Unnithan, houser, and fernhall (2006) were interested in whether playing the game dance dance revolution (ddr) affected the heart rate of overweight and nonoverweight adolescents differently. a group of 22 adolescents, 10 classified as overweight and 12 as not overweight, played ddr for 12 minutes, during which time the researchers measured each participant's heart rate. which statistical test should the researchers use to analyze their data? independent-samples t test dependent-samples t test z test single-sample t test

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
