You are a plumber installing a pipe. The ratio of the outside diameter to the inside diameter is 1.5 to 1. You use a pipe with a 0.5-inch inside diameter. What is the smallest diameter that you will need to drill to allow the pipe to pass through a wall?

step-by-step explanation:

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.

2+2 obliviously is 4.

the correct answer would be the third option
