Squared error (SE) is the difference between a predicted value and actual value squared, i.e., (p- a)?. In Excel, predicted values have been entered in A1:A20. The corresponding actual values have been entered in B1:B20. I want the SE shown in cells C1:C20 using a single multicell dynamic array formula in cell C1. Which of the following formulas for cell C1 accomplishes this? Select one: O a. =A1-B1^2, copied to cells C1 through C20 O b. = (A1:A20 – B1:B20)^2 O c. =(Sum(A1:A20)-Sum(B1:B20))^2 O d. = (A1 – B1:A20 - B20)^2

Assume a store purchases products from vendors and stores in the warehouse. There is a system that will facilitate to enter data of products which are going to be stored in the warehouse. Then these products are moved to the store for sale. The products moved from warehouse to store in reverse order as entered in the warehouse. i.e. The products entered first in the warehouse will be removed at the end. You have to implement the system using an array. Your system will facilitate to enter data of product when we have to store product in the warehouse and remove data of product when we have to move it from warehouse to store. Data for product is; productId, productTitle, and productPrice.
B. The following triangle strip Sı={0, 1, 2, 3, 7, 1, 5, 4, 7, 6, 2, 4, 0, 1} is decoded as a set of 12 triangles: {012, 123, 237, 371, 715, 154, 547, 476, 762, 624, 240, 401}, which are supposed to represent a cube as shown in the figure below, but there is a problem. 1. What is the problem? 2. Fix the problem by replacing the set of 12 triangles above with a different set that make the surface correctly oriented. AV 6. 2, 3 5
Using python and sys.argv Create a program called randdf.py that has a function that takes two integer arguments and prints a Pandas dataframe. The two arguments will correspond to the number of rows and number of columns, respectively. The dataframe should be filled with random integers from 0 to 100. Set your random seed to 56. Note: Use random from numpy. Otherwise, you might get a different result.
Write a C program that Defines a two-dimensional array of 7 rows and 7 columns Promotes the user to fill the array with integes. Tests whether a two-dimensional array has four consecutive numbers of the same value, either horizontally, vertically, or diagonally, and displays "Pattern Found" if the array contains four consecutive numbers with the same value. Otherwise, display Pattern NOT Found. Here are some examples of the Pattern Found case 0 103161 016 86 0 1 0 10316 1 0103161 0 103161 0168601 01686 01 016 86 0 1 5621 29 5521829 5621629 9621 829 6 5 6119 1 6 5 6119 1 6 56 61 9 1 6 96119 1 1361 4 07 1561 4 0 7 1361 4 07 13914 07 33334 07 3533 4 07 36334 07 3339407
The manager of the team comes over to you and tells you he needs a simple process in place to sort through the raw lap times which is currently just a list of numbers (in seconds) in an array: lap_times = [76.43, 77.92, 74.35, 80.12, 75.10, 76.43, 76.01, 75.35] You need to design an algorithm (you can use a programming language or pseudo code if you wish) to sort the lap times into ascending order. You should consider how to do it in as few lines of code as possible and using an efficient solution (given that once this goes live the list of lap times will be significantly greater data wise).

To simulate the game detailed above in a computer environment as a C ++ con sole application, follow the steps below in order: Declare a two-dimen sional array of 10 rows and 15 columns that can store integers in the int data type. Each row of this tw o-dimensional array represents a tombala card. Therefore, this series has the capacity to store 10 different tombala cards. Assign 15 unique random integers in the range of 1 (inclusive) to 90 (inclusive) to each row of this array. Prototype for this purpose void CreateCards (int[][15], int); Make use of the sub-function given in the form. The first parameter of this function is the two-dimensional array that stores tombala cards, and the second parameter is the total number of cards. Then print the contents of the series on the screen similar to the following output TOMBALA KARTLARI HAZIRLANIYOR=TOMBALA CARDS ARE PREPARING
Use C#, and explain each step please. Use a one-dimensional array to solve the following problem: Write an app that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display only if it's not a duplicate of a number already read. Provide for the "worst case," in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values after the user inputs each new value.
