write functions for each of the following transformations using function notation. Choose a different letter to represent each function. For example, you can use art represent rotations. Assume that a positive rotation occurs in the counterclockwise direction. Translate are youa units to the right in the units of reflection across the Y axis reflection across the X axis rotation of 90° counterclockwise about the origin .0 rotation of 180° counterclockwise about the origin .0 rotation 270° counterclockwise about the origin .0

How can the correlation in the scatter plot graph below best be described? positive correlation negative correlation both positive and negative no correlation

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
