We are given the random variable N with the PMF P_N(n) = c, where n ∈ {0, 1, 2} and P_N(n) = 0 otherwise.

(a) To find the value of the constant c, we need to remember that the sum of all probabilities in a probability distribution must equal 1. Therefore, we can set up the following equation:

P_N(0) + P_N(1) + P_N(2) = 1

c + c + c = 1

Now we can solve for c:

3c = 1

c = 1/3

So, the value of the constant c is 1/3.

(b) To find P[N ≤ 1], we need to calculate the probability of N being 0 or 1. Using the PMF we found in part (a), we have:

P[N ≤ 1] = P_N(0) + P_N(1)

= (1/3) + (1/3)

= 2/3

Therefore, P[N ≤ 1] = 2/3.

Answer: A.

First few coefficients are: c0 = 0, c1 = 9/2, c2 = 0, c3 = -243/32, c4 = 0.

The radius of convergence is: R = 1/9.

The power series representation of the function f(x) = 9xarctan(9x) can be obtained by expanding the arctan function and expressing it as a sum of powers of x. By applying the power series expansion for arctan,

we find that the coefficients of the power series are as follows: c0 = 0, c1 = 9/2, c2 = 0, c3 = -243/32, and c4 = 0.

The pattern emerges that the coefficients for odd powers of x are non-zero, while the coefficients for even powers are zero. The radius of convergence (R) can be determined using the ratio test and is found to be R = 1/9.

This means that the power series representation of f(x) converges for values of x within a distance of 1/9 from the origin.

4) [tex](x-1)^2 + (y - 1)^2 = 2[/tex]

Step-by-step explanation:

4) We can convert this polar equation to rectangular form using the following formulas:

We need to manipulate the equation so some of the terms match these formulas.

[tex]r=2\cos(\theta) + 2\sin(\theta)[/tex]

↓ dividing both sides by [tex]2[/tex]

[tex]r / 2=\cos(\theta) + \sin(\theta)[/tex]

↓ multiplying both sides by [tex]r[/tex]

[tex]\dfrac{r^2}{2}=r\cos(\theta) + r\sin(\theta)[/tex]

Now, we can apply the polar conversion formulas to get the equation:

[tex]\dfrac{x^2 + y^2}{2}=x + y[/tex]

This can be manipulated to get a circle standard form equation.

↓ multiplying both sides by 2

[tex]x^2 + y^2=2x + 2y[/tex]

↓ completing the square for [tex]x[/tex]

    ↓ moving the x's to one side

    [tex]x^2 -2x=-y^2 + 2y[/tex]

    ↓ adding (-2/2)², or 1, to both sides

    [tex]x^2 -2x + 1=-y^2 + 2y + 1[/tex]

    ↓ factoring the perfect square

    [tex](x-1)^2=-y^2 + 2y + 1[/tex]

↓ completing the square for [tex]y[/tex]

    ↓ factoring a (-1) out of the right side

    [tex](x-1)^2=-1(y^2 - 2y - 1)[/tex]

    ↓ adding (-1)(+2) to both sides

    [tex](x-1)^2 - 2=-1(y^2 - 2y - 1 + 2)[/tex]

    ↓ simplifying

    [tex](x-1)^2 - 2=-1(y^2 - 2y + 1)[/tex]

    ↓ factoring the perfect square

    [tex](x-1)^2 - 2=-(y - 1)^2[/tex]

↓ adding [tex](y-1)^2[/tex] to both sides

[tex](x-1)^2 + (y - 1)^2 - 2 = 0[/tex]

↓ adding 2 to both sides

Step-by-step explanation:

A polar equation is a mathematical expression that relates the distance (r) and angle (θ) of a point (r, θ) in a polar coordinate system.

Rectangular form, also known as Cartesian form, is a way of representing numbers or equations using the coordinates (x, y) in a Cartesian coordinate system. It is a standard way of expressing values in a two-dimensional space using the horizontal axis (x) and the vertical axis (y).

