Wildlife biologists monitor the ecological health of animals. For large animals whose habitat is hard to access, such as the Rocky Mountain elk, this can be a problem. Is it possible to reliably estimate the weight of an elk using the elk's chest girth? Here is a scatterplot showing x = chest girth (cm) and y = weight (kg) for 19 randomly selected Rocky Mountain elk, along with additional computer output for a least-squares regression line. The mean weight for these elk is 231 kg. (Context and data from Statistics, Learning from Data.)

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

Which is greater, 7 p 5 or 7 c 5? 7p5 7c5

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?
