The goat is tied in the four corners of an 14-foot by 7-foot pump house. The rope is 14 feet. The goat is eating the grass, forming a circle The pattern is 3/4 of a circle radius 14 and 1/4 of a circle radius 7.
Getting the area of radius of 14 feet
Area = 3.14 * r^2
Area = 3.14 * 14^2
Area = 615.44 feet^2
Getting the area of radius of 7 feet
Area = 3.14 * r^2
Area = 3.14 * 7^2
Area = 153.86 feet^2
3/4 of 615.44 = 416.58 feet ^2
1/4 of 153.86 = 38.465 feet^2
So the total area is 500.045 feet^2
Answer:
The probability is 0.0144
Step-by-step explanation:
The probability that x people show up follows a binomial distribution, so it is equal to:
Where n is the number of booked people and p is the probability that a person shows up. Then, the probability that x people show up is:
So, the probability that the number of people who show up will exceed the capacity of the plane is:
P(x>73) = P(74) + P(75)
Where P(74) and P(75) are calculated as:
Finally, P(x>73) is:
P(x>73) = 0.0125 + 0.0019 = 0.0144
