The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times. what is the experimental probability of rolling a 1 or a 5? enter your answer as a fraction in simplest form, in the box.

Find the distance between the point (-3,-4), and (see the picture below)

The circle below is centered at the point (3, 1) and has a radius of length 2. what is the equation?

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
