A pattern of dots grows exponentially. The table shows the number of dots at each step of the pattern. step number 0 1 2 3
number of dots 1 5 25 125
Write an equation to represent the relationship between the step number, n, and the number of dots, y.
At one step, there are 9,765,625 dots in the pattern. At what step number will that happen? Explain how you know.

1. there are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. the first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. the line plot shows the differences after 10 rerandomizations. determine whether the difference in the means of the two groups is significant based on the line plot. explain your answer.
