Answer:

See below

Step-by-step explanation:

Lets assume weight is input and time is output

The function based on the input and output values is close to linear and it is decreasing (graph is attached)

<u>Answers are</u>

b) Numeric value is obtained -0.99 by using the formula attached as picture. It is 'very strong negative relationship'
c) Yes. Because weigh increase causes time to decrease
