<h2>Answer:</h2><h2>The angle of depression from the hiker to his car, Θ = 56.39 degrees</h2>
Step-by-step explanation:
A hiker at the top of a mountain spots his car back in the parking lot at the
bottom of the trail. If the trail is 632 meters long and the mountain is 420
meters tall,
opposite side = 632 m
adjacent side = 420 m
Angle of depression, Θ = arctan
= arctan
Θ = 56.39 degrees
Solution: We are given:
We know that a usual values of the test scores falls within 2 standard deviation from the mean.
Therefore, the minimum usual test score is:
The maximum usual test score is:
Therefore, the minimum and maximum “usual” values of the test scores are:
65.4 and 90.6
