A tank contained 80 liters of water. The function represents the relationship between , time in minutes, and the amount of water in the tank in liters. The equation defines this function. How much water will be in the tank after 13 minutes?
How many minutes will it take until the tank has 5 liters of water?
In this situation, what information can we gain from the inverse of function ?
Find the inverse of function . Be prepared to explain or show your reasoning.
How would the graph of the inverse function of compare to the graph of ? Describe or sketch your prediction.

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.
