Ms. harris is stocking up on dry-erase markers for the upcoming school year. she used 56 dry-erase markers last year and plans to use at least that many for next year. the number of markers in each box is two more than three times the number of boxes she purchased for this upcoming school year. which of the following inequalities can be used to determine b, the number of boxes she purchased. a. 3b2 - 2b ≤ 56 b. 2b2 - 3b ≤ 56 c. 2b2 + 3b ≥ 56 d. 3b2 + 2b ≥ 56

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.
