Onur is participating in a walkathon fundraiser. Two donors promised to donate money based on the total distance he walks. The money, A A, in dollars, that he receives from the first donor given that he walks d d kilometers is given by the formula A ( d ) = 1 0 d A(d)=10d. The money, B B, in dollars, that he receives from the second donor given that he walks d d kilometers is given by the formula B ( d ) = 2 d + d 2 B(d)=2d+d 2 . Let T T be the total money that Onur raises from those donors by walking d d kilometers in the walkathon. Write a formula for T ( d ) T(d) in terms of A ( d ) A(d) and B ( d ) B(d). T ( d ) = T(d)= Write a formula for T ( d ) T(d) in terms of d d. T ( d ) = T(d)=

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.
