In 1950, there were 238,681 immigrants admitted to a country. In 2001, the number was 1,042,425. a. Assuming that the change in immigration is linear, write an equation expressing the number of immigrants, y, in terms of t, the number of years after 1900. b. Use your result in part a to predict the number of immigrants admitted to the country in 2014. c. Considering the value of the y-intercept in your answer to part a, discuss the validity of using this equation to model the number of immigrants throughout the entire 20th century. a. A linear equation for the number of immigrants is y= (Type your answer in slope-intercept form. Use integers or decimals for any numbers in the equation. Type an integer or decimal rounded to two decimal places as needed.) b. The number of immigrants admitted to the country in 2014 will be approximately (Round to the nearest whole number as needed.) c. Choose the correct answer below. OA. The y-intercept gives the number of immigrants in 1900. The equation in part a is valid to model the number of immigrants throughout the entire 20th century. OB. The actual model may or may not be linear. More data points would help model the data more accurately. Using just two data points to create a linear model is not valid.
