Number and Algebra: A Millennium of World Population GrowthYear 10A Math InvestigationName: Table 1 summarizes world population values from 1000 A.D. to the year 2000. Table 1: World PopulationOver 1000 YearsYear (A.D.)Population (in millions)1000300110031112004051300396140036215004831600562170064017507951800969185012651900165619101750192018601930207019402300195025551960303919703708198044571990528420006080What is the average growth rate of the world?
1.Calculate the average number of people added to the world per year. Record your results in Table 2 (column 2). Change in population Formula: Average = time period2.Each value you calculated above represents the slope (gradient) of the line that connects two consecutive data points. This assumes that growth of the world population is linear (constant) over that time period. Comment on the validity of this assumption made for times periods with durations of 10, 50, or 100 years. 3.Calculate the average growth rate (%) per century using the data in Table 1. Record your results in Table 2 (column 3). New population -old population Formula: Growth Rate = old population x 100%
