Craig is investigating how long his phone's battery lasts (in hours) for various brightness levels (on a scale of 0-100). His data is displayed in the table and graph below. Do not round between steps. Round answers to at least 4 decimal places.  Brightness Level (x) 32 40 48 66 71 77 84 95 Hours (y) 5.6 4.2 5 3.9 3.7 1.8 1.6 1.5 1) Find the equation for the line of best fit. Keep at least 4 decimals for each parameter in the equation. y^ (y hat)=    2) What does the equation predict for the number of hours the phone will last at a brightness level of 71?  hours  What is the residual for the point (71,3.7)?  hours 3)  e) Find the 95% prediction interval for the number of hours the phone will last at a brightness level of 71.  < y <  hours

I entered this question before, and it was wrong.  Please help me choose all of the correct statements, as I have no idea how to do this.    Complete the table by computing the absolute and relative change.     Time      Value      Absolute Change    Relative Change  0 10.97 XXXXX XXXXX 1 18.76     2 32.08     3 54.86     4 93.81     5 160.42     (i) Which of the following statements are true? Select all that apply.A. The data suggest that an exponential model would be appropriate.B. The data show a constant growth rate.C. The data suggest that a linear model would be appropriate.D. The data increase by a fixed amount each year.E. No model can be inferred from the data provided. (ii) Use the data from the table to construct the appropriate model to predict the value at future times. What value does your model predict when the time is 6.75?(Express your answer rounded correctly to the nearest hundredth.)

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…
