I need help finding the mean, median, mode, and range of 25.2, 45.5, 61.7, and 28.3

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?

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?
