A balloon is released from the top of a building. The graph shows the height of the balloon over time. What
does the slope and y-intercept reveal about the situation?

1.)The balloon starts at a height of 10 ft and rises at a rate of 0 ft.
2.)The balloon starts at a height of 0 ft and rises at a rate of 10 ft.
3.)The balloon starts at a height of 0 ft and rises at a rate of 100 ft.

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
