11.18 is greater than 11 and less than 13
Answer:
-6 - square root 31, -6 + square root 31
Just multiply the with and the length by four (considering the scale factor is 4)
3x4=12 and 7x4=28
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:
