Wei is standing in wavy water and notices the depth of the waves varies in a periodic way that can be

modeled by a trigonometric function. he starts a stopwatch to time the waves.

after 1.1 seconds, and then again every 3 seconds, the water just touches his knees. between peaks, the

water recedes to his ankles. wei's ankles are 12 cm off the ocean floor, and his knees are 55 cm off the

ocean floor.

find the formula of the trigonometric function that models the depth d of the water t seconds after wei

starts the stopwatch. define the function using radians.

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.
