B is a proper subset of C If the cardinal number of C is 8 what is the maximum number of elements in B?
If every element of B is contained in C, then B is a subset of C. If every element of B is contained in C and B is not the same as C, then B is a proper subset of C.The cardinal number of a set is the number of elements in the set.In this case, C has 8 elements, so B has at most 7 elements.
How many elements are there in the set of positive integers less than 8?
7 of them.
What are the number sets that contain the square root of 5?
Any set that contains it, for example, the set {1, 4/7, sqrt(5), -99} sqrt(5) is an irrational number which form a subset of real numbers which form a subset of complex numbers which ...
How many Subset are there in 1 2 3 4 5 6 7 8 9?
Well, honey, the number of subsets in a set with 9 elements is given by 2 to the power of 9, which equals 512. So, there are 512 subsets in the set {1, 2, 3, 4, 5, 6, 7, 8, 9}. Don't worry, I double-checked it just for you.
Is 7 a mathematical real number?
