Write two expressions for the perimeter of the figure. 18x
16
9x
4x
Note: The figure is not drawn to scale.
(a) Use all four side lengths.
perimeter = 18 + 9 + 9 + 4

What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

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.
