The final temperature is the sum of the initial temperature and the change in temperature. The initial temperature is 102°F. The change in temperature is -3°F.
Operation:
Tf = Ti + ΔT = 102°F + (-3°F) = (102 - 3)°F = 99°F

Answer:
47 bpm
B
Step-by-step explanation:
Draw a trend line (attached).
Reading from the graph, the resting hear rate, in bpm, of a person who exercises an average of 8 hours a week is approximately 47.
The only scatter plot that suggests a linear relationship between x and y is graph B (see second attachment) as the trend line is a straight line.
