This is my final exam question me so i can pass it

the future population of a small central american country of 23 million people can be modeled by the exponential equation p(t) = p0(e)0.02t, where p(t) is the future population in t years and p0 is the current population in millions of people.

which of the following graphs represents this model, what is the expected population of this country (rounded to the nearest tenth of a million) in 25 years, and how long will it take (rounded to the nearest year) for the current population to reach 30 million?

The weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to ac voltage. the values of the parameters depend on the voltage and temperature; suppose α = 2.5 and β = 190. (a) what is the probability that a specimen's lifetime is at most 250? less than 250? more than 300? (round your answers to four decimal places.) at most 250 less than 250 more than 300 (b) what is the probability that a specimen's lifetime is between 100 and 250? (round your answer to four decimal places.) (c) what value is such that exactly 50% of all specimens have lifetimes exceeding that value? (round your answer to three decimal places.) hr
