Since WY is equal to XY, which is 8, the length of WY is also 8

Since quadrilateral WXYZ is a rectangle, opposite sides are congruent. This means that WY is also equal to 8.

In a rectangle, the opposite sides are parallel and congruent, and the adjacent sides are perpendicular to each other.

Given:

XZ = 2c

ZY = 6

XY = 8

We can see that XY is the diagonal of the rectangle, and it forms a right triangle with sides XY, XZ, and ZY. Using the Pythagorean theorem, we can find the length of WY.

Using the Pythagorean theorem: XY² = XZ² + ZY²

Substituting the given values: 8² = (2c)² + 6²

64 = 4c² + 36

4c² = 64 - 36

4c² = 28

c² = 28/4

c² = 7

c = √7

Since WY is equal to XY, which is 8, the length of WY is also 8.

The main answer is that more information is needed to evaluate the value of h for water at 20°C given the parameters of surface tension (y), contact angle (θ), and the distance between the plates (w). Additional information or equations are required to solve for h.

To provide a more detailed explanation, the height (h) of the fluid between the two parallel plates can be determined using the Young-Laplace equation, which relates the pressure difference across a curved liquid interface to the surface tension and curvature. However, the given information lacks the necessary details to directly calculate the value of h.

The Young-Laplace equation states that the pressure difference (ΔP) between the two sides of the curved liquid interface is equal to the product of the surface tension (y), the mean curvature (1/r1 + 1/r2), and the cosine of the contact angle (θ):

ΔP = y * (1/r1 + 1/r2) * cos(θ)

To evaluate h, one would need additional information such as the radii of curvature (r1 and r2) of the fluid meniscus, or any other relevant parameters. Without these details, it is not possible to determine the value of h for water at 20°C based solely on the given information of surface tension, contact angle, and distance between the plates.

By applying the Quadratic Formula to  the equation 12x + 9x² = 5 has two solutions: x = 1/3 and x = -5/3.

The given equation is 12x + 9x² = 5. Rearranging the equation to standard quadratic form, we have 9x² + 12x - 5 = 0. By applying the Quadratic Formula, x = (-b ± √(b² - 4ac)) / (2a), we can find the solutions for x.

For our equation, a = 9, b = 12, and c = -5. Substituting these values into the Quadratic Formula, we get:
x = (-12 ± √(12² - 4(9)(-5))) / (2(9))
  = (-12 ± √(144 + 180)) / 18
  = (-12 ± √324) / 18
  = (-12 ± 18) / 18

Simplifying further, we have two possible solutions:
x₁ = (-12 + 18) / 18 = 6 / 18 = 1/3
x₂ = (-12 - 18) / 18 = -30 / 18 = -5/3

The probability that, when chosen at random, there will be at least 2 different races in a 3-person team is 63/64.

To calculate the probability of having at least 2 different races in a 3-person team, we need to consider the possible combinations of races.

Let's assume there are 4 different races in total (A, B, C, D). We'll calculate the probability using the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

First, let's calculate the probability of having all team members from the same race. In this case, there are 4 ways to choose a race for the team, and the probability of each team member being from that race is 1/4. So the probability of having all team members from the same race is (1/4)^3 = 1/64.

Since we want the probability of at least 2 different races, we subtract the probability of all team members from the same race from 1:

1 - 1/64 = 63/64

Therefore, the probability that, when chosen at random, there will be at least 2 different races in a 3-person team is 63/64.

The expected income from the sickness lottery is $5. The expected utility from the sickness lottery is approximately 2.23. The utility from the expected income from the sickness lottery is approximately 2.24. Based on these calculations, it can be inferred that the individual is risk-averse. The actuarially fair insurance premium for full coverage is $45. The certainty equivalent, which represents the guaranteed income level that the individual would accept instead of the uncertain outcome, is $5. As a risk-averse individual, the maximum amount the person would be willing to pay to eliminate the uncertainty is $0, as the certainty equivalent already matches the expected income.

