If the results of the survey were claimed to indicate that 7.7% of adults in this country who own digital cameras plan to replace their camera in the next 12 months would you say this statement is descriptive or inferential

inferential

Step-by-step explanation: inferential statistics help us to make predictions ( that is, inferences) from that data. With inferential statistics, you take data from samples and make generalizations about a population.

Also, inferential statistics allow us to reach conclusions that extend beyond the immediate data alone

In this question, the survey reports on a sample of the country's population that make an inference to the population. It is therefore an inference statement.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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.
