Here is a scatter plot that shows lengths and widths of 20 left feet, togetherwith the graph of a model of the relationship between foot length and width.

Here Is A Scatter Plot That Shows Lengths And Widths Of 20 Left Feet Togetherwith The Graph Of A Model Of The Relationship Between Foot Length And Width class=

Sagot :

1. The point which represents the foot with length closest to 29 cm, is the point with x-coordinate equal to 29 approximately and y-coordinate equal to 10.3 approximately. Please enclose that point.

2. The width of the foot is given by the value the y-coordinate for the point with the foot with a length of 29 cm, that is, the width is approximately 10.2 or 10.3 cm.

3. What the model predicts is represented by the line of the graph. You can notice that the value of the line, for x = 29 cm, is approximately 11 cm. Then, the model predicts that for a foot with a length of 29 cm, the width would be 11 cm.
