The code chunk that lets the analyst create the phone_number column is: unite(customers, "phone_number", area_code, phone_num, sep="-"
<h3>What is a data frame?</h3>
A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.
In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.
<h3>The executable code in R Studio.</h3>
In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:
- unite(customers, "phone_number", area_code, phone_num, sep="-"

Explanation:
The examples of matter are Solid, Liquid and gas. Matter is defined as anything that has mass and can occupy space so if something does not have mass and cannot occupy space, then its not matter.
There are different kinds of angles. The statement that will accurately correct the two-column proof is that the definition of angle on a straight line.
<h3>What is straight angle?
</h3>
- This is an angle whose sides sit in opposite directions from the vertex usually in the same straight line and is said to be equals two right angles.
Two angles are known to be supplementary when their measures if sum up reaches 180 degrees.
Conclusively, Looking at the angle, m∠ZRY = 180°, this is because angle ZRY is a straight angle and it is not a supplementary angle.
Therefore option A is the correct answer (Image attached)
