python: numpy def purchases(transactions): """ QUESTION 7 - A high-end store is trying to evaluate the total amount that customer's spend per transaction. They want customers to spend anywhere between $130 and $150 on average. - You need to determine whether the average number spent on each transaction per month is above, between, or below the desired amount. - Transactions is a numpy array containing a date, total amount earned each month, and total number of transactions each month. - Above: month's average amount spent per transaction > 150 - Within Range: 150 >= month's average amount spent per transaction >= 130 - Below: month's average amount spent per transaction < 130 - Return a numpy array with "Above", "Within Range" and "Below" for the average amount spent per transaction per month - THIS MUST BE DONE IN ONE LINE HINT: use np.where() and convert the type of each column to float Args: transactions…

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9
