In a test of military ordnance, a large mumber of bombs were dropped on a target from various heights. The initial velocity of the bombs in the direction of the ground was 0. Let y be the height in meters from which a bomb is dropped, let x be the time in seconds for the bomb to strike the ground, let w = x, and let y= V. The relationship between x and y is given by y = 4.9x. For each of the following pairs of variables, state whether the correlation coefficient is an appropriate summary. a x andy b. w and y C x and v d. wand v e. Inxand Iny
