![### Question
The model \( a = 0.25t + 29 \) represents the median age \( a \) of females in the United States as a function of time \( t \) (in years since 1970).
a. **Predict the median age of females in 1980 to the nearest tenth.**
1980 is \([ \hspace{30pt} ]\) years after 1970, so \( a = 0.25( [ \hspace{30pt} ] ) + 29 = [ \hspace{30pt} ] \).
b. **Predict the median age of females in 2025 to the nearest tenth.**
2025 is \([ \hspace{30pt} ]\) years after 1970, so \( a = 0.25( [ \hspace{30pt} ] ) + 29 = [ \hspace{30pt} ] \).](https://content.bartleby.com/qna-images/question/4963a1b7-231e-4415-aa15-591e301cddd8/8ae04e2a-da33-4a72-9fbf-0a9fa212fddf/j0iobe9_processed.jpeg)

- 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.
