The iq score and brain volume are listed for each of five different subjects. refer to the table of measurements below. given that the data are matched and considering the units of the data, does it make sense to use the difference between each iq score and brain volume that is in the same column? why or why not? iq score and brain volume subject 1 2 3 4 5 iq score 96 124 115 78 124 brain volume left parenthesis cm cubed right parenthesis 1183 1109 1141 1025 1093 choose the correct answer below.

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?
