find an inverse of a modulo m for the following pairs (whenever possible) a=your day of birth,m=your month of birth a=34,m=91

Answers

The inverse of 'a' modulo 'm' is not possible for the given pairs (your day and month of birth: a=34, m=91) because 'a' and 'm' are not relatively prime.

To find the inverse of 'a' modulo 'm', we need to determine a number 'x' such that (a * x) % m = 1. This means that 'x' is the multiplicative inverse of 'a' modulo 'm'. However, for an inverse to exist, 'a' and 'm' must be relatively prime, meaning they do not have any common factors other than 1. In the given pair (a=34, m=91), 'a' and 'm' share a common factor of 13. Therefore, an inverse does not exist.

When 'a' and 'm' are not relatively prime, there is no integer 'x' that satisfies the equation (a * x) % m = 1. In this case, we cannot find the inverse of 'a' modulo 'm'. It is important to note that for an inverse to exist, 'm' must be a positive integer greater than 1, and 'a' must be a positive integer less than 'm'. In the given pair (34, 91), both conditions are met, but the lack of relative primality between 'a' and 'm' prevents the existence of an inverse.

Kelly draws a rectangle. How many square corners does Kelly's rectangle have?


Choose the answer that makes the statement true. Kelly's rectangle has

Choose. Square corners

Answers

Kelly's rectangle has four square corners.

A rectangle is a quadrilateral with four sides and four angles. In a rectangle, opposite sides are equal in length, and all angles are right angles (90 degrees). A square is a special type of rectangle where all sides are equal in length

. Since a square is a type of rectangle, it also has four right angles, making all its corners square corners. Therefore, Kelly's rectangle, which is not specified as a square, may have different side lengths, but it will still have four right angles, resulting in four square corners.

These corners are formed by the intersection of the sides at right angles, creating a shape with sharp, 90-degree angles. So, regardless of the specific dimensions of Kelly's rectangle, it will always have four square corners.

6.5.3 if (x1, . . . , xn) is a sample from a pareto(α) distribution (see exercise 6.2.9), whereα > 0 is unknown, determine the fisher information.

Answers

The Fisher information for a sample of size n from a Pareto(α) distribution is n/(α^2).

The Fisher information for a Pareto(α) distribution is I(α) = nα² / (α - 1)².

To determine the Fisher information for a sample from a Pareto(α) distribution, follow these steps:

1. Recall the Pareto(α) probability density function (PDF): f(x) = αxᵃ⁺¹), where x ≥ 1 and α > 0.
2. Compute the log-likelihood function, L(α) = ln(f(x1,...,xn)) = ∑ ln(α) - (α+1)ln(xi) for i = 1 to n.
3. Differentiate L(α) with respect to α: dL/dα = ∑ (1/α) - ln(xi).
4. Differentiate dL/dα again: d²L/dα² = -∑ (1/α²).
5. The Fisher information is the negative expectation of the second derivative: I(α) = -E(d²L/dα²).
6. Apply the Pareto(α) distribution's expectation: I(α) = nα² / (α - 1)².

Panchito discovered a refreshing beverage by mixing a 5% cranberry juice with a 90% orange juice. How much of each should he mix together to make 150 ml of a 22% cranberry-orange juice blend

Answers

Panchito should mix 30 ml of cranberry juice with 120 ml of orange juice to make 150 ml of a 22% cranberry-orange juice blend.

To determine the amounts of cranberry juice and orange juice that Panchito should mix, we can set up a system of equations based on the given information. Let's assume Panchito mixes x ml of cranberry juice and y ml of orange juice.

The total volume of the mixture is 150 ml: x + y = 150.

The percentage of cranberry juice in the mixture is 22%: (0.05x) / 150 = 0.22.

Simplifying the second equation, we get:

0.05x = 0.22 * 150

0.05x = 33

x = 33 / 0.05

x = 660 ml

Substituting this value back into the first equation, we can solve for y:

660 + y = 150

y = 150 - 660

y = -510 ml

Since the solution for y is negative, it is not feasible. This indicates that there is no way to create a 22% cranberry-orange juice blend using a 5% cranberry juice and a 90% orange juice.

We say XA is an indicator variable for event A: XA = 1 if A occurs, XA = 0 if A does not occur. If P(A) = 0.35, what is: • E(XA)? Var (XA)

Answers

The expected value of XA is 0.35, and the variance of XA is 0.2275.

