Assume a plane is flying directly north at 200 mph, but there is a wind blowing west at 23 mph. Part I: Express both the velocit
yuradex [85]
Define i  as a unit vector in the eastern direction.
Define j as a unit vector in the northern direction.

Part I
Because the wind is blowing west, its velocity vector is
 -23i mph or as (-23, 0) mph
Because the plane is traveling north, its velocity vector is
  200j mph or as (0, 200) mph 

Part II
The actual velocity of the plane is the vector sum of the plane and wind velocities.
That is,
200j - 23i or (-23, 200) mph

Part III
The ground speed of the plane is the magnitude of its vector.
The ground speed is
√[200² + (-23)²] = 201.32 mph

The ground speed of the plane is 201.3 mph (nearest tenth)

Not:
The direction of the plane is
 tan⁻¹ 23/200 = 6.56° west of north.

In a random sample of 64 people, 48 are classified as 'successful.' Determine the sample proportion of 'successful' people.
hichkok12 [17]

Answer:

The sample proportion of 'successful' people is \frac{3}{4}.

Step-by-step explanation:

The sample consist of 64 people and 48 of them are 'successful'. Hence, the proportion of 'successful' people is:

p = \frac{n}{N}

Where:

N - People that forms the sample, dimensionless.

n - People classified as 'successful', dimensionless.

Given that n = 48 and N = 64, the sample proportion of 'successful' people is:

p = \frac{48}{64}

p = \frac{3}{4}

The sample proportion of 'successful' people is \frac{3}{4}.
