a qualitative graph
a discrete graph
a bar graph
a histogram

 Second option is correct.

Step-by-step explanation:

The graph which models the speed of a roller coaster over the full two minutes is a discrete graph.

Because the discrete function allow the value of x to be only at certain point in the interval, and we have given that it covers in two minutes only.

So, it takes upto 2 minutes only.

So, The best type of graph is a "discrete graph".

Hence, Second option is correct.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

5/20 so 25%
