1. An eagle flies from. X to y, at a distance of 320km on a bearing N35W. It then changes direction and flies
550km to point z on
bearing of S55W. If it returns
to its starting point X from z.
a, illustrate the information in the diagram.
b,
calculate the;
a total distance covered, correct to 3 significant figures.
bearing of x from Z, correct to the nearest degree.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