To find the expected value of XA, we simply multiply the probability of A occurring (0.35) by 1 (the indicator variable when A occurs) and add the product of the probability of A not occurring (1 - 0.35 = 0.65) and 0 (the indicator variable when A does not occur). So, E(XA) = 0.35 * 1 + 0.65 * 0 = 0.35.

To find the variance of XA, we need to calculate the probability of each outcome (0 or 1) and its squared difference from the expected value. The variance formula for an indicator variable is Var(XA) = P(A)(1 - P(A)). Therefore, Var(XA) = 0.35 * (1 - 0.35) = 0.35 * 0.65 = 0.2275.

(Simplify your answer. Type your answer in interval notation.)

Answers

B. sigma^infinity_k = 0 x^k + 3, and the interval of convergence is (-1, 1).

To find the power series representation for g(x), we need to rewrite g(x) in terms of the given geometric series.

Notice that g(x) can be written as:
g(x) = x^3/1 - x = x^3 * (1/1-x)

We can now substitute the formula for the geometric series to get:

g(x) = x^3 * sigma^infinity_k = 0 x^k
= sigma^infinity_k = 0 (x^3 * x^k)
= sigma^infinity_k = 0 x^(k+3)

Therefore, the power series representation for g(x) is:
sigma^infinity_k = 0 x^(k+3)

The interval of convergence of this series is the same as that of the geometric series, which is |x| < 1.

In interval notation, this can be written as (-1, 1).

Therefore, the correct answer is B. sigma^infinity_k = 0 x^k + 3, and the interval of convergence is (-1, 1).

this function assumes that the baseball is thrown from ground level, and it does not take into account any external factors that may affect the trajectory of the ball (such as air resistance, wind, or spin).

Assuming that air resistance can be ignored, the height (in feet) of a baseball thrown upward with an initial velocity of 30 ft/s at time t (in seconds) can be modeled by the function:

Step-by-step explanation:

is a square, all sides congruent, we add up and we have the perimeter

Perimeter = 4 + 4 + 4 + 4 = 16 m

Answer:

The result of the perimeter is 16 meters (m).

Step-by-step explanation:

To solve, we must first know that the perimeters in this problem should only be added to each side, which is 4, where it gives a result of 16 meters (m).

¿What are the perimeters?

First of all we must know that in geometry, the perimeter is the sum of all the sides. A perimeter is a closed path that encompasses, surrounds, or skirts a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.

With this we can say that the perimeters are those that are added from each side, so, what we need to do in this problem is just just add each side, each side is four, so we can add it by 4 since it asks us for that.

[tex] \bold{4 + 4 + 4 + 4 = \boxed{ \bold{16m}}}[/tex]

But we also have another step to solve this problem, which is just squaring it where it also gives us the same result, let's see:

[tex] \bold{2 {}^{4} = \boxed{ \bold{16 \: meters \: (m)}}}[/tex]

So, as we see, each resolution gives us the same result, therefore, the result of the perimeter is 16 meters (m).

The intersection over the indexed family {A_i} is nonempty, as there are no elements that belong to all three sets:
⋂(A_i) = A_1 ∩ A_2 ∩ A_3 = ∅ (empty set)

An indexed family of sets that is pairwise disjoint but has a nonempty intersection can be represented as follows:

Consider an indexed family of sets {A_i} where i belongs to the index set I, with I = {1, 2, 3}. Define the sets A_i as:

A_1 = {1, 2}
A_2 = {2, 3}
A_3 = {1, 3}

The sets are pairwise disjoint since no two sets share any common elements:
A_1 ∩ A_2 = {2} (not empty)
A_1 ∩ A_3 = {1} (not empty)
A_2 ∩ A_3 = {3} (not empty)

However, the intersection over the indexed family {A_i} is nonempty, as there are no elements that belong to all three sets:

⋂(A_i) = A_1 ∩ A_2 ∩ A_3 = ∅ (empty set)

Answers

The answer is option 13. 4 square centimeters.

Let's first find the length of the sides of each triangle. Since the perimeter of each triangle is 10 centimeters, and each triangle has 3 sides of equal length, the length of each side of the triangles is given by;

Side length = Perimeter ÷ Number of sides

= 10 ÷ 3= 3.33 (rounded to 2 decimal places)

The base of each triangle measures 2 centimeters, and the length of the side is 3.33 centimeters.

