* Question Completion Status: The link above provides a list of ten symbolically written statements which are numbered 1-10. Each of the statements matches one blank space in the text below. Fill each of the blanks with the number of the matching statement. Let X be the universal set for variables x and y, and let P(x) be an open sentence. Let T be a nonempty set such that for each t in T, there is a corresponding set At. The set is called the truth set of P(x). is a symbolic form of the statement saying that for some x in X, P(x). is a symbolic form of the statement saying that for every x in X, P(x). The statement saying that "for some x in X, P(x)" is true if The statement saying that "for every x in X, P(x)" is true if x is an element of the union of the sets At provided that x is an element of the intersection of the sets provided that The sets in the family {At} are pairwise disjoint provided that The negation of "for some x in X, for every y in X, P(x) implies P(y)" is The…

Could you write a formal proof for the following: For all sets A, B, and C, if A ⊆ B and B ∩ C = ∅ then A ∩ C = ∅.
A certain radioactive substance has a half-life of 3.6 years. Find how long it takes (in years) for the substance to decompose to 10% of its initial amount.
Consider the following statement. Assume that all sets are subsets of a universal set U. For all sets A and B, if A C B then B C A°. Use an element argument to construct a proof for the statement by putting selected sentences from the following scrambled list in the correct order. Therefore, by definition of complement x E A, and thus, by definition of subset, B CA. Hence, x € A, because A NB = 0. By definition of complement, x € B. Suppose A and B are any sets such that AC B, and suppose x E B. If x were in A, then x would have to be in B by definition of subset. But x B, and so x A. Suppose A and B are any sets such that A C B, and suppose x E B. Proof: 1. .--Select--- 2.---Select--- 3. --Select--- 4. |--Select---
