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?

MATLAB. write code for all parts

Exp2: A vectory is given by  X = [−3.5  −5  6.2  11  0  8.1  −9  0  3  −1  3  2.5]   Using conditional statement and loops, develop a program that creates two vectors from X: Vector P contains all positive elements of X Vector N contains the negative elements of X. The elements in new vectors are in the same order as in X. Please show me how to code this on matlab. I have tried watching tutorials on youtube and can not figure out how to code this for the life of me. Thank you.

Complete the function: bool search(vector<int> v, int key). This function searches for value key in vector v and return true if key is found else return false.   In C++

Using the srand() and rand() C++ library, generate a vector of integers.  Prompt the user for the size of the list.  The random integers should be scaled to the range 1 to 100 (see page 283).  Sort the numbers using the sort function from the algorithm library and display the numbers.  Then calculate the percent of numbers from 1 to 50 (including 50) and from 51 to 100.  Report the percentages.

import numpy as np import torch import matplotlib.pyplot as plt Quiz Preparation Question 1. Write a function that generates a random tensor of n x n (n is the input). The output is the mean of the tensor. = 2, 4, 8, 16, ... 1024 and generate a vector 2. Write a code (for loop) that call that calls the function above with n = M(n). Plot the vector as a function of the log of n. 3. Given an n x m array write a code that replaces every element that is larger than 0.5 with 0.5. 4. The second derivative of a function can be approximated by the finite difference 1 ƒ"(x₂) = 73 (ƒ(£;+1) — 2ƒ(x;) + f(x;-1)) Given a vector f with values f = [f(xo),..., f(n) write a code that computes the approximation to f"(x) 5. The power method is a method to compute the largest eigenvalue of a matrix. Your google search is using this method every time you perform a google search. The method consists of the iteration Vj+1 = Av; || Avi|| where v; is a vector with chosen as a random vector, and A is the matrix…
