Given:
The path the dolphin Travels can be modelled by where h represents the height of the dolphin and d represents horizontal distance.
To find: maximum height that the dolphin reaches and the distance covered by dolphin
Solution:
Differentiate with respect to
To find the critical point, put
Differentiate again with respect to
So, is a point of maxima

Answer:
214.5 seconds or less time will qualify individuals for such training
Step-by-step explanation:
given that the time that it takes a randomly selected job applicant to perform a certain task has a distribution that can be approximated by a normal distribution with a mean value of 150 sec and a standard deviation of 25 sec.
i.e. X the time that it takes a randomly selected job applicant to perform a certain task is N(150,25)
The fastest 10% are the ones who are above the 90th percentile
We know 90th percentile for Z std normal score is 1.28
Corresponding X score would be
Round off to one decimal
214.5 seconds or less time will qualify individuals for such training
