See the picture attached to better understand the problem
we know that
A quadrilateral is called Cyclic quadrilateral <span>if its all vertices lie on the circle.
</span><span>The opposite angles of a Cyclic - quadrilateral are supplementary
</span>so
∠A+∠C=180°
and
∠B+∠D=180°
therefore
the answer is
<span>C) The sum measure of ∠B and ∠D equals 180°</span>

Answer: The value of P(E∪F) = 0.64.
Step-by-step explanation:
Since we have given that
P(E) = 0.38
P(F) = 0.38
P(E∩F) = 0.12
So, we need to find the P(E∪F).
As we know the formula for the sets.
Hence,the value of P(E∪F) = 0.64.
Answer:
We need to check the conditions in order to use the normal approximation.
The mean is given by:
And the deviation is given by:
So then the correct options for this case are:
The sampling distribution will be approximately normal.
The mean of the sampling distribution will be 16.4%.
The standard deviation of the sampling distribution will be 0.0262.
Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We need to check the conditions in order to use the normal approximation.
The population proportion have the following distribution
The mean is given by:
And the deviation is given by:
So then the correct options for this case are:
The sampling distribution will be approximately normal.
The mean of the sampling distribution will be 16.4%.
The standard deviation of the sampling distribution will be 0.0262.
