Answer:
-If the legs of the triangle added up are bigger than the hypotenuse, its an acute tri.
-if they are smaller then its and obtuse angel
-if the legs added up are = to the hypotenuse, then the triangle Is a right triangle.
your right triangle is:
5,12,13
Step-by-step explanation:
Because 5^2+12^2=13^2
It is true
Answer:
a) .3607.
b) See explanation below.
Step-by-step explanation:
The probability that the flight of the airline arrives on time is .775. The problem tells us that the events are independent and asks us what is the probability that 4 flights arrive on time.
Since the probability is independent we can simply multiply the probabilities of each flight arriving on time.
Probability that all 4 flights arrive on time = (.775)(.775)(.775)(.775) = 0.3607.
b) How realistic it is to assume that the on-time arrivals are independent?
This assumption is not very realistic, considering that if one flight is not on time, it will obviously affect all the other flights since the planes are constantly connected to each other and if the flights are using one same plane, the fact that this plane is not on-time will affect the next flight.
