The arm span and foot length were measured(in centimeters) for each of the 19 students in a statistics class and displayed in the scatter plot. An analysis was completed and the computer output is shown . Using the computer output, what is the correlation ?

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
