HW 6 - Continuous Probability Distributions The electric-vehicle manufacturing company Tesla estimates that a driver who commutes 50 miles per day in a Model S will require a nightly charge time of around 1 hour and 45 minutes (105 minutes) to recharge the vehicle's battery (Tesla company website). Assume that the actual recharging time required is uniformly distributed between 90 and 120 minutes. a. Give a mathematical expression for the probability density function of battery recharging time for this scenario. A. $f(x) = \begin{cases} \frac{1}{30} & \text{for } 90 \le x \le 120 \\ 0 & \text{elsewhere} \end{cases}$ B. $f(x) = \begin{cases} \frac{1}{15} & \text{for } 90 \le x \le 120 \\ 0 & \text{elsewhere} \end{cases}$ C. $f(x) = \begin{cases} \frac{1}{15} & \text{for } 90 \le x \le 105 \\ 0 & \text{elsewhere} \end{cases}$ The correct answer is: - Select your answer - b. What is the probability that the recharge time will be less than 110 minutes (to 3 decimals)? c. What is the probability that the recharge time required is at least 100 minutes (to 3 decimals)? d. What is the probability that the rech

Show that the function is a one-to-one correspondence. $f: \mathbb{R} \to \mathbb{R}$ given by $f(x) = mx + b$, $m \ne 0$ Proof. i. Suppose $x, y \in \mathbb{R}$ and $f(x) = f(y)$. Then $mx + b = my + b$, so $mx = my$. Because $m \ne 0$, we have $x = y$. Therefore $f$ is one-to-one. ii. Let $z \in \mathbb{R}$. Choose $t = \frac{z - b}{m}$. Because $m \ne 0$, $t \in \mathbb{R}$. Then $f(t) = m(\frac{z - b}{m}) + b = z$. Therefore, $f$ is onto $\mathbb{R}$.

Problem 1. A spring of stiffness k=500(N)/(m) is mounted against the 10-kg block. If the block is subjected to the force of F=500N, determine its velocity at s=0.5m. When s=0, the block is at rest and the spring is uncompressed. The contact surface is smooth. Problem 2 (Figure A). .. ... The 10 -lb block has a speed of 4f(t)/(s) when the force of F=(8t^(2))lb is applied. Determine the velocity of the block when t=2s. The coefficient of kinetic friction at the surface is mu _(k)=0.2.

Data from 240 to 280 in the Excel list. In the class, we analyzed bank loan applications. As a reminder, we had 3 data tables that contained loan application data, client locations, and client credit scores. Using this information as an input, complete the following tasks. Task 1: Statistics Each student should use only the assigned subset of data to complete this task. The data rows assigned to each student are published in the portal together with the Excel data file from the class. (see file Assignment 1 - task distribution - section 64) Calculate the measures of central tendencies for the credit score values: mean, mode, median, standard deviation, min, max Task 2: Analysis in Excel Using pivot tables in Excel, answer the following questions: What is the average credit score of applicants in different cities? What is the average distributed loan amount in different cities (per currency)? Task 3: Hypothesis Testing Using the same subset of data assigned to you, please answer the following scenario. Choose your preferred confidence level for hypothesis testing (5% is standard). Interpret the results. The manager in the lending department believes that on average the credit score of the bank applicants is greater than 650. You have access only to a limited number of applications (your subset of data) but need to answer if this can be true for the whole population (all applicants). For the same scenario, please calculate the confidence interval of the average credit score using your sample data. Submission format Please prepare in the memo format an MS Word document with answers to the questions above submitted through the portal. Up to 2 pages. For the calculations done in Excel make screenshots and include them directly in the memo.

5. Geiger-Nuttals rule $^{188}Os$ is energetically allowed to decay to $^{184}W$ by emitting an $\alpha$ particle. What would you say about this decay when you calculate its half-life using the following expression for the Geiger-Nuttals rule: $\log t_{1/2} + 1.28 \sqrt{Z_{daughter} R_{daughter}} = 1.70 Z_{daughter} \frac{1}{\sqrt{Q_{\alpha}}} + C$ With $t_{1/2} [s]$; $R [fm]$, and $Q_{\alpha} [MeV]$ and the knowledge that $^{232}Th \rightarrow ^{228}Ra + \alpha$; $t_{1/2} = 1.4 \times 10^{10} y$, and $T_{\alpha} = 4.00 MeV$
