An airliner carries 100 passengers and has doors with a height of 76 in. Heights of men are normally distributed with a mean of

69.0 in and a standard deviation of 2.8in.
a. If a male passenger is randomly​ selected, find the probability that he can fit through the doorway without bending.
​(Round to four decimal places as​ needed.)

First let us calculate for the z score using the formula:

z = (x – u) / s

where u is the mean height of men = 69 in, x is the height of the door = 76, and s is the standard deviation = 2.8 in

 

z = (76 – 69) / 2.8

z = 2.5

 

From the standard probability table, at z = -2.5 the probability P is:

P = 0.9938 = 99.38%

How long is the arc intersected by a 2pi/3 radian central angle in a circle with radius 7 feet?
VashaNatasha [74]

=\frac{43.96}{3}Formula to find the central angle is,

s= r\theta

Where, s = arc length

r = radius

\theta= central angle in radian.

According to the given problem,

r = 7 and \theta = \frac{2\pi}{3}.

First step is to plug in these values in the above formula. So,

s= 7*\frac{2\pi}{3}

=\frac{14\pi}{3} By simplifying.

=\frac{14*3.14}{3} Since \pi =3.14

=\frac{14*3.14}{3}

s=14.65

Hence, arc length iss 14.65 feet.
