A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.
b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score
c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.
d. z = -0.15
The percentile equivalent and the area is equal to 0.44.

I've drawn a triangle to represent the journey (see attached.
The angle from Home to Victim to Hospital is:
a =

Using the cos rule, we can solve for the length x:

Using the cos rule, we can solve for angle b:

So the bearing the helicopter has to travel is:
270 - 76.1 =
<u>
193.9 degrees (1 dp)</u>
And the distance it travels is
<u>31.2 km (1 dp)</u>
