The program, has the following features: • Option to perform differentiation or integration N value data will be ask or inputted The program will display the data inputted in tabulated form • Will perform the following for differentiation base on the user selection o 1 derivative using 2-pt forward; 2-point backward and 2- pt central difference o 2nd derivative using 3- pt forward; 3-point backward and 3-pt central difference • For Numerical integration base on the user selection o Multiple application of trapezoidal rule for an n-segment o Simpson 1/3 rule for an n-segment o Simpson 3/8 rule for an n-segment

Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…
SAME PARAMETERS: In the RENTALS table shown in fig 2, 40 customers have created 50 rental contracts over time. A RENTALS record is 122 bytes and the block size for your OS is set to 1024 bytes with each block having a 1 byte pointer to the next written block as well as a 1 byte pointer to the next physically consecutive block. Assuming spanned organization, how many blocks do you estimate the RENTALS file is using at its current size? multiple choice a.50 b.6 c.400 d.7

This part of the quiz will contain 4 parts. A function called grade, a function called pgrade, a prototype file called grade.h and a main function. In this part you will create the main function which will do the following: main This main function will use the functions grade and pgrade to produce the grades for the following students and display the appropriate grade with the appropriate message. The semester grade will be based on the fact that the quiz average is 25% of the grade, the final is 20% of the grade, assignments is 20% of the grade and programs are 35% of the grade. The student grades are as follows: Student Name Assignments Programs Quiz Ave Final Tom 63 Francis Maria Jan 75 90 95 85 sample of output Harry Grade B Good 85 75 95 90 93 92 71 69 87 91 73 A
The file london_weather.csv contains weather data for the years 1979 to 2020. The first five lines of this file are: date,cloud_cover,sunshine,global_radiation,max_temp,mean_temp,min_temp,precipitation,pressure,snow_depth19790101,2,7,52,2.3,-4.1,-7.5,0.4,101900,919790102,6,1.7,27,1.6,-2.6,-7.5,0,102530,819790103,5,0,13,1.3,-2.8,-7.2,0,102050,419790104,8,0,13,-0.3,-2.6,-6.5,0,100840,2 Note, in particular, that the dates are given as eight-digit integers in the format YYYYMMDD. There appears to be some inconsistencies in this data, as there are rows for which the column max_temp contains an entry that is smaller than the corresponding entry in min_temp. Write a Python function wrong_temperature(year) that returns the number of days in a given year for which the column max_temp contains an entry that is smaller than the corresponding entry in the column min_temp.
I need to merge three datasets so that I can create a custom function that would do the following: Create a function called theme_by_year that takes as input a year (as an integer) and shows the theme ids and theme names (listed in order by theme id) that were in sets that year. The column names must be id and name_themes (to differentiate between the name of a theme and the name of a set) in that order. The index should be reset and go from 0 to n-1. Each theme should only be listed once even if it appeared in more than one set from that year -- duplicate themes should be based on theme id and not name since there are some themes with the same name but with a different id. Hint: It will help if you were to think about merging appropriate DataFrames to help you get this answer. The desired output should look like this: theme_by_year(1960) Output: id name_themes0 371 Supplemental1 497 Books2 513 Classic Here's what I tried, but I did not get the desired output:

calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100
c# Create a small Sports database with two tables: Team and Athlete. The Team table should include fields for the type of team (e.g., basketball), coach's name (both last and first), and the season the sport is most active (S for spring, F for Fall, or B for both). The Athlete table should include fields for student number, student first and last names, and type of sport. Use the same identifier for type of sport in both tables to enable the tables to be related and linked. Populate the tables with sporting teams from your school. Write a C# program that displays information about each team, including the names of the athletes. The data base we have provided to us just need to know how to program it in with the other guidelines given.
For this week's assignment you will allow the user to add employee, view all employees, search employee by ssn, and edit employee information. Below this is what its supposed to look like when completed. I have also included what I started to do but I can't figure out how to add the search by SSN option or the edit employee option. If you can give me a step by step on how to do this in python I would greatly appreciate it.
Code should be in Python Prompt the user for a title for data. Output the title.Ex: Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored Prompt the user for the headers of two columns of a table. Output the column headers.Ex: Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers.Ex: Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6 Perform error checking for the data point entries.
