P(B) = P(black and A) + P(black and M) = (11+15+15)/80 = 41/80

P(A ? B) = P(black and A) = 41/80

we have P(A) = 1, P(B) = 41/80, and P(A ? B) = 41/80.

P(B | A) = P(A and B) / P(A) = (11+15+15) / (13+10+11+11+15+7+15+18) = 41/80. This represents the probability of a randomly selected black car having an automatic transmission.

P(A | C') = P(A and C') / P(C') = (10+11+15+18) / (10+11+15+18+7+11+11+15) = 54/73. This represents the probability of a randomly selected non-white car having an automatic transmission.

a) From the table, we can calculate the following probabilities:

P(A) = P(A and white) + P(A and blue) + P(A and black) + P(A and red) = (13+10+11+11+15+7+15+18)/80 = 80/80 = 1

P(B) = P(black and A) + P(black and M) = (11+15+15)/80 = 41/80

P(A ? B) = P(black and A) = 41/80

So, we have P(A) = 1, P(B) = 41/80, and P(A ? B) = 41/80.

b) We can calculate the following conditional probabilities:

P(A | B) = P(A and B) / P(B) = (11+15+15) / (11+10+11+15+7+15+18) = 41/77. This represents the probability of a randomly selected car having an automatic transmission, given that it is black.

P(B | A) = P(A and B) / P(A) = (11+15+15) / (13+10+11+11+15+7+15+18) = 41/80. This represents the probability of a randomly selected black car having an automatic transmission.

c) We can calculate the following conditional probabilities:

P(A | C) = P(A and C) / P(C) = (13+15) / (13+10+11+15) = 28/49. This represents the probability of a randomly selected white car having an automatic transmission.

P(A | C') = P(A and C') / P(C') = (10+11+15+18) / (10+11+15+18+7+11+11+15) = 54/73. This represents the probability of a randomly selected non-white car having an automatic transmission.

This means that the probability that a car is automatic given that it is black is 11/26

P(B | A) = P(A and B)/P(A)

P(B | A) = (11/100)/(9/20)

P(B | A) = 11/45

This means that the probability that a car is black given that it is automatic is 11/45

The formula expressing [tex]S_n[/tex] as a function of n for the recurrence relation [tex]S_n=-S_{n-1}+10[/tex] and initial condition [tex]S_0=-4[/tex] is [tex]S_n = 5n-4[/tex] if n is even and [tex]S_n = -5n+14[/tex]  if n is odd.

if n is even, and[tex]S_n = 5n - 4[/tex]  if n is odd.

The given recurrence relation is:

[tex]S_n = -S_{n-1} + 10[/tex]

And the initial condition is:

[tex]S_0 = -4[/tex]

To use the method of iteration, we start by substituting n-1 for n in the recurrence relation:

[tex]S_{n-1} = -S_{n-2} + 10[/tex]

Next, we can substitute this expression into the original recurrence relation:

[tex]S_n = -(-S_{n-2} + 10) + 10[/tex]

Simplifying this, we get:

[tex]S_n = S_{n-2}[/tex]

We can continue this process of substitution, getting:

[tex]S_{n-2} = -S_{n-3} + 10[/tex]

Simplifying, we get:

[tex]S_n = S_{n-3} - 10[/tex]

Substituting again:

[tex]S_{n-3} = -S_{n-4} + 10[/tex]

Simplifying:

[tex]S_n = S_{n-4} - 20[/tex]

We can see a pattern emerging: each time we substitute, we go back two steps and subtract 10 or 20.

So we can write the general formula for [tex]S_n[/tex] in terms of [tex]S_0[/tex] as follows:

If n is even:

[tex]S_n = S_0 + 10\times (n/2)[/tex]

If n is odd:

[tex]S_n = -S_0 - 10\times ((n-1)/2)[/tex]

Using the initial condition [tex]S_0 = -4,[/tex] we can simplify these formulas:

If n is even:

[tex]S_n = -4 + 10\times (n/2) = 5n - 4[/tex]

If n is odd:

[tex]S_n = 4 - 10\times ((n-1)/2) = -5n + 14.[/tex]

The formula expressing [tex]S_n[/tex] as a function of n for the given recurrence relation and initial conditions is: [tex]S_n = 5n - 4[/tex]

To use the method of iteration, we need to repeatedly apply the recurrence relation to the initial condition and previous terms until we reach the nth term.

