Farren et al. (2004) compared the toughness of human fingernails along a transverse dimension (side to side) with the toughness along a longitudinal direction, with 13 measurements of each. the toughness of fingernails along a transverse direction averaged 3.3 kj/m2, with a standard deviation of 0.53, while the mean toughness along the longitudinal direction was 6.2kj/m2, with a standard deviation of 2.49. assume that the data are from two independent samples of 13 people

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte

Write each improper fraction as a mixed number. 9/4. 8/3. 23/6. 11/2. 17/5. 15/8. 33/10. 29/12.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
