The positive numbers will out rule the negative number. It's sort of like placing blocks over another set of blocks. :)
Answer:

And then we can use for example the first point
to find the intercept:


So then the linear model for this case should be:

Step-by-step explanation:
For this case we want to find a linear model given by:

Where r = represent the number of readers , t= years after 2000
m = the slope for the model and b the intercept
For this case we can define the following points from the data given:
4 years after 2000
14 years after 2000
We can find the slope with the following formula:

And then we can use for example the first point
to find the intercept:


So then the linear model for this case should be:

Answer:
6.24 is the answer rounded to the nearest hundreth
Answer:
1. Total distance
2. Shortest time taken
Step-by-step explanation:
Since it is a competition the distance will be the same for all participants.
therefore the information need is
1. The total distance of the competition
2. The time taken by each participant to complete the race
The winning speed is the speed is given as the distance covered in the shortest possible time.
hence the winning speed is expressed as
winning speed= distance/short time taken
