The table below shows the estimated world population in the given years, rounded to the nearest hundred million. Year 1900 1950 1999 2011 Population (Billions) 1.7 2.5 6.0 7.0 1) Use the exponential regression tool on your calculator to find a function of the form P(t) = a(b) that best fits the data, where t is in years after 1900. ROUND a AND b TO SIX DECIMAL PLACES. From the calculator, a = and b = 2) Using the rounded values from part 1, and assuming that the population continues to grow according to this model, then estimate the population in the years 2050 and 2100, along with the rates of growth. ROUND TO ONE DECIMAL PLACE. According to the model, the population in 2050 would be about billion people, and in 2100, it would be about | billion people. According to our model, in 2050, the population would be growing at a rate of about ROUND TO THE NEAREST MILLION. O A. 73,000,000 people per year O B. 149,000,000 people per year O C. 164,000,000 people per year O D. 128,000,000 people per year According to our model, in 2100, the population would be growing at a rate of about ROUND TO THE NEAREST MILLION. O A. 124,000,000 people per year
