In an example presented earlier in this chapter, we noted that, in the united states in 1986, 13.6% of all individuals were poor, 9.3% of all individuals were poor whites (thus 4.3% were poor nonwhites), and 84.8% of all individuals were white (thus 15.2% were nonwhite). from these data we determined that 11.0% of whites were poor and 28.3% of nonwhites were poor. now, suppose that we pick a poor person at random from this population. what is the probability that he or she is nonwhite?

your answer would be 10x - 1

- "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."

their is no graph showing