We can use the Pythagorean theorem to find the height of the triangles. Using Pythagorean theorem,

a² + b² = c²where a = 1, b = h and c = 3.33

From the formula above, we can find that:

h² = c² - a²

= 3.33² - 1²

≈ 10.77h

≈ √10.77

≈ 3.28

The area of each triangle is given by the formula;

Area = 1/2 x base x height

= 1/2 x 2 x 3.28

= 3.28 square centimeters (rounded to 2 decimal places)

Since there are 4 triangles, the total area of the plastic triangles on the spinner is approximately:

Total area = 4 x 3.28

= 13.12 square centimeters (rounded to 2 decimal places)

Use the limit comparison test to determine if the series converges or diverges. 29) ∑n=1[infinity]​9n3/2−10n−34n

Answers

The series converges based on the limit comparison test.

To determine whether the given series converges or diverges, we can apply the limit comparison test. The limit comparison test states that if the limit of the ratio between the given series and a known convergent series is a finite positive value, then the given series converges. If the limit is zero or infinite, the given series diverges.

Let's consider the series ∑(9n^(3/2) - 10n - 34n) from n = 1 to infinity.

To apply the limit comparison test, we need to find a known convergent series to compare it with. A good choice is the p-series ∑(1/n^p), where p > 0.

Now, let's find the limit of the ratio of the two series:

lim(n→∞) [(9n^(3/2) - 10n - 34n) / (1/n^(3/2))]

= lim(n→∞) [(9n^(3/2) - 10n - 34n) * (n^(3/2))]

= lim(n→∞) [9n^3 - 10n^(5/2) - 34n^(5/2)]

To simplify the expression, divide all terms by n^(5/2):

= lim(n→∞) [(9n^3 / n^(5/2)) - (10n^(5/2) / n^(5/2)) - (34n^(5/2) / n^(5/2))]

= lim(n→∞) [9n^(3 - 5/2) - 10 - 34]

= lim(n→∞) [9n^(1/2) - 10 - 34]

= lim(n→∞) [9n^(1/2) - 44]

Since the limit is a finite value (-44), the ratio converges. Therefore, by the limit comparison test, the given series ∑(9n^(3/2) - 10n - 34n) converges.

How to Find the Kind of Roots of an Equation?

To determine the number and kind of roots of the equation f(x) = x³ - x² - x + 1, we can analyze the discriminant of the equation.

The discriminant, denoted as Δ, is given by:

Δ = b² - 4ac

In this case, the equation is in the form ax³ + bx² + cx + d = 0, where a = 1, b = -1, c = -1, and d = 1.

Calculating the discriminant:

Δ = (-1)² - 4(1)(-1)(-1) = 1 - 4(1)(1) = 1 - 4 = -3

The discriminant is negative (Δ < 0). This means that there are no real roots for the equation f(x) = x³ - x² - x + 1.

Consider two independent random variables X and Y. X has a Uniform distribution on the interval (0, 3). The probability density function of Y is given by fY (y) = y^2/9 if 0 < y < 3; 0 otherwise (a) Calculate P(X / Y > 1). (b) Calculate P(X + Y > 2). (c) Calculate P(X * Y > 3)

Answers

Answer :   ∫∫[Y > 3/X] (1/3) * (y^2/9) dx/dy.

(a) To calculate P(X/Y > 1), we need to find the probability that the ratio of X to Y is greater than 1.

The joint probability density function of X and Y, since they are independent, is given by f(X,Y) = fX(x) * fY(y).

Given that X has a Uniform distribution on (0, 3), the probability density function of X, fX(x), is:

fX(x) = 1/(3-0) = 1/3 for 0 < x < 3, and 0 otherwise.

The probability density function of Y, fY(y), is given as:

fY(y) = y^2/9 for 0 < y < 3, and 0 otherwise.

Now, we can calculate P(X/Y > 1) as follows:

P(X/Y > 1) = ∫∫[X/Y > 1] f(X,Y) dxdy

          = ∫∫[X > Y] fX(x) * fY(y) dxdy

          = ∫∫[X > Y] (1/3) * (y^2/9) dxdy

          = ∫[0,3] ∫[0,x] (1/3) * (y^2/9) dydx

          = (1/3) ∫[0,3] [(1/9) * (y^3/3)] evaluated from 0 to x dx

          = (1/3) ∫[0,3] (x^3/27) dx

          = (1/3) * [(1/108) * (x^4)] evaluated from 0 to 3

          = (1/3) * [(1/108) * (3^4 - 0^4)]

          = (1/3) * [(1/108) * 81]

          = 1/4.

