Question

P t = 24.8 1.036 t The function P gives the predicted population, in millions, of a certain country for the period from 1984 to 2018 , where t is the number of years after 1984 . According to the model, what is the best interpretation of the statement &ldquo; P 8 is approximately equal to 32.91 &rdquo;?

Accepted Answer

Choice C is correct. The function P gives the predicted population, in millions, of a certain country for the period from 1984 to 2018 , where t is the number of years after 1984 . Since the value of P 8 is the value of P t when t = 8 , it follows that " P 8 is approximately equal to 32.91 " means that the value of P t is approximately equal to 32.91 when t = 8 . Therefore, the best interpretation of the statement " P 8 is approximately equal to 32.91 " is that 8 years after 1984 , the predicted population of this country was approximately 32.91 million. Choice A is incorrect. In 1984 , the predicted population of this country was 24.8 million, not approximately 8 million. Choice B is incorrect. In 1984 , the predicted population of this country was 24.8 million, not approximately 32.91 million. Choice D is incorrect. 32.91 years after 1984 , the predicted population of this country was 24.8 1.036 32.91 million, or approximately 79.42 million, not approximately 8 million.
