QuestionPoints: 0.5 of 1 Save The population of a certain country was approximately 25 million in 1900,150 million in 1950, and 300 million in 2000 . Construct a model for this data by finding a quadratic equation whose graph passes through the points (0,25),(50,150)(0,25),(50,150), and (100,300)(100,300). Use this model to estimate the population in 2050.
Let xx be the number of years since 1900 and yy be the population in millions. Determine a quadratic equation whose graph passes through the points (0,25),(50,150)(0,25),(50,150), and (100,300)(100,300) \square (Use integers or decimals for any numbers in the expression.)

Studdy Solution
Calculate the value of yy.
y=0.005(22500)+2.25(150)+25 y = 0.005(22500) + 2.25(150) + 25 y=112.5+337.5+25 y = 112.5 + 337.5 + 25 y=475 y = 475
Solution: The estimated population in 2050 is 475475 million.