Starting with S0 = -4, we can find S1 by plugging in n=1 into the recurrence relation:

S1 = -S0 + 10 = -(-4) + 10 = 14

Using S1, we can find S2:

S2 = -S1 + 10 = -(14) + 10 = -4

We can continue this process to find the first few terms:

S3 = -S2 + 10 = -(-4) + 10 = 14
S4 = -S3 + 10 = -(14) + 10 = -4

Notice that S2 and S4 are the same value, and S1 and S3 are the same value. This suggests that the sequence alternates between two values: -4 and 14.

We can write this as a formula:

S(n) = -4 if n is even
S(n) = 14 if n is odd

Alternatively, we could write it as:

S(n) = (-1)^n * 9 + 5

This formula also produces alternating values of -4 and 14, and can be derived using the method of recurrence relations.

The distribution of S(t) in the Black-Scholes model, where the underlying asset follows a geometric Brownian motion.

We have:

Zn(t) = ln(Sn(t))

= ln(S(0)) − [n t] + ln(1 + σ √[n t] [M[n t] 2 − [n t]]) − ln(1 − σ √[n t] [M[n t] 2 − [n t]])

= ln(S(0)) − [n t] + ln(1 + σ √[n t] W(n)(t)) − ln(1 − σ √[n t] W(n)(t))

where we have used M[n t] = W(n)(t)√[n t] and the fact that ln(1 + x) ≈ x − x^2/2 for small x.

Using the Taylor series expansion of ln(1 + x) at the order 2, we have:

ln(1 + σ √[nt] W(n)(t)) ≈ σ √[nt] W(n)(t) − σ^2/2 [nt] W(n)(t)^2

ln(1 − σ √[nt] W(n)(t)) ≈ −σ √[nt] W(n)(t) − σ^2/2 [nt] W(n)(t)^2

Substituting these into the expression for Zn(t) yields:

Zn(t) ≈ ln(S(0)) − [nt] + σ √[nt] W(n)(t) − σ^2/2 [nt] W(n)(t)^2 − (−σ √[nt] W(n)(t) − σ^2/2 [nt] W(n)(t)^2)

= ln(S(0)) − [nt] + σ^2 [nt] W(n)(t)^2

Taking the limit as n → ∞, we have:

Z(t) = lim n→∞ Zn(t)

= ln(S(0)) − tσ^2/2

This means that the distribution of Zn(t) converges to a normal distribution with mean ln(S(0)) − tσ^2/2 and variance σ^2t. Since Zn(t) approximates ln(Sn(t)), the distribution of Sn(t) converges to a lognormal distribution with mean S(0) e^(−tσ^2/2) and variance S(0)^2 (e^(σ^2t) − 1).

To express 2/3 and 3/4 as a pair of fractions with a common denominator, we can find the least common multiple (LCM) of the denominators and then adjust the numerators accordingly.

To begin, we need to find the least common multiple (LCM) of the denominators, which in this case is 12. Next, we convert 2/3 and 3/4 to fractions with a common denominator of 12.
For 2/3, we multiply both the numerator and denominator by 4 to get 8/12. Since 2 multiplied by 4 is 8, and 3 multiplied by 4 is 12.
For 3/4, we multiply both the numerator and denominator by 3 to get 9/12. Since 3 multiplied by 3 is 9, and 4 multiplied by 3 is 12.
Now, we have 8/12 and 9/12 as a pair of fractions with a common denominator of 12. These fractions can be compared or used in further calculations since they have the same denominator.

To determine whether the sequence is non-decreasing or non-increasing, we need to examine the signs of aₙ₊₁ − aₙ for all n. So, let's find the first few terms of the sequence:

a₁ = 1/2(a₀ + 2/a₀) = 1/2(2 + 1) = 3/2

a₂ = 1/2(a₁ + 2/a₁) ≈ 1.5288

a₃ = 1/2(a₂ + 2/a₂) ≈ 1.4991

Since a₃ < a₂, the sequence is non-increasing.

b.

To find the limit of the sequence, we can use the fact that it is bounded and monotonic, and apply Theorem 10.5. Let L be the limit of the sequence, then taking the limit of both sides of the recurrence relation, we get:

L = 1/2(L + 2/L)

Multiplying both sides by 2L, we get:

2L² = L² + 4

Meghan takes 1 1/4 hours to read 1/3 of her book. At this pace, it will take her 2 1/2 hours to read the entire book. Therefore, it will take her 1 1/4 hours to read 1/2 of the book.

