Answer:
0.5 or 50%
Step-by-step explanation:
For any given value of 'x' representing the time between arrivals of two customers. If 0 < x <120, then the cumulative distribution function is:
Therefore, the probability that the time between the arrivals of two customers will be more than 60 seconds is determined by:
The probability is 0.5 or 50%.
The graph illustrated is divided into three seperate sections namely <em>A, B and C,</em> the short story culled from the graph is described thus:
Rate of change or slope = (Rise/ Run)
<u>SECTION A:</u><u> </u>
Slope = (40 - 0) ÷ (20 - 0) = 40/20 = 2
Distance traveled = 50 meters
<u>SECTION B</u> :
This section gives an horizontal line, hence, the slope is 0.
Distance covered = 0 ; as there was no change in the distance over the period of time.
<u>SECTION</u><u> </u><u>C</u><u>:</u>
Slope = (80 - 50) ÷ (70 - 60) = 30/10 = 3
The total distance traveled = 80 - 50 = 30 meters
<u>The total </u><u>distance</u><u> </u><u>and</u><u> </u><u>time spent traveling</u> :
Total distance traveled = (50 + 30) = 80 meters
Total time spent = 70 seconds (<em>time at the 80 meter mark</em>)
Hence, the story.
