Model 2: Another plan to secure the roller coaster involves using a cable and strut. Using the center of
the half-circle as the origin, the concrete strut can be modeled by the equation y= 2x+8 and the
mathematical model for the cable is y=x-8. The cable and the strut will intersect
6. Graph the cable and the strut on the model of the roller coaster using the graphing calculator.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
