6.38. WP n-Hexane is burned with excess air. An analysis of the product gas yields the following dry-basis molar composition: 6.9\% $CO_2$, 2.1\% CO, 0.265\% $C_6H_{14}$ (+ $O_2$ and $N_2$). The stack gas emerges at 760 mm Hg. Calculate the percentage conversion of hexane, the percentage excess air fed to the burner, and the dew point of the stack gas, taking water to be the only condensable species.

A sex discrimination suit alleges that a small college discriminated against women faculty in terms of salaries. A regression study considers the following variables: • Salary (base salary per year (thousands of dollars)) • Senior (seniority at the college (number of years working at the college)) • Gender = 1 for men; 0 for women • Doctorate = 1 for holders of doctorate degree; 0 for others • Rank There are four levels of \"rank\": full professors, associate professors, assistant professors, and instructors. Therefore, there are three indicator variables in the model defined as follows: ? RankD1 = 1 for full professors; 0 for others ? RankD2 = 1 for associate professors; 0 for others ? RankD3 = 1 for assistant professors; 0 for others Below is part of the regression output. Use the output to answer the questions that follow. Coefficients: Estimate Std.

9. A circular loop (in x-y plane) with its center at the origin has radius R and carries current I in a clockwise direction. A long wire laying along y=-2R line in x-y plane carries current 2I in positive direction of x. What is the magnitude and direction of the magnetic field at the origin? Is there a point along y-axis where B=0?

2) Let A be the set of all real numbers except 4. Let B be the set of all real numbers except 2. Let $f(x) = \frac{2x+3}{x-4}$. Prove that $f(x)$ is a bijection from A to B. You will have to do some algebra to prove both parts of the bijection. 3) Evaluate the double sum $\sum_{i=1}^{5} \sum_{j=1}^{4} (5j^2 - 3i^3j)$ 4) Find the first 6 terms of the sequence given by $a_n = 5(a_{n-1})^2 + 3a_{n-2}$ where $a_2 = 2$ and $a_1 = -1$