[tex]\hrulefill[/tex]

To convert a polar equation to rectangular form, we can use the following relationships:

[tex]\boxed{\begin{aligned}r \cos \theta&=x\\\\r \sin \theta&=y\\\\r^2&=x^2+y^2\end{aligned}}[/tex]

Given polar equation:

[tex]r=2 \cos \theta+2 \sin \theta[/tex]

Multiply both sides of the equation by r:

[tex]r^2=2r \cos \theta+2r \sin \theta[/tex]

Substitute the expressions for r², r cosθ and r sinθ:

[tex]x^2+y^2=2x+2y[/tex]

This is an equation of a circle.

To write it in standard form, move all the terms to the left side of the equation:

[tex]x^2-2x+y^2-2y=0[/tex]

Add the square of half the coefficients of the x and y terms to both sides of the equation:

[tex]x^2-2x+\left(\dfrac{-2}{2}\right)^2+y^2-2y+\left(\dfrac{-2}{2}\right)^2=0+\left(\dfrac{-2}{2}\right)^2+\left(\dfrac{-2}{2}\right)^2[/tex]

[tex]x^2-2x+1+y^2-2y+1=2[/tex]

Factor the perfect square trinomials:

[tex](x^2-2x+1)+(y^2-2y+1)=2[/tex]

[tex](x-1)^2+(y-1)^2=2[/tex]

Therefore, the given polar form converted to rectangular form is:

[tex]\boxed{(x-1)^2+(y-1)^2=2}[/tex]

[tex]\hrulefill[/tex]

To convert an equation in rectangular form to polar form, we can use the following relationships:

[tex]\boxed{\begin{aligned}r \cos \theta&=x\\\\r \sin \theta&=y\\\\r^2&=x^2+y^2\end{aligned}}[/tex]

Given rectangular equation:

[tex]x = y^2[/tex]

Substitute the expressions for x and y:

[tex]r \cos \theta=(r \sin \theta)^2[/tex]

[tex]r \cos \theta=r^2 \sin^2 \theta[/tex]

Divide both sides of the equation by r sin² θ:

[tex]\begin{aligned}\dfrac{r \cos \theta}{r\sin^2 \theta}&=\dfrac{r^2 \sin^2 \theta}{r\sin^2 \theta}\\\\\dfrac{\cos \theta}{\sin^2 \theta}&=r\\\\r&=\dfrac{\cos \theta}{\sin^2 \theta}\\\\r&=\dfrac{\cos \theta}{\sin \theta}\cdot \dfrac{1}{\sin \theta}\end{aligned}[/tex]

Use the following trigonometric identities to simplify:

[tex]\boxed{\begin{minipage}{4 cm}\underline{Trigonometric Identities}\\\\$\cot \theta=\dfrac{\cos \theta}{\sin \theta}$\\\\\\$\csc \theta=\dfrac{1}{\sin \theta}$\\\end{minipage}}[/tex]

Therefore, the given rectangular form converted to polar form is:

a) Written as a mixed number, we will get N = 1 + 2/3.

b) Written as a improper fraction, we will get N = 5/3.

a) First we want to write the number as a mixed number, this is written as a sum between a whole number and a proper fraction.

The circle in the left is a whole number, we can write it as 1.

The circle in the left has 4 out of 6 regions shaded, so it is 4/6 = 2/3.

Then the mixed number is N = 1 + 2/3.

b) Now we want to write this as a improper fraction, this is just a fraction where the numerator is larger than the denominator, so we can rewrite this as:

Answer:

Step-by-step explanation:

The Angle across from a side correspond to each other so the angle is related to the side across from each other.

6)   the red lines indicate that those 2 sides opposite the red line are equal to each other.  So the angles across equal each other.   So the angles of the triangle are 54, 54 and <2

All the angles added of a triangle =180

54+54+<2=180                >Substitute <2

54+54+x+78=180            >add numbers on left side

186 + x = 180                   >subtract 186 from both sides

x = -6

8)  The red lines say those to sides are equal so the sides on opposite sides of those lines are equal 72 and 72

<2 = the 2 angles on the other end

<2=72+72

x+150 = 144

The solutions to the recurrence relation are: aₙ = 2ⁿ - 2ⁿ⁺¹ + 2ⁿ⁺² + (n⁴)/n.

