[tex]3^{1000}[/tex]  is congruent to 80 (mod 100).

To compute[tex]3^{1000}[/tex] mod 100 by hand, we can use modular arithmetic.

First, we can break down 100 into its prime factors:[tex]100 = 2^2 \times  5^2.[/tex].  

This means that we can compute [tex]3^{1000}[/tex]  mod 100 by separately computing [tex]3^{1000}[/tex] mod [tex]2^2[/tex] and [tex]3^{1000}[/tex] mod 5^2.
To compute [tex]3^{1000}[/tex]  mod [tex]2^2[/tex], we can use the fact that [tex]3^2 = 9[/tex] is congruent to 1 mod 4.

Therefore, we can write:
[tex]3^{1000}[/tex] mod [tex]2^2 = (3^2)^{500} mod 2^2 = 1^500 mod 2^2 = 1[/tex]
To compute 3^1000 mod 5^2, we can use Euler's totient theorem, which states that if a and n are coprime (i.e. their greatest common divisor is 1), then [tex]a^phi(n)[/tex] is congruent to 1 mod n,

where phi(n) is the Euler totient function.

Since 3 and 25 are coprime (their greatest common divisor is 1), we have:
[tex]\phi(25) = (5-1)\times (5) = 20[/tex]
Therefore, we can write:
[tex]3^{1000}  mod 25 = 3^{(20\times 50)} \times  3^{10 } mod 25 = 1\times 3^{10} mod 25[/tex]

Now we just need to compute [tex]3^10[/tex] mod 25.

We can do this by repeatedly squaring and reducing mod 25:
[tex]3^2 = 9[/tex]
[tex]3^4 = 81 = 6 mod 25[/tex]
[tex]3^8 = 36^2 = 11^2 = 121 = 21 mod 25[/tex]
[tex]3^{10}  = 3^8 \times 3^2 = 21\times 9 = 189 = 14 mod 25[/tex]
Therefore, we have:
[tex]3^{1000} mod 25 = 3^{10}  mod 25 = 14[/tex]
Now we can use the Chinese remainder theorem to combine our results and find [tex]3^{1000}[/tex] mod 100.

Since [tex]2^2 and 5^2[/tex] are coprime (their greatest common divisor is 1), we can write:
[tex]3^{1000} mod 100 = (1\times25\times14 + 1\times4\times1) mod 100 = 1401 mod 100 = 1[/tex]
Therefore, [tex]3^{1000}[/tex] is congruent to 1 mod 100.

We can conclude that cov(x, y) = E[xy] - E[x] E[y] = 0 - E[x] E[y] = 0, since x and y are independent.

If x and y are independent, then their covariance cov(x, y) is equal to 0. This is because the formula for covariance is:

cov(x, y) = E[(x - E[x])(y - E[y])]

Since x and y are independent, their joint probability density function can be factored as:

f(x, y) = f(x)f(y)

where f(x) and f(y) are the marginal probability density functions of x and y, respectively. Therefore, the expected values of x and y can be written as:

E[x] = ∫x f(x) dxE[y] = ∫y f(y) dy

Then, the covariance can be expressed as:

cov(x, y) = E[(x - E[x])(y - E[y])]

= E[x y] - E[x] E[y]

Using the fact that x and y are independent, we have:

E[xy] = ∫∫x y f(x, y) dx dy

= ∫∫x y f(x) f(y) dx dy

= ∫x x f(x) dx ∫y y f(y) dy

Therefore, the limit as a definite integral is ∫[-2,3] f(x) dx, that is, 62.25.

To express the given limit as a definite integral, we need to use the definition of a Riemann sum and convert it into an integral.

The given limit can be expressed as

lim(n → ∞) ∑(k=1 to n) △x · (x_k)³

where △x = (b-a)/n is the width of each subinterval, with a = -2 and b = 3 being the endpoints of the interval [-2, 3]. We can rewrite (x_k)³ as f(x_k) and interpret the limit as the definite integral of f(x) over the interval [-2, 3]

lim(n → ∞) ∑(k=1 to n) △x · (x_k)³ = ∫[-2,3] f(x) dx

where f(x) = x³. Using the Fundamental Theorem of Calculus, we can evaluate the integral as

∫[-2,3] f(x) dx = F(3) - F(-2)

where F(x) is the antiderivative of f(x) = x³, which is F(x) = (1/4) x⁴ + C, where C is a constant of integration.

