the scatter plot shows the trade-in value and private-party value of 10 cars. the equation for the regression line is = 1.1x + 1.37. based on the equation, which statement is true?

a. for each increase of $1000 in private-party value, the trade-in value increases by $1100.

b. for each increase of $1000 in private-party value, the trade-in value increases by $1037.

c. for each increase of $1000 in trade-in value, the private-party value increases by $1100.

d. for each increase of $1000 in trade-in value, the private-party value increases by $1037.

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