The expected income from the sickness lottery can be calculated by considering the probabilities and possible outcomes. Since there is a 10% chance of falling sick and earning $0, and a 90% chance of working and earning $50, the expected income can be computed as follows:

Expected Income = (0.10 × $0) + (0.90 × $50) = $5

To calculate the expected utility from the sickness lottery, we need to assign utility values to different income levels. Let's assume the utility function is U = √(I), where I represents income. We can now calculate the expected utility:

Expected Utility = (0.10 × √($0)) + (0.90 × √($50)) ≈ 2.23

Next, we can calculate the utility from the expected income. Using the same utility function, the utility from the expected income of $5 can be determined:

Utility from Expected Income = √($5) ≈ 2.24

Based on the calculated expected utility and utility from expected income, we can infer that the individual is risk-averse. This is because the utility from the expected income ($5) is higher than the expected utility (2.23), indicating a preference for certainty.

The actuarially fair insurance premium for full coverage can be calculated by considering the probabilities and outcomes. In this case, since there is a 10% chance of having $0 income and a 90% chance of having $50 income, the premium should be set such that the expected value of the insurance payment equals the expected loss. The actuarially fair insurance premium can be calculated as follows:

Premium = (0.10 × $0) + (0.90 × $50) = $45

The certainty equivalent is the guaranteed income level that an individual would be willing to accept instead of the uncertain outcome. In this case, as a risk-averse individual, the certainty equivalent would be the income level that provides the same utility as the uncertain income. Using the utility function U = √(I), we can calculate the certainty equivalent:

Certainty Equivalent = (Utility from Expected Income)² = (2.24)² = $5

As a risk-averse individual, the maximum amount the individual would be willing to pay to eliminate the uncertainty is equal to the difference between the expected income and the certainty equivalent. In this case, the maximum amount would be:

Maximum Amount = Expected Income - Certainty Equivalent = $5 - $5 = $0

Therefore, the individual would not be willing to pay anything to eliminate the uncertainty, as the certainty equivalent already matches the expected income.

The solution of the system of equations is D (2, -1). This can be obtained by solving the equations simultaneously and finding the values of x and y that satisfy both equations.

To solve the system of equations, we can use the method of substitution or elimination. Let's use the elimination method:

Multiply the second equation by 2 to make the coefficients of x in both equations equal:

2(x + 3y) = 2(-1)

2x + 6y = -2

Now, subtract the first equation from this modified second equation:

(2x + 6y) - (3x - 2y) = -2 - 8

2x + 6y - 3x + 2y = -10

-x + 8y = -10

Simplify the equation:

x - 8y = 10

Now, we have a new system of equations:

x - 8y = 10

3x - 2y = 8

Solving this system of equations, we find that x = 2 and y = -1. Therefore, the solution is (2, -1), which corresponds to option D.

The conjecture is that as the number of sides of an inscribed regular polygon with a radius of 1 unit increases, the area of the polygon approaches π.

In this problem, you will investigate the areas of regular polygons inscribed in circles. The question asks to make a conjecture about the area of an inscribed regular polygon with a radius of 1 unit as the number of sides increases.

As the number of sides of a regular polygon inscribed in a circle increases, the polygon becomes more similar to a circle itself. Therefore, we can conjecture that the area of the inscribed regular polygon approaches the area of the circle with the same radius.

To calculate the area of a regular polygon, we can use the formula:

Area = (1/2) x apothem x perimeter

Since the radius of the circle is 1 unit, the apothem of the inscribed regular polygon is also 1 unit.

Now, let's consider the perimeter of the inscribed regular polygon. The perimeter is the distance around the polygon, and it will increase as the number of sides of the polygon increases.

As the number of sides increases, the inscribed regular polygon becomes more similar to a circle. In a circle, the perimeter is the circumference, given by the formula:

Circumference = 2πr

Since the radius is 1 unit, the circumference of the circle is 2π.

So, as the number of sides of the inscribed regular polygon increases, the perimeter approaches 2π.

Substituting the values into the formula for the area:

Area = (1/2) x 1 x 2π

Simplifying further:

Area = π

Therefore, the conjecture is that as the number of sides of an inscribed regular polygon with a radius of 1 unit increases, the area of the polygon approaches π.

The explicit general solution of the given differential equation is [tex]$y = \pm e^{\frac{20}{49}x + \left(C + \frac{K}{\frac{49}{2}}\right)}$[/tex].

Given the differential equation [tex]$(25 - x^2) \frac{dy}{dx} = 10y$[/tex], we want to find the explicit general solution.

Rearranging the equation and separating the variables, we have:

[tex]\[(25 - x^2) \, dy = 10y \, dx\][/tex]

Dividing both sides by [tex]$y$[/tex] and multiplying by [tex]$dx$[/tex], we get:

[tex]\[(25 - x^2) \, \frac{dy}{y} = 10 \, dx\][/tex]

Integrating both sides:

[tex]\[\int (25 - x^2) \, \frac{dy}{y} = \int 10 \, dx\][/tex]

Using the power rule for integration, we have:

[tex]\[\int (25/y - x^2/y) \, dy = \int 10 \, dx\][/tex]

Integrating [tex]$(25/y)$[/tex] with respect to [tex]$y$[/tex] gives:

[tex]\[25 \int \frac{1}{y} \, dy - \int \frac{x^2}{y} \, dy = 10x + C\][/tex]

To integrate [tex]$\int \frac{x^2}{y} \, dy$[/tex], we can use [tex]$u$[/tex]-substitution with[tex]$u = x^2$[/tex]:

Let [tex]$u = x^2$[/tex], then [tex]du = 2x \, dx$.[/tex]

Thus, [tex]\int \frac{x^2}{y} \, dy = \int \frac{u}{y} \, \frac{1}{2x} \, du = \frac{1}{2} \int \frac{u}{y} \, du = \frac{1}{2} \ln|y| + K$.[/tex]

Substituting this back into the equation, we have:

[tex]\[25 \ln|y| - \frac{1}{2} \ln|y| - K = 10x + C\][/tex]

To simplify, we can write the explicit general solution as:

[tex]\[\left(\frac{49}{2} \ln|y|\right) - K = 10x + C\][/tex]

Taking the exponential of both sides:

[tex]\[|y| = e^{\frac{20}{49}x + \left(C + \frac{K}{\frac{49}{2}}\right)}\][/tex]

Since the absolute value can be either positive or negative, we have two possible solutions:

[tex]\[y = \pm e^{\frac{20}{49}x + \left(C + \frac{K}{\frac{49}{2}}\right)}\][/tex]

The null hypothesis would assume that the claimed percentage is true, while the alternative hypothesis would state that the claimed percentage is not true. The significance level will determine the threshold for rejecting the null hypothesis based on the observed data.

In hypothesis testing, the null hypothesis (H₀) represents the claim being tested, which in this case is that the percentage of blue candies is equal to a specific value. The alternative hypothesis (H₁) contradicts the null hypothesis and suggests that the claimed percentage is not true. Let's assume the claimed percentage is p. The test statistic used for comparing observed data with the null hypothesis is typically the z-score.

The next step is to determine the significance level, denoted as α. This value represents the probability of rejecting the null hypothesis when it is true. Commonly used significance levels are 0.05 (5%) and 0.01 (1%). Once the significance level is chosen, a critical region is established, which defines the range of values that would lead to rejecting the null hypothesis. The critical region is determined based on the chosen significance level and the distribution of the test statistic (in this case, the standard normal distribution).

Finally, the observed data is collected and analyzed. The test statistic is calculated using the observed proportion of blue candies, and it is compared to the critical values. If the test statistic falls within the critical region, the null hypothesis is rejected, indicating that there is evidence to support the claim that the percentage of blue candies is different from the claimed value. If the test statistic does not fall within the critical region, the null hypothesis is not rejected, suggesting that the claim made by the candy company is plausible.

Yes the conjecture is true . The quadrilateral WXYZ is a rectangle.

Given,

Quadrilateral WXYZ .

W(-3,2), X(-3,7), Y(6,7), Z(6,2)

Now,

For the quadrilateral to be rectangle the opposite sides of the quadrilateral should be same .

So let us calculate the length of opposite sides of quadrilateral.

By distance formula,

Distance formula : √(x2 -x1)² + (y2 - y1)²

Thus the coordinates are ,

W(-3,2)

X(-3,7)

Y(6,7)

Z(6,2)

Calculate the distance between WX,

WX = 25

Distance of YZ,

YZ = 25

Distance of XY = 9

Distance of WY = 9

Thus the length of opposite sides are equal . So it is an rectangle .
