Ahemisphere-shaped dome of radius 30 ft is to be coated with a layer of rust-proofer before painting. use differentials to estimate the amount of rust-proofer needed if the coat is to be 0.01 in. thick. (round your answer to two decimal places.) hint: the volume of a hemisphere of radius r is v = 2 3 πr3.

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
