A paperweight is thrown straight up with an initial upward velocity of 60 meters per second, and an initial height of 6 meters. The acceleration (due to
gravity) of the object is given by a(t) = - 9.8 meters per second per second,
where tis in seconds. The maximum height of the paperweight is:

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
