For which data set would the mean absolute deviation (MAD) be a good indicator of variation of the data? 0 6. 0 7. 0 9. 0. please help!!!

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
