Consider the following table of data. Complete parts (a) through (c) below. X 1 2 3 4 y 2.00 2.00 2.00 2.40 a. Calculate the correlation coefficient. r = (Type an integer or decimal rounded to four decimal places as needed.) b. Sketch a graph of the data. Choose the correct answer below. OA. Ay OB. OC. OD. Ay Ay Ay 5- 5- 5- 5- 4- 4- 4- 4- 3- 3- 3- 3- 2- 2- 2- 2- 1- 1- 1- 1- 0- 0- 0- 0- 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 c. Based on how closely the data fits a straight line, is the answer to part (a) surprising? Discuss the extent to which the correlation coefficient describes how well the data fit a horizontal line. A. It is surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 0. The correlation coefficient is positive, leading one to expect decreasing line, not a horizontal line. B. It is surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 1 or $-1$. The correlation coefficient is positive, leading one to expect a decreasing line, not a horizontal line. C. It is not surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 0. The correlation coefficient is positive, leading one to expect an increasing line, not a horizontal line. D. It is not surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 1 or $-1$. The correlation coefficient is positive, leading one to expect an increasing line, not a horizontal line.

1. Let the following matrices be coefficient matrices of a system of linear equations. Compute the rank of each of the following matrices. For each matrix, what can you say about the number of solutions of the corresponding system i) when the right-hand side is $b_1 = b_2 = \dots = b_m = 0$; and ii) for any $b \in \mathbb{R}^m$. (a) $\begin{bmatrix} 2 & -4 & 2 \ -1 & 2 & 1 \ \end{bmatrix}$, (b) $\begin{bmatrix} 1 & 6 & -7 & 3 \ 1 & 9 & -6 & 4 \ 1 & 3 & -8 & 4 \ \end{bmatrix}$, (c) $\begin{bmatrix} 1 & 6 & -7 & 1 \ 1 & 9 & -6 & 2 \ 1 & 3 & -8 & 5 \ \end{bmatrix}$. 2. Let $A = \begin{bmatrix} 1 & 1 \ 0 & 1 \ \end{bmatrix}$. Find a formula for $A^n$, whenever $n$ is a positive integer. (Clearly state your claim about $A^n$ and prove your claim using induction.)

Thank you for using the module readings, videos, and other learning materials to address the prompts below. Please be especially attuned to using events and evidence to make your analysis sharper and more fully formed. Discussion prompts Please respond to the following questions in your initial post: Discuss the intelligence community and the various agencies tasked with counterterrorism efforts. What are some of the challenges these agencies currently face with respect to homeland security and evolving threats? As you have learned, there are numerous homeland security organizations that perform immigration and customs enforcement services. Select one of those agencies and explain how it supports the balance of protecting the nation’s borders with the freedom of movement of legitimate travelers and goods. What are the challenges in maintaining this balance with new and emerging security threats?

12:29 LTE CS112_Project4_IO_changes 2 of 2 CSCI 112: Programming Project 4 Due Date: Sunday March 31 by 11:59 pm If your program does not compile, you will not receive any points on this project. You will write a program to keep up with customers. In this project, the classes are Customer, Item, and Purchase. The Customer class has attributes for name and credit card number. The Item class has an attribute for item amount. The Purchase class has attributes for the date of purchase, a Customer object, a list of Items (the list can be an array or ArrayList), and a total amount for the Purchase items. The driver class, PDriver, should only have the main method. It should have a list of Purchases (again, the type of list can be an array or ArrayList, it's up to you). You will need to read through the provided text file and add the information to your list. Your program will need to allow the user to add items to a Purchase, display the items in a Purchase, or exit the program. Late programs will have points deducted per day late. If you do not submit your program, you will not receive any credit. If you need assistance, please ask for help.
