Part 1: The correct graph is A. 1988 2008 230 350 x y x y graph.
Part 2: To find the equation of the trend line, we can use the formula for the equation of the line: y = mx + b, where m is the slope and b is the y-intercept.
Using the points (1990, 251) and (2002, 325), we can find the slope:
m = (325 - 251) / (2002 - 1990) = 6.17
Now we can substitute one of the points into the equation and solve for b:
251 = 6.17 * 1990 + b
b = 251 - 6.17 * 1990 = -12,020.67
Therefore, the equation of the trend line is y = 6.17x - 12,020.67. The correct answer is B.
Part 3: To estimate the attendance at theme parks in the country in 2005, we can substitute x = 2005 into the equation and solve for y:
y = 6.17 * 2005 - 12,020.67 = 332.33
The estimated attendance in 2005 is 332 million.
