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="-"

Because metalloids are semiconductors. The fact that metalloids are brittle/shiny are only physical characteristics and wouldn’t be the reason why a metalloid would be helpful for designing a new computer processor. Amphoteric means that it’s able to react both as a base and as an acid, but since the computer processor has to have something to do with electricity, the second option would be the answer. Semiconductors are also helpful for electrical circuits, so that’s also why is would be best for the new computer processor.
Benjamin Harrison is the answer.
Answer:
Molecules are held together by shared electron pairs, or otherwise known as covalent bonds.
Explanation:
