Robin’s scores: 99, 108, 102, 107, 119
Mean = 107; MAD = 5.2
Evelyn’s scores: 125, 137, 138, 145, 145
Mean = 138; MAD = 5.6
Explain what the mean absolute deviation is in general. Explain what the MAD means in the context of Robin and Evelyn’s data.

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

Find the area of the regular hexagon if a side is 20 cm.

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.
