Write a function future-date which takes four integer parameters: year, month, day and num-days. It will return the future date in num-days days. For example, (future-date 2015 2 3 29) returns (list 2015 3 4) meaning 29 days from Feb 3, 2015 will be Mar 4, 2015. Note that you do need to consider leap years (divisible by 4 but not by 100 unless it's divisible by 400). You may need an auxiliary function to decide the number of days each month has.
In C++, m%n is the remainder when the integer m is divided by the integer n. We can define a function to test whether an integer is even as follows: bool even(int k) { if ( k % 2 == 1 ) return false; else return true;} Translate this function into a standard mathematical function specification.
Part (a) Write a python function that computes the binomial coefficient ("). The function should return the correct answer for any positive integer n and k where k=m pass Part (c) Suppose that the number of people in the trial is 100. Then: • Plot a curve that shows how the probability of type 1 error changes with the choice of m, for m = 1,...n assuming that the null hypothesis holds (in red), • On the same picture, plot the probability of type 2 error vs the value of m in the case in which the new drug is effective with proability 0.68 (in blue). You can plot the two curves using matplotlib.pyplot. You can select the color by passing color='r' or color='b' to the plt.plot() function. [4]: n - 100 # your code here def plot_curve (): pass [5]: plot_curve() Part (d) Based on the picture above, what value of m do you think would be suitable to keep both type 1 and type 2 error small at the same time? (You may assume that the company claims the new drug has 68% accuracy) [6]: # your…

= Write a function ApproxSolver1(a0, a1, b0, b1, m) that takes as input two entries a0, a1 representing the second order dif- ference equation a0xn + α₁xn+1 + Xn+2 0, and two more b0, b1 representing initial conditions (x0,x1) = (bo, b₁), along with a value m, and outputs an integer which is an approximate value of xm by (assuming distinct roots of the auxiliary equation).
-Python- Write a function get_letter_grade, such that when given * a lab grade score and * a list of the grade cutoffsreturns the letter grade of that score.Note: Your function automatically returns A for the values that are >= to the first cutoff-value in the list, then A- for the second cutoff-value, B+ for the third and so on. The function returns None for anything that's below the score for B-. You test that get_letter_grade(97, [93, 90, 87, 83, 80]) correctly returns an A, and get_letter_grade(93, [97, 90, 87, 83, 80]) returns A-. DO NOT hard-code the cutoffs, since they can change! You can copy/paste the following template: def get_letter_grade(score, cutoffs): if score ... : return 'A' ...: return 'A-' ...: return 'B+' ...: return 'B' ...: return 'B-'
Write a program that will:• Select a random number between 1 and 100.• Test if the number is prime• Call a function named isPrime(). Pass the number to be tested. isPrime() should test whetherthe number has any factors other than 1 and itself. isPrime() returns either True or False.• isPrime() should use a function isDivisible(x,y) to test if y divides evenly into x. That is,isDivisible() will identify whether y is a factor of x.• Print the result
For each of the following expressions, write functions f1, f2, f3, and f4 such that the evaluation of each expression succeeds, without causing an error. Be sure to use lambdas in your function definition instead of nested def statements. Each function should have a one line solution. f1 takes in nothing and returns 3. f2 takes in nothing and returns a function that takes in nothing and returns 3. f3 takes in nothing and returns a function that takes in 1 value and returns that same value. f4 takes in nothing and returns a function. This function takes in nothing and returns another function. This next function takes in a value and returns yet another function. This final function takes in nothing and returns the value passed into the previous function (if this explanation is confusing, have a look at the doctest, and it might be more clear). def f1(): >>> f1() 3 |||||| "*** YOUR CODE HERE ***" def f2(): |||||| >>> f2() () 3 |||||| "*** YOUR CODE HERE ***" def f3(): |||||| >>> f3() (3)…
Write a function sumOddInts(). sumOddInts should return the sum of all odd integers between the values provided to the two parameters, inclusive, e.g., sumOddInts(5,9) should return 21. start and finish do not have to be odd, e.g, sumOddInts (4,8) should return 12. start and finish do not have to be positive, e.g., sumoddlnts(-5,7) should return 7, However, finish may be assumed to be greater or equal to start. whereas Python has a modulo operator "%", MATLAB has a built-in mod() function that returns the remainder. For instance, >> mod (13,5) ans = 3 >> mod (13,2) ans = 1 Notes: End all assignment statements with a semi-colon to suppress output to screen. Include the key word end at the end of your function.
Redesign the solution using functions. For this lab: 1. You will define a function named main() (LO 1) 2. You will get input in the main function and pass it to the following functions: (LO 2) a. milesToKm() b. FahToCel() c. GalToLit() d. PoundsToKg() e. InchesToCm() 3. Each function will require that you have a local variable to store the result of the calculation. This result will then be displayed using the print statement from within the function
Exercise 5 The greatest common divisor (GCD) of a and b is the largest number that divides both of them with no remainder. One way to find the GCD of two numbers is based on the observation that if r is the remainder when a is divided by b, then gcd(a, b) = gcd(b, r). As a base case, we can use gcd(a, 0) = a. Write a function called gcd that takes parameters a and b and returns their greatest common divisor.
Using informal arguments: Write a function polynomial which implements a polynomial function of arbitrary integer order ?: ?(?)=?0+?1?+?2?2+⋯+???? The function should take ? as a formal argument and the constants {??} as informal arguments. You will have to use the *args function argument. The enumerate builtin function will also be convenient in order to get the power ? to go along with each ??. Recall, you can index tuples just like arrays by using [ ]. Test your function by plotting: ?(?)=1+2?2 over the range (-3,3).
