It is known in a certain country that 20% of mothers use spanking as a method of disciplining their children. 85% of the mothers that spank their children use valium, while 25% of mothers that don’t use spanking use valium. Does this data suggest that valium causes mothers to spank their children? Explain.

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?

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?
