PHYSICS The force of gravity between two objects is inversely proportional to the square of the distance between them. The distance from the Moon to Earth is between 357,000 km and 407,000 km. How many times greater is the force of Earth's gravity on the Moon at its closest
distance than at its farthest? Round to the nearest tenth.

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?
