There are four tanks of water. The amount of water in gallons, A, over time, t in minutes. These functions
work whent> 0 and t < 80.
-Tank A is given by the function A= 200 + 8t
-Tank B starts at 400 gallons and is decreasing at 5
gallons per minute.
1. Which tank started out with more water?

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
