A random variable X has the discrete uniform distribution \[ f(x ; k)=\left\{\begin{array}{lr} 1 / k & : x=1,2, \ldots, k \\ 0 & : \text { otherwise } \end{array}\right. \] The moment generating function of X is: 0. \( \frac{e^{t}\left(1+e^{k t}\right)}{k\left(1-e^{t}\right)} \) \( \frac{e^{t}\left(1-e^{k t}\right)}{k\left(1-e^{t}\right)} \) \( \frac{e^{t}\left(1-e^{k t}\right)}{k\left(1+e^{t}\right)} \) \( \frac{e^{t}\left(1+e^{k t}\right)}{k\left(1+e^{t}\right)} \)

\[ Q_{t}^{D}=\alpha_{0}+\frac{\alpha_{1} \beta_{0}-\alpha_{1} \alpha_{0}}{\alpha_{1}-\beta_{1}}-\frac{\alpha_{1} \alpha_{2} I_{t}}{\alpha_{1}-\beta_{1}}+\frac{\alpha_{1} u_{2}-\alpha_{1} u_{1}}{\alpha_{1}-\beta_{1}}+\alpha_{2} I_{t}+u_{1} \] We observe the term \( \alpha_{0} \) is present in two places: once on its own and once as p: of the fraction multiplied by \( \alpha_{1} \). We can factor \( \alpha_{0} \) out to combine these terms: \[ \alpha_{0}+\alpha_{1}\left(\frac{-\alpha_{0}}{\alpha_{1}-\beta_{1}}\right)=\alpha_{0}\left(1-\frac{\alpha_{1}}{\alpha_{1}-\beta_{1}}\right) \] Now, we can further simplify the expression within the parentheses: \[ 1-\frac{\alpha_{1}}{\alpha_{1}-\beta_{1}}=\frac{\alpha_{1}-\beta_{1}}{\alpha_{1}-\beta_{1}}-\frac{\alpha_{1}}{\alpha_{1}-\beta_{1}}=\frac{\left(\alpha_{1}-\beta_{1}\right)-\alpha_{1}}{\alpha_{1}-\beta_{1}}=\frac{-\beta_{1}}{\alpha_{1}-\beta_{1}} \] Substituting this back into the original expression, we get: \[ \alpha_{0}\left(\frac{-\beta_{1}}{\alpha_{1}-\beta_{1}}\right) \]

For the matrix M=([2,0,-1],[0,3,0],[-1,0,2]) (a) List the eigenvalues in increasing order, including any that are repeated. For example, if they are 1,1 and 0, you would enter 0,1,1 (b) Enter a basis for the eigenspace that corresponds to the lowest eigenvalue. For example, if the basis is {(1,2),(3,4)}, you would enter 1,2 3,4 (c) Enter a basis for the eigenspace that corresponds to the highest eigenvalue. For example, if the basis is {(1,2),(3,4)}, you would enter 1,2 3,4 (d) Find a matrix P such that P^(-1)MP=D, where D is a diagonal matrix. For this question, order your eigenvalues from lowest to greatest, that is λ_(1)<=λ_(2)<=λ_(3). To enter a matrix click on the 3x3 grid of squares below. Next select the exact size of the matrix you want. Then change the entries in the matrix to the entries of your answer. If you need to start over then click on the trash can.

1. Consider an electron, initially in state $|\uparrow\rangle$, which is placed in a magnetic field $\vec{B}_0 = 1 \text{ T}\hat{z}$. (a) A second magnetic field is then turned on perpendicular to the first: $\vec{B}_1 = 0.2 \text{ T}\hat{x}$. What is the maximum probability that the spin will \"flip\", if measured by an $S_z$ analyzer after a certain time?
