Four galaxies with their distances in light-years and velocities in miles per second are listed in the table. Complete the parts (a)-(c). Velocity Galaxy Galaxy I Galaxy II Galaxy III Galaxy IV Distance 50 990 650 9,300 16,000 25,000 950 1700 (a) Let x be distance and y velocity. Plot the points in [- 100, 1800,100] by [- 1000, 28000, 1000]. Choose the correct graph below. А. OB. Q (b) Find the least-squares regression line. The least-squares regression line is y =x+ (Round to three decimal places as needed.) (c) If Galaxy V is receding at a speed of 36,500 miles per second, estimate its distance. If Galaxy V is receding at a speed of 36,500 miles per second, then its distance is about light-years. (Round to the nearest integer as needed.)
