True or false A foreign key is a field in one table that refers to the primary key field in another table and indicates how the the tables are related?
True.
How relational operators represented in c plus plus?
The relational operators are == (equal), != (not equal), < (less than), <= (less than or equal to), > (greater than) and >= (greater than or equal to). All relational operators are boolean, returning true or false depending on the l-value relationship with the r-value, with respect to the operator.
What is the result of True AND False OR True?
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
What type of operator can be used to determine whether a specific relationship that exists between two values?
The relational operators: ==, !=, =.p == q; // evaluates true if the value of p and q are equal, false otherwise.p != q; // evaluates true of the value of p and q are not equal, false otherwise.p < q; // evaluates true if the value of p is less than q, false otherwise.p q; // evaluates true if the value of p is greater than q, false otherwise.p >= q; // evaluates true of the value of p is greater than or equal to q, false otherwiseNote that all of these expressions can be expressed logically in terms of the less than operator alone:p == q is the same as NOT (p < q) AND NOT (q < p)p != q is the same as (p < q) OR (q < p)p < q is the same as p < q (obviously)p q is the same as (q < p)p >= q is the same as NOT (p < q)
Is it true or false that a computer cannot disobey programming instructions?

true
The two DNA strands that form during mitosis are identical true or false?
True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
True or false Is hybridization breeders cross two individuals that are genetically identical?
false
True or false Millions of individuals have identical DNA profiles?
False. No one, except identical siblings, have the exact same DNA profiles.
True or FalseParticles in a table that does not move, possess kinetic energy?
False
Is it true or false that isomers have the same physical properties because the chemical formulas are identical?
False
Are Table sugar and table salt are pure substances true or false?
it is not true it is a chemical reaction
What is the truth table for p arrow q?
Not sure I can do a table here but: P True, Q True then P -> Q True P True, Q False then P -> Q False P False, Q True then P -> Q True P False, Q False then P -> Q True It is the same as not(P) OR Q
How do you construct a truth table for parenthesis not p q parenthesis if and only if p?
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
What Every ordered pair in a table of values can come from a different function. True False?
true
Is the following true Table sugar and salt are pure substances false or true?
true
The vertical columns on the periodic table of elements are called periods. true or false?
no its false i put true and it was wrong they are called groups!!!!!
