2. Write R code that will create a function named logistic. This will be a function of three arguments k, x0 andL. The function should return a function with a single argument x that computesL.f(z) =1+e-(z-zo)"Use your function to create a function named logistic.standard that computes 1/(1+e) and demonstratethat the function works when x = 0 and t = 10.

logistic regression is used to predict the probability of a certain class or event.

You should not import anything from an external library in the work , The math module has a function, factorial
Write a function(define) the_divisor(n, bound), that takes in two int values. N is the number you search for a divisor and bound will also be an integer. The function the_divisor should return the smallest divisor which is greater than bound. If no such integers exists, return -1. You cannot assume that the first argument will be larger than the second. In python >>> the_divisor(25,3) 5 >>>the_divisor(5,25) -1
Write a programmer defined function that calculates the surface area of right circular cone(see the below figure) using the following formula: A = tr(r + /h² + r2) Where, r is the radius and h is the height of the right circular cone. Give your function a suitable name and parameter list. Test your function by writing at least one function call with any appropriate values. Write the code at the space provided below. Optionally, upload your Python file at link below.
In Python: Write a function called pizza_cost that returns the cost per square inch of a circular pizza given its diameter in inches and price. The area of a circle is a r e a = π r 2 Hint: Use 3.14159 for the value of π Write a main() function in your file to exercise your function to show that it works correctly. Your test implementation should not rely on visual inspection to determine if the tests pass.

Write a function count_evens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2). Ex: If the four parameters are: 1 22 11 40 then the returned count will be: 2 Hint: Use the modulo operator % to determine if each number is even or odd. Your program must define the function:count_evens(num1, num2, num3, num4) python # Define your function here if __name__ == '__main__': num1 = int(input()) num2 = int(input()) num3 = int(input()) num4 = int(input()) result = count_evens(num1, num2, num3, num4) print('Total evens:', result)
Python: we usually refer to two floating point numbers as being equal when they are close enough in value for our purposes. Write a function named almost_equal that receives two floating point numbers and returns whether they are close enough to each other. Two floating points numbers are close enough to each other if they are within one-tenth of 1% (0.001). Write a main() function in your file to exercise your function to show that it works correctly. Your test implementation should not rely on visual inspection to determine if the tests pass. Hint: The fabs function in the math module of Python's libraries returns the absolute value of its parameter.
Write a programmer defined function that calculates the volume of circular cone(see the below figure) using the following formula: volume t r² h Where, r is the radius and h is the height of the right circular cone. Give your function a suitable name and parameter list. Test your function by writing at least one function call with any appropriate values. Write the code at the space provided below. Optionally, upload your Python file at link below.
First write a function f to generate and return a random number between 0 to 100 In the main function, you keep calling function f until the returned value is less than 10 Then you should print out how many times the function f has been called. Note that every time f will only return a single random number, and the declaration of f is as follows: int f() For instance, if f returns 23, 89, 10, 1, then your program should print 4 on the screen. C++ language Hint 1. You can implement the function using different methods, like the static variable Hint 2. You can use the modular operator to shrink the generated random value, i.e., random() % 101 will guarantee the result is between 0 and 100.
In Matlab and octave, "rand" built in function gives a random number between 0 and 1. "Type rand and see that a number is returned between 0 and 1". Using the rand function write a script that. Write a script that generates random numbers between 0 and 10 using the rand function. The script must also tells the user if the produced random number is bigger than 5 or equal or less than 5. Such as: X>5 "The number is bigger than 5" X
How would I do this in Jupyter? Write a function that takes 3 numbers as input and returns the maximum amongst the 3 numbers as the output. e.g.: func_max(5, 10, 30) Maximum is 30
Write a function averageDigits that computes the average of the digits of a 3-digit positive number in the range [100,999), Use the following function prototype: double averageDigits(int); For example, averageDigits(936) returns 6.0 ((9+3+6)/3). Write a test program that prompts the user to enter a 3-digit number, call the function averageDigits and print the result in the main program. The process is repeated if the user enters y to continue.
