Consider the following two assertions about x. Assume x is a specific but unknown real number.

a. x< 2 or it is false that 1 <x< 3.

b. x≤ 1 or either x< 2 or x≥ 3.

Define statement letters for each of the individual statements (e.g., “x< 2” is a statement).

If the same statement occurs more than once, use the same statement letter for all occurrences.

Using those statement letters, rewrite assertions a and b as two logical expressions. Then construct a truth table to show that a and b are logically equivalent.

Consider the following (true) statement: “All birds have wings but some birds cannot fly.” Part 1 Write this statement symbolically as a conjunction of two sub-statements, one of which is a conditional and the other is the negation of a conditional. Use three components (p, q, and r) and explicitly state what these components correspond to in the original statement. Hint: Any statement in the form "some X cannot Y" can be rewritten equivalently as “not all X can Y,”...

3.   Consider the following data set for an office structure built by Anderson Construction Co. The completed building is nine stories. However, construction was interrupted by a fire after 5.3357 floors were completed. At the time of the fire, Anderson had used 54,067 hours of labor to construct the first 5.3357 stories of the building. It then took Anderson an additional 40,750 labor hours to complete this nine-story building. In this problem, FLRCOM is the number of floors completed, and...
