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.
Y= 15x + 25 - slope intercept
y-25=15x - point-slope

Answer:
The rectangle is 16*18
Step-by-step explanation:
The area of a rectangle is length * width and the perimeter is 2 times length * width
A = l*w
P = 2(l+w)
Replacing A and P
288 = l*w
68 = 2(l+w) => 34 = l+w => 34 - w = l
replacing l in the area
288 = (34 - w) w
w^2 - 34w + 288 = 0
(w - 16)(w - 18)
w = 16
w = 18
replacing in 34 - w = l
you get that when w = 16, l = 18 and when w = 18, l = 16
Answer:
x ≈ 11.3
Step-by-step explanation:
Using the sine ratio in the right triangle
sin45° =
=
( multiply both sides by x )
x × sin45° = 8 ( divide both sides by sin45° )
x =
≈ 11.3
