• # question_answer 1)                 The following graph shows the temperature of a patient in a hospital, recorded every hour. (a) What was the patient's temperature at 1 p.m.? (b) When was the patient's temperature ${{38.5}^{o}}C$? (c) The patient's temperature was the same two times during the period given. What were these two times? (d) What was the temperature at 1.30 p.m.? How did you arrive at your answer? (e) During which periods did the patient's temperature showed an upward trend?

(a) The patient's temperature at 1 d m was ${{36.5}^{o}}C$.                              (6) The patient's temperature was ${{38.5}^{o}}C$ at 12 noon. (c) The two times when the patient's temperature was the same were 1 p.m. and 2 p.m. (d) The temperature at 1.30 p m was ${{36.5}^{o}}C$. The point between 1 p.m. and 2 p.m. on the x-axis is equidistant from the two points showing 1 p.m. and 2 p.m., so it will represent 1.30 p.m. Similarly, the point on the y-axis between ${{36}^{o}}C$ and ${{37}^{o}}C$ will represent ${{36.5}^{o}}C$? (e) The patient's temperature showed an upward trend during the periods 9 a.m. to 10 a.m., 10 a.m. to 11 a.m. and 2 p.m. to 3 p.m.
