As soon as one components fails, the entire system will fail. suppose each component has a lifetime that is exponentially distributed with λ = 0.01 and that components fail independently of one another. define events ai = {ith component lasts at least t hours}, i = 1, . . , 5, so that the ais are independent events. let x = the time at which the system fails—that is, the shortest (minimum) lifetime among the five components. (a) the event {x ≥ t} is equivalent to what event involving a1, . . , a5?

- "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."

step-by-step explanation:

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
