Question

Determine n(D).
In Exercises 79–84, determine whether the pairs of sets are equal, equivalent, both, or neither.


79.
A = {algebra, geometry, trigonometry},
B = {geometry, trigonometry, algebra}



84.
A is the set of states.
B is the set of state capitals

Answer 1

Two sets are equal if and only if they have the same elements. Example
If, F = {20, 60, 80}
And, G= {80, 60, 20}.

Answer 2

Then, F=G, that is both sets are equal.

Answer 3

Two sets are equivalent if they have the same number of elements.
Example
If, A= {2, 4, 6, 8, 10}
And, B= {10, 12, 18, 20, 22}
Then, n(A)= n(B)= 5, that is, sets F and G are equivalent.

Answer 4

so both are equivalent in my

Answer 5

sets that are equal are also equivalent by default ...

Answer 6

The first pair is both equal as they have same elements and also equivalent as they have same number of elements, the second one is equivalent as the number of states and number of capitals will be same

Answer 7

I dont have to writ down the numbers do i or just say that one is both and the other is equivalent

Answer 8

Ya the first is clear by itself, in the second one the set of states and state capitals will have same no. Of sets

Answer 9

so it would be # 79 A and B =both equal as they have same elements and also equivalent as they have same number of elements. # 84 = is equivalent as the number of states and number of capitals will be same. What you think
