The following are weights (in pounds) for a sample of 11 baby girls at the age of 16 months:
20.6 21.2 22.5 23.4 24.6 25.9 26.5 27.3 28.1 29.7
30.8
the estimate for the 70th percentile for these sample data is
pounds. (hint: it may to create a cumulative
frequency table-with the list of actual scores in the "x" column-and include a column of cumulative percentages. to
calculate the percentile, you may need to interpolate between two cumulative percentages, keeping the upper real limits in
mind.)
in the sample data, out of 11 observations are less than or equal to the 70th percentile, and
observations are greater than or equal to this value.
out of 11

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function

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?
