We are given the polynomial

Find the roots:

To find the roots of this polynomial, we want to solve the following equation

On the left side, we can factor the polynomial as follows

This leads to the following two equations

with solution x=0, and the equation

by subtracting -2 from both sides , we get

Finally, by dividing both sides by -7, we get

So, the roots of this polynomial are x=0 and x=2/7.

Describe the end behavior:

To describe the end behavior of a polynomial we should first see how the polynomial is written

In here, we see that we have a power of 4 and a power of 3. Consider that the power of 4, as x grows bigger and bigger (or smaller and smaller) the power of 4 will dominate the behavior of the polynomial as x⁴ grow bigger and bigger than x³. So, we can forget the other part and focus on the polynomial

Note that as x is a positive number, then x^4 is also a positive number. So as x grows bigger and bigger, we would get a more negative number, since we are multiplying -7 (a negative number) with a really big positive number (x^4). Then this polynomial will go to - infinity as x grows bigger and bigger.

Also, to understand the end behaviour, we should see how the polynomial behaves as x becomes a really negative number. As before, we can only focus on the polynomial

note that if x is a negative number, x^4 is again a positive number. So, as x becomes more negative (approaching - infinity) the number -7x^4 would once again be a negative number. So, the end behavior as x goes - infinity is also - infinity.

We are given directions and position change.

This is about the velocity, the speed doesn't take into account the direction.

We also see the change in the velocity. The numbers give us instantaneous velocities and the displacement is the average velocity as the sum of vectors.

The number of Hopper's steps that is equivalent to one of Skipper's jumps is given as follows:

2.45.

The situation can be modeled by a system of equations.

The variables for the system of equations are given as follows:

Hopper takes three jumps, he lands in the same place as Skipper does when she takes 4 jumps, hence:

3x = 4y.

x = 4/3y.

When Hopper takes six jumps and nine steps, he lands in the same place as Skipper does when she takes nine jumps, hence:

6x + 9z = 9y.

Replacing x = 4/3y on the second equation, we have that:

4(4/3y) + 9z = 9y.

9z = 9y - 16/3y

9z = 27/3y - 16/3y

9z = 11/3y

y = 27/11z

y = 2.45.

Meaning that 2.45 of Hopper's steps are equivalent to one of Skipper's jumps.

For cumulative distribution function;

e[v] = 1.25.

var[v] = 53.02.

we need to integrate v*fv(v) over the entire range of v?

e[v] = ∫v*fv(v) dv from -∞ to ∞

= ∫v*0 dv from -∞ to -5 + ∫v*(v+5)²/144 dv from -5 to 7 + ∫v*1 dv from 7 to ∞

= 0 + [(v³/36 + 5v²/24 + 25v/72) from -5 to 7] + 0

= [(7³/36 + 5*7²/24 + 25*7/72) - (-5³/36 + 5*(-5)²/24 + 25*(-5)/72)]

= 1.25

Therefore, e[v] = 1.25.

To find var[v], we need to first find e[v²]:

e[v²] = ∫v²*fv(v) dv from -∞ to ∞

= ∫v²*0 dv from -∞ to -5 + ∫v²*(v+5)²/144 dv from -5 to 7 + ∫v²*1 dv from 7 to ∞

= 0 + [(v⁴/48 + 5v³/36 + 25v²/144) from -5 to 7] + ∞

= [(7⁴/48 + 5*7³/36 + 25*7²/144) - (-5⁴/48 + 5*(-5)³/36 + 25*(-5)²/144)]

= 54.86

Therefore, e[v²] = 54.86.

Now we can find var[v] using the formula:

var[v] = e[v²] - (e[v])²

= 54.86 - (1.25)²

= 53.02

Therefore, var[v] = 53.02.

The given statement "The misuse of statistics is sometimes intentional." is True, because there are instances where people intentionally misuse statistics to manipulate or deceive others.

The misuse of statistics can be an intentional act by individuals or organizations to manipulate or deceive others. This is often done by selectively choosing data or statistics that support a particular argument or position, while ignoring or downplaying information that does not support it.

One way this can be achieved is by distorting graphs or charts. For example, a bar chart can be designed to visually exaggerate the differences between data points, making the differences appear more significant than they actually are. This can be done by adjusting the scale of the chart or by changing the width of the bars.

Another way that statistics can be misused is by making false claims based on the data. For example, someone may use a correlation between two variables to imply a causal relationship, even though there may not be any evidence to support this claim.

