Using broadcasting, create a 10 by 10 numpy array where each row is [1.,2.,3.,4.,5.,1.,2.,3.,4.,5.]. Then multiply, with a single statement, the third and fourth rows by 3. Then, again with a single statement, subtract 15 from the ninth and tenth columns.

2. Use a two-dimensional (double-subscripted) array to solve the following problem: A company has four salespeople who sell five different products. Let each salesperson represent a row of your array and each product a column. You now have a 4 x 5 array. Once a day, each salesperson submits a slip for each different type of product he or she sold. Each slip contains: The salesperson’s number (1 to 4) (use this to get row subscript) The product number (1 to 5) (use this to get column subscript) The total dollar value of that product sold that day Thus, each salesperson submits from 0 to 5 sales slips per day (0, if they made no sales that day; and 5, if they sold every product that day). Your program will read a file that contains the information from all of the sales slips for the last month. Read until EOF. The file is named "productSales.txt". You need to create this file with at least 10 entries. Remember that the first number is the salesperson, the second number is the product,…

Create a 2-D array as shown in exampleArray. Then, delete the second column from the given array and insert the newColumn given below in its place. exampleArray = [34,43,73] [82,22,12] [53,94,66] newColumn = [10,10,10] Then plot the new 2D array.
