Answer:

Step-by-step explanation:

This is a normal distribution question with

Mean = 153

Standard Deviation= 10

Since we know that score

Z_{score}=\frac{x- \mu}{ \sigma }

a)

P(x > 150.0)=?

The z-score at x = 150.0 is,

Z = \frac{150-153}{10} \\\\Z=-0.3

This implies that

P(x > 150.0) = P(z > -0.3)

= 1 - P(z < -0.3) = 1 - 0.3820885778110474

P(x > 150) = 0.6179

A person on a runway sees a plane approaching. The angle of elevation from the runway to the plane is 11.1° . The altitude of th
Gnoma [55]

Answer:

The horizontal distance from the plane to the person on the runway is 20408.16 ft.

Step-by-step explanation:

Consider the figure below,

Where AB represent altitude of the plane is 4000 ft above the ground , C represents the runner.  The angle of elevation from the runway to the plane is 11.1°

BC is the horizontal distance from the plane to the person on the runway.

We have to find distance BC,

Using trigonometric ratio,

\tan\theta=\frac{Perpendicular}{base}

Here, \theta=11.1^{\circ} ,Perpendicular AB = 4000

\tan\theta=\frac{AB}{BC}

\tan 11.1^{\circ} =\frac{4000}{BC}

Solving for BC, we get,

BC=\frac{4000}{\tan 11.1^{\circ} }

BC=\frac{4000}{0.196} (approx)

BC=20408.16(approx)  

Thus, the horizontal distance from the plane to the person on the runway is 20408.16 ft
