Answer:
Step-by-step explanation:
A tree diagram is an elegant way of determining an exhaustive list of sample elements in the sample space. It is by finding the ordered n-tuples of the elements in the events under consideration.
The tree diagram for selecting a person from the population in the given question can be found in the attached image below.
Answer:
Cut it in half so that the two pieces are each 7 in by 4 in.
Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or
Also, note that the angle (4x - 7) and are vertical angles, which means that they are equal to each other. Therefore,
Answer:
a)
b)
c)
d)
And we can find this probability with this formula from the Bayes theorem:
Step-by-step explanation:
For this case we assume that the random variable X follows this distribution:
Part a
The probability density function is given by the following expression:
Part b
We want this probability:
And we can use the cumulative distribution function given by:
And replacing we got:
Part c
We want this probability:
And we can use the CDF again and we have:
Part d
We want this conditional probabilty:
And we can find this probability with this formula from the Bayes theorem:
