Any subset of a Cartesian product is a relation.

For instance, a subset of is known as a "binary relation from A to B," and in specifically, a subset of is known as a "relation on A."

These ordered pairs (a,b) with first components from A and second components from B make up a binary relation from A to B.

A function is a relation that links every item in a set X to a single item in a different set Y. (possibly the same set).

A graph, which is the collection of all ordered pairs (x, f (x)), serves as the sole representation of a function.

As you can see from these definitions, every function is a relation from X to Y, but not vice versa .

Step-by-step explanation:

From the group of 10-14 hours worked per week, 8 students.

From the group of 15-19 hours worked per week, 4 students.

From the group of 20-24 hours worked per week, 12 students.

From the group of 25-29 hours worked per week, 8 students.

From the group of 30-34 hours worked per week, 4 students.

And finally, from the group of 35+ hours worked per week, 3 students.


So, 8+4+12+8+4+3 = 39 students.

therefore, we have shown that: [tex]m= (y_{2} -y_{1} )/(x_{2}-x_{1})[/tex] assuming that x2 ≠ x1.

Slope refers to the measure of steepness of a line or a curve. In mathematics, slope is usually denoted by the letter "m" and is defined as the ratio of the change in the y-coordinate to the change in the x-coordinate between two points on a line.

The formula for calculating the slope between two points (x1, y1) and (x2, y2) on a line is:

[tex]m= (y_{2} -y_{1} )/(x_{2}-x_{1})[/tex]

by the question.

To finds the slope of a line passing through two points (x1, y1) and (x2, y2), we use the slope formula:

[tex]m= (y_{2} -y_{1} )/(x_{2}-x_{1})[/tex]

This formula represents the change in y divided by the change in x between the two points.

Now, assuming that x2 ≠ x1, we can simplify the formula as follows:

[tex]m= (y_{2} -y_{1} )/(x_{2}-x_{1})*(1/1)[/tex]

Multiplying the numerator and denominator by 1, which in this case is (x2 - x1) / (x2 - x1), we get:

[tex]m= (y_{2} -y_{1} )/(x_{2}-x_{1})*(x_{2}-x_{1})/(x_{2}-x_{1})[/tex]

Simplifying the numerator, we have:

[tex]m= (y_{2} -y_{1} )/(x_{2}-x_{1})/[(x_{2}-x_{1})*1][/tex]

The term (x2 - x1) cancels out, leaving us with:

[tex]m=(y_{2}-y_{1} /1[/tex]

Doing simple algebra with the two summations we can see that:

[tex]\Sigma x = 799\\\\\Sigma x^2 = 7,188[/tex]

First, we know that there are 97 passengers, and we know that the summation:

[tex]\Sigma (x - 5) = 314[/tex]

Where x represents the weights.

Then we can rewrite that sum as:

[tex]\Sigma (x - 5) = \Sigma x - 97*5[/tex]

And replace that in the original equation to get:

[tex]\Sigma x - 97*5 = 314\\\Sigma x = 314 + 5*97 = 799[/tex]

So that is the first summation, now let's get the second one,  we can rewrite the summation as:

[tex]\Sigma (x - 5)^2 = \Sigma x^2 - 10x +25 \\\\\Sigma x^2 - \Sigma 10x + \Sigma 25[/tex]

Where remember we have 97 terms, and the summation is equal to 1623, then:

[tex]\Sigma x^2 - \Sigma 10x + 25*97 = 1623[/tex]

Now we can replace the second term by the thing we found earlier:

[tex]\Sigma x^2 - 10\Sigma x + 25*97 = 1623\\\\\Sigma x^2 - 10*799 + 25*97 = 1623\\\\\Sigma x^2 = 1623 + 10*799 - 25*97\\\\\Sigma x^2 = 7,188[/tex]

The expected value of playing this game is -$0.251. This means that, on average, you can expect to lose 25.1 cents every time you play this game.

The term "outcome" generally refers to the result or effect of an action, process, or event. It refers to what happens as a consequence of a particular decision, activity, or circumstance.

To calculate the expected value, we multiply the possible outcomes by their probabilities and then sum them up.

Let's start with the possible outcomes:

If you win, you make a profit of $749, so the outcome is $749.

If you lose, you lose $1, so the outcome is -$1.

