Answer:
Step-by-step explanation:
It has been established that the count of drivers traveling between a specific origin and destination in a certain time frame follows a Poisson distribution with a mean μ = 20 (as indicated in the article "Dynamic Ride Sharing: Theory and Practice"†).
a)
b)
c)
d) 2 standard deviations = 2(20) = 40
Thus, this means the range for 2 standard deviations is
20-40, 20+40
which equates to (0,60)
Answer:
35.7 km and 248.3 °
Step-by-step explanation:
To clarify, I will include a diagram as an image.
We begin with the cosine law formula:
y² = 42² + 28² - (2 * 42 * 25 * cos 58 °)
y² = 2389 - 1112.83 = 1276.17
y = √1276.17
y = 35.72 km
Next, to find the bearing of the surveyor from her camp, we apply the sine law:
[(Sin 58 °) / y] = [(Sin A) / 42]
Here, A = (42 * sin 58 °) / 35.72
A = sin⁻¹ (0.9971)
A = 85.7 °
The bearing from the base camp now calculates to: 270 ° - (85.7 ° - 64 °) = 248.3 °
