Missing question: How many executives should be surveyed?
Solution:
Mean = 13 hours
SD = 3 hours
Confidence level = 95%
Mean viewing time within a quarter of an hour = 0.25 = 1.96*3/sqrt (N)
Where N = Sample population
N = {(1.96*3)/0.25}^2 = 553.19 ≈ 554
Therefore, 554 executives should be surveyed to yield such results.

The zip line forms a right triangle with the tree, when elevated
The height of the tree is 35 meters
<h3>How to calculate the height of the tree</h3>
Represent the height of the tree with h.
So, the height h is calculated using the following sine function

Make h the subject
h = 200 * sin(10)
Evaluate the product
h = 35 meters
Hence, the height of the tree is 35 meters
