The radius of a bulls-eye of the dash board is 8 inches. the radius of each concentric circle (there are 4 labeled a, b,c, d from the inside out) is 14 inches more than the radius of the circle inside it. if a dart lands at a random on the dartboard, the probability that the dart will hit in the area c is what percent?

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1
