In Python, Given the grades.csv file, where hours = [15,7,8,7.3,19.1,17,14,9.3,4.3,8,12.4,9,6,7.5], and grades = [94,86,87,100,96,94,90,79,88,91,90,86,88,89]. The first column is hours studied and the second column is grades, read its data and place them into two numpy arrays. Find the regression line using the built-in linregress() method. Plot the data points along with the regression line and print: slope, y-intercept, r (correlation coefficient), p-value, standard error. Predict a student’s grade given 10.5 hours of study''' xhours = [ ] yhours = [ ]
I have a text file and I want to read it in C++. variables to use: fname, lname , Id nr, Gender and all third line which is an address The file is : Tommy James 23456731667 Streetname 45 , 154 23 Georgia John Andersson 3456723464 Streetname 12 , 231 32 Las Vegas Kim Larsson 3456312653 Streetnamn 15, 231 56 Florida If we Said the 8th digit in ID number is showing the Gender of the person. By %2== 0 it's Male The output should be: Lname Fname [F] address Is there possible to create a program in C++ with the previously output. lname , fname [F]Adress Without have a problem with Las Vegas word. I have a hard time to figure how I can do the third line in the file. They read to word Las and then the compiler shows terminate called after throwing an instance of ' std::invalid_ argument ' what (): stoi aborted so I figured that the problem I have in one line the city is two word.
Write a program in Python that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: ◦ A: 90 =< x ◦ B: 80 =< x < 90 ◦ C: 70 =< x < 80 ◦ D: 60 =< x < 70 ◦ F: x < 60 • Output the first names, last names, exam scores, and letter grades of the students into a text file named…
Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line.*Note that the contents of the file AcctNumsIn.txt will change when the test is run to test the program against different input.
