Answer:
circumcenter
Step-by-step explanation:
Suppose the three food trucks points a,b,c are joined together in such a way that the form a triangle. The perpendicular bisectors of the triangle are concurrent . The point of concurrency is called <u>circumcenter.</u>
According to the circumcenter theorem the points ( vertices of the triangle a,b,c) are equidistant from the center D ( point of concurrency) called the circumcenter.
As the food distributor is equidistant from each of the trucks it lies at the circumcenter point of concurrency.
The drawing is just a generalizations to give an idea. It does not show actual bisectors perpendicular.
Answer:
a) 0.0245 = 2.45%
b) 0.9483 = 94.83%
c) 0.6931 = 69.31%
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they are independent, or they are not. The probability of a person being independent is independent of any other person. 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.
It is believed that 12% of voters are independent.
This means that
Survey of 29 people
This means that
a. what is the probability that none of the people are independent? probability =
This is P(X = 0). So
0.0245 = 2.45% probability that none of the people are independent
b. what is the probability that fewer than 7 are independent? probability =
0.9483 = 94.83% probability that fewer than 7 are independent
c. what is the probability that more than 2 people are independent? probability =
Either two or less are, or at least 3 are independent. The sum of the probabilities of these events is decimal 1. So
We want P(X > 2). So
In which
0.6931 = 69.31% probability that more than 2 people are independent
