Are being a girl and playing a sport independent events? Why or why not?
O A. Yes, they are independent, because P(girl) 0.49 and P(girl| plays
a sport) -0.44.
O B. No, they are not independent, because P(girl) = 0.49 and
P(girl| plays a sport) = 0.62.
O C. Yes, they are independent, because P(girl) < 0.49 and P(girl|plays
a sport) = 0.62
O D. No, they are not independent, because P(girl) = 0.49 and
P(girl plays a sport) = 0.44.

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?
