Triangle PQR has coordinates P(–8, 3), Q(–8, 6), and R(–3, 6). If the triangle is translated by using the rule (x, y) right-arrow (x + 4, y minus 6), what are the coordinates of triangle P prime Q prime R prime? (a)P prime (negative 12, 9), Q prime (negative 12, 12), R prime (negative 7, 12) (b)P prime (negative 4, 7), Q prime (negative 14, 0), R prime (1, 10) (c)P prime (negative 4, 9), Q prime (negative 4, 12), R prime (1, 12) (d)P prime (negative 4, negative 3), Q prime (negative 4, 0), R prime (1, 0)

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.

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
