As a prank, Tim decides to steal Nathan's fork at dinner, but so he doesn't get caught, he convinces other people to do it for him. On Monday, he convinces Joe to do it. On Tuesday, he could get either Ambie or John to do it. On Wednesday, he can't convince any of those three people to do it, but there are five other people he could convince to do it. On Thursday, none of those five will do it, nor the first three, but there are four others who are willing. Finally, on Friday, Tim does it himself. How many different combinations of people could Tim involve in the prank?

40

Step-by-step explanation:

On Monday, there is 1 option.

On Tuesday, there are 2 options.

On Wednesday, there are 5 options.

On Thursday, there are 4 options.

On Friday, there is 1 option.

The number of combinations is 1 × 2 × 5 × 4 × 1 = 40.

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.
