On a separate sheet of paper, sketch a coordinate plane. then, starting at the origin (0, 0) and using only quadrant i, draw a square with sides 4q units long. in the box provided, write the coordinates for each vertex and the coordinates of the point of intersection of the diagonals.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65

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
