A∆B choose the correct answer.​

c {b,d,f} because the common between A and B is b,d,f

Hey Doraemon!

Here's your answer

Step-by-step explanation:

A∆B which is called the symmetric difference between A and B is defined as (A-B)U(B-A).

Now, A-B is the set of all elements which are in A but not

in B. So, A - B = {a,c,e}.

Similarly, B-A is the set of all elements which are in B but not in A. So, B - A = {g,h}.

Hence A ∆ B = (A-B)U(B-A) = {a,c,e,g,h}

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
