If t is in years since 1990, one model for the population of the world, p, in billions, is p=40/1+11e^-0.08t

a) what does this model predict for the maximum sustainable population of the world? enter the exact answer.

this model predicts that t is very large, the population is billion.

b) according to this model, when will the earth's population reach 10 billion? 39.9 billion?

round your answer to the nearest year.
the population of the world should be 10 billion in
the population of the world should be 39.9 billion in

Asimple random sample of size nequals14 is drawn from a population that is normally distributed. the sample mean is found to be x overbar equals 70 and the sample standard deviation is found to be sequals13. construct a 90% confidence interval about the population mean

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
