a. Method of Moments:
To find an estimator for θ using the method of moments, we equate the sample moments with the population moments.
The population moment is given by E(Y) = ∫yf(y|θ)dy. We need to find the first population moment.
E(Y) = ∫y(θ+1)y^θ dy
= (θ+1) ∫y^(θ+1) dy
= (θ+1) * (1/(θ+2)) * y^(θ+2) | from 0 to 1
= (θ+1) / (θ+2)
The sample moment is given by the sample mean: sample_mean = (1/n) * ∑Yi
Setting the population moment equal to the sample moment, we have:
(θ+1) / (θ+2) = (1/n) * ∑Yi
Solving for θ, we get:
θ = [(1/n) * ∑Yi * (θ+2)] - 1
θ = [(1/n) * ∑Yi * θ] + [(2/n) * ∑Yi] - 1
θ - [(1/n) * ∑Yi * θ] = [(2/n) * ∑Yi] - 1
θ(1 - (1/n) * ∑Yi) = [(2/n) * ∑Yi] - 1
θ = ([(2/n) * ∑Yi] - 1) / (1 - (1/n) * ∑Yi)
Therefore, the estimator for θ by the method of moments is:
θ_hat = ([(2/n) * ∑Yi] - 1) / (1 - (1/n) * ∑Yi)
b. Maximum Likelihood Estimator (MLE):
To find the maximum likelihood estimator (MLE) for θ, we need to maximize the likelihood function.
The likelihood function is given by L(θ) = ∏(θ+1)y_i^θ, where y_i represents the individual observations.
To simplify the calculation, we can take the logarithm of the likelihood function and maximize the log-likelihood instead. The log-likelihood function is given by:
ln(L(θ)) = ∑ln((θ+1)y_i^θ)
= ∑(ln(θ+1) + θln(y_i))
= nln(θ+1) + θ∑ln(y_i)
To find the maximum likelihood estimator, we take the derivative of the log-likelihood function with respect to θ and set it equal to zero:
d/dθ [ln(L(θ))] = n/(θ+1) + ∑ln(y_i) = 0
Solving for θ, we get:
n/(θ+1) + ∑ln(y_i) = 0
n/(θ+1) = -∑ln(y_i)
θ + 1 = -n/∑ln(y_i)
θ = -1 - n/∑ln(y_i)
Therefore, the maximum likelihood estimator for θ is:
θ_hat = -1 - n/∑ln(y_i)

5. Comparing Steelers in the modern NFL, teams emphasize the passing game much more than teams in the 1970s
did, which were more run-oriented. This makes it very difficult to compare the performances of quarterbacks
from these eras - even when they both played for the same team. In 1979, Terry Bradshaw threw for a career-
high 3724 yards. In 2014, Ben Roethlisberger threw for a career-high 4952 yards. 36 Whose performance was
better, relatively speaking?
a. In 1979, the top quarterback for each of the 28 teams threw for an average of 2789 yards with a
standard deviation of 752 yards. Calculate and interpret the z-score for Terry Bradshaw's performance in
1979.
b. In 2014, the top quarterback for each of the 32 teams threw for an average of 3447 yards with a standard
deviation of 970 yards. Calculate and interpret the z-score for Ben Roethlisberger's performance in 2014.k
A z-score is used to measure how many standard deviations an individual value is from the mean of a given set of data.
Whose performance was better, relatively speaking?Terry Bradshaw's performance in 1979 had a z-score of 1.21, which means his performance was 1.21 standard deviations above the mean for all quarterbacks in the NFL that year.Ben Roethlisberger's performance in 2014 had a z-score of 1.31, which means his performance was 1.31 standard deviations above the mean for all quarterbacks in the NFL that year.Terry Bradshaw's performance in 1979 had a z-score of 0.98, which indicates that his performance was slightly above average. This indicates that, while his performance was impressive in 1979, it was still slightly below what other quarterbacks in the league were doing at the time. Ben Roethlisberger's performance in 2014 had a z-score of 1.51, which indicates that his performance was significantly above average. This indicates that his performance was significantly better than what other quarterbacks in the league were doing in 2014. This is a testament to the increased emphasis on the passing game in the modern NFL.To calculate the z-score for Terry Bradshaw's performance in 1979, we subtract the mean of 2789 yards from his performance of 3724 yards and divide by the standard deviation of 752 yards. This yields a z-score of 1.95. This means that his performance was 1.95 standard deviations higher than the average of other quarterbacks in the same year. Similarly, to calculate the z-score for Ben Roethlisberger's performance in 2014, we subtract the mean of 3447 yards from his performance of 4952 yards and divide by the standard deviation of 970 yards. This yields a z-score of 1.63. This means that his performance was 1.63 standard deviations higher than the average of other quarterbacks in the same year. Therefore, while both performances were impressive, Roethlisberger's performance was slightly less impressive than Bradshaw's.To learn more about numerical value refer to:

What is the formula to find image?
The formula to find the resolution of an image, also known as its pixel density, is Pixels per Inch (PPI) or Pixels per Centimeter (PPCM). This formula is used to determine the number of pixels in a given area of an image.
The higher the PPI or PPCM, the greater the resolution of the image.
To calculate PPI, you need to know the total number of pixels in the image (width x height) and the physical size of the image (width x height in inches or cm). Once you have this information, you can use the following formula: PPI = (pixels / physical size) x (inches/cm).
For example, if an image has a resolution of 1920 x 1080 pixels and is printed at a size of 8 x 6 inches, the PPI would be (1920 x 1080) / (8 x 6) = 240 PPI.
In conclusion, PPI or PPCM is the formula used to find the resolution of an image, also known as its pixel density. It is calculated by dividing the total number of pixels in the image by its physical size and multiplying it by inches/cm.
The higher the PPI or PPCM, the greater the resolution of the image. It is important to consider the PPI or PPCM when choosing an image to print or display in order to ensure that it will be of high quality and have a high resolution.

