Can Someone help with the answer please. 4. (b) A system has a transfer function H (s)% 3D s + 3 Set æ (t) = te-t and determine the corresponding output signal, y (t), by calculating i. L-1 {H (s) X (s)} from table and partial fraction division, ii. the folding integral / h (t - 7) x (7) dr, where h (t) is the system's impulse response.

Which of the following statements is not true? a. parallel lines are lines in the same plane that never intersect. b. congruent figures have the same shape and same size angles and sides. c. similar figures must have the same shape and the same size. d. a rotation is when you turn a figure around a certain point.

When turned about its axis of rotation, which shape could have created this three-dimensional object?

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.