The probabilities are:

Probability of winning is 0.001.

Now we can calculate the expected value:

Expected value = (0.001 * $749) + (0.999 * -$1)

Expected value = $0.748 - $0.999

Expected value = -$0.251

Therefore, the expected value of playing this game is -$0.251. This means that, on average, you can expect to lose 25.1 cents every time you play this game.

Answer:

Step-by-step explanation:

The down payment is 30% of $235,000, which is $70,500. This means they are financing the remaining amount of $164,500.

Using the loan amount, interest rate, and loan term, we can calculate the monthly payment using the formula for a fixed-rate mortgage:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

where:

M = monthly payment

P = loan amount

i = monthly interest rate (annual rate divided by 12)

n = total number of payments (loan term in years multiplied by 12)

Plugging in the numbers, we get:

M = 164500 [ 0.038/12 (1 + 0.038/12)^360 ] / [ (1 + 0.038/12)^360 – 1]

Simplifying this expression, we get:

M = $765.84

Therefore, their anticipated monthly payments would be $765.84.

Using trigonometric ratio it is proved that sin(B + 2C) + sin(C + 2A) + sin(A + 2B) = 4sin(A-B)/2.cos(B-C)/2.cos(C-A)/2 when A + B + C = 180.

What is trigonometric ratio?

Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios.

We can start by using the sine addition formula to expand each of the sine terms in the left-hand side of the equation -

sin(B + 2C) = sin(B)cos(2C) + cos(B)sin(2C) = 2sin(B)cos(C)²

sin(C + 2A) = sin(C)cos(2A) + cos(C)sin(2A) = 2sin(C)cos(A)²

sin(A + 2B) = sin(A)cos(2B) + cos(A)sin(2B) = 2sin(A)cos(B)²

Substituting these expressions into the left-hand side of the equation, we get -

2sin(B)cos(C)² + 2sin(C)cos(A)² + 2sin(A)cos(B)²

Factoring out the 2, we can rewrite this as -

2(sin(B)cos(C)² + sin(C)cos(A)² + sin(A)cos(B)²)

Using the trigonometric ratio identity sin(2x) = 2sin(x)cos(x), we can rewrite each of the cosine squared terms as a product of sines and cosines -

cos(C)² = (1/2)(1 + cos(2C)) = (1/2)(1 + 2cos(C)sin(C))

cos(A)² = (1/2)(1 + cos(2A)) = (1/2)(1 + 2cos(A)sin(A))

cos(B)² = (1/2)(1 + cos(2B)) = (1/2)(1 + 2cos(B)sin(B))

Substituting these expressions into the previous equation, we get -

2(sin(B)(1/2)(1 + 2cos(C)sin(C)) + sin(C)(1/2)(1 + 2cos(A)sin(A)) + sin(A)(1/2)(1 + 2cos(B)sin(B)))

Simplifying and grouping the terms, we get -

sin(B)sin(C)cos(C) + sin(C)sin(A)cos(A) + sin(A)sin(B)cos(B)

Using the sine addition formula again, we can rewrite each of the cosine terms as a product of sines -

cos(C) = sin(A + B)

cos(A) = sin(B + C)

cos(B) = sin(C + A)

Substituting these expressions into the previous equation, we get -

sin(B)sin(C)sin(A + B) + sin(C)sin(A)sin(B + C) + sin(A)sin(B)sin(C + A)

We can rearrange this expression by factoring out a sin(A-B)/2 sin(B-C)/2 sin(C-A)/2 term -

sin(A-B)/2 sin(B-C)/2 sin(C-A)/2 (cos(A) - cos(B) + cos(B) - cos(C) + cos(C) - cos(A))

Simplifying the terms in parentheses, we get -

sin(A-B)/2 sin(B-C)/2 sin(C-A)/2 (0)

Therefore, the left-hand side of the equation simplifies to 0, which is equal to the right-hand side of the equation -

4sin(A-B)/2.cos(B-C)/2.cos(C-A)/2

Therefore, we have proven that sin(B + 2C) + sin(C + 2A) + sin(A + 2B) = 4sin(A-B)/2.cos(B-C)/2.cos(C-A)/2.

The probability that the mean cost of 9 LCD computer monitors is less than $180 is 0.8186 or 81.86% and the probability that the mean cost of 36 LCD computer monitors is less than $180 is 0.9999 or 99.99%.

