The state of Ohio conducted [virus] tests on 107,109 people and 14,581 tested positive.

A: What is p ((with a caret)) for the number who tested positive (round to the nearest hundredth of a percent)?

B: Based upon the testing results of the 11.69 million people who live in Ohio, what is the best estimate for the number of people who would test positive for the [virus]?

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?
