The file week12.py contains a matrix-valued function, f.  More specifically, given any float x, the value f(x) returned by this function is a square Numpy array. There exists exactly one value x in the interval (-10,10) for which the matrix f(x) is singular.  Print this value correct to exactly 10 decimal places.

Question : Imagine that you track your commute times for (10 days) and recorded your observations in minutes as {17, 16, 20, 24, 22, 15, 21, 15, 17, 22}. Enter your observations into a series (vector) in Python and label it 'data'. Next answer the following questions: ● How many times were your commute 20 minutes or more? Hint: Write a condition! What percent of your commutes are less than 17 minutes?

vector, or a matrix in the same way as described for rand function. EXERCISE I8 Generate a random integer between I and 10. Ask user to guess the number. If user's guess is incorrect, ask' to guess again until user gets it right. At this point, tell user that he guessed it correctly and print out the number of attempts it took for the correct guess. Output Samples >> exercisel8 Please guess an integer between 1 and 10: 5 Your guess is incorrect. Please try again: 2 You guessed it correctly in 2 attemptS >> >> exercise16 Please guess an integer between 1 and 10: 2 Your guess is incorrect. Please try again: 3 Your guess is incorrect. Please try again: 6 Your guess is incorrect. Please try again: 5 Your guess is incorrect. Please try again: 8 Your guess is incorrect. Please try again: 9 Your guess is incorrect. Please try again: 10 Your guess is incorrect. Please try again: 1 Your guess is incorrect. Please try again: 4 Your guess is incorrect. Please try again: 7 You guessed it correctly…

Write a function to find the maximum sum of a subarray within a given array of integers. The subarray should be contiguous, meaning the elements are adjacent to each other in the array. For example, given the array [-2, 1, -3, 4, -1, 2, 1, -5, 4], the maximum sum of a subarray is 6, which corresponds to the subarray [4, -1, 2, 1]. Write a function named `maxSubarraySum` that takes an array of integers as input and returns the maximum sum of a subarray. Note: If all the elements in the array are negative, the function should return O. Example: Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4] Output: 6 Input: [-1, -2, -3, -4] Output: 0 Write the 'maxSubarraySum` function that solves this problem efficiently.

Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1,2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver.