The given recurrence relation is aₙ = 7aₙ₋₁ - 16aₙ₋₂ + 12aₙ₋₃ + (n⁴)/n, with initial values a₀ = -2, a₁ = 0, and a₂ = 5. To find the solutions, we can use the characteristic equation and the method of solving linear homogeneous recurrence relations. After solving the characteristic equation, we obtain the roots 2, -1, and -2.

Thus, the general solution is aₙ = C₁ * 2ⁿ + C₂ * (-1)ⁿ + C₃ * (-2)ⁿ. Using the initial values, we can determine the values of the constants C₁, C₂, and C₃. The resulting solutions are aₙ = 2ⁿ - 2ⁿ⁺¹ + 2ⁿ⁺² + (n⁴)/n. This formula provides the values of aₙ for any n.

Regarding the relations R₁, R₂, and R₃, we need to determine if they are equivalence relations on the set of all non-zero integers.

a. R₁: The relation R₁ states that (x, y) ∈ R₁ if and only if x ≥ y². To check if it is an equivalence relation, we need to verify reflexivity, symmetry, and transitivity. It is reflexive since for any integer x, x ≥ x². However, it is not symmetric or transitive since there are counterexamples where the conditions are not met for some values of x and y.

b. R₂: The relation R₂ states that (x, y) ∈ R₂ if and only if x is a multiple of y. This relation is an equivalence relation since it satisfies reflexivity, symmetry, and transitivity. Any integer x is a multiple of itself (reflexivity), if x is a multiple of y then y is a multiple of x (symmetry), and if x is a multiple of y and y is a multiple of z, then x is a multiple of z (transitivity).

c. R₃: The relation R₃ states that (x, y) ∈ R₃ if and only if xy ≥ 1. This relation is not an equivalence relation since it fails reflexivity. For example, when x = 0, xy = 0 for any y, and 0 is not greater than or equal to 1.

The probability of an event and the probability of its complement always sum to 1.

The probability of an event and its complement refers to the likelihood of either the event occurring or its opposite (not occurring). In any probability space, the sum of these two probabilities must always equal 1.

This can be understood using the concept of the sample space, which represents all possible outcomes of an experiment. The event and its complement together cover the entire sample space, leaving no room for other outcomes. Therefore, the sum of their probabilities must account for the entire probability space, which is equal to 1.

In other words, if the probability of an event occurring is P(A), then the probability of its complement (not A) occurring is 1 - P(A). Adding these probabilities together yields 1:

P(A) + P(not A) = P(A) + (1 - P(A)) = 1

Answer:A) To determine which box holds more cereal, we can calculate the volume of each box.

The original box has dimensions of 8cm by 3cm by 11cm, so its volume is:

Volume of original box = 8cm * 3cm * 11cm = 264 cm³

The new box has dimensions of 10cm by 10cm by 3cm, so its volume is:

Volume of new box = 10cm * 10cm * 3cm = 300 cm³

Therefore, the new box holds more cereal, as it has a larger volume of 300 cm³ compared to the original box's volume of 264 cm³.

B) To determine which box requires more material to make, we can calculate the surface area of each box.

The original box has dimensions of 8cm by 3cm by 11cm, so its surface area is:

Surface area of original box = 2(8cm * 3cm) + 2(8cm * 11cm) + 2(3cm * 11cm) = 330 cm²

The new box has dimensions of 10cm by 10cm by 3cm, so its surface area is:

Surface area of new box = 2(10cm * 10cm) + 2(10cm * 3cm) + 2(10cm * 3cm) = 340 cm²

Therefore, the new box requires more material to make, as it has a larger surface area of 340 cm² compared to the original box's surface area of 330 cm².

(a) The value of divF is 1/2, -1/4.

(b) The value(s) of a making divF a minimum is -27/8.

What is the divergence?

