The answer is 2.25h when we do theese equation
95-50=45
45/20=2.25h
The mean to your problem is 87.5
As we already have the model that describes the change of the population in Italy in terms of the years that have elapsed, we only have to replace the conditions that are requested in that equation.
Therefore to find the population of Italy in the year 2000 (t = 10 years) substitute t = 10 in the equation and have:

million people
To find the population of Italy in 2008 (t = 18 years)
substitute t = 18 in the equation and have:

million people
To predict the population in Italy for 2015 and 2020 with this model, we substitute in the equation t = 25 and t = 30
t = 25
million people
t = 30
million people
Answer: There is linear relationship between the number of days that Kyla exercise in the total minutes that she exercises.
The independent variable is 'd' and m is the dependent variable which depends on the number of days she exercise.
The linear equation for the situation is given by

Step-by-step explanation:
Let d be the number of days that Kyla exercises, and let m represent the total numbers of minutes she exercise.
Kyla spends 60 Minutes of each day exercising which is constant .
Then the total numbers of minutes she exercise(m) in d days is given by
which is the linear equation.
The relationship between the number of days that Kyla exercise in the total minutes that she exercises is linear, where d is the independent variable, and m is the dependent variable which depends on the number of days she exercise.
[ad d increases m increases by rate of 60 minutes per day]
The linear equation for the situation is given by
