Exit Card
Twenty students were randomly selected to answer if they rode
the bus to school and if they arrived to their first class on time.
Of the 15 who rode the bus, 12 arrived on time.
Two of those who did not ride the bus arrived on time.
1. Make a two-way frequency table to show the information.
2. What is the conditional frequency of a student who rides the
bus being late to class first period?

do you have the measurements?

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
