You fit a linear model using the following two-level categorical variables: with the equation: This model produced the following parameter estimates: Another actuary modeled the same underlying data, but coded the variables differently as such: with the equation: Afterwards you made a comparison of the individual parameter estimates in the two models. Calculate how many pairs of coefficient estimates () switched signs, and how many pairs of estimates stayed identically the same, when results of the two models are compared. A 1 sign change, 0 identical estimates B 1 sign change, 1 identical estimate C 2 sign changes, 0 identical estimates D 2 sign changes, 1 identical estimate E The answer is not given by (A), (B), (C), or (D) Exhibit

Choose one option below. You do not need to provide any explanation. When calculating the equivalent resistance of a linear network containing both independent and controlled sources: (a) Independent sources must be set to zero, while controlled sources must be left active; (b) Both independent and controlled sources must be set to zero; (c) Controlled sources must be set to zero, while independent sources must be left active; (d) Controlled sources must be open-circuited, while independent sources must be short- circuited.

Cengage Learning MindTap - Cengage Learning Ace Al Tutor from Numerade CENGAGE MINDTAP Search this course Complete: Chapter 15 Problem Set Based on your scatter diagram, you would expect the correlation to be negative \( \nabla \). The mean \( x \) score is \( M_{X}= \) \( \square \) \( \square \) 6 , and the mean \( \mathrm{y} \) score is \( \mathrm{M}_{\mathrm{Y}}= \) \( \square \) 5. \( \square \) A-Z Now, using the values for the means that you just calculated, fill out the following table by calculating the deviations from the means for \( X \) and \( Y \), the squares of the deviations, and the products of the deviations. \begin{tabular}{ccrrccc} \multicolumn{2}{c}{ Scores } & \multicolumn{2}{c}{ Deviations } & \multicolumn{2}{c}{ Squared Deviations } & Products \\ \hline \( \mathbf{X} \) & \( \mathbf{Y} \) & \( \mathbf{X}-\mathbf{M}_{\mathbf{X}} \) & \( \mathbf{Y}-\mathbf{M}_{\mathbf{Y}} \) & \( \left(\mathbf{X}-\mathbf{M}_{\mathbf{X}}\right)^{\mathbf{2}} \) & \( \left(\mathbf{Y}-\mathbf{M}_{\mathbf{Y}}\right)^{\mathbf{2}} \) & \( \left(\mathbf{X}-\mathbf{M}_{\mathbf{X}}\right)\left(\mathbf{Y}-\mathbf{M}_{\mathbf{Y}}\right) \) \\ 8 & 2 & 3 & -3 & 9 & 9 & -9 \\ 7 & 3 & 2 & -2 & 4 & 4 & -4 \\ 6 & 4 & 1 & -1 & 1 & 1 & -4 \\ 9 & 6 & 4 & 1 & 16 & 1 & -1 \\ 0 & 10 & -5 & 5 & 25 & 25 & 4 \\ \hline \end{tabular} The sum of squares for \( \mathrm{x} \) is \( \mathbf{S S}_{\mathrm{x}}= \) \( \square \) . The sum of squares for \( \mathrm{y} \) is \( \mathrm{SS}_{\mathrm{y}}= \) \( \square \) .

Consider the 2nd Order ODE $x(t)$ k = 1000N/m ............... F(t) = 10N m = 10kg c = 20Ns/m//////// $m\ddot{x}(t) + c\dot{x}(t) + kx(t) = F(t)$ Where, $m$, is the mass, $c$, is the coefficient of damping, $k$, is the spring constant, and, $F(t)$, is the input force. 1. Sensitivity - We will start of this assignment by exploring sensitivity. Consider that this sys- tem operates in a variety of temperatures and as a result the spring constant value varies by $\pm$20%.Consider two possible arrangements of the system, an open loop and a closed loop as shown below Open Loop: F(s) X(s) Closed Loop: F(s) X(s) G(s) G(s) $k_p$ In these systems G(s) is the systems transfer function with F(s) being the input force and X(s) being the output position of the mass. $k_p$ is a proportional controller added into the system that can have any positive value. (a) Calculate the theoretical sensitivity, S, of both the open and closed loop systems to vari- ations in the spring constant k. 1 (b) Find a theoretical expression for the steady state sensitivity of both the open and closed loop systems so variations in the spring constant k. Additionally, provide a theoretical value of $k_p$ based on your calculations that would allow for the steady state value of the system to have less than 1% variation due to temperature.