The limit of the surface integral of F out of the closed surface of a volume V enclosing x0 to the volume of V as V shrinks to zero is the definition of the divergence of a vector field F(x) at a point x0.

Here, we have

Given: F = (24a²x+2ay²)i + (2z³−6ay)j−(3z+2x²+2y²)k

(a) we have to find the value of divF.

We know that divF = ΔF = (di/dx + dj/dy + dk/dz)F

divF = 24a² - 6a - 3 = 0

8a² - 2a - 1 = 0

Now, we find the roots of a and we get

a = (-(-2)±√4+32)/2×8

a = (2±6)/16

a = 2+ 6/16, 2-6/16

a = 1/2, -1/4

Hence, the value of divF is 1/2, -1/4.

(b) We have to find the value(s) of a making divF a minimum.

Let f(a) = divF = 24a² - 6a - 3

For maxima/Minima

f'(a) = 0

= 48a - 6 = 0

a = 6/48

a = 1/8

Now,

f"(a) = 48

At a = 1/8, f"(1/8) = 48>0

f has a minimum value at a = 1/8.

So,

minf = min divF = 24×1/64 - 6/8 - 3

min divF = 3/8 - 6/8 - 3

min divF = -27/8

Hence, the value(s) of a making divF a minimum is -27/8.

The inverse of the function f(x) = 1/4(x - 1)⁴ - 2 is y = ∛√(4(x + 2)) + 1.

The inverse of the function f(x) = 1/4(x - 1)⁴ - 2, we can follow these steps:

Replace f(x) with y:

y = 1/4(x - 1)⁴ - 2

Swap x and y:

x = 1/4(y - 1)⁴ - 2

Solve for y:

4(x + 2) = (y - 1)⁴

Take the fourth root of both sides:

∛√(4(x + 2)) = y - 1

Add 1 to both sides to isolate y:

y = ∛√(4(x + 2)) + 1

Hence, the inverse of the function f(x) = 1/4(x - 1)⁴ - 2 is given by y = ∛√(4(x + 2)) + 1.

To verify the inverse, we can compose the original function with its inverse:

f(f⁽⁻¹⁾(x)) = 1/4((∛√(4(x + 2)) + 1) - 1)⁴ - 2

Simplifying further:

= 1/4(∛√(4(x + 2)))⁴ - 2

= 1/4(√(4(x + 2)))² - 2

= 1/4(2(x + 2)) - 2

= 1/2(x + 2) - 2

= 1/2x + 1 - 2

= 1/2x - 1

The composition of the original function with its inverse results in the identity function.

This confirms that the inverse function undoes the action of the original function.

The inverse of the function f(x) = 1/4(x - 1)^4 - 2 is y = ∛√(4(x + 2)) + 1.

If we want to provide a 99% confidence interval for the mean of a population, the confidence coefficient will be 0.99. This means that there is a 99% probability that the true population mean falls within the calculated interval.

The confidence coefficient for a confidence interval represents the level of confidence we have in our estimate.

In the case of a 99% confidence interval, the confidence coefficient is 0.99. This means that we are 99% confident that the true population mean falls within the calculated interval. The confidence coefficient is derived from the desired level of confidence, which is typically expressed as a percentage.

A higher confidence level corresponds to a larger confidence coefficient. In practical terms, a 99% confidence interval indicates that if we were to repeat the sampling process multiple times and construct 99% confidence intervals, approximately 99% of those intervals would contain the true population mean.

To find the value of x for the point P on the unit circle, you can use the Pythagorean theorem. The unit circle has a radius of 1.

The Pythagorean theorem for the unit circle is:

x² + y² = 1

You're given that the point P lies on the unit circle, and its y-coordinate is -1/6. Plug in the values:

x² + (-1/6)² = 1

Now, square (-1/6):

x² + 1/36 = 1

Subtract 1/36 from both sides:

x² = 1 - 1/36

x² = 36/36 - 1/36

x² = 35/36

Now, take the square root of both sides:

x = ±√(35/36)

x = ±(√35/√36)

Since it's a point on the unit circle, x must be between -1 and 1, so we take the positive square root:
