Are the expressions equivalent? Use j = 3 and j = 8 to determine if they are. 7(j – 2) 4j – 5

No, because when j = 8, the values of the expressions are different.
Yes, because when j = 3, the value of both expressions is 7 and when j = 8, the value of both expressions is 42.
Yes, because when j = 3, the value of both expressions is 7.
Yes, because when j = 8, the values of the expressions are different.

30 points to anyone who gives me the answer pls I NEED HELP

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.
