In a cannery, assembly lines I, II, and III account for 40, 40, and 20 percent of the total output. If 0.4 percent of the cans from assembly line I are improperly sealed, and the corresponding percentages from assembly line II and III are 0.3 percent and 0.3 percent, what is the probability P that a can produced by this cannery will be improperly sealed, and what is the probability Q that an improperly sealed can will have come from assembly line I?a. P = 0.0034; Q = 0.7353.

b. P = 0.00755; Q = 0.3434.

c. P = 0.006875; Q = 0.3434.

d. P = 0.00825; Q = 0.364.

e. P = 0.006875; Q = 0.3636.

- "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."
