Kudrey was making a box plot. He first plotted the least and greatest values. He then divided the distance into half, and then did this again for each half. What did Kudrey do wrong?
He assumes all quartiles
(select)
when, in fact, quartiles
(select)
. His error probably comes from thinking quartiles are based on the
(select)
when they are actually based on the
(select)
.

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.
