Answer: A3. The counting principle lets
you multiply
<span>The fundamental
counting principle is a method for determining how many ways that a combination
of events can occur. For example, if the
first event can occur 2 ways, the second event can occur 3 ways, and the third
event can occur 4 ways, then you can find out the number of unique combinations
by multiplying: 2 * 3 * 4 = 24 unique combinations.</span>
<span>This
multiplication method works any time you have several options or criteria like color,
shape, and design and each of those factors can be combined with each other in
any way possible. </span>

Answer:
about 151 feet
Step-by-step explanation:
The height of the ball at a time of 3.1 seconds is given by Charlize's equation as ...
h(3.1) = -16(3.1)^2 +3 = -150.76 . . . feet
The well is about 151 feet deep.
_____
<em>Comment on this measurement</em>
The speed of sound is sufficiently slow that it will make a difference in the time Charlize records. She would get a more accurate measurement if she were able to <em>see</em> the ball hit bottom.
