A system (in a container) consists of an unknown number of components in two phases. You are given the temperature, one mole fraction in the liquid, and one mole fraction in the vapour and you are told that this is enough for fully defining the system. What is the number of components that are present? The question is ill-posed. 2 1 3 Use Gibbs' Phase Rule.

You walk into a casino with $ 1000 dollars to spend. The casino owner offers you a one-time special game. It costs $ 1000 dollars to play. The chance of winning is 75 % and the payoff is $ 2000 (meaning after playing the game, you will have spent $ 1000 and won $ 2000 ). Given that your utility function with respect to wealth is U(w)=w^∧ 2 should you play the game? Are you risk-loving, risk-neutral, or risk-averse? Yes: risk-loving No: risk-averse Yes: risk-neutral No; risk-loving

(10 points) This problem is related to Problem 9.25-9.27 in the text. The periodic function $s_0(t)$ with period 24 given by $\s_0(t) = \begin{cases} 0 & \text{if } -12 \le t < -2\\ 1 & \text{if } -2 \le t < 2\\ 0 & \text{if } 2 \le t < 12. \end{cases}$ has the Fourier series defined by and for $n \ne 0$ $S_0(0) = 0.166667$ $S_0(n) = \frac{0.166667 \cdot \sin(n\pi4/24)}{n\pi4/24}$ Use linearity and the shifting property to find the Fourier Series for $s(t)$, defined by $s(t) = \begin{cases} 0 & \text{if } -12 \le t < 0.5\\ 6 & \text{if } 0.5 \le t < 4.5\\ -1 & \text{if } 4.5 \le t < 8.5\\ 0 & \text{if } 8.5 \le t < 12. \end{cases}$ $S(0) = \text{________}$ and for $n \ne 0$ $S(n) = \text{________}$

The scores on a placement test given to college freshmen for the past five years are approximately normally distributed with a mean $\mu = 78$ and a variance $\sigma^2 = 8$. Would you still consider $\sigma^2 = 8$ to be a valid value of the variance if a random sample of 24 students who take the placement test this year obtain a value of $s^2 = 24$? Click here to view page 1 of the table of critical values of the chi-squared distribution Click here to view page 2 of the table of critical values of the chi-squared distribution Since the statistic $\chi^2 = 69.000$ is less than $\chi^2_{0.10}$ conclude that the value is valid. (Round to three decimal places as less than $\chi^2_{0.10}$ greater than $\chi^2_{0.01}$
