Write a Python function called weighted average (), which reads four variables from the keyboard and displays a message with the weighted average. The input variables are: the first note, followed by its weight, and the second note, followed by its weight. The 4 variables given as input are real numbers, and the displayed result is a real number.

Toll roads have different fees at different times of the day and on weekends. Write a function CalcToll() that has three arguments: the current hour of time (int), whether the time is morning (bool), and whether the day is a weekend (bool). The function returns the correct toll fee (double), based on the chart below. Weekday Tolls Before 7:00 am ($1.15) 7:00 am to 9:59 am ($2.95) 10:00 am to 2:59 pm ($1.90) 3:00 pm to 7:59 pm ($3.95) Starting 8:00 pm ($1.40) Weekend Tolls Before 7:00 am ($1.05) 7:00 am to 7:59 pm ($2.15) Starting 8:00 pm ($1.10) Ex: The function calls below, with the given arguments, will return the following toll fees: CalcToll(8, true, false) returns 2.95CalcToll(1, false, false) returns 1.90CalcToll(3, false, true) returns 2.15CalcToll(5, true, true) returns 1.05 need help with code in c++
write a python program 9. You are a class teacher at a kindergarten school. As a task, you asked your students to write a paragraph. Unfortunately, you notice that most of the students did not use capital letters correctly. Your task is to write a function which takes a string as its only parameter and returns a new copy of the string that has been correctly capitalized. Your function should: Capitalize the first letter in the string Capitalize the first letter after a full-stop, exclamation mark or question mark • Capitalize the word “i" if it is in lowercase. Summary: You have to write a function that reads a string from the user and capitalizes. The string is then returned and displayed. Sample Input ('my favourite animal is a dog. a dog has sharp teeth so that it can eat flesh very easily. do you know my pet dog's name? i love my pet very much.') Sample Output My favourite animal is a dog. A dog has sharp teeth so that it can eat flesh very easily. Do you know my pet dog's name? I…
Exercise 5: Write a Python program that inputs five positive integer numbers, sorts them in descending order and finds the median (i.e. middle value). Each must be a distinct number (i.e. all numbers are different). Each number should be input and returned by a function named getValue(.) that receives a prompt message. A second function desSortNumbers(..) should sort numbers and display them on screen in descending order. A third function median(..) should receive five numbers as parameters and returns their median to function main(.) which then prints the median value as shown in figure 5. Please input 5 numbers: 40 20 40 5 97 Invalid input, try again Please input 5 numbers: -40 28 48 90 38 Invalid input, try again Please input 5 numbers: 19 25 7 87 54 Sorted: 7 19 25 54 87 The middle value is 25 Figure 5.

Write in Python Write a function named max that accepts two float values as arguments and returns the value that is the greater of the two. For example, if 7.2 and 12.1 are passed as arguments to the function, the function should return 12.1. Use the function in a program that prompts the user to enter two float values. The program should display the value that is the greater of the two.
3. Write a PYTHON function called midpoint quad.py with signature def midpoint quad (func, a, b, N) #quad = midpoint quad ( func, a, b, N) # comments return quad where func indicates the name of a function, a and b are the lower and upper limits of integration, and N is the number of points, not the number of intervals. Test your midpointquad routine by computing f2rdx = 1. Even if you use only one interval (i.e. N = 2) you should get the exact answer because the midpoint rule integrates linear functions exactly. Use your midpoint routine to estimate the integral of the Runge function, f(x) = 1/(1+x2), over the interval [-5, 5]. The exact answer is 2 arctan (5). Fill in the following table, using scientific notation for the error values so you can see the pattern. Midpoint Result Error N h 11 1.0 101 0.1 1001 0.01 10001 0.001 Estimate the order of accuracy (an integer power of h) by examining the behaviour of the error when h is divided by 10. (In previous problems, we have estimated…

Write a section of Python code (not an entire function) that: Asks the user to input a number between 1 and 10.You do not need to validate the user's input. Displays the message, "This is a low number." if the number is from 1 to 5. Displays the message, "This is a high number." if the number is from 6 to 10. Write the Python code as efficiently as possible.

Use Python to write a function display(num). The value of num is the parameter. If num is even, the function will display the even numbers in the range of 1 to num (both inclusive). If num is odd, the function will display the odd numbers in the range of 1 to num (both inclusive).
