Problem 1

Square A is smaller than Square B. Square B is smaller than Square C.

The three squares’ side lengths are \(\sqrt{26}\), 4.2, and \(\sqrt{11}\).

There are 3 differently sized squares labeled, from left to right, “A,” “B” and “C.” The squares are arranged from smallest to largest, so that “A” is the smallest square and “C” is the largest.

What is the side length of Square A? Square B ? Square C? Explain how you know.

ForLesson 4: Fitting a Line to Data

The scatter plot shows the heights (in inches) and three-point percentages for different basketball players last season.

Circle any data points that appear to be outliers.
Compare any outliers to the values predicted by the model.

Scatter plot with line of best fit drawn. Horizontal axis, height in inches, scale 70 to 90, by 5’s. Vertical axis, 3 point percentage, scale 0 to 60, by 15’s.
