-8 is the number in the middle of -18 and 10

25. A) 11.02 × 10¹¹

1.9 * 5.8 = 11.02 and 10³ × 10⁸ = 10¹¹

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
