An 8th Grade Class Develops a Linear Model That Predicts

question 119

Multiple Choice

An 8th grade class develops a linear model that predicts the number of cheerios (a small round cereal) that fit on the
circumference of a plate by using the diameter in inches. Their model is chee^rios = 0.56 + 5.11(diameter) .
-The slope of this model is best interpreted in context as…

• A) For every 1 inch of diameter, the circumference holds about 0.56 more cheerios.
• B) For every 1 inch of diameter, the circumference holds about 5.11 more cheerios.
• C) For every 5.11 inches of diameter, the circumference is about 1 cheerio bigger.
• D) It takes 5.11 cheerios to fill a plate's circumference.
• E) A mistake, because π is about 3.14 and that should be the slope.
