B) Find the median queuing timeplease help!!!!
1 answer:
Answer:
11 minutes.
Step-by-step explanation:
To find the median queing time from the cumulative frequency curve, we find
and trace it on the cumulative frequency curve.
From the graph, that total frequency is 100.
Half of this 50.
We trace the 50th item.
First locate 50 on the vertical axis and trace to the horizontal axis.
This corresponds to 11.
Note that each box is 0.5 units on the queing time axis.

Answer:
d) one solution; (4, 1)
Step-by-step explanation:
It often works well to follow problem directions. A graph is attached, showing the one solution to be (4, 1).
_____
You know there will be one solution because the lines have different slopes. Each is in the form ...
y = mx + b
where m is the slope and b is the y-intercept.
The first line has slope -1 and y-intercept +5; the second line has slope 1 and y-intercept -3. The slope is the number of units of "rise" for each unit of "run", so it can be convenient to graph these by starting at the y-intercept and plotting points with those rise and run from the point you know.
