Question

PLEASE HELP ASAP!! WILL MARK BRAINLIEST!

Answer 1

Part A:

 For this case we have that the relationship between time and radius is linear.
 We observe that for each day that passes, the radius increases two centimeters.
 Therefore, the linear function is:
 y = 2x
 Since the linear function is exact, the correlation coefficient is:
 r = 1
 Answer:
 r = 1

 Part B:

 As the linear function is:
 y = 2x
 So for days 1 and 2 the slope of the graph is:
 m = 2
 It means that the radius increases 2 centimeters per day.
 Answer:
 m = 2

 Part C:

 The data represents a correlation.
 This is because the data follows a linear trend.
 The radius always grows 2 centimeters for each day that passes.
 Answer:
 Correlation.
