True or false: The mapping notation for reflecting point (x, y) about the x-axis is (−x, y).(1 point) This statement is false. The mapping notation for reflecting point (x, y) about the x-axis is (−x,−y). This statement is false. The mapping notation for reflecting point (x, y) about the x-axis is (x,−y). This statement is true. This statement is false. The mapping notation for reflecting point (x, y) about the x-axis is (y, x).

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.