Therefore, P(X/Y > 1) = 1/4.

(b) To calculate P(X + Y > 2), we need to find the probability that the sum of X and Y is greater than 2.

We can calculate this as follows:

P(X + Y > 2) = ∫∫[X + Y > 2] f(X,Y) dxdy

            = ∫∫[X > 2 - Y] fX(x) * fY(y) dxdy

            = ∫∫[X > 2 - Y] (1/3) * (y^2/9) dxdy.

To solve this integral, we can break it into two parts based on the range of Y:

For 0 < y < 2:

∫∫[X > 2 - Y] (1/3) * (y^2/9) dxdy = ∫[0,2] ∫[2-y,3] (1/3) * (y^2/9) dxdy.

For 2 < y < 3:

∫∫[X > 2 - Y] (1/3) * (y^2/9) dxdy = ∫[2,3] ∫[0,3] (1/3) * (y^2/9) dxdy.

Calculating these integrals will give us the desired probability.

(c) To calculate P(X * Y > 3), we need to find the probability that the product of X and Y is greater than 3.

Similarly, we can set up the

integral:

P(X * Y > 3) = ∫∫[X * Y > 3] f(X,Y) dxdy

            = ∫∫[Y > 3/X] fX(x) * fY(y) dxdy

            = ∫∫[Y > 3/X] (1/3) * (y^2/9) dxdy.

We can then evaluate this integral over the appropriate ranges to find the desired probability.

the proportion of variation explained by the model is called the ____group of answer choices a. slope of the line b. sum of squares error c. coefficient of determination d. coefficient of correlation

Answers

The proportion of variation explained by the model is called the coefficient of determination, also denoted as R-squared.

It is a statistical measure that represents the percentage of the variance in the dependent variable that is explained by the independent variable(s) in the regression model. In other words, it measures the goodness of fit of the regression line to the observed data points. The coefficient of determination ranges from 0 to 1, where 0 indicates that the model does not explain any of the variance in the dependent variable, and 1 indicates that the model explains all of the variance in the dependent variable. The coefficient of determination is often used in regression analysis to evaluate the predictive power of the model and to compare the fit of different models.

6. (20 points) the domain of a relation a is the set of integers. 2 is related to y under relation a it =u 2.

Answers

For any integer input x in the domain of relation a, if x is related to 2, then the output will be u2.

Based on the given information, we know that the domain of the relation a is the set of integers. Additionally, we know that 2 is related to y under relation a, with the output being u2.

Therefore, we can conclude that for any integer input x in the domain of relation a, if x is related to 2, then the output will be u2. However, we do not have enough information to determine the outputs for other inputs in the domain.

In other words, we know that the relation a contains at least one ordered pair (2, u2), but we do not know if there are any other ordered pairs in the relation.

Consider the following problem: The data set includes 107 body temperatures of healthy adult humans for which x=98.7°F and s = 0.72° F. Construct a 99% confidence interval estimate of the mean body temperature of all healthy humans. What is the appropriate symbol to use for the answer?___ < δ < ______ < µ < ______ < p < ______ < z < ______ < n < ___

Answers

The appropriate symbols to use for the answer are: µ - z * (s / √n) < δ < µ + z * (s / √n)

To construct a confidence interval estimate for the mean body temperature of all healthy humans, we can use the symbol "µ" to represent the population mean.

A 99% confidence interval estimate for the mean body temperature can be represented as:

µ - z * (s / √n) < µ < µ + z * (s / √n)

In this expression:

"z" represents the critical value from the standard normal distribution corresponding to the desired confidence level (in this case, 99%).

"s" represents the sample standard deviation.

"n" represents the sample size.

Therefore, the appropriate symbols to use for the answer are:

µ - z * (s / √n) < δ < µ + z * (s / √n)

find the area enclosed by the polar curve r=12sinθ. write the exact answer. do not round.

Answers

To find the area enclosed by the polar curve r = 12sinθ, we can use the formula for the area of a polar curve: A = 1/2 * ∫(r^2)dθ. For r = 12sinθ, the integral limits are from 0 to π because the curve covers a full period of the sine function.

