Determine whether each of following statements can be inferred from the fact that Shortest-Path and Shortest-Teleport-Path linear-time reduces to one another. For simplicity, assume E ≥ V • [True or False] If there exists an E log log E algorithm for Shortest-Teleport-Path, then there exists an E log log E algorithm for Shortest-Path • [True or False] If there exists an E log log E algorithm for Shortest-Path, then there exists an E log log E algorithm for Shortest-Teleport-Path • [True or False] If there does not exist a linear-time algorithm for Shortest-Path, then there does not exists a linear-time algorithm for Shortest-Teleport-Path • [True or False] If there does not exist a linear-time algorithm for Shortest-Teleport-Path, then there does not exists a linear-time algorithm for Shortest-Path

Question 1: GHW_Thermo_IX-1 Ammonia can be produced by the reaction of hydrogen gas and nitrogen gas, as shown below: $N_2(g) + 3H_2(g) \iff 2NH_3(g)$ Given that the standard free energy of formation ($\Delta G^\circ_f$) of $NH_3(g)$ is -104 kJ/mol at 302 K, calculate the equilibrium constant, K, at this temperature. To express an answer in scientific notation, use the following format: 1.23 x 10^45 = 1.23e45 K = number (rtol=0.01, atol=1e-08) Hint #1

2. (10 points) Conditional Expectation Suppose $X \sim Exp(\lambda)$ for some $\lambda > 0$, and given $X = x$, $Y \sim Pois(x)$. Recall the pdf of $X \sim Exp(\lambda)$ is $f(x) = \lambda e^{-\lambda x}$ for $x > 0$, and the pmf of $X \sim Pois(\lambda)$ is $f(x) = \frac{e^{-\lambda}\lambda^x}{x!}$ for $x = 0, 1, \dots$. Also recall the mean and the variance of $Exp(\lambda)$ are $1/\lambda$ and $1/\lambda^2$ respectively. (a) (5 pts) Find the joint pdf/pmf $f_{X,Y}(x, y)$. (b) (5 pts) Find $E[Y]$ and $V(Y)$. (c) (5 extra credit pts) Find $E[X|Y]$.
