Answer:
85.33% probability that a Northern Airlines plane will be on time for at least four of its next five flights.
Step-by-step explanation:
For each Northern Airlines flight, there are only two possible outcomes. Either it is on time, or it is not on time. The probability of a flight being on time is independent of other flights. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Northern Airlines has a reputation for being on time 86% of the time.
This means that 
Find the probability that a Northern Airlines plane will be on time for at least four of its next five flights.
In which

The coordinates system is used to map out and locate objects throughout space. In navigation, satellites use GPS signals to determine where you are relative to a grid placed on earth. This grid typically follows longitudinal and latitudinal lines. Space uses this system in a similar way. Engineers and astronomers use grids to determine the location of planets, stars, and other celestial bodies in the universe. Finally, archaeology uses grids to help map out a site that is being dug. As artifacts are recovered, archaeologists record their location on a coordinate grid because it helps them interpret the living conditions or other human behaviors on the site.
Answer:
(-0.5, 0.5)
Step-by-step explanation:
If those two points are endpoints, just use the midpoint formula.
