In long-run equilibrium, which of the following is not equal to price for a perfectly competitive firm?

The above figure shows a monopolistically competitive firm. The figure

A) is only a short-run illustration because the firm is making an economic profit. B) could be either a short-run or long-run illustration because monopolistically competitive firms can make an economic profit in the long-run. C) is only a long-run illustration because the firm is making zero economic profit. D) is neither a short- nor a long-run illustration.

Assume the following. In location A yearly temperatures range from -30°F to 100°F and in location B yearly temperatures range from 55°F to 75°F. In both locations the average yearly temperature equals 65°F. We can conclude that

A) temperature in location A has a higher variance. B) temperature in location B has a higher standard deviation. C) temperature in location A has a lower standard deviation. D) temperatures in both locations have the same standard deviation but different variances.
