Me ! given that n: {1,2,3,5,8,13} and m: {−9,−8,−6,−4,−2,4}, which statements about n and m are true?

there is more than one correct answer. select all correct answers.

the intersection of n and m contains only those elements that are in both n and m.
the intersection of n and m is ϕ.
the intersection of n and m is {−9,−8,−6,−4,−2}.
n∪m=∅
n∩m=∅
(note: i picked "n∪m=∅" and "the intersection of n and m contains only those elements that are in both n and m." and i got 0.17 percent on the question so one of these two that i picked are correct.)

The intersection of N and M contains only those elements that are in both N and M.

The intersection of N and M is ϕ.

N∩M=∅

Step-by-step explanation:

Given

M = { 1, 2, 3, 5, 8, 13}

N = {-9, -8, -6, -4, -2, 4}

Now let us see each statement one by one.

The intersection of N and M contains only those elements that are in both N and M.

The statement is true because by definition intersection of two sets consists of common elements of both sets.

The intersection of N and M is ϕ.

The statement is true. As there is no common element in both sets.

The intersection of N and M is {−9,−8,−6,−4,−2}.

The statement is false because there is not common element in M and N.

N∪M=∅

The statement is false as the union consists of elements of both sets so it can't be empty.

N∩M=∅

True. Because no common element so intersection will be an empty set..

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
