The average age of students in a statistics class is 28 years. the 28 years would be considered an example of:

descriptive statistics.

Step-by-step explanation:

28 years which is the mean age of students in the class is an example of descriptive statistics.

Descriptive statistics gives a summary description of a particular data quantitatively.Examples of descriptive statistics includes measure of central tendency(e.g. mean median mode), measure of frequency and measure of position.

step-by-step :

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
