a.
Calculate the distance of the parasailor from the boat.
a.

Answer to Problem 31PPS
In Myrtle Beach, parasailor is at 624.49feet from the boat.
Explanation of Solution
Given:
Length of rope = 800ft (Hypotenuse)
Height of parasailor from the water = 500ft (Perpendicular)
Calculations:
A person is attached to a boat by a long rope during parasailing.
Here, we have to find distance of parasailor from the boat.
According to figure, we can calculate missing element by using Pythagoras theorem.
As per Pythagoras theorem, hypotenuse square is equal to sum of square of remaining two sides.
Conclusion:
Therefore, we are able to calculate distance of parasailor from the boat by using Pythagoras theorem.
b.
Calculate length of the parasailing rope.
b.

Answer to Problem 31PPS
Length of parasailing rope is 2500 ft
Explanation of Solution
Given:
Height of parasailor from the water=2000 ft
Distance of parasailor from the boat = 1500 ft
Calculation:
Here, we have to find value of hypotenuse that is length of parasailing rope.
According to figure, we can calculate missing element by using Pythagoras theorem.
As per Pythagoras theorem, hypotenuse square is equal to sum of square of remaining two sides.
Conclusion:
Therefore, we are able to calculate length of parasailing rope using Pythagoras theorem.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