To find out how long it will take Meghan to read the entire book, we can set up a proportion based on the fraction of the book she reads in a given time. If Meghan reads 1/3 of the book in 1 1/4 hours, we can set up the following proportion:

(1/3 book) / (1 1/4 hours) = (1 book) / (x hours)

To solve for x, we can cross-multiply and then divide:

(1/3) * (x hours) = (1) * (1 1/4 hours)

x/3 = 5/4

Next, we can multiply both sides of the equation by 3 to isolate x:

x = (5/4) * 3

x = 15/4

x = 3 3/4 hours

So, it will take Meghan 3 3/4 hours to read the entire book.

To determine how long it will take her to read 1/2 of the book, we can divide the total time by 2:

(3 3/4 hours) / 2 = 15/4 hours / 2

= (15/4) / 2

= (15/4) * (1/2)

= 15/8

Using the squeeze theorem, we found that the limit of the sequence cos(1/n) -1 as n approaches infinity is 0, and the limit of the sequence 1/n as n approaches infinity is also 0.

To use the squeeze theorem to find the limit of a sequence, we need to find two other sequences that "squeeze" the original sequence, meaning they are always greater than or equal to it and less than or equal to it. Then, if these two sequences both converge to the same limit, we know the original sequence also converges to that limit.

For the sequence cos(1/n) -1, we can use the fact that -2 ≤ cos(x) - 1 ≤ 0 for all x. Therefore, we can rewrite the sequence as:

-2/n ≤ cos(1/n) - 1 ≤ 0/n

Taking the limit as n approaches infinity of each part of the inequality, we get:

lim (-2/n) = 0
lim (0/n) = 0

So, by the squeeze theorem, the limit of cos(1/n) -1 as n approaches infinity is 0.

For the sequence 1/n, we can simply see that as n approaches infinity, the denominator gets larger and larger, so the fraction gets smaller and smaller. Therefore, the limit of 1/n as n approaches infinity is 0.

In summary, using the squeeze theorem, we found that the limit of the sequence cos(1/n) -1 as n approaches infinity is 0, and the limit of the sequence 1/n as n approaches infinity is also 0.

To find the particular solution to the differential equation y′=3x3 that passes through (1,4.75), we need to use the given general solution y=c 3x44.

First, we differentiate the general solution to get y′=12cx33.

Next, we substitute the point (1,4.75) into the equation:

4.75 = c 3(1)^4 + C

where C is the constant of integration.

Simplifying this equation, we get:

4.75 = 3c + C

To find the value of C, we need to solve for it. We can do this by using the fact that the particular solution passes through the point (1,4.75). Substituting these values into the equation above, we get:

4.75 = 3c + C

4.75 = 3c + C

4.75 - 3c = C

So C = 4.75 - 3c.

Now we substitute this value of C back into the general solution to get the particular solution:

y = c 3x44

y = (4.75 - 3c) 3x44

Therefore, the particular solution to the differential equation y′=3x3 that passes through (1,4.75), given that y=c 3x44 is a general solution, is y = (4.75 - 3c) 3x44.

The taylor polynomials for 2 is [tex]7 + 7x^2[/tex] and for 3 is [tex]7x + (7/3)x^3.[/tex]

To find the Taylor polynomials for a function, we need to calculate the function's derivatives at the point where we want to center the polynomials. In this case, we want to center the polynomials at x=0.

First, let's find the first few derivatives of[tex]f(x) = 7tan(x):[/tex]

[tex]f(x) = 7tan(x)[/tex]

[tex]f'(x) = 7sec^2(x)[/tex]

[tex]f''(x) = 14sec^2(x)tan(x)[/tex]

[tex]f'''(x) = 14sec^2(x)(2tan^2(x) + 2)[/tex]

[tex]f''''(x) = 56sec^2(x)tan(x)(tan^2(x) + 1) + 56sec^4(x)[/tex]

To find the Taylor polynomials, we plug these derivatives into the Taylor series formula:

[tex]P_n(x) = f(0) + f'(0)x + (f''(0)x^2)/2! + ... + (f^n(0)x^n)/n![/tex]

For n=2:

[tex]P_2(x) = f(0) + f'(0)x + (f''(0)x^2)/2![/tex]

[tex]= 7tan(0) + 7sec^2(0)x + (14sec^2(0)tan(0)x^2)/2[/tex]

[tex]= 7 + 7x^2[/tex]

So the second-degree Taylor polynomial centered at x=0 for f(x) is [tex]P_2(x) = 7 + 7x^2.[/tex]

For n=3:

[tex]P_3(x) = f(0) + f'(0)x + (f''(0)x^2)/2! + (f'''(0)x^3)/3![/tex]

[tex]= 7tan(0) + 7sec^2(0)x + (14sec^2(0)tan(0)x^2)/2 + (14sec^2(0)(2tan^2(0) + 2)x^3)/6[/tex]

[tex]= 7x + (7/3)x^3[/tex]

So the third-degree Taylor polynomial centered at x=0 for f(x) is [tex]P_3(x) = 7x + (7/3)x^3.[/tex]

The triangle in the image is a right triangle. We are given a side and an angle, and asked to find another side. Therefore, we should use a trigonometric function.

