Distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.
<h3><u>Solution:</u></h3>Given that
Height of position of pilot from the ground = 30000 feet
Angle of depression when he looks down at runway = 6o
Need to measure along the ground, distance between runway and pilot that is horizontal distance between runway and pilot.
Consider the figure attached below
D represents position of runway.
P represents position of pilot.
PG represents height of position of pilot from the ground that means PG = 30000 feet
PH is virtual horizontal line and HPD is angle of depression means ∠ HPD = 6 degree
AS DG and HP are horizontals, so DG is parallel to HP.
=> ∠ HPD =∠ PDG = 6 degree [ Alternate interior angle made by transversal PD of two parallel lines ]
We need to calculate DG
Consider right angles triangle PGD right angles at G
As one foot = 0.000189 miles
Hence distance between runway and pilot position along the ground is 285430.9336 feet that is 53.9464 miles.
Answer:
Step-by-step explanation:
From the question we are told that:
Sample size
N0 of Large
N0 of Small
N0 large Green
N0 of small White
Therefore
Number of green marbles
Number of green marbles
Generally the Number of both small and green Marble is
Generally the probability that it is small or green P(S&G) is mathematically given by
