A music shop is promoting a sale in which the purchaser of a compact disk can roll a die, then deduct a dollar from the retail price for each dot that shows on the rolled die. It is equally likely that the die will come up any integer from 1 through 6. The owner of the music shop pays $5.00 for each compact disk, then prices them at $9.00. During this special promotion, what will be the shop’s average profit per compact disk sold?

- Calculate (y)' 22y + 23° 11y 89°The diversity index, from 0 to 100, measures the chance that two randomly selected people are a different race or ethnicity. The diversity index in the United States varies widely from region to region, from as high as 81 in Hawaii to as low as 11 in Vermont. The bar graph shows the national diversity index for the United States for four years in the period from 1980 through 2010.The data in the graph can be modeled by the formulaD = 0.005x2 + 0.55x + 34,where D is the national diversity index in the United States x years after 1980. According to the formula, what was the U.S. diversity index in 2010? How does this compare with the index displayed by the bar graph?An industrial engineer designed a workstation where the seeing task was difficult because of the size of the components going into the assembly.
