Oscar and Maria each wrote an equation that they felt represented the proportional relationship between length in centimeters and length in inches. They each referred to a table that compared centimeters to inches. One entry in the table paired 127 centimeters with 50 inches. Who wrote the correct equation that would relate centimeters to inches? Explain why. Oscar wrote the equation c = 2.54i, and said that the unit rate 2.54 represents centimeters per inch.
Maria wrote the equation c = 0.394i, and said that the unit rate 0.394 represents centimeters per inch.

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
