O(n)
O(n log n)
O(n^2)
O(n^3)
ExplanationBig-O notation considers the highest order term, which in this case is n^2.
E
V + E
2E
V^2
ExplanationAccording to the Handshaking Lemma, the sum of the degrees of all vertices in a graph is equal to twice the number of edges.
1/8
3/8
1/2
2/3
ExplanationUsing the binomial distribution: (3 choose 2) * (0.5)^2 * (0.5)^1 = 3 * 0.125 = 0.375 or 3/8.
A is invertible
A is singular (non-invertible)
A must be a zero matrix
The trace of A is 0
ExplanationA square matrix is singular if and only if its determinant is 0, which is equivalent to at least one of its eigenvalues being 0.
NAND
XOR
Implication
Inhibit
ExplanationThe inhibit gate or operation performs a conjunction of one variable and the negation of another (P ∧ ¬Q).
3 elements
6 elements
8 elements
9 elements
ExplanationThe number of elements in the power set of a set with n elements is 2^n. For n=3, 2^3 = 8.
n(n+1)/2
n^2
n(n-1)
n(n+1)(2n+1)/6
ExplanationThis is the standard formula for the sum of the first n positive integers (the triangular number formula).
5
10
25
32
ExplanationThe cardinality of the power set of a set with n elements is 2^n. For n=5, 2^5 = 32.
f'(x) = 0
f'(x) > 0
f'(x) < 0
f'(x) is undefined
ExplanationA strictly increasing function must have a positive slope (derivative) across its domain.
0010
0110
1110
1000
ExplanationXOR returns 1 if bits are different and 0 if they are the same: 1^1=0, 0^1=1, 1^0=1, 0^0=0. So 1010^1100 = 0110.