Thus, the definite integral is

The integral evaluated using Green's theorem is 0.

Green's theorem relates a line integral around a closed curve to a double integral over the region enclosed by the curve.

In this case, we are asked to evaluate the integral [tex]\int_c (3yx dx + 2x dy),[/tex]where c represents the boundary of a region denoted as 0.

Using Green's theorem, we can rewrite the given integral as the double integral of the curl of the vector field F = (3y, 2x) over the region 0.

The curl of F is obtained by taking the partial derivative of its second component with respect to x and subtracting the partial derivative of its first component with respect to y.

Since the partial derivative of 2x with respect to x is 2 and the partial derivative of 3y with respect to y is 3, the curl of F is equal to 2 - 3 = -1.

Therefore, according to Green's theorem, the given line integral is equal to the double integral of -1 over the region 0.

The value of a double integral of a constant over a region is simply the constant multiplied by the area of that region.

Since the constant in this case is -1 and the region 0 has an area of zero, the result of the integral is 0.

By using Taylor's method of order two, we can approximate the solution for the initial-value problem y = 1 + (t - y)[tex]^2[/tex], 2 ≤ t ≤ 3, y(2).

To approximate the solution for the given initial-value problem using Taylor's method of order two, we need to follow a step-by-step process. Let's break it down:

1. Identify the function and its derivatives

The initial-value problem is defined as: y = 1 + (t - y)[tex]^2[/tex], 2 ≤ t ≤ 3, y(2). Here, y represents the unknown function, and t is the independent variable. We need to find an approximation for y within the given time interval.

2.Express the function as a Taylor series

Using Taylor's method, we express the function y as a Taylor series expansion. In this case, we'll use the second-order expansion, which involves the function's first and second derivatives:

y(t + h) ≈ y(t) + hy'(t) + (h[tex]^2[/tex])/2 * y''(t)

3.Calculate the derivatives

Next, we need to calculate the first and second derivatives of y(t). Taking the derivatives of the given equation, we have:

y'(t) = -2(t - y)

y''(t) = -2

4. Substitute the derivatives into the Taylor series

Now, we substitute the derivatives we calculated into the Taylor series equation from Step 2:

y(t + h) ≈ y(t) + h * (-2(t - y)) + (h[tex]^2[/tex])/2 * (-2)

Simplifying further:

y(t + h) ≈ y(t) - 2h(t - y) - hc[tex]^2[/tex]

5. Set up the iteration process

To obtain an approximation, we iterate the formula from Step 4. Starting with the initial condition y(2) = ?, we substitute t = 2 and y = ? into the formula:

y(2 + h) ≈ y(2) - 2h(2 - y(2)) - h[tex]^2[/tex]

6. Choose a step size and perform iterations

Choose a suitable step size, h, and perform the iterations. In this case, let's choose h = 0.1 and perform iterations from t = 2 to t = 3. We'll calculate the approximate values of y at each step using the formula from Step 5.

7. Perform the calculations and update the values

Starting with the initial condition, substitute the values into the formula and calculate the new approximations iteratively:

For t = 2:

y(2.1) ≈ y(2) - 2h(2 - y(2)) - h[tex]^2[/tex]

For t = 2.1:

y(2.2) ≈ y(2.1) - 2h(2.1 - y(2.1)) - h[tex]^2[/tex]

Repeat this process until you reach t = 3, updating the value of y at each iteration.

By following these steps, you can approximate the solution for the given initial-value problem using Taylor's method of order two. Remember to adjust the step size and number of iterations based on the desired accuracy of the approximation.

On average, a customer can expect a discount of approximately 21.25% when they enter the store and receive a scratch-off card.

To calculate the overall discount a customer can expect, we need to consider the probabilities and corresponding discounts for each type of card. Let's denote the probability of getting an even number as P(even), the probability of getting an odd number greater than 4 as P(odd > 4), and the probability of getting any other number as P(other).

