An industrial bakery produces two kinds of bread. A loaf of wheat bread weighs 0.8 kg and a loaf of rye bread weighs 1.1 kg . One day, the bakery produces 4680 loaves of bread weighing a total of 4332.1 kg . Use the matrix inverse to determine how many loaves of each type the bakery produced. Part A Set up your linear system so that wheat bread is represented in the first column (variable) and the number of loaves is represented in the first row (equation). Compute the inverse of this system's coefficient matrix, rounding two decimal places. \[ \begin{array}{l} C^{-1}=M=\left[\begin{array}{ll} M_{11} & M_{12} \\ M_{21} & M_{22} \end{array}\right] \\ M_{11}= \\ M_{12}= \\ M_{21}= \\ M_{22}= \end{array} \] Part B The factory produced $ \square $ loaves of wheat bread and $ \square $ loaves of rye bread.

Let $f(x) = 3x^5 - 10x^3 + 15x + a$, where $a$ is some constant. (a) (2 points) Prove that, regardless of the value $a$, $f'(x) > 0$ for all $x$ in $(-1, 1)$. (b) (2 points) Prove that, regardless of the value $a$, the equation $f(x) = 0$ does not have two distinct roots in $[-1, 1]$.

Texts: Step 1: Ensure Permissions on Sensitive Files The /etc/ directory is where system configuration files exist. Start by navigating to this directory with cd /etc/. Inspect the file permissions of each of the following files. You should have already done this during an in-class activity, but double check them now. If any file's permissions do not match the descriptions listed here, update the file's permissions. Permissions on /etc/shadow should allow only root read and write access. Permissions on /etc/gshadow should allow only root read and write access. Permissions on /etc/group should allow root read and write access, and allow everyone else read access only. Permissions on /etc/passwd should allow root read and write access, and allow everyone else read access only. Step 2: Create User Accounts In this step, you'll set up various users in the system. For this exercise, use the useradd command. Research this command to determine how to best use this tool to create the user accounts. The necessary commands do not require that you work from a specific directory. Add user accounts for sam, joe, amy, sara, and admin1. HINT: Make sure that only the admin1 user has general sudo group access. This requires a command that will allow user modifications. Step 3: Create User Group and Collaborative Folder Now, you'll run the commands to fully set up a group on your system. This requires you to create a group, add users to it, create a shared group folder, and set the group folder owners for this shared folder. Add the group engineers to the system. Add users sam, joe, amy, and sara to the managed group. The process is similar to the one you used to add admin1 to the sudo group in the previous step. Create a shared folder for this group: /home/engineers. Change ownership on the new engineers' shared folder to the engineers group. Step 4: Lynis Auditing The final step on your administrator's list involves running an audit against the system in order to harden it. You'll use the system and security auditing tool Lynis to do so. Install the Lynis package to your system if it is not already installed. Check the Lynis documentation for instructions on how to run a system audit. Run a Lynis system audit with sudo. Provide a report from the Lynis output with recommendations for how to harden the system.

approp technol Suppose data made available through a health system tracker showed health expenditures were \$10,348 per person in the United States. Use \$10,348 as the population mean and suppose a survey research firm will take a sample of 100 people to investigate the nature of their health expenditures. Assume the population standard deviation is \$2,500. (a) Show the sampling distribution of the mean amount of health care expenditures in dollars for a sample of 100 people. -500 -250 0 250 500 9848 10098 10348 10598 10848 7848 10348 12848 15348 -250 0 250 500 750 (b) What is the probability the sample mean will be within \$\pm150 of the population mean? (Round your answer to four decimal places.) (c) What is the probability the sample mean will be greater than \$12,600? (Round your answer to four decimal places.) If the survey research firm reports a sample mean greater than \$12,600, would you question whether the firm followed correct sampling procedures? Why or why not? No, because the probability that the sample mean will be greater than \$12,600 is very large. Yes, because the probability that the sample mean will be greater than \$12,600 is very small. No, because \$12,600 is within one standard deviation of \$10,348. Yes, because \$12,600 is not within \$150 of the population mean.
