1. Identify each of the following statements as true of false and explain your reasoning in full sentences. The domain of discourse is the integers.

(a) ∃x∀y(y > x)

(b) ∀y∃x(y > x)

(c) ∃x(x = 0 → x = 1)

2. Write the formal negation of the following statements. Your negation must not contain any explicit negation symbols.

(a) ∀x∃y(2 < x ≤ y)

(b) ∀y∃x(y > 0 → x ≤ 0)

3. Negate verbally:
(a) ”All people weigh at least 100 pounds.”

(b) ”Somebody did not see any animals in the zoo”

4. If P and Q are predicates over some domain, and if it is true that∀x(P(x)∨ Q(x)), must ∀xP(x)∨∀xQ(x) also be true? Explain.

Locate the results of a recent survey that show at least two variables in a newspaper, magazine, or internet article. Outline the survey data so that your peers can understand the variables and results. Then identify at least one key statistical inference formula involving two of more parameters that you could use to evaluate the data. Provide a brief explanation of why you selected the formula you did and why it matters. Also, explain what the formula is and where it is in the textbook and clearly define your parameters. Do not use regression or correlation examples since we will cover them during the next module.

Two​ drivers, Alison and​ Kevin, are participating in a race. Beginning from a standing​ start, they each proceed with a constant acceleration. Alison covers the last 1/9 of the distance in

7 seconds, whereas Kevin covers the last 1/7 of the distance in 9 seconds. Who wins and by how much​ time?

In Exercises 5–37, solve the given differential equations by Laplace transforms. The function is subject to the given conditions.

13. 4y″ + 4y′ + 5y = 0, y(0) = 1, y′(0) = -1/2

17. y″ + y = 1, y(0) = 1, y′(0) = 1

The Alternate Interior Theorem states that if two lines cut by a transversal line have a pair of congruent alternate interior angles, then they must be parallel. Prove this theorem in Neutral Geometry (first 4 axioms) in two ways

1) using the exterior angle theorem

2) then without.

Hint: use proof by contradiction for both solutions.

Please state these definition and use detal and espilon:

(fn) is a sequence if function:

1.What is the definition of (fn) is continuous?

2.What is the definition of (fn) is uniformly continuous?

3.What is the difference between the function continuous and the sequence of function continuous?

Compute, by Euler’s method, an approximate solution to the following initial value problem for h = 1/8 : y’ = t − y , y(0) = 2 ; y(t) = 3e^(−t) + t − 1 . Find the maximum error over [0, 1] interval.

Summarize seperable equations, integrating factor, exact equations, and auxiliary equation in your own words and what mathematical skills are needed in each technique. Please no handwriting unless I can read it please.

descriptively detail how methods and applications of discrete random variables and continuous random variables are used to support areas of industry research, academic research, and scientific research.

Show all the step and don't be lazy. You will get thumbs down. Otherwise...Thumb down

If you cannot follow the comment, don't answer it

Please clear writing and explain step by step this should be a simple question. I will know if you understand this topic or not.

Consider the function f : [0,1]→R defined by (f(x) =0 if x = 0) and (f(x)=1 if 0 < x≤1)

(i)Compute L(f) andU(f).

(ii) Is f Riemann integrable on [0,1]?

“We must differentiate our mindset first and our lessons second.” (Dweck, 2012). What does this saying mean to you? In your own words, what is the difference between differentiation and tracking?

Use the Laplace transform to solve the following initial value problem:

?″+6?′+58?=?(?−4)

?(0)=0,?′(0)=0

(Notation: write u(t-c) for the Heaviside step function ??(?)uc(t) with step at ?=?t=c.)

1. A small furniture manufacture producer tables and chairs.  Each product must go through three stages of the manufacturing process:

Each table requires 4 hours of assembly, 3 hours of finishing and 1 hour of inspection

Each chair requires 3 hours of assembly, 2hours of finishing and 2 hours of inspection

The selling price per table is $140 while the selling price per chair is $90

Currently, each week there are 220 hours of assembly time available, 160 hours of finishing time, and 45 hours of inspection time.

Assume that one hour of assembly time costs $.00; one hour of finishing time costs $6.00; one hour of inspection time costs $4.50.

Linear programming is to be used to develop a production schedule.

Let:      T=number of tablets produced each week

            C=number of chairs produced each week

Which of the following expression would be the objective function of this LP problem?

1. Max 140T+90C
2. Max 97.5T+54C
3. Max T+C
4. Min 42.5T+36C
