The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, ex: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() function, which has an index n as parameter and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: fibonacci (7) is 13 Note: Use a for loop and DO NOT use recursion. 461710.3116374.qx3zqy7 LAB ACTIVITY 1 def fibonacci(n): 1234567 4 7.34.1: LAB: Fibonacci sequence 6 #Type your code here. 5 if __name__ start_num = '__main__': int(input()) main.py print(f'fibonacci ({start_num}) is {fibonacci (start_num)}') 0/10 Load default template...
A student writes several functions to swap the values of the two variables x and y, i.e. if x=1 and y=2, after calling the swap function x=2 and y=1. The different functions that the student writes are given below: def swap1(x,y) : x=y y=x return(x,y) def swap2(x,y) : return(y,x) def swap3(x,y) : z=x x=y y=z return(x,y) def swap4(x,y) : x,y=y,x return(x,y) Which of the functions swap1, swap2, swap3, and swap4 is correct? Functions swap3, and swap4 only Functions swap2, swap3, and swap4 only Function swap1 only Functions swap1, swap2, and swap3 only

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 output: 1712 is a leap year. input: 1913 output: 1913 is not a leap year. Your program must define and call the following function. The function should return true if the input year is a leap year and false otherwise.def is_leap_year(user_year) My Code: def is_leap_year(user_year):if((user_year % 4 == 0 and user_year % 100 != 0) or (user_year % 400 == 0)):print("{} is a leap…

Consider the following function, and then indicate which of the summations below accurately represent the value returned by this function. Note: There might be more than one summation that is correct. Select all that apply. You might want to write down the correct summation on your own, then figure out which of the options below are equal to that summation. int summation_party(int n) int i, x = e; for (i = 1; i « n; i++) x += 5 + i; return x; Your options are: a) i=1 b) (5+i) c) i=1 n-1 d) (5+i) i=1 n-1 e) 5. 1=1 f) 5+ Σ 1=1 1=1

Compute and Plot the ROC Curve Write a function from scratch called roc_curve_computer that accepts (in this exact order): a list of true labels a list of prediction probabilities (notice these are probabilities and not predictions - you will need to obtain the predictions from these probabilities) a list of threshold values. The function must compute and return the True Positive Rate (TPR, also called recall) and the False Positive Rate (FPR) for each threshold value in the threshold value list that is passed to the function. Important: Be sure to reuse functions and code segments from your work above! You should reuse two of your above created functions so that you do not duplicate your code. The function you will write behaves identically to Scikit-Learn's roc_curve function, except that it will take the list of thresholds in as input rather than return them as output. Your function must calculate one value of TPR and one value of FPR for each of the threshold values in the list.…
