***in python only*** use turtle function Define the concentricCircles function such that: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the largest (i.e., outermost) circle, and then every other circle out to the edge alternates between that color and the 'other' color. The difference between the radii of subsequent circles is always the same, and this difference is also equal to the radius of the smallest circle. Put another way: the distance between the inside and outside of each ring is the same.

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…
Fix an error and show it please? And here are the information about the homework and for the error too. def kwargs_to_args_decorator(*args, **kwargs): This question is meant to test your knowledge of creating a decorator that accepts an arbitrary number of positional and keyword arguments, to decorate a function that accepts an arbitrary number of positional and keyword arguments, and alters the arguments before passing them to the decorated function. When the decorated function is invoked, this decorator should modify the arguments the decorated function receives. This decorator should filter out all positional arguments passed to the decorated function, which are found in the positional arguments passed to the decorator when the decorator was initialized. It should also filter out all keyword arguments with keys that are found in the keyword arguments given to the decorator when the decorator was initialized. After performing the modifications to the arguments, the decorator should…
Define an enumeration type, triangleType, that has the values scalene, isosceles, equilateraland noTriangle. Write a function triangleShape that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note, ina triangle, the sum of the lengths of any two sides is greater than the length of the third side). Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle. The user can enter the sides in no particular order. C++
Please answer it in Python Write a palindrome function that takes a word as an argument and returns a Boolean indicating whether the word is a palindrome. A palindrome is a word that remains the same when read from right to left instead of the usual order from left to right. Example: palindrome('here') is True but palindrome('go') is False. Write a function word_allows taking as an argument a word and a list of forbidden words, and returning True if the word is allowed, and False if the word is prohibited. Example: word_allows('fric', ['sous', 'fric', 'thune', 'ble']) is False word_allows('silver', ['sous', 'fric', 'thune', 'ble']) is true
Create a program that accepts an integer N, and pass it to the function generatePattern. generatePattern() function which has the following description: Return type - void Parameter - integer n This function prints a right triangular pattern of letter 'T' based on the value of n. The top of the triangle starts with 1 and increments by one down on the next line until the integer n. For each row of in printing the right triangle, print "T" for n times. In the main function, call the generatePattern() function. Input 1. One line containing an integer Output Enter N: 4 T TT TTT TTTT
function [P, A] = rect(L, W) P= 2 (L+ W); A =L*W; end Above function is defined to find perimeter and area of a rectangle. If a rectangle has length 10 mm and width 7 mm then the correct way to get perimeter and area of a given rectangle by executing this function is Select one: a. [A, B] = rect(10, 7) b. rect(7, 10) c. [A, B] = rect(7, 10) d. rect(10, 7)
b. Drawing a polygon Now that you can draw a circle, the next step is to draw a polygon inside the circle. Write a function DrawPolygon (N). The points of a N-sided polygon should be at angles 2π/N. You should add an extra point at the end so your polygon looks closed. Use your function to draw a 5-sided polygon (after drawing the circle): DrawCircle() DrawPolygon (5) plt.show() Write below your function to draw a N sided polygon and then use it to draw a 5-sided polygon. You can use dTheta = 2*np.pi/N in your function. ? Answer (start) # ANSWER ME Answer (end)

Python only* Use recursive function*. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters here is the specification for concentricCircles function: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. When viewed as nested rings, all rings should have the same thickness. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the outermost circle, and then every other circle in to the center alternates between that color and the other color. We will test both how many circles are drawn as well as whether the correct circles are drawn in the correct order. Hint: Each function call frame only needs to draw a single circle. Note that you must use the turtleBeads drawDot function to draw each circle Do not use any kind of loop Within the definition of…
Write a recursive function called draw_triangle() that outputs lines of '*' to form a right side up isosceles triangle. Function draw_triangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting. Hint: The number of '*' increases by 2 for every line drawn. Ex: If the input of the program is: 3 the function draw_triangle() outputs: * *** Ex: If the input of the program is: 19 the function draw_triangle() outputs: * *** ***** ******* ********* *********** ************* *************** ***************** ******************* Note: No space is output before the first '*' on the last line when the base length is 19. if __name__ == '__main__': base_length = int(input()) draw_triangle(base_length)
