The two scalene triangles seen below are similar figures. What is the scale factor from the small scalene triangle on the left to the large scalene triangle on the right? The scalene triangles are not drawn to scale.

What is the equation of a line passing through (-6,5) and having a slope of 1/3

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

True or false? the sum of the differences (% - 7) is never zero for any distribution consisting of n observations.
