3. HSBC sends the monthly transaction report to all its customers through email. When the customer opens the file send by the bank, the customer is required to enter a valid customer ID Number. The ID Number is a six character long ending with 2 uppercase letters. Examples of valid customer ID Numbers: 5678XY 2343 WA 8987HL Write a Pseudocode that will: 1) Ask the customer to enter a valid ID Number 2) if customer input is "E", allow the customer to quit the program 3) if the ID Number is too short, then tell the customer to renter 4) if the last two characters do not follow the rules, then tell the customer allow the customer to keep entering customer ID Number.

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.

Q1 Which of the following statements is true if x (a character array) is added (+) to a y (2 x 2 double)? Select one: a. Variable x will be converted into a double and then concatenated with y to create new ASCII-type variable b. The addition operation (+) cannot be performed c. Variable y will be converted into a string and then concatenated with x to create a new string-type variable d. ASCII values of x are added to y to create a new double-type variable e. It is equivalent to the statement x == y and creates a logical-type variable Q2 Consider the following non-linear equation where x is the independent variable, y is the dependent variable, and A and B are constants. Which of the following is the resulting gradient variable in linearised form? Select one: a. B b. log10(B) c. log(-A) d. A e. exp(B) Q3 Which of the following statements is false for the function header below? function [cat, ox, dragon] = rat(pig, snake) Select one:…
Code in Python: 10 users were asked to select from four options (A, B, C and D). Their responses are stored in the variable x below. x = pd.Series(["A" , "B", "A", "A", "D", "C", "A", "C", "A", "A"]) Use the data in x to plot a pie chart representing the counts for each of the 4 options. This can be done by: - Counting the number of occurrences of each option and storing it into a DataFrame. - Invoking the plot method in Pandas with pie option on the DataFrame, indicating that your y value is the counts column.
09.coded in it When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}') Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65..

Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…
