A student performed a Kirby-Bauer test and measured the diameter of the zone of inhibition for antibiotic X on both a Staphylococcus aureus (Gram positive) plate, and an Escherichia coli (Gram negative) plate. They found no zone of inhibition on the S. aureus plate, but the diameter of the zone of inhibition was greater than the standard threshold for the E. coli plate. For E. coli, is antibiotic X effective or ineffective? effective ineffective

Sometimes a child gets a reward after reading for ten minutes, sometimes he gets a reward after reading for fifteen minutes, and other times he gets a reward after reading for twenty minutes. He never knows how much time he needs to read before getting a reward! This is an example of which kind of partial reinforcement schedule? O variable ratio O variable interval O fixed interval O fixed ratio Corrected text: Sometimes a child gets a reward after reading for ten minutes, sometimes he gets a reward after reading for fifteen minutes, and other times he gets a reward after reading for twenty minutes.

Problem 4 (20 pt) One side of a metal plate is in contact with a heat sink of constant temperature $T_0$. Initially the temperature throughout the plate is equal to that of the heat sink. Then electric current is passed through the plate, which results in internal heat generation $\dot{q}$. Concurrently, air with ambient temperature $T_\infty$ was blown on the other side of the plate (see figure below). For this scenario, determine the following: (a) Write down the appropriate form of the heat equation (b) Apply appropriate boundary and initial conditions (c) Sketch the steady state temperature distribution within the plate before and after the electric current is turned on (assuming that $T_\infty > T_0$)

A particular professor has noticed that the number of people, P, who complain about his attitude is dependent on the number of cups of coffee, $n$, he drinks. From eight days of tracking he compiled the following data: \begin{tabular}{|l|c|c|c|c|c|c|c|c|} \hline People (P) & 12 & 8 & 8 & 6 & 7 & 4 & 4 & 4 \\ \hline Cups of coffee ($n$) & 1 & 2 & 2 & 3 & 3 & 4 & 5 & 5 \\ \hline \end{tabular} Unless otherwise stated, you can round values to two decimal places. a) Using regression to find a linear equation for $P(n)$ $P(n) = $ b) Find the correlation coefficient $r = $ c) Does the correlation coefficient indicate a strong linear trend, a weak linear trend, or no linear trend?