Let's evaluate the integral using angle identity:

A = 1/2 * ∫(r^2)dθ
A = 1/2 * ∫((12sinθ)^2)dθ, with θ from 0 to π

A = 1/2 * ∫(144sin^2θ)dθ

Now, we can use the double angle identity sin^2θ = (1 - cos(2θ))/2:

A = 1/2 * ∫(144(1 - cos(2θ))/2)dθ

A = 72 * ∫(1 - cos(2θ))dθ, with θ from 0 to π

Now, we can integrate:

A = 72 * [θ - 1/2 * sin(2θ)] from 0 to π

A = 72 * [π - 0 - (1/2 * sin(2π) - 1/2 * sin(0))]

A = 72 * π

The exact area enclosed by the polar curve r = 12sinθ is 72π square units.

show if m is a positive integer and a is an integer relatively prime to m such that ordma = m - 1, then m is prime.

Answers

Let us assume that m is not prime. This means that there exists a prime factor p of m such that p ≤ √m. Since a is relatively prime to m, it must also be relatively prime to p.

Now, let's consider the order of a modulo p. We know that ordpa divides p-1, since p is prime. However, since a and p are relatively prime, we also know that ordpa cannot be equal to p-1, since this would imply that a is a primitive root modulo p, which is impossible since p is a prime factor of m and therefore does not have any primitive roots modulo p.
So, ordpa must divide p-1, but it cannot be equal to p-1. Therefore, ordpa must be strictly less than m-1 (since m has p as a factor, which means that m-1 has p-1 as a factor). However, we know that ordma = m-1. This means that ordpa cannot be equal to ordma.
This is a contradiction, since we assumed that ordma = m-1 and that ordpa divides m-1. Therefore, our initial assumption that m is not prime must be false. Therefore, m must be prime.
In conclusion, if m is a positive integer and a is an integer relatively prime to m such that ordma = m-1, then m must be prime.

to test this series for convergence ∑_(n=1 )^[infinity]▒n/√(n^3+4)
you could use the limit comparison test, comparing it to the series ∑_(n=1)^[infinity]▒1/n^p where p=

Answers

Using the limit comparison test by comparing it to the series ∑(n=1 to ∞) 1/n^p, for convergence where p is a positive constant if p > 1, the series ∑(n=1 to ∞) n/√(n^3 + 4) converges. Otherwise, it diverges.

Let's determine the value of p to compare the given series:

Taking the limit as n approaches infinity of the ratio between the terms of the two series:

lim(n→∞) (n/√(n^3 + 4)) / (1/n^p)

Simplifying the expression inside the limit:

lim(n→∞) (n/n^p) / √(n^3 + 4)

Taking the reciprocal of the denominator:

lim(n→∞) (n/n^p) * (1/√(n^3 + 4))

Now, let's simplify further by dividing both the numerator and denominator by n:

lim(n→∞) 1/n^(p-1) * (1/√(n^2 + 4/n))

Since the term 4/n approaches 0 as n approaches infinity, we have:

lim(n→∞) 1/n^(p-1) * (1/√n^2)

Simplifying inside the limit:

lim(n→∞) 1/n^(p-1) * (1/n)

Combining the terms:

lim(n→∞) 1/n^p

For the series to converge, the limit above must be finite and positive.

Let's analyze the cases for p:

If p > 1:

In this case, the limit is 0, indicating that the series ∑(n=1 to ∞) 1/n^p converges. Therefore, the given series ∑(n=1 to ∞) n/√(n^3 + 4) also converges.

If p ≤ 1:

In this case, the limit approaches infinity, indicating that the series ∑(n=1 to ∞) 1/n^p diverges. Therefore, the given series ∑(n=1 to ∞) n/√(n^3 + 4) also diverges.

In conclusion, if p > 1, the series ∑(n=1 to ∞) n/√(n^3 + 4) converges. Otherwise, it diverges

came out to $89.25 before tax and tip.
If tax is 6% and tip is 15%, what is
the total cost?

Answers

Answer:

$108.80

Step-by-step explanation:

89.25x0.06 = $5.36 tax

89.25 + 5.36= 94.61

94.61 x 0.15 = 14.91 tip

94.61 + 14.91 = 108.80 total

A faster way: 89.25*1.06*1.15=108.80

Your tax is going to be $5.36 bringing your total to $94.61. If you tip on pretax total your tip will be $13.39. (Total will be $102.64) If you tip on the taxed total the tip will be $14.19 bringing the total to $103.44
