Time sensitive. what are the solutions to the system of equations? {y=x2−3x−y=1 solve the system by graphing. a. (0, −3) and (0, −1) b. (1, −2) and (−2, 1) c. (2, 1) and (−1, −2) d. (1, 2) and (−2, −1)

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.
