The chesapeake bay tides vary between 4 feet and 6 feet. the tide is at its lowest point when time (t) is 0 and completes a full cycle in 12 hours. what is the amplitude, period, and midline of a function that would model this periodic phenomenon?
amplitude = 1 foot; period = 12 hours; midline: y = 5
amplitude = 2 feet; period = 6 hours; midline: y = 1
amplitude = 2 feet; period = 12 hours; midline: y = 5

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).

Which statement is true? n is a point of tangency on circle p. pt is a secant of circle p. is a secant of circle p. vu is a tangent of circle p.
