Create a NumPy array which represents the values of the function f(x, y) = x^2 − y^2 with x ∈ [−1, 1] and y ∈ [−2, 2]. Make a contourf plot of this function .

Suppoce we're given numpy arrays of names and scores, where each row in the scores array lists the midterm and final scores for that respective student. For example, Carol has a 75 on the midterm and 99 on the final. names = np. array([ "Alice" "Bob". "Carol","Derek ","Erin"]) Scores = np.array([ [95, 98], [82, 88], [75, 99], [80, 90], 85, 82 ]]) Write function avgMidtermNoC that takes ve parameters names and score arrays, and returns the average score on the midterm, exduding anyone who's name starta with C.

Background: This assignment will help you further learn to use multidimensional arrays. You will need a 10x2 matrix for this problem. Consider 10 points on a map, You need to identify the distance between each point (or vertex). A vertex requires two pieces of information. An x,y coordinate (think longitude and latitude.) This is why you have a matrix of 10x2, each entry is the two values you will need. You can think of these points a cities, or friend's houses. We're only looking for a direct route (as the crow flies) not taking roads to make it simpler. You can find the distance between any two points by use of: sqr_root((x1 - x2)^2 + (y1 - y2)^2) You will need to fill your matrix with some random values. Then you will need to calculate the distance between each possible point, eventually displaying it on a matrix in output. Think something like: 1 2 3 4 5 1 0 8 12 4 6 2 8 0 7 .... 3 12 7 .... 4 4 ... 5 6 ... Hint:...

Let x and y be two numpy arrays with x.shape = (6, 4, 3, 2) and y.shape = (3, 2). What is the shape of numpy.maximum(x, y)?

Given an array with 200 rows and 800 columns. Thearray already contains data. Write the code required in C tooutput the sum of all the elements in the last 50 rows.

An array is positive dominant if it contains strictly more unique positive values than unique negative values. Write a function that returns true if an array is positive dominant. Examples ispositiveDominant([1, 1, 1, 1, -3, -4]) // There is only 1 unique positive value (1). // There are 2 unique negative values (-3, -4). ispositiveDominant([5, 99, 832, -3, -4]) → true ispositiveDominant([5, 0]) → true ispositive Dominant([0, -4, -1]) → false

TASK 1. Re-write this code using Lambda. S TASK 2. Create an array2 that consists of 30987888 digits. Write a code using Lambda function to display only even numbers from array2. int[] array = { 2, 6, 4, 12, 7, 8, 9, 13, 2 }; var orderedFilteredArray = from element in array where element < 7 orderby element select element; PrintArray(orderedFilteredArray, "All values less than 7 and sorted:");
