When a participant takes part in the Special Olympics, each person receives a number. The chart shown represents the first twenty people labeled by their participation number and the number of gold medals each participant won.

$$\begin{matrix} \text{Participation Number} & \text{Gold Medals Won}\\ \text{001} & \text{6}\\ \text{002} & \text{14}\\ \text{003} & \text{1}\\ \text{004} & \text{6}\\ \text{005} & \text{0}\\ \text{006} & \text{0}\\ \text{007} & \text{9}\\ \text{008} & \text{1}\\ \text{009} & \text{1}\\ \text{010} & \text{9}\\ \text{011} & \text{5}\\ \text{012} & \text{10}\\ \text{013} & \text{1}\\ \text{014} & \text{2}\\ \text{015} & \text{2}\\ \text{016} & \text{5}\\ \text{017} & \text{4}\\ \text{018} & \text{3}\\ \text{019} & \text{4}\\ \text{020} & \text{2}\\ \end{matrix}$$

Interpret the IQR.

The numbers of children C (in millions) participating in the Federal School Breakfast Program from 2000 through 2009 can be approximated by the model $C=7.50(1.04)^{t}, \quad 0 \leq t \leq 9$ where t represents the year, with t=0 corresponding to 2000. (a) Use the model to estimate the numbers of children participating in the Federal School Breakfast Program in 2006 and 2008. (b) Use the model to predict the numbers of children who will participate in the Federal School Breakfast Program in 2014 and 2015.

Mention two uses of the Clapeyron equation.

Solve the logarithmic equation algebraically. Approximate the result to three decimal places. $\ln \sqrt{x+2}=1$

The remotely-controlled robotic vehicle of previous problem is now connected to a 200-m tether which has a slight negative buoyancy in that a net downward force of 0.025 N per meter of its length acts on it. Determine the horizontal and vertical components of thrust which must be produced in order to hold the vehicle in the position shown. The vehicle itself is neutrally buoyant.

A hole whose cross-section is a square of side 2 is punched through the middle of a ball of radius 2. Find the volume of the remaining part of the ball.

What is the heat capacity rate? What can you say about the temperature changes of the hot and cold fluids in a heat exchanger if both fluids have the same capacity rate? What does a heat capacity of infinity for a fluid in a heat exchanger mean?

The device shown in the figure is designed to drive brads into picture-framing material. For a gripping force of 10 lb on the handles, determine the force F exerted on the brad.

What is terminal velocity? How is it determined?
