Answer:

Average rate of change =250

Step-by-step explanation:

Formula to determine average rate of change of the function,

Average rate of change = $\frac{f(x_2)-f(x_1)}{x_2-x_1}$

Where $x_1$ and $x_2$ are the points representing number of years after year 2000.

Since $x_1$ = 5 and $x_2=19$ ,

$f(x_2)=650$

And $f(x_1)=300$

Now average rate of change = $\frac{650-300}{19-5}$

= $\frac{350}{14}$

= 250

Therefore, average rate of change of the number of influenza cases from 2005 to 2019 is 250.

The figure shows the relationship between the number of miles per gallon on the highway and that in the city for some cars.

Leno4ka [110]

In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:

For each additional city mpg, the highway value goes up by

0.9478 mpg.

And It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.

According to the statement

we have given that the relationship between the number of miles per gallon on the highway in the graphical representation and that in the city for some cars.

And we have to give some reasons for the given statements.

So, For this purpose, we know that the

A. In this statement we have to tell that the what is shown in the given relationship in the graph.

So, For each additional city mpg, the highway value goes up by

0.9478 mpg.

And the second statement is

B. I this we have to tell the intercept of the plane in the given Relationship.

So, It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.

So, In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:

For each additional city mpg, the highway value goes up by

0.9478 mpg.

And It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.
