Acoin is tossed and
a six-sided die numbered 1 through
6 is rolled. find the probability of tossing a
head and then rolling a number greater than 4.

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?

What is the radical expression that is equivalent to the expression 27 1 over 5?

Find two numbers if their sum is 91 and the ratio is 6: 7?
