You don't need to answer the multiple-choice question. Use the model for W to determine how much of the width of the moon is illuminated 8 days after a full moon.(Give your answer to the nearest whole number.)W =The following observation is taken from the website of the Astronomical Applications Department of the U.S.Naval Observatory:Although Full Moon occurs each month at a specific date and time, the Moon's disk may appear to be full for several nights in arow if it is clear. This is because the percentage of the Moon's disk that appears illuminated changes very slowly around the timeof Full Moon (also around New Moon, but the Moon is not visible at all then).Explain this observation in terms of a graph of the function W and rates of change. Use the graphing utility to plot the graphof W. Let W be the fraction of the width of the moon illuminated (as we observe it) as a function of time i in days. For example, whenthe moon is full, W = 1. One model is12xtW =+-cos29.5This model assumes that i = 0 corresponds to a full moon.This model for W represents a sine wave that has been shifted vertically. State the period of the sine wave.(Give an exact answer. Use symbolic notation and fractions where needed.)period:daysExplain in terms of phases of the moon what this period means.This period represents the number of days between the phase of the new moon and the phase of the half moon.This period represents the number of days between the phase of the new moon and the phase of the full moon.This period represents the number of days it takes the moon to get from any phase to that same phase again.

We have the model, W = 12+12cos2πt29.5 Where t is time in days.

Answered: Let W be the fraction of the width of…

Last year’s freshman class at Big State University totaled 5,320 students. Of those, 1,262 received a merit scholarship to help offset tuition costs their freshman year (although the amount varied per student). The amount a student received was N($3,450, $480). If the cost of full tuition was $4,050 last year, what percentage of students who received a merit scholarship did not receive enough to cover full tuition?

The owner of a golf course wants to determine if his golf course is more difficult than the one his friend owns. He has 26 golfers play a round of 18 holes on his golf course and records their scores. Later that week, he has the same 26 golfers play a round of golf on his friend's course and records their scores again. The average difference in the scores (treated as the scores on his course - the scores on his friend's course) is -1.79 strokes and the standard deviation of the differences is 5.907 strokes. The owner uses this information to calculate the 90% confidence paired t-interval of (-3.769, 0.189). Which statement is the correct interpretation of this interval? Question 10 options: 1) We are 90% confident that the difference between the average score on the owner's golf course and the average score on the friend's golf course is between -3.769 and 0.189. 2) We are certain the average difference in scores between the two…