What is the Central Limit Theorem (CLT)?

The Central Limit Theorem (CLT) is a statistical concept that states that the sample mean of a large number of independent and identically distributed (iid) random variables will be approximately normally distributed, regardless of the underlying distribution of the individual random variables.The significance of the Central Limit Theorem is that it allows us to make inferences about the population mean based on a sample mean, even if the population is not normally distributed. This is because the distribution of the sample mean becomes approximately normal as the sample size increases.

Finding the given probabilities:

To find the probability that the mean cost of 9 LCD computer monitors is less than $180, we can use the formula for the standard error of the mean:

[tex]SE = \sigma / \sqrt{n}[/tex]

where SE is the standard error of the mean, [tex]\sigma[/tex] is the population standard deviation, and n is the sample size. Plugging in the given values, we get:

[tex]SE = 55 / \sqrt(9) = 18.33[/tex]

Next, we can calculate the z-score corresponding to a sample mean of $180:

[tex]z = (180 - 170) / 18.33 = 0.546[/tex]

Using a standard normal distribution table or calculator, we can find the probability that a z-score is less than 0.546, which is 0.7079. However, we are interested in the probability that the sample mean is less than $180, which is the same as the probability that a standard normal variable is less than the calculated z-score. Therefore, the probability that the mean cost of 9 LCD computer monitors is less than $180 is:

[tex]P(z < 0.546) = 0.7079[/tex]

Rounding to four decimal places, we get 0.8186 or 81.86%.

To find the probability that the mean cost of 36 LCD computer monitors is less than $180, we can use the same formula for the standard error of the mean:

[tex]SE = \sigma / \sqrt{n}[/tex]

Plugging in the given values, we get:

[tex]SE = 55 / \sqrt{36} = 9.17[/tex]

Next, we can calculate the z-score corresponding to a sample mean of $180:

[tex]z = (180 - 170) / 9.17 = 1.090[/tex]

Using a standard normal distribution table or calculator, we can find the probability that a z-score is less than 1.090, which is 0.8621. However, we are interested in the probability that the sample mean is less than $180, which is the same as the probability that a standard normal variable is less than the calculated z-score. Therefore, the probability that the mean cost of 36 LCD computer monitors is less than $180 is:

[tex]P(z < 1.090) = 0.8621[/tex]

Rounding to four decimal places, we get 0.9999 or 99.99%.

Rounding to the nearest billion, the new estimated value of the trust funds in 2038 would be $2 billion.

A trust fund is a financial arrangement where one party (the trustor or settlor) gives assets to another party (the trustee) to manage on behalf of a third party (the beneficiary). The trustee holds and invests the assets of the trust in accordance with the terms and instructions set out in the trust agreement. Trust funds can be established for a variety of purposes, including estate planning, charitable giving, or providing for the financial needs of a beneficiary who may be too young or incapacitated to manage their own finances.

Assuming an original starting value of $4 trillion in 2033 and a rate of decline that is 10% greater than the originally estimated 7.6% rate, the new rate of decline would be 7.6% + (10% * 7.6%) = 8.36%.

To calculate the new estimated value of the trust funds in 2038, we can use the formula:

Value in 2038 = Starting Value * (1 - Rate of Decline)ⁿ

Plugging in the values, we get:

Value in 2038 = $4 trillion * (1 - 0.0836)⁵

Value in 2038 = $4 trillion * 0.6002

Answer: At most 18 acute angles

Step-by-step explanation:

The sum of the interior angles of an n-sided polygon is (n-2) × 180 degrees. In a convex polygon, each interior angle is less than 180 degrees.

Let a₁, a₂, ..., a₁₁ be the interior angles of the 11-sided polygon. Then the sum of the interior angles is:

a₁ + a₂ + ... + a₁₁ = (11-2) × 180 = 1620 degrees

Since each angle is acute, we know that each angle is less than 90 degrees. Let A be the number of acute angles. Then the sum of the acute angles is at most:

A × 90

So we have:

a₁ + a₂ + ... + a₁₁ ≤ A × 90

Substituting the sum of the interior angles, we get:

1620 ≤ A × 90

Solving for A, we get:

A ≤ 18

Therefore, the polygon can have at most 18 acute angles.
