Linear parent function charecteristics
1 answer:
<h2>Answer:</h2>
In mathematics, a parent function is the simplest function of a family of functions preserving the definition or shapes of the entire family. If you are familiar with the basic characteristics of these simple graphs, this will help you to analyze the shapes of more complicated graphs. So the Linear parent function is the identity function:
and these are the characteristics:
- It's a straight line.
- The slope of this line is m = 1
- This line passes through the origin.

<u>Probabilities</u>
When we choose from two different sets to form a new set of n elements, we use the so-called hypergeometric distribution. We'll use an easier and more simple approach by the use of logic.
We have 6 republicans and 4 democrats applying for two positions. Let's call R to a republican member and D to a democrat member. There are three possibilities to choose two people from the two sets: DD, DR, RR. Both republicans, both democrats and one of each. We are asked to compute the probability of both being from the same party, i.e. the probability is
Let's compute P(DD). Both democrats come from the 4 members available and it can be done in different ways.
For P(RR) we proceed in a similar way to get different ways.
The total ways to select both from the same party is
The selection can be done from the whole set of candidates in different ways, so
