Graph a triangle (abc) and reflect it over the x-axis to create triangle a’b’c’. describe the transformation using words. make sure you refer to the characteristics and the coordinates. draw a line segment from point a to the reflecting line, and then draw a line segment from point a’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristic if you drew the line segment connecting b with the reflecting line and then b’ with the reflecting line? how do you know? ( ! )

The coordinates r(1, -3), s(3, -1) t(5, -7) form what type of polygon? a right triangle an acute triangle an equilateral triangle an obtuse triangle

Azul has 4 green picks and no orange picks. you add orange picks so that there are 2 orange picks for every 1 green pick. how many picks are there now.

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
