Divers in a competition are scored by an international panel of judges. the highest and the lowest scores are dropped. the total of the remaining scores is multiplied by the degree of difficulty of the dive. this product is multiplied by .6 to determine the final score.
a diversr's final score is 77.7 what is the degree of difficulty of a dive?
the scores are 7.5, 8.0, 6.5, 8.5, 7.0, 7.5, 7.0.

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?

The slope of the line whose equation is 3y = 2x - 3 is 2 2/3 3/2