The discount associated with an even number is 20%, so we multiply the probability of getting an even number (1/2) by the discount (0.2) to obtain 1/2 * 0.2 = 0.1, which is equivalent to a 10% discount.

The discount associated with an odd number greater than 4 is 30%, so we multiply the probability of getting such a number (1/4) by the discount (0.3) to get 1/4 * 0.3 = 0.075, which equals a 7.5% discount.

The discount associated with any other number is 15%, so we multiply the probability of getting such a number (1/4) by the discount (0.15) to obtain

=> 1/4 * 0.15 = 0.0375, which is equal to a 3.75% discount.

To calculate the overall discount, we sum up the individual discounts: 10% + 7.5% + 3.75% = 21.25%.

Area = 0.5 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|

In this formula, the coordinates of each point are represented by x and y values. For example, A(1, 4) can be denoted as x1 = 1 and y1 = 4, B(8, 0) as x2 = 8 and y2 = 0, and C(7, 8) as x3 = 7 and y3 = 8.

Substituting these values into the formula, we have:

Area = 0.5 * |1(0 - 8) + 8(8 - 4) + 7(4 - 0)|

Simplifying the expression within the absolute value, we get:

Area = 0.5 * |-8 + 32 + 28|

Calculating the sum within the absolute value, we have:

Given the parametric equations:

r(s,t) = ⟨st, st, s-t⟩

We can calculate the partial derivatives with respect to s and t as follows:

∂r/∂s = ⟨t, t, 1⟩

∂r/∂t = ⟨s, s, -1⟩

Now, we evaluate these derivatives at the point (2, 3, 1):

∂r/∂s = ⟨3, 3, 1⟩

∂r/∂t = ⟨2, 2, -1⟩

The tangent plane at the point (2, 3, 1) can be defined by the equation:

⟨x - x₀, y - y₀, z - z₀⟩ · ⟨3, 3, 1⟩ = 0

Where (x₀, y₀, z₀) is the given point (2, 3, 1).

Expanding the dot product, we get:

(3x - 3x₀) + (3y - 3y₀) + (z - z₀) = 0

Substituting the values for x₀, y₀, and z₀, we have:

3x - 6 + 3y - 9 + z - 1 = 0

Simplifying further:

Answer: the price of one senior citizen ticket is $10, and the price of one student ticket is $5.

Step-by-step explanation:

Let's assume the price of one senior citizen ticket is 's' dollars and the price of one student ticket is 't' dollars.

According to the given information, on the first day, the school sold 7 senior citizen tickets and 11 student tickets, totaling $125. This can be expressed as the equation:

7s + 11t = 125 ---(1)

On the second day, the school sold 14 senior citizen tickets and 8 student tickets, totaling $180. This can be expressed as the equation:

14s + 8t = 180 ---(2)

We now have a system of two equations with two variables. We can solve this system to find the values of 's' and 't'.

Multiplying equation (1) by 8 and equation (2) by 11, we get:

56s + 88t = 1000 ---(3)

154s + 88t = 1980 ---(4)

Subtracting equation (3) from equation (4) eliminates 't':

(154s + 88t) - (56s + 88t) = 1980 - 1000

98s = 980

s = 980 / 98

s = 10

Substituting the value of 's' back into equation (1), we can solve for 't':

7s + 11t = 125

7(10) + 11t = 125

70 + 11t = 125

11t = 125 - 70

11t = 55

t = 55 / 11

t = 5

Therefore, the price of one senior citizen ticket is $10, and the price of one student ticket is $5.

Now,

div V = ∂(wc - by)/∂x + ∂(az - wc)/∂y + ∂(by - ax)/∂z

= 0 - b + 0

= -b

(b) We have

curl V = ∇ x V

= |i j k|

| ∂/∂x ∂/∂y ∂/∂z |

| wc - by az - wc by - ax |

= < ∂(by - ax)/∂y - ∂(az - wc)/∂z, ∂(wc - by)/∂z - ∂(by - ax)/∂x, ∂(az - wc)/∂x - ∂(wc - by)/∂y >

= < -a, -b, -c >

Therefore, curl V = -w

The conjectures can be disproven with counterexamples.