Trigonometric Functions: SOH-CAH-TOA

---sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, tangent = opposite/adjacent

In this problem, looking from the angle, we are given the adjacent side and want to find the opposite side. This means we should use the tangent function.

tan(40) = x / 202

x = tan(40) * 202

x = 169.498

x (rounded) = 169 meters

Answer: the tower is 169 meters tall

Hope this helps!

Answer:

170 meters

Step-by-step explanation:

The three sides of a right triangle are named hypotenuse, adjacent side and opposite side and the angle the adjacent side makes with they hypotenuse is θ  (see Figure 1)

In this description the terms
     Opposite --> side  opposite to the angle θ

      Adjacent --> side adjacent  to the angle θ

      Hypotenuse --> longest side of the right triangle

The relationship between the ratio of the shorter sides and and the angle θ in the figure is given by the formula

[tex]\mathrm {\tan(\theta) = \dfrac{Opposite \; side}{Adjacent \;side}}[/tex]

We can view the Eiffel Tower as the opposite side, the distance from the base to the surveyor location as the adjacent side (see the second figure)

If we let h = height of the Eiffel Tower in meters , opposite side length = h m

The adjacent side length = 202 meters

The angle θ = 40°

Applying the tan formula we get
[tex]\tan(40^\circ) = \dfrac{h}{202}\\\\\textrm{Multiplying both sides by 202, }\\202 \tan(40^\circ) = h\\\\\\h = 202 \tan(40^\circ) \\\textrm{Using a calculator we get}\\\\h = 169.5\; meters[/tex]

Rounded to the nearest meter, the height = 170 meters

The circle with a center at (0, 0) and passing through (0, -3) has an area and circumference that can be calculated. The area can be found using the formula A = πr^2, and the circumference can be found using the formula C = 2πr, where r is the radius of the circle.

Given that the center of the circle is at (0, 0) and it passes through (0, -3), we can determine that the radius of the circle is 3 units. The distance between the center (0, 0) and the point on the circle (0, -3) gives us the radius.

To find the area of the circle, we use the formula A = πr^2. Substituting the radius, we have A = π(3^2) = 9π square units.

To find the circumference of the circle, we use the formula C = 2πr. Substituting the radius, we have C = 2π(3) = 6π units.

Therefore, the area of the circle is 9π square units, and the circumference of the circle is 6π units.

The representation is guaranteed to be valid for values of dc + 0.24 such that |dc + 0.24| < 1, or -1.24 < dc < 0.76.

We know that the power series representation of the function f(z) = 1/(1-z) is:

f(z) = ∑(n=0 to infinity) z^n

If we substitute z = dc + 0.24 into this power series, we get:

f(dc + 0.24) = ∑(n=0 to infinity) (dc + 0.24)^n

To get this in a form we can work with, we can expand the binomial term using the binomial theorem:

f(dc + 0.24) = ∑(n=0 to infinity) [(d^0 * 0.24^n)/0! + (d^1 * 0.24^(n-1))/1! + (d^2 * 0.24^(n-2))/2! + ...] * dc^n

We can simplify this expression by writing out the first few terms explicitly:

f(dc + 0.24) = 1 + (dc + 0.24) + (dc + 0.24)^2 + (dc + 0.24)^3 + ...

The first four nonzero terms are:

1 + (dc + 0.24) + (dc^2 + 0.48dc + 0.0576) + (dc^3 + 0.72dc^2 + 0.2688dc + 0.031104)

The full series with summation notation is:

∑(n=0 to infinity) [(d^0 * 0.24^n)/0! + (d^1 * 0.24^(n-1))/1! + (d^2 * 0.24^(n-2))/2! + ...] * dc^n

The representation is guaranteed to be valid for values of z such that |z| < 1, since this is the radius of convergence of the power series for 1/(1-z).

Therefore, the representation is guaranteed to be valid for values of dc + 0.24 such that |dc + 0.24| < 1, or -1.24 < dc < 0.76.
