urism in the 1990s Suppose the following table gives the number of people (in thousands) who visited Australia and South Africa in 1998. From To From North America Europe Asia To North America Europe Australia Asia 450 960 1,800 eferring to the 1998 tourism figures, assume that the following (fictitious) figures represent the corresponding numbers from 1988. 490 South Africa 890 200 1,380 960 Australia South Africa 190 110 810 40 Take A to be the 3 x 2 matrix whose entries are the 1998 tourism figures and take B to be the 3 x 2 matrix whose entries are the 1988 tourism figures. (a) Compute the matrix A - B. 11 What does this matrix represent? O It represents changes in number of visitors in 1998. It represents changes in number of visitors over the period 1988-1998. O It represents changes in number of visitors over the period 1998-2008. O It represents changes in number of visitors in 1988. (b) Assuming that the changes in tourism over 1988-1998 are repeated in 1998-2008, give a formula (in terms of A and B) that predicts the number of visitors from the three rec
