Coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.
What is clockwise rotation?
" Clockwise rotation means when any object is moving in the direction of hands of clock."
According to the question,
As per the diagram ,
Coordinates of M are ( 3, 4)
Rotation of a point through 180° about the origin when a point M( x, y) is rotated about the origin through 180° in anticlockwise or clockwise direction, it takes the new coordinates ( -x ,-y).
Therefore , coordinates of M are ( -3, -4).
Hence, coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

The table shows three functions and their output values for different values of x. Which equation represents h(x)? h(x) = (f(x))(g(x)) h(x) = f(x) – g(x) h(x) = f(x) + g(x)
The equation that represents h(x) is h(x) = (f(x))(g(x)).
To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).
Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).
Let's examine the table and compare the values:
x | f(x) | g(x) | h(x)
1 | 3 | 4 | 12
2 | 5 | 2 | 10
3 | 2 | 6 | 12
From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).

Answer:
mAngleT = 60°
mAngleU = 60°
TS = 13cm
SU = 13cm
Step-by-step explanation:
Since two of the sides are the same the two base angles are also the same. One is 60° so the other one is 60° also. But if they are both 60° and all the angles add up to 180° the last one has to be 60° also.
One side is marked 13cm. It is marked congruent to the left side so they are both 13cm.
But we saw from the angles all being the same, that this is actually an equilateral triangle. So all three sides are the same.

Another common bet in roulette is on the number being even or odd (not including 0 or 00). If the wheel is spun once, what is the probability of the outcome being an odd number?
Answer:
9/19 or 47.4% (nearest tenth)
Step-by-step explanation:
A roulette wheel is numbered 1 to 36 with 0 and 00.
Therefore, there is a total of 38 evenly-spaced pockets.
The number of odd numbers from 1 to 36 is 18
(1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35)
\(\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}\)
\(\implies \textsf{Probability of odd number}= \sf \dfrac{18}{38}=\dfrac{9}{19}=47.4\%\)
Roulette wheel contains 1 to 36 numbers excluding 0 and 00

An easement enabling its holder to prevent the possessor of the land subject to the easement from doing certain acts or exercising certain rights of ownership is known as a negative easement.
A negative easement grants the holder the right to restrict or prohibit specific activities on the land, even though the possessor of the land would otherwise have the legal right to engage in those activities. It imposes limitations on the use or enjoyment of the land by the possessor.
For example, a negative easement may prohibit the landowner from building any structures that would obstruct the view of the neighboring property or from engaging in any activities that would cause excessive noise or pollution. The holder of the negative easement, such as a neighboring property owner or a conservation organization, can enforce these restrictions to protect their interests or preserve certain conditions.
Negative easements are typically established through legal agreements or by court decisions. They serve to balance the rights of the landowner with the interests of the easement holder, allowing for the protection of specific rights or conditions associated with the land.

Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
What is the rate of change of the equation from Part A?
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?

If tanx=3, find secx
(Solve for values of x between 0 and 2pi radians)
Answer:
sec(x) = sqrt(10)
Step-by-step explanation:
We know that tan(x) = 3.
Using the identity tan^2(x) + 1 = sec^2(x), we can solve for sec(x).
First, let's square both sides of the equation tan(x) = 3:
tan^2(x) = 3^2
tan^2(x) = 9
Next, we can substitute this expression for tan^2(x) into the identity:
tan^2(x) + 1 = sec^2(x)
9 + 1 = sec^2(x)
10 = sec^2(x)
Finally, we can take the square root of both sides to solve for sec(x):
sqrt(10) = sec(x)
Therefore, sec(x) = sqrt(10).

1 Consider the following system of linear equations:
x + 2y = 2, y − z = 1, 2x + 3y + z = 3
(i) Write the above system of equations as an augmented matrix.
(ii) Reduce the augmented matrix to reduced-row echelon form using appropriate row operations.
(iii) Hence determine if the system is inconsistent, has a unique solution or has infinitely many solutions. In the case that there are infinitely many solutions, express your solution in terms of one or more parameters. If the solution is unique, state the solution explicitly for x, y and z.
(i) The augmented matrix for the given system of linear equations is:
[1 2 0 2]
[0 1 -1 1]
[2 3 1 3]
(ii) To reduce the augmented matrix to reduced-row echelon form, we perform the following row operations:
R2 → R2 + (-1)*R1/2 (subtract half of R1 from R2)
R3 → R3 + (-2)*R1 (subtract twice of R1 from R3)
R3 → R3 + (-3)*R2 (subtract three times of R2 from R3)
R2 → R2/(-1) (divide R2 by -1 to make the leading entry 1)
The resulting reduced-row echelon form is:
[1 0 0 1]
[0 1 0 1]
[0 0 1 0]
(iii) The reduced-row echelon form has a leading 1 in each row and column, which indicates that the system has a unique solution. The solution is:
x = 1, y = 1, z = 0.

19) Consider The Model Yi=B0+B1Xi+B2Ziui, If You Know The Variance Of Ui Is Σi2=Σ2zi2 How Would You Estimate The Regression?
To estimate the regression in the given model Yi = B0 + B1Xi + B2Ziui, where the variance of Ui is Σi^2 = Σ(zi^2), you can use the method of weighted least squares (WLS). The weights for each observation can be determined by the inverse of the variance of Ui, that is, wi = 1/zi^2.
In the given model, Yi = B0 + B1Xi + B2Ziui, the error term Ui is assumed to have a constant variance, given by Σi^2 = Σ(zi^2), where zi represents the individual values of Z.
To estimate the regression coefficients B0, B1, and B2, you can use the weighted least squares (WLS) method. WLS is an extension of the ordinary least squares (OLS) method that accounts for heteroscedasticity in the error term.
In WLS, you assign weights to each observation based on the inverse of its variance. In this case, the weight for each observation i would be wi = 1/zi^2, where zi^2 represents the variance of Ui for that particular observation.
By assigning higher weights to observations with smaller variance, WLS gives more importance to those observations that are more precise and have smaller errors. This weighting scheme helps in obtaining more efficient and unbiased estimates of the regression coefficients.
Once you have calculated the weights for each observation, you can use the WLS method to estimate the regression coefficients B0, B1, and B2 by minimizing the weighted sum of squared residuals. This involves finding the values of B0, B1, and B2 that minimize the expression Σ[wi * (Yi - B0 - B1Xi - B2Ziui)^2].
By using the weights derived from the inverse of the variance of Ui, WLS allows you to estimate the regression in the presence of heteroscedasticity, leading to more accurate and robust results.

Suppose a random sample of 60 measurements is selected from a population with a mean of 25 and a variance of 200. Select the pair that is the mean and standard error of x.
Based on the information provided, we have a random sample of 60 measurements taken from a population with a mean (µ) of 25 and a variance (σ²) of 200.
The mean of the sample (X) will be equal to the population mean, so X = 25.
To calculate the standard error (SE) of the sample, we use the formula SE = σ / √n, where σ is the population standard deviation and n is the sample size. Since the variance is given as 200, the standard deviation (σ) is the square root of 200, which is approximately 14.14.
Now, we can calculate the standard error: SE = 14.14 / √60 ≈ 1.82.
So, the pair for the mean and standard error of x is (25, 1.82).
