The knitting club sold `40` scarves and hats at a winter festival and made `\$700` from the sales. They charged `\$18` for each scarf and `\$14` for each hat. If `s` represents the number of scarves sold and `h` represents the number of hats sold, which system of equations represents the constraints in this situation?

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
