Choose the best definitions of parameter and statistic. a statistic is a variable that describes a sample and a parameter is a variable that describes a population. a parameter is an unknown characteristic of a group and a statistic is a known characteristic of a group. a statistic is a number that describes a population and a parameter is a number that describes a sample. a statistic is a number that describes a sample and a parameter is a number that describes a population. a parameter is a number that describes a population. a statistic is a number that is used to estimate a parameter.

A statistic is a number that describes a sample and a parameter is a number that describes a population.

Step-by-step explanation:

The definition of "statistic" is:

A piece of data from a portion of a population.

The definition of "parameter" is:

A value that tells you something about a population.

Using these definitions, the correct answer to the question is that a statistic is a number that describes a sample and a parameter is a number that describes a population.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
