Suppose iq scores were obtained for 20 randomly selected sets of twins. the 20 pairs of measurements yield x overbarequals99.23, y overbarequals98.1, requals0.917, p-valueequals0.000, and modifyingabove y with caret equals negative 1.76 plus 1.01 x, where x represents the iq score of the twin born first. find the best predicted value of modifyingabove y with caret given that the twin born first has an iq of 103? use a significance level of 0.05.

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
