The Transylvania hypothesis claims that the full moon has an effect on health-related behavior. A study investigating this effect found a significant relationship between the phase of the moon and the (x-4) + 100 where y is the number of consultations as a percentage of the daily mean and x is the days since the last full 15.12 number of general practice consultations nationwide, given by y = 1.9 cos moon. a. What is the period of this function? What is the significance of this period? The period is days. (Round to two decimal places as needed.) Choose the correct meaning of the period p in the context of the problem. The x-distance between the maximum and the minimum of the graph is p. Every p days there is a full moon. There were p% more consultations when there was a full moon. The average number of daily consultations is p. b. If there was a full moon on April 7, on what day in April does this formula predict the maximum number of consultations? What percent increase would be…
d. Predict the amount of new solar power that will be installed in 2013. Do you have much faith in your prediction? Explain, Round to the nearest tenth as needed.) O A. It is predicted that megawatts of new solar power will be installed in 2013. Since the model fits the data points, it is reasonable to assume that this value will be relatively accurate. OB. It is predicted that relatively accurate. megawatts of new solar power will be installed in 2018. Since 2013 is inside the domain of the given data, it is reasonable to assume that this value will be OC. It is predicted that megawatts of new solar power will be installed in 2013. Since the model does not fit the data points, there should be little or no faith placed in the accuracy of this value. OD It is predicted that megawatts of new solar power wvill be installed in 2013, Since 2013 is outside the doman of the given data, there should be ittle or no faith placed in the accuracy of this value.
