a. parameter
b. descriptive statistics
Step-by-step explanation:
The values of the population charactersitics are summarized by certain numerical descriptive measures called parameters.
The observations composing a sample are used to calculate a corresponding numerical descriptive measure called a statistic.
a. The percent of Americans is of a population and therefore it is a parameter not a statistics.
b. Descriptive statistics deals with the collection, summarization and display of data.
Inferential statistics deals with conclusions drawn based on a sample.
This is descriptive statistics because it is displaying of data collected from a population of America.

Explanation:
The notation
means that we add 8 to the x coordinate and add 5 to the y coordinate. This represents a shift of 8 units to the right and a shift of 5 units up.
Point G is located at (3,5). This means x = 3 and y = 5 pair up together.
Using the translation rule, we get the following
Point G at the location (3,5) moves to point G' which is at the location (11,10)
