Calculate the variance for the data set. round your answer to the nearest hundredth. show all of your steps. { 10 , 19 , 21 , 28 , 12 , 20 , 16 }

Me find the measure to side a and the process to solve the problem you appreciate it : )

Name each raycalculation tip: in ray "ab", a is the endpoint of the ray.
