Design an experiment to find out the effect of water temperature on frog egg development.

Silicon is the second most abundant element in the Earth's crust, and its compounds can be as ordinary as beach sand. However, silicon also plays an indispensable role in modern devices such as computers, cell phones, semiconductors, and solar panels. A recent technology incorporates silicon in nanometer-sized particles called quantum dots that act as luminescent labels for pancreatic cancer cells. Identify the electron configuration of a silicon atom.

Are the marks one receives in a course related to the amount of time spent studying the subject? To investigate this mysterious possibility, a student took a random sample of 10 students who had enrolled in an accounting class last semester. He asked each to report his or her mark in the course and the total number of hours spent studying accounting. These data are listed here: Study

$$\begin{array}{rllllllllll}\text { time } & 40 & 42 & 37 & 47 & 25 & 44 & 41 & 48 & 35 & 28 \\ \text { Marks } & 77 & 63 & 79 & 86 & 51 & 78 & 83 & 90 & 65 & 47\end{array}$$

Calculate the covariance.

An upscale department offers its customers free gift wrapping on any day that they spend at least $\$ 100$. The store offers 5 box sizes (XS, S, M, L, XL), 6 wrapping themes (birthday, wedding, baby girl, baby boy, anniversary, and all-occasion), and 3 styles of bow (classic, modern, and jazzy).

What is the probability that any wrapped package will be in a large box?

As part of the Great Plains of the United States, the topography of the state of Kansas is relatively flat. On the other hand, portions of the state of Colorado are mountainous. Describe how the contour interval and the contour lines might vary on topographic maps of these two states.

Design a controlled experiment to determine whether earthworms are more attracted to perfume or to vinegar.

The Modern Language Association plans a three-day meeting. The program committee requests 15 overhead projectors for the first day, 28 for the second day, and 19 for the third day. Projectors may be rented for a single day for $17, and they may be rented for two consecutive days for$30. How many should be rented for a single day and how many should be rented for two consecutive days to minimize rental costs?

True/False: Read design books alone will make you a great designer.

Recall the table discussed before that gives the price of a gallon of regular gasoline in the United States (in dollars) for the years $2003$ through $2011$. Another table discussed gives the price of a gallon of regular gasoline in the United States (in dollars) for the years $1990$ through $2002$.

By using $1990$ as the base year, construct a simple index for the prices of a gallon of regular gasoline in both tables.

A modern jet engine Operates so that the fuel is sprayed into air at P, tighter than the fuel critical point. Assume we have a rich mixture of 50% n-octane and 50% air by moles at 500 K and 3.5 MPa near the nozzle exit. Do I need to treat this as a real-gas mixture, or is an ideal-gas assumption reasonable? To answer, find Z and the enthalpy departure for the mixture assuming Kay's rule and the generalized charts.

The Enormous State University’s Accounting Society has decided to produce a version of the ballet Swan Lake, in which all the female roles (including all of the swans) will be danced by men, and vice versa. Here are the main characters: Prince Siegfried. Prince Siegfried’s Mother. Princess Odette, the White Swan. The Evil Duke Rotbart. Odile, the Black Swan. Cygnet #1, young swan. Cygnet #2, young swan. Cygnet #3, young swan. The ESU Accounting Society has on hand a total of 4 female dancers and 12 male dancers who are to be considered for the main roles. How many possible casts are there?

Listed below are nine technical accounting terms:

$$\begin{array}{lll}\text { Variable costs } & \text { Relevant range } & \text { Contribution margin } \\ \text { Break-even point } & \text { Fixed costs } & \text { Semivariable costs } \\ \text { Economies of scale } & \text { Sales mix } & \text { Unit contribution margin }\end{array}$$

Each of the following statements may (or may not) describe one of these technical terms. For each statement, indicate the accounting term described, or answer "None" if the statement does not correctly describe any of the terms.

e. Unit sales price minus variable cost per unit.
