Answer:
Boxplot A
Step-by-step explanation:
Given the data:
22, 25, 50, 58, 28, 24, 25, 51, 43, 32, 49, 38
We should obtain the 5 number summary and check which boxplot correctly displays the information :
Reordered data : 22, 24, 25, 25, 28, 32, 38, 43, 49, 50, 51, 58
. Maximum = 58
Minimum = 22
Lower quartile : 1/4(n+1)th term
n = 12
1/4(13)th term = 3.25
(3rd + 4th) = (25 + 25) /2 = 25
Median :
1/2(13)th = 6.5th term
(32 + 38) /2 = 35
Upper quartile :
3/4(13)th term 9.75 term
(49 + 50) / 2
= 49.5

Answer:
Altitude of the plane is 0.5 miles.
Step-by-step explanation:
From the figure attached,
An airplane A is at height h miles observes a small airstrip at D and a factory at F, 4.8 miles apart from D.
Angle of depressions for the airstrip is 13.1° and the factory is 4.1°.
We have to calculate the airplane's altitude h.
From ΔABF,
tan4.1 =
h = 0.07168(x + 4.8) -----(1)
From ΔABD,
tan13.1 =
h = 0.2327x -----(2)
From equation (1) and (2),
0.07168(x + 4.8) = 0.2327x
0.2327x - 0.07168x = 4.8×0.07168
0.161x = 0.344
x = miles
From equation (2),
h = 0.2327×2.137
h = 0.4972 miles
h ≈ 0.5 miles
Therefore, 0.5 miles is the altitude of the plane.
