A) an = 3an-1 B) an = 2an-1 + 2 C) an = 4an-1 - 2 D) an = 3an-1 - 4 8) A) Which scenario is an example of using sampling? Juwon is conducting a study to determine how many vegetarians are in her high school English class. To complete the study, she surveys all of the students in the class. B) Kyla is conducting an experiment to determine popular music choices for the students in her school. To complete her experiment she randomly selects participants from each homeroom. C) Kevin is conducting an experiment to determine how many students at his school work a part time job. He surveys every student at his high school by sending out surveys to the homeroom teachers. D) Marques is conducting an experiment to determine how many students play in the high school band and also play sports. While conducting the study he surveys every member of the high school band. 9) If an angle has a measure of 120°, then it is an obtuse angle. Write the converse of the conditional statement and determine whether it is true or false. A) If an angle is obtuse, then is has a measure of 120°.; TRUE B) If an angle is obtuse, then is has a measure of 120°.; FALSE C) If an angle does not have a measure of 120°, then the angle is not an obtuse angle.; TRUE D) If an angle does not have a measure of 120°, then the angle is not an obtuse angle.; FALSE Simplify the expression. 10) (8 + -3 ) - (5 -3 ) A) B) C) D) 11) 13 - 2i 3 13 + 2i 3 3 - 2i 3 3 + 2i 3 Star Distance Star Distance M 2.8 N 3.5 P 4.9 Q 8.8 The table shows the distances, in trillions of miles, of four stars from the earth.
