A squirrel is 54 feet up in a tree and tosses a nut out of the tree with an initial velocity of 18 feet per second. The nuts height, h, at time t seconds can be represented by the equation h(t)= -16t^2 +18t +54. If the squirrel climbs down the tree in 3 seconds, does it reach the ground before the nut?

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
