Using the normal distribution, it is found that:

a) The pilot is at the 72th percentile.

b) 19.13% of pilots are unable to fly.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation are given, respectively, by:

\mu = 72.6, \sigma = 2.7.

Item a:

The percentile is the <u>p-value of Z when X = 74.2</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{74.2 - 72.6}{2.7}

Z = 0.59

Z = 0.59 has a p-value of 0.7224.

72th percentile.

Item b:

The proportion that is able to fly is the <u>p-value of Z when X = 78 subtracted by the p-value of Z when X = 70</u>, hence:

X = 78:

Z = \frac{X - \mu}{\sigma}

Z = \frac{78 - 72.6}{2.7}

Z = 2

Z = 2 has a p-value of 0.9772.

X = 70:

Z = \frac{X - \mu}{\sigma}

Z = \frac{70 - 72.6}{2.7}

Z = -0.96

Z = -0.96 has a p-value of 0.1685.

0.9772 - 0.1685 = 0.8087 = 80.87%.

Hence the percentage that is unable to fly is:

100 - 80.87 = 19.13%.

An ice cream cone is filled with vanilla and chocolate ice cream at a ratio of 2:3. If the diameter of the cone is 2 inches and
Tpy6a [65]
Volume of the cone is ⅓πr²h where r= radius=1 in and h=5 in, so volume is 5π/3 cu in. Divide this into 5 equal parts, one part=π/3, so chocolate is 3 parts=π cu in=3.1 cu in = 3.1 cu in approx, answer C.

Need help on solving problems with comon tangents
Orlov [11]

First, find angle ECD using tan^-1(6/4), we get angle as 56.31

Now by proportionate, angle ECD and angle EBA are equal.

Hence you can use tan to find AB i.e, AB = 18/tan(56.31)= 12

Therefore, AB = 12
