Please explained using the inference rules and also show all steps. In each part below, give a formal proof that the sentence given is valid or else provided an interpretation in which the sentence is false.

(a) ∀xP' (x) → ∃x[P(x) → Q'(x)].

(b) ∃x[P(x) → Q'(x)] → ∃xP' (x).

Please show all steps, thank you! a) Verify that the functions below solve the system: x(t) = c1e^5t + c2e^-t y(t) = 2c1e^5t - c2e^-t Do not solve the system dx/dt = x + 2y dy/dt = 4x +3y b) Solve the system using Operator D elimination. Write the answer both in scalar and vector form. Please show all steps! dx/dt = x + 2y dy/dt = 4x + 3y

Conduct an appropriate hypothesis test using the provided information [Neatly show all steps / necessary calculations, including both a complete comparison & interpretation statement AND plain English inference statement]. Thirty participants in an after-school tutoring program complete a comprehension test [test 1] on the day the program starts. After six weeks, the same students complete another test of their comprehension [test 2]. A random sampling of the participants forms the dataset provided below. Is there a statistically significant difference between...

please show all steps Q.9 The number of times a batter gets to bat in a game follows a binomial distribution N ∼ Binomial(6, 0.8). Given the number of times N = n that the better has at bat, the number of hits he gets conditionally follows a binomial distribution as well, (X|N = n) ∼ Binomial(n, 0.3) (a) Find E[X] (b) Find Var[X] (c) Find Cov[X, N] (d) Find ρ[X, N]
