Aschool system is testing a new math teaching strategy for geometry. ten classes were randomly selected to pilot the new strategy, and 10 classes were randomly chosen to continue using the current strategy. at the end of the school year, more than 50% of the data overlapped. consequently, the school system could not make a determination about which teaching strategy produced higher test scores. what can the school system do to make the decision more definitive?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
