Suppose we take 53 samples from a population whose mean is 45 with a standard deviation of 4. Describe the shape of the means of the sampling distribution. Do we
need to make any assumptions about that data? Why or why not?

Which statement best describes the polynomial

What are “like terms”? why can we only add like terms?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
