Use the data set below to determine measurements of central tendency. (45, 65, 30, 50, 20, 30)

mean = 50, median = 40, no mode
mean = 45, median = 50, mode = 30
mean = 40, median = 37.5, mode = 30

Asphere has a diameter of 10 in. what is the volume of the sphere?

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
