1. A student gathered the data seen in the table below.
   
   1. Plot the soap data on the graph.
   2. __________ __________ Calculate the density of the soap. Include the units with your answer.
   3. Based on the slope, will the soap [float] OR [sink]?
   4. Based on the slope, is this likely to be [Ivory] OR [Dial] soap?
2. Spring 2013 I was puzzled by a bar of blue Lux Wake Me Up soap. I gathered data and made the chart shown based on the data. The slope was 0.9853 g/cm³. When placed in water the soap sank.
   1. What was unexpected about this result?
      
   2. Explain why this might have happened.
3. A RipStik was ridden three times at three different velocities (speeds). The data was gathered in the table seen below.
   
   1. Plot the data using circles, squares, and diamonds for A, B, and C respectively.
   2. __________ __________ Calculate the velocity (speed) of RipStik run A. Do not forget to include the units!
   3. __________ __________ Calculate the velocity (speed) of RipStik run B.
   4. __________ __________ Calculate the velocity (speed) of RipStik run C.
   5. __________ Which RipStik run is the fastest (A, B, or C)?
   6. __________ Which RipStik run is the slowest (A, B, or C)?
   7. __________ __________ Based on the slope and intercept, how far will RipStik A travel in 23 seconds?
   8. __________ __________ Based on the slope and intercept, how long in seconds for RipStik B to travel 6000 centimeters?

$\text{slope}=\frac{(y_2-y_1)}{(x_2-x_1)}$
Volume V = length l × width w × height h
mass m = density ρ × Volume V
$\rho =\frac{m}{V}$

$ѵ=\frac{\Delta d}{\Delta t}$
distance d = velocity ѵ × time t