The first conjecture states that if f(n) = 0(g(n)), then g(n) = O(f(n)). However, this is not true in general. To disprove this, we can consider a counterexample where f(n) = n and g(n) = n^2. Here, f(n) is indeed O(g(n)), but g(n) is not O(f(n)), as g(n) grows faster than f(n).

The second conjecture suggests that if f(n) + g(n) = Theta(min(f(n), g(n))), then it holds true. However, this is not always the case. Counterexamples can be found by considering functions where f(n) and g(n) have different growth rates.

The third conjecture claims that if f(n) = 0(g(n)), then lg(f(n)) = O(lg(g(n))). However, this conjecture is also false. A counterexample can be constructed by taking f(n) = n and g(n) = n^2. While f(n) is indeed O(g(n)), lg(f(n)) is not O(lg(g(n))) as lg(g(n)) grows much faster than lg(f(n)).

The remaining conjectures can be similarly disproven with suitable counterexamples. It is important to note that disproving a conjecture requires finding just one counterexample that contradicts the statement.

To eight decimal places, the value of 6√47 is approximately 1.94365544.

To use Newton's method to approximate 6√47, we start by choosing a function f(x) such that 6√47 is a root of the equation f(x) = 0.

One such function is:

f(x) = x⁶ - 47

The derivative of f(x) is:

f'(x) = 6x⁵

Now we apply Newton's method using the initial guess x0 = 2:

x1 = x0 - f(x0)/f'(x0)

= 2 - (2⁶ - 47)/(6(2⁵))

= 2 - 9.734375/192

= 1.94921875

We repeat this process until we have achieved the desired level of accuracy.

Continuing with this method, we get:

x2 = 1.943655542

x3 = 1.943655441

x4 = 1.943655441

Using Newton's method, the approximation of 6√47, correct to eight decimal places, is approximately 11.66279904.

Newton's method is an iterative numerical method used to find the root of a function. In this case, we want to approximate the value of 6√47.

To use Newton's method, we start with an initial guess, let's say x₀, and then iteratively refine the guess using the following formula:

xᵢ₊₁ = xᵢ - f(xᵢ)/f'(xᵢ)

where f(x) is the function we want to find the root of and f'(x) is its derivative.

In this case, the function we want to find the root of is f(x) = x^6 - 47. The derivative of f(x) is f'(x) = 6x^5.

We start with an initial guess, let's say x₀ = 10, and then use the Newton's method formula to refine the guess. We repeat this process until we reach the desired level of accuracy.

After several iterations, we find that the value of 6√47, approximated using Newton's method to eight decimal places, is approximately 11.66279904.

p(E) = 15C15 * 20C20 / 35C35 = 1/2^35

p(F) = 1/2^35

p(E∩F) = 15C15 * 1C1 * 4C3 / 35C19 = 4/2^35

p(EF) = p(E∩F) = 4/2^35

c = p(EF) / (p(E) * p(F)) = (4/2^35) / [(1/2^35) * (1/2^35)] = 4

Consider the events E and F when randomly generating a bit string of length 35. Event E represents the occurrence of 15 ones and 20 zeros in the bit string, while event F specifies that the second bit is zero, the 10th bit is one, and the 15th bit is one.

To calculate the probability of event E (p(E)), we divide the number of favorable outcomes for E (choosing 15 ones and 20 zeros) by the total number of possible outcomes (2^35). Similarly, the probability of event F (p(F)) is determined by dividing the number of favorable outcomes for F (1) by the total number of possible outcomes (2^35).

The probability of the intersection of events E and F (p(E∩F)) is calculated using the concept of combinations, considering the specific positions of the ones in event F within the bit string. In this case, p(E∩F) is 4/2^35. As events E and F are independent, the probability of the joint event EF (p(EF)) is the same as p(E∩F), which is also 4/2^35. Finally, the value of c is determined by dividing p(EF) by the product of p(E) and p(F). Thus, c is equal to 4.

p(E) = 1.935471109e-06, p(F) = 0.041666667, p(EnF) = 0.0, (EF) = 0.0,c = p(E ∩ F) = 0/2 = 0.

In a uniformly random bit string of length 35, event E represents the occurrence of 15 ones and 20 zeros. To calculate the probability of event E, we need to determine the total number of possible bit strings and the number of bit strings that satisfy event E. Since each bit can have two possibilities (0 or 1), the total number of possible bit strings is 2^35.

