At a car and truck dealership, the probability that a vehicle is white is 0.25.
the probability that it is a van is 0.09. the probability that it is a white van is
0.04.
what is the probability that a vehicle is white, given that the vehicle is a van?
round your answer to two decimal places.

- "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."

what is the model?
