Xavier claims that the number of text messages he sends is proportional to the amount he owes on his monthly phone bill. He has listed the number of text messages sent and the amount he owed for a few months:
January: 300 text messages sent: $15.00 owed
February: 314 text messages sent; $15.70 owed
March: 486 text messages sent; $24.30 owed
April: 205 text messages sent; $10.25 owed
Which of the following methods would help Xavier prove his claim?
Xavier could create a table listing the number of text messages sent in each of the months listed and the name of the month to prove that equivalent
ratios exist
о
Xavier could plot data points based on the number of text messages sent in January, February, and March and the amount he owed for those months
to create a straight line on the graph
Xavier could create equations based on the data collected to prove that as the number of text messages increases the amount owed also increases
Xavier could divide the amount he owed in April by the number of text messages sent in April to find out how much oach text message costs

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
