Question 19 of 22 © Macmillan Learning An owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree-days, where a day's degree-days are the number of degrees its average temperature falls below 65°F) over a 23-month period. He then computed the least-squares regression line for predicting y from x and found it to be $y' = 85 + 16x$. How much, on average, does gas used increase for each additional degree-day? O 85 cubic feet O 23 cubic feet O 16 cubic feet

11:21 QUESTION 16 During the cardiac cycle, A. The volume of blood leaving the left side of the heart is greater than that leaving the right side B. The pressure of blood leaving the left side of the heart is greater than that leaving the right side C. The duration of systole is greater than that of diastole D. The duration of diastole is greater than that of systole E B and D QUESTION 17 Which of the following is true about the absolute refractory period of cardiac muscle cells? A. It lasts almost as long as the period of contraction B. It is much longer than the absolute refractory period of skeletal muscle cells C. It allows for a single heart-wide contraction to occur that assures smooth ejection of blood from the ventricles D.A and B E.
