Question

**INSTRUCTIONS:** Use natural deduction to derive
the conclusion in each problem.

Use conditional proof or indirect proof as needed:

1. | (x)[(Kx∨Nx)⊃(Ex •∼Rx)] | |

2. | (x)[(Kx∨Sx)⊃(Rx∨Hx)] | / (x)[Kx⊃(Ex • Hx)] |

Answer #1

Use natural deduction to derive the conclusion in each
problem.
Use conditional proof or indirect proof as needed:
1.
(x)(Jx⊃∼Ga)
2.
(∃x)(Jx • Gc)
/ a ≠ c

5) Translate the following argument into symbolic form and then
use natural deduction (first 18 rules of inference) to derive the
conclusion of each argument. Do not use conditional proof or
indirect proof.
The Central Intelligence Agency (CIA) will lose its funding only
if the President thinks that it is wise and the Congress supports
the move. If either Congress supports the move or covert operations
run amok, then the CIA will have political problems. Therefore, if
the CIA will...

1)Translate all the definitions needed to derive the conclusion
into propositional formulas (i.e., premises)
2)Derive your proof for S using natural deduction with the
premises.
S: there exist irrational numbers a and b such that a^b is
rational
A: √2 is rational

A: √2 is rational
B: √2^√2 is rational
C: √2^√2*√2 is rational

Three step problem. For the following arguments, create a proof
of the conclusion, with the given premises.
Part one: Use "conditional proof": P ⊃ Q /∴ P ⊃ (Q ∨ R)
Part two: Use "indirect proof": (A ∨ B) ⊃ (C ⋅ D) /∴ ~D ⊃ ~A
Part three: B ∨ ~(C ∨ D), (A ∨ B) ⊃ C /∴ B ≡ C

For each of the statements below, say what method of proof you
should use to prove them. Then say how the proof starts and how it
ends. Pretend bonus points for filling in the middle.
a. There are no integers x and y such that x is a prime greater
than 5 and x = 6y + 3.
b. For all integers n , if n is a multiple of 3, then n can be
written as the sum of...

Instructions: Answer the following questions. Each answer or
conclusion must be supported by appropriate references to the FASB
Codification, by using correctly formatted citations. Do NOT copy
and paste the codification sections. Writing counts. Your work must
be organized and logical, using properly structured paragraphs and
sentences, correct grammar and without spelling errors. It is
important to consider who is your audience.

Important Instructions: (1) λ is typed as lambda. (2) Use
hyperbolic trig functions cosh(x) and sinh(x) instead of ex and
e−x. (3) Write the functions alphabetically, so that if the
solutions involve cos and sin, your answer would be
Acos(x)+Bsin(x). (4) For polynomials use arbitrary constants in
alphabetical order starting with highest power of x, for example,
Ax2+Bx. (5) Write differential equations with leading term
positive, so X′′−2X=0 rather than −X′′+2X=0. (6) Finally you need
to simplify arbitrary constants. For...

The basic approach to use p-value to make a conclusion is: 1.
Collect sample X1, . . . , Xn from population. 2. Calculate z∗ =
X¯−µ0 σ/√µ . (If using t-test, the formular should be changed
accordingly.) 3. Calculate p-value according to the table above. 4.
Given significant level α∗, if p-value < α∗, reject the H0 with
significant level α∗. Otherwise, fail to reject H0.
Use above approach to solve the following problem!) The target
thickness for silicon...

Use R to do each of the following. Use R code instructions that
are as general as possible, and also as efficient as possible. Use
the Quick-R website for help on finding commands. 1. Enter the
following values into a data vector named Dat: 45.4 44.2 36.8 35.1
39.0 60.0 47.4 41.1 45.8 35.6 2. Calculate the difference between
the 2nd and 7th entries of this vector using only reference
indices. 3. Calculate the median of Dat. 4. Sort the...
