HELP ASAP Imani was curious if there was a relationship between one hand being longer than the other and one foot
being longer than the other for students at her school. She measured the hands and feet of 100 randomly
selected students. Here is a summary of the data and the results from a chi-square test:
Chi-square test: Longer hand vs. longer foot

Assume that all conditions for inference were met.

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

Which of the following is correct interpretation of the expression -4+13

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?
