Step-by-step explanation:
The number of permutation of n things in which 'a' things are like , 'b' things are like and so on.. is given by :-

Given : A shipping company devises a messaging consisting of 9 flags hung in a line.
Then, the number of different possible messages constructed from a set of 4 white, 3 red, and 2 blue flags will be :-

Hence, the number of different possible messages constructed from a set of 4 white, 3 red, and 2 blue flags= 1260
Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.
natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.
integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.
rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.
irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.
so your answer is integer and rational, hope this helped! :)

Answer:
=3
Step-by-step explanation:
following the order of operations, whatever is in the parentheses gets done first. so you would add 13 + 2 and get 15. then you would subtract 9-4 and get 5. then you would divide the numbers that you got and get 3.
Answer:
x = 9
Step-by-step explanation:
Given y varies directly as y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition y = 6 when x = 27
27 = 6k ( divide both sides by 6 )
4.5 = k
x = 4.5y ← equation of variation
When y = 2 , then
x = 4.5 × 2 = 9