Similarly, statistics can be used to mislead people by presenting them in a way that is misleading. For example, a statistic may be presented without any context or compared to an irrelevant baseline, making it appear more significant or less significant than it actually is.

(a) the time-domain signal \(x(t)\) is given by \(x(t) = u(t) \cdot \delta(t+2)\).\

(b) the signal \(x(t) = u(t) \cdot \delta(t+2)\) is both causal and absolutely integrable.

(a) To find the time-domain signal \(x(t)\) given the Laplace transform \(X(s) = e^{-2s}\), we need to perform an inverse Laplace transform. In this case, the inverse Laplace transform of \(X(s)\) can be found using the formula:

\[x(t) = \mathcal{L}^{-1}\{X(s)\} = \mathcal{L}^{-1}\{e^{-2s}\}\]

The inverse Laplace transform of \(e^{-2s}\) can be computed using known formulas, specifically:

\[\mathcal{L}^{-1}\{e^{-a s}\} = u(t) \cdot \delta(t-a)\]

where \(u(t)\) is the unit step function and \(\delta(t)\) is the Dirac delta function.

Using this formula, we can determine \(x(t)\) by substituting \(a = -2\):

\[x(t) = u(t) \cdot \delta(t+2)\]

Therefore, the time-domain signal \(x(t)\) is given by \(x(t) = u(t) \cdot \delta(t+2)\).

(b) If a signal is causal and absolutely integrable, it implies that the signal is nonzero only for non-negative values of time and has a finite total energy. In the case of the signal \(x(t) = u(t) \cdot \delta(t+2)\), it is causal because it is multiplied by the unit step function \(u(t)\), which ensures that \(x(t)\) is zero for \(t < 0\).

To determine if \(x(t)\) is absolutely integrable, we need to check the integral of the absolute value of \(x(t)\) over its entire range. In this case, the integral would be:

\[\int_{-\infty}^{\infty} |x(t)| \, dt = \int_{-\infty}^{\infty} |u(t) \cdot \delta(t+2)| \, dt\]

Since the Dirac delta function \(\delta(t+2)\) is zero everywhere except at \(t = -2\), the integral becomes:

\[\int_{-\infty}^{\infty} |x(t)| \, dt = \int_{-\infty}^{\infty} |u(t) \cdot \delta(t+2)| \, dt = \int_{-2}^{-2} |u(t) \cdot \delta(t+2)| \, dt = 0\]

Therefore, the signal \(x(t) = u(t) \cdot \delta(t+2)\) is both causal and absolutely integrable.

the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3

To write the system of ordinary differential equations (ODEs) for the transition probabilities Pᵢⱼ(t) of the given continuous-time Markov chain, we need to consider the rate at which the system transitions between different states.

Let Pᵢⱼ(t) represent the probability that the Markov chain is in state j at time t, given that it started in state i at time 0.

The ODEs for the transition probabilities can be written as follows:

dP₁₂(t)/dt = q₁₂ * P₁(t) - q₂₁ * P₂(t)

dP₁₃(t)/dt = q₁₃ * P₁(t) - q₃₁ * P₃(t)

dP₂₁(t)/dt = q₂₁ * P₂(t) - q₁₂ * P₁(t)

dP₂₃(t)/dt = q₂₃ * P₂(t) - q₃₂ * P₃(t)

dP₃₁(t)/dt = q₃₁ * P₃(t) - q₁₃ * P₁(t)

dP₃₂(t)/dt = q₃₂ * P₃(t) - q₂₃ * P₂(t)

where P₁(t), P₂(t), and P₃(t) represent the probabilities of being in states 1, 2, and 3 at time t, respectively.

Now, let's consider the second part of the question: Suppose that the initial state is 1. We want to find the probability that after the first transition, the process X(t) enters state 2.

To calculate this probability, we need to find the transition rate from state 1 to state 2 (q₁₂) and normalize it by the total rate of leaving state 1.

The total rate of leaving state 1 can be calculated as the sum of the rates to transition from state 1 to other states:

total_rate = q₁₂ + q₁₃

Therefore, the probability of transitioning from state 1 to state 2 after the first transition can be calculated as:

P(X(t) enters state 2 after the first transition | X(0) = 1) = q₁₂ / total_rate

In this case, the transition rate q₁₂ is 1, and the total rate q₁₂ + q₁₃ is 1 + 2 = 3.

Therefore, the probability of transitioning from state 1 to state 2 after the first transition is:

P(X(t) enters state 2 after the first transition | X(0) = 1) = 1 / 3
