In python Download the hw08files.zip folder from Canvas, andextract the files. Create your hw08.py file in the samedirectory as the extracted files: all of the test cases for thisassignment will assume that your Python file is in thesame folder as the sample files.Open up the covid_data.csv file provided and browsethe data. This CSV file was obtained from the CDCwebsite:https://data.cdc.gov/Case-Surveillance/United-States-COVID-19-Cases-and-Deaths-by-State-o/9mfq-cb36. Itcontains data reported by each state about the number ofCOVID-19 cases in the state on various dates.The columns you'll need to use in this problem are asfollows:•First column: submission date - this columncontains the date each data point was submittedSecond column: state - this column contains a(usually) two letter abbreviation for the statesubmitting the data.Sixth column: new case - this column containsthe number of new COVID-19 cases detectedsince the last report from that state. Write a function new_cases (date, state) that takesin two strings representing a date and a two-letter stateabbreviation, and returns an integer representing thenumber of new cases reported by the given state on thatdate. If there is no row in the file with the givenstate/date combination, the function should instead return-1.You may assume that the covid_data.csv file willexist within the same folder as hw08.py, and will beformatted in the same manner as the one given to you.You are permitted to import the csv module, but this isnot required.Examples:>>> new_cases('08/08/2020', 'MN')797>>> new_cases ('11/21/2021', 'NE')0>>> new_cases('01/05/2022', 'IA')4268>>> new_cases('02/09/2023', 'MO')-1>>> new_cases ('10/22/2020', 'QQ')-1

Write queries that provide the information asked by each question. Your queries should extract the answers directly. If you need additional step (e.g., hand counting the number of rows) to get the answer after running a query, the query is not considered as the right query for the question. Copy and paste your queries and result table to a Word file and upload it on Canvas. There are two csv files: visit.csv and patient.csv. Below is the description of the data in each File. The visit.csv contains data for 17,580 emergency room (ER) visits: Column Name Description ID for each unique visit. ID for each unique patient. Reason for each ER visit. The values include: 'Pain back’, 'Difficulty Breathing', etc. Urgency of the visit reason. The values include: 'Lowest', 'Low', 'Medium', 'High’, 'Highest’, 'Unknown’. How a patient is transported to the emergency room. The values include: Private Vehicle, EMS Ground, EMS Air, Walk, Public Trans, Police/Jail. Whether a patient is admitted to…

Create an Eclipse Java project that reads in the names and postal (Zip) code data for individuals from the attached "employee-2.txt Download employee-2.txt" file (note: you need to add the text file with the exact file name to the root "project folder" of your Eclipse Java project, not the "src" folder). In the attached text file, edit the last row manually to add your own First Name, Last Name and Zip code. Your project should read in the employee data provided in the text file and store the data into a LinkedList<Employee> data structure, for which, you need to write a Java class named "Employee.java" that defines a first name (type String), a last name (type String), a postal code (type int or String), an Employee "constructor" and a toString() method. You may optionally define "setters" and "getters" methods in the "Employee.java" class. You should write a separate driver class named "EmployeeListDriver.java" to implement the main() method, the main() method is where you…
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…

Please write this small R code: In the setup chunk,, add code to load the following 3 packages: tidyverse, plotly, and crosstalk. Recall that packages are loaded with the library function, e.g. Below these, add another line of code to read in the data from the pokemon.csv file using the read_csvfunction, and store it as a variable called pokemon. You should do this in setup chunk at the top of the Rmd file. (You can leave the columns as their default datatypes.) Make sure you use read_csv and not read.csv (read_csv is a more modern function that is part of the tidyverse).

Need help with this. I attached how it should look Declare the questionList variable, storing in it the node list created by the querySelectorAll() method using “div#quiz input” as the CSS selector. Add an onclickevent handler to the startQuiz object, running an anonymous function that sets the class attribute of the overlay object to “showquiz” and repeats the countdown() function every 1 second (every 1000 milliseconds), storing the id of the timed command in the global timeID variable you declared in Step 3. Create the countdown()function to update the quiz clock. Within the function create an if else statement that tests whether the value of the timeLeft variable is equal to 0. If it is equal to 0, do the following: 0. Use the clearInterval()method to cancel the timed command with the variable timeID. Declare a…
Go to your main.py file. On the first line, add a docstring explaining what your file does. Then, assign a variable called whole_num to the user’s input and cast it to an integer. Next, print 10 underscores as the top border of the table. On the first line print your whole number, then multiply your whole number by multiples of 2's till 10 and print that out. Finally, print 10 underscores again for the bottom border of the table, as in step 3. Run the file by using the python3 main.py command.
