Lesson 2: Practice Problems

Problem 1

In hockey, a player gets credited with a “point” in their statistics when they get an assist or goal. The table shows the number of assists and number of points for 15 hockey players after a season.

Make a scatter plot of this data.

Make sure to scale and label the axes.

assists	points
$22$	$28$
$16$	$18$
$46$	$72$
$19$	$29$
$13$	$26$
$9$	$13$
$16$	$22$
$8$	$18$
$12$	$13$
$12$	$17$
$37$	$50$
$7$	$12$
$17$	$34$
$27$	$58$
$18$	$34$

Problem 3

When is it better to use a table? When is it better to use a scatter plot?

Problem 4 From Unit 5 Lesson 17

There are many cylinders with radius 6 meters. Let $(h)$ represent the height in meters and $(V)$ represent the volume in cubic meters.

Write an equation that represents the volume $(V)$ as a function of the height $(h)$ .
Sketch the graph of the function, using 3.14 as an approximation for $π$ .
If you double the height of a cylinder, what happens to the volume? Explain this using the equation.
If you multiply the height of a cylinder by $\frac{1}{3}$ , what happens to the volume? Explain this using the graph.