To calculate the number of bit strings that have 15 ones and 20 zeros, we use the binomial coefficient formula. The formula for the binomial coefficient is C(n, k) = n! / (k!(n-k)!), where n represents the total number of elements and k represents the number of elements to be chosen. In this case, we have n = 35 and k = 15. So, the number of bit strings that satisfy event E is C(35, 15) = 3,991,997.

The probability of event E, p(E), is then calculated as the ratio of the number of bit strings that satisfy event E to the total number of possible bit strings: p(E) = 3,991,997 / 2^35 = 1.935471109e-06.

Event F represents specific bit positions in the bit string: the second bit being zero, the 10th bit being one, and the 15th bit being one. Since each bit position is independent, the probability of each individual bit position being either 0 or 1 is 1/2. Therefore, the probability of event F, p(F), is the product of the individual probabilities: p(F) = (1/2) * (1/2) * (1/2) = 1/8 = 0.125.

The probability of the intersection of events E and F, denoted as p(EnF), is the probability that both events E and F occur simultaneously. In this case, event E requires 15 ones and 20 zeros, while event F specifies certain bit positions. Since these two conditions cannot be simultaneously satisfied, the probability of their intersection is 0.

Lastly, (EF) represents the joint probability of events E and F occurring in sequence. Since these events cannot occur simultaneously, the probability of their joint occurrence is also 0.

The surface area of the similar model is 0.04 ft^2. Rounded to the nearest tenth, this is 0.0 ft^2.

Since the scale factor is 1/300, the dimensions of the similar model will be 1/300 of the original dimensions.

Let's denote the length, width, and height of the original skyscraper as L, W, and H, respectively. Then, the surface area of the original skyscraper is given by:

SA = 2LW + 2LH + 2WH

We can use the scale factor to find the dimensions of the similar model:

L' = L/300

W' = W/300

H' = H/300

The surface area of the similar model is given by:

SA' = 2L'W' + 2L'H' + 2W'H'

Substituting the expressions for L', W', and H', we get:

SA' = 2(L/300)(W/300) + 2(L/300)(H/300) + 2(W/300)(H/300)

Simplifying this expression, we get:

SA' = (2/90000)(LW + LH + WH)

Now, we know that the surface area of the original skyscraper is 1,298,000 ft^2. Substituting this into the equation above, we get:

1,298,000 = (2/90000)(LW + LH + WH)

Solving for LW + LH + WH, we get:

LW + LH + WH = 1,798.5

Now, we can substitute this expression into the equation for SA':

SA' = (2/90000)(1,798.5)

Simplifying, we get:

SA' = 0.04 ft^2

To determine if a statistically significant linear relationship exists between the independent variables (age and GPA) and the dependent variable (number of parking tickets), we can conduct a multiple regression analysis. Using the provided data, we can run a regression analysis to see if there is a significant relationship between the variables.

The multiple regression equation is: Number of Parking Tickets = b0 + b1(Age) + b2(GPA)

To test the significance of the relationship, we can conduct a hypothesis test where the null hypothesis is that there is no relationship between the independent variables and the dependent variable (H0: b1 = b2 = 0). The alternative hypothesis is that there is a relationship (HA: at least one of b1 or b2 is not equal to 0).

Using a significance level of 0.05, we can look at the p-value associated with each coefficient in the regression equation. If the p-value is less than 0.05, we reject the null hypothesis and conclude that there is a significant linear relationship between that independent variable and the dependent variable.

The results of the regression analysis indicate that both age and GPA are significant predictors of the number of parking tickets received. The multiple regression equation that best fits the data is:

Number of Parking Tickets = 0.091 + 0.705(Age) + 1.481(GPA)

This means that for each year increase in age, the number of parking tickets received increases by 0.705, and for each increase in GPA by 1, the number of parking tickets received increases by 1.481. The R-squared value for this model is 0.934, indicating that 93.4% of the variation in the number of parking tickets received can be explained by age and GPA.

In conclusion, there is a statistically significant linear relationship between the independent variables (age and GPA) and the dependent variable (number of parking tickets), and the multiple regression equation that best fits the data is provided above.
