0.034

Step-by-step explanation:

Data:

Let the standard deviation be : $\sigma = 2$

The mean be: $\mu = 6$

Therefore, P (x>4) which is the probability that a person will wait for more than 4 minutes is given by:

$z = \frac{X- \mu }{\sigma }$

= $\frac{4-6}{2} \\= -1$

Therefore,

P(x > 4) = P (z > -1)

= P (z < -1)

From the z-tables, we find 0.034

The exact area of the sector in terms of π is:

24π in²

Step-by-step explanation:

The area of a sector of a circle is given by:

$\pi r^2\times \dfrac{\theta}{2\pi}$

where r is the radius of the circle and $\theta$ is the central angle of the sector

Here r=12 in.

and $\theta$ =60°

Area of sector=

$\pi 12^2\times \dfrac{60}{2\times 180}$

$\pi 12^2\times \dfrac{1}{6}$

$24 \pi in^2$
