REALLY IMPORTANT ONLY ANSWER IF YOU KNOW THANK YOU A cell phone plan costs $200 to start. Then there is a $50 charge each month.

On a separate piece of paper, answer the following and take a picture then upload it:

Part A: Graph the cost of the cell phone plan over a period of two years, using months as the unit of time. Be sure to label your axes and scale them by labeling each gridline with a number.

Part B: Is there a proportional relationship between time and the cost of the cell phone plan? Explain how you know.

Part C: Draw a line parallel to the line you graphed that goes through the point (0, 350). Suppose that this line represents the pricing plan for another company. What is the startup fee and monthly cost for this plan?

In the field of thermodynamics, rankine is the unit used to measure temperature. one can convert temperature from celsius into rankine using the formula , what is the temperature in celsius corresponding to r degrees rankine? a. 9/5(c - 273) b. 9/5(c + 273) c. 5/9( c - 273) d. 5/9( c + 273)

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.
