Eric traveled to two cities on a single highway. the total distance one way was 200 miles. the distance from his original location to the first city was 40 miles less than the distance from the first city to the second city. suppose that x represents the distance from the original location to the first city and y represents the distance from the first city to the second city. the following system of equations represents the given situation.

x + y = 200 x = y − 40

which pair of coordinates represents the solution (in miles) to this system of equations?

(70, 130)

(80, 120)

(160, 120)

(100, 100)

(140, 60)

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.
