Apersonnel director interviewing 11 senior engineers for four job openings has scheduled six interviews for the first dayand five for the second day of interviewing. assume that the candidates are interviewed in random order. a. what is the probability that x of the top four candidates are interviewed on the first day? b. how many of the top four candidates can be expected to be interviewed on the first day?

step-by-step explanation:

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

- "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."
