Of the total number of people on a cruise ship, 1/4 or child passengers. 2/5 of the remaining people were crew. there were 1320 crew on board how many adult passengers were there

Step-by-step explanation:

       Total number of people on the cruise ship was 1320.

of the people were child passengers. Number of child passengers =

of the people were crew. Number of people that were crew =

       Remaining people in the ship constitute the adult passengers.

       Number of adult passengers =

∴ Number of adult passengers = 462

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.
