A survey found that​ women's heights are normally distributed with mean 63.2 in. and standard deviation 2.4 in. The survey also
Effectus [21]

Answer: 99.51%

Step-by-step explanation:

Given : A survey found that​ women's heights are normally distributed.

Population mean : \mu =63.2  \text{ inches}

Standard deviation: \sigma= 2.4\text{ inches}

Minimum height = 4ft. 9 in.=4\times12+9\text{ in.}=57\text{ in.}

Maximum height = 6ft. 2 in.=6\times12+2\text{ in.}=74\text{ in.}

Let x be the random variable that represent the women's height.

z-score : z=\dfrac{x-\mu}{\sigma}

For x=57, we have

z=\dfrac{57-63.2}{2.4}\approx-2.58

For x=74, we have

z=\dfrac{74-63.2}{2.4}\approx4.5

Now, by using the standard normal distribution table, we have

The probability of women meeting the height requirement :-

P(-2.58

Hence, the percentage of women meeting the height requirement = 99.51%

Given a mean earth radius of 20,906,000 ft, and an observation latitude of n 42 degrees, what is the arc distance of one second
murzikaleks [220]

Answer:

  • arc second of longitude: 75.322 ft
  • arc second of latitude: 101.355 ft

Explanation:

The circumference of the earth at the given radius is ...

  2π(20,906,000 ft) ≈ 131,356,272 ft

If that circumference represents 360°, as it does for latitude, then we can find the length of an arc-second by dividing by the number of arc-seconds in 360°. That number is ...

  (360°/circle)×(60 min/°)×(60 sec/min) = 1,296,000 sec/circle

Then one arc-second is

  (131,356,272 ft/circle)/(1,296,000 sec/circle) = 101.355 ft/arc-second

__

Each degree of latitude has the same spacing as every other degree of latitude everywhere. So, this distance is the length of one arc-second of latitude: 101.355 ft.

_____

<em>Comment on these distance measures</em>

We consider the Earth to have a spherical shape for this problem. It is worth noting that the measure of one degree of latitude is almost exactly 1 nautical mile--an easy relationship to remember.
