through a file, line by line, trying to find a user-specified search term in the line. If a line has the word within it, the line is printed out, otherwise it is not. Use the system calls open(), getline(), close(). Requirements (examples run from. terminal) Your program grep is always passed a search term and zero or more files to grep through (thus, more than one is possible). It should go through each line and see if the search term is in it; if so, the line should be printed, and if not, the line should be skipped. [terminal]$ ./grep ! main.cpp main2.cppcout << "Hello, World!";cout << "Programming is great fun!"; The matching is case sensitive. Thus, if searching for world, lines with World will not match. Lines can be arbitrarily long (that is, you may see many many characters before you encounter a newline character, \n). grep should work as expected even with very long lines. For this,…arrow_forward
