Ascientist is studying the effects of growing human populations on the biodiversity that can be found in a region. each region selected had a different population density of humans from 1 to 10 million per 10 square miles. then in each region the number of different species that can be found was recorded. what type of variable is the dependent variable in this experiment? a. ordered b. categoric c. none of these. d. discrete what industry was created when people suddenly had more time and money available? a. the communications industry b. the internet industry c. the labor industry d. the entertainment industry

Answer 1) Option D : Discrete

Explanation : As in the example the scientist studies about the effects of growing human populations on the biodiversity which is found in a region, and where each region was selected had a different population density of humans from 1 to 10 million per 10 square miles. Then in each region the number of different species that can be found was recorded. So here the numerical data was collected for different regions. So, we can conclude it as discrete because when the variable takes on a countable number of values it is called as discrete.

Answer 2) Option D : The entertainment industry

Explanation : When people had enough time and money with them there was no need of creating the communications industry as it was a need not a luxurious thing. With the creation of Internet industry it is somewhat irrelevant. They had enough of time and money so building a labor industry seems to be a lame choice. So, the option of entertainment industry suits the best.
