I just need help with all the questions with red x next to them

Ocean currents are Important In studies of climate change, as well as ecology studies of dispersal of plankton. Drift bottles are used to study ocean currents in the Pacific near Hawall, the Solomon Islands, New Guinea, and other Islands. Let x represent the number of days to recovery of a drift bottle after release and y represent the distance from point of release to point of recovery in km/100. The following data are representative of one study using drift bottles to study ocean currents. x day's y km /100 14.5 1 79 95 19.2 5.7 11.5 35.4 (a) Verify that Ex = 479, Ey = 86.3, Ex?= 62,477, Zy2 = 1996.79, Exy = 11001.7, and r = 0.94255.
