Answer:
0.3844 = 38.44% probability that two independently surveyed voters would both be Democrats
Step-by-step explanation:
For each voter, there are only two possible outcomes. Either the voter is a Democrat, or he is not. The probability of the voter being a Democrat is independent of other voters. 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.
62% of the voters are Democrats
This means that 
(a) What is the probability that two independently surveyed voters would both be Democrats?
This is P(X = 2) when n = 2. So


0.3844 = 38.44% probability that two independently surveyed voters would both be Democrats
Answer:
1. If it is just a line and it has no end points then it means that it is a line if it has endpoints then it's a line segnment.
2. a suplementary angle is equal to 180 degrees and congruent angels are equal angles. (conruent is just a fancy word for equal.)

Answer:
The coordinate of the vertex of the parabola is (h,k) = (3,20)
Step-by-step explanation:
The given equation of the parabola is 
Now, the General Parabolic Equation is of the form:
, then the vertex is the point (h, k).
Now, to covert the given equation in the standard form:

Using the COMPLETE THE SQUARE METHOD,

or
⇒The general formed equation of the given parabola is

Comparing this with general form, we get
h = 3, k = 20
Hence, the coordinate of the vertex of the parabola is (h,k) = (3,20)
