Triangle xyz has vertices x(1,3), y(0,0)

Find the volume of the described solid. the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x. a) 441b) 147c) 864d) 882

What is the correlation coefficient between the variables? round to three decimal places. enter your answer in the box
