At 6am, the temperature was 67 degrees. this was 14 degrees less than the temperature at midnight. the midnight temperature was 12 degrees less than the 6: 00 pm temperature. what was the 6: 00 temperature in degrees?

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.
