Question

there is a positive and non - linear association. there is a linear association. as the value of x increases, the value of y increases. explain: keep trying! as the value of x increases, the value of y cannot be predicted. there is no association. as the value of x increases, the value of y increases. explain: keep trying! there is a linear association. there is a positive association. as the value of x increases, the value of y increases. explain: keep trying!

Explanation:

1. For the first scatter - plot: The points do not lie on a straight - line but seem to follow a non - linear upward trend, so there is a positive and non - linear association. As x increases, y generally increases in a non - linear way.
2. For the second scatter - plot: The points are randomly scattered, so as the value of x increases, the value of y cannot be predicted and there is no association.
3. For the third scatter - plot: The points seem to roughly follow a straight - line pattern with an upward trend, so there is a linear and positive association. As x increases, y increases.

Answer:

1. There is a positive and non - linear association; As the value of x increases, the value of y increases.
2. As the value of x increases, the value of y cannot be predicted; There is no association.
3. There is a linear association; There is a positive association; As the value of x increases, the value of y increases.