In a tournament, a professional golfer knows that she is 200 yards from the hole. A spectator is watching her play and is 140 yards away from the golfer. Triangle with vertices labeled golfer and spectator and hole, with the distance from the golfer to the spectator measuring 140 yards and the distance from the golfer to the hole measuring 200 yards and the vertex of the spectator measuring 120 degrees If the spectator has an angle of 120° between the golfer and the hole, what is the angle that the golfer has between the spectator and the hole?
The angle that the golfer has between the spectator and the hole is cos^-1((a^2 + b^2 - c^2)/(2ab))
How do we determine the angle?The angle that the golfer has between the spectator and the hole can be found using the Law of Cosines. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the following equation holds:
c^2 = a^2 + b^2 - 2ab * cos(C)
In this case, we know that a = 140 (the distance from the golfer to the spectator), b = 200 (the distance from the golfer to the hole), and C = 120 (the angle between the golfer and the spectator).
We can use these values to solve for c, which is the distance from the spectator to the hole. Once we have this value, we can use the Law of Cosines again to find the angle between the golfer and the hole.
c^2 = 140^2 + 200^2 - 2 * 140 * 200 * cos(120)
c = sqrt(140^2 + 200^2 - 2 * 140 * 200 * cos(120))
Now we can use this value of c to find angle A:
A = cos^-1((a^2 + b^2 - c^2)/(2ab))
Note that the angle A is what we're looking for, the angle between the golfer and the hole.

The price of a suit is reduced by 20%. By what percentage must the reduced price be increased so that the new price is 12% higher than the original price? Show how to use an equation to prove your answer.
Answer:
the reduced price must be increased by 32% to have a 12% higher price than the original price
The percentage that must the reduced in the reduced price so that the new price is 12% higher than the original price is 40%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Let the price of the suit = 100
Reduced = 20%
Now,
The reduced price of the suit.
= 100 - (20% of 100)
= 100 - (20/100 x 100)
= 100 - 20
= 80 _____(1)
Now,
New price.
= 100 + (12% of 100)
= 100 + 12
= 112
Now,
From (1)
100% = 80
Multiply 112/80 on both sides.
112/80 x 100% = 112
140% = 112
This means,

The distance formula is: d = √((x2 - x1)² + (y2 - y1)²)
Let's assume that the trusses are located at point (x1, y1) and (x2, y2) and the beam is located at point (x, y).
We know that the distance between the trusses is 2 feet, so we can set d = 2.
We can use the coordinates of the trusses and the point where the beam is located to set up the equation:
d = √((x2 - x1)² + (y2 - y1)²) = 2
Since the trusses are located on the same line and only the x-coordinate changes, we can assume that y1=y2
Therefore the equation can be simplified to √((x2 - x1)²) = 2
Square both sides: (x2 - x1)² = 4
x2 - x1 = 2
Now we know that the difference between the x-coordinates of the two trusses is 2 feet.
So, to find the x-value of the point where the reinforcement beam should be placed, we can take the average of the x-coordinates of the two trusses.
x = (x1+x2)/2
We don't know the values of x1 and x2, so we can't solve for x. But we know that the reinforcement beam should be placed exactly in the middle of the trusses.
Thus, The x-value of where the beam should be placed is X = (x1+x2)/2.

Therefore , the solution of the given problem of inequality comes out to be x > 6/5 and y > -13/5.
What does inequality really mean?In mathematics, an inequality is a linear connection or a collection of numbers even when there is no equal sign. Equity always comes after equilibrium. When two numbers are not equal, inequality exists. Between equality and inequality, there exist differences. The most common symbol was chosen because when parameters aren't the same or comparable (). Values can be compared using a variety of disparities, no matter how few or numerous they are. Many fundamental inequality problems can be addressed by flipping the two aspects until only the variables are left
Here,
Given :
=> y ≤ 2x-5
=> y > -3x + 1
and
=> y ≤ 2x-5

In this right triangle, what is the length of the hypotenuse?
Answer:
hypotenuse = 55
Step-by-step explanation:
using Pythagoras' identity in the right triangle
the square on the hypotenuse c is equal to the sum of the squares on the other 2 sides, that is
c² = 33² + 44² = 1089 + 1936 = 3025 ( take square root of both sides )
c = [tex]\sqrt{3025}[/tex] = 55
How do you find the total number of factors of a number?
Total Number of Factors for N = (a+1) (b+1) (c+1) is the formula for how many factors there are in total for a given number.
what is prime factor?Any natural number other than 1 with just itself and the number 1 as its divisors is considered a prime factor. Actually, 2, 3, 5, 7, 11, and so on are some of the first prime numbers. an amount that has been multiplied to produce another amount. By dividing 15 by 3 and 5, for instance, we get 3 5 = 15. main elements: Prime factors include all factors that are prime but are not composite. A few prime factors of 30 are 2, 3, and 5. Only 2 and 3 are prime factors of 12, so listing 2 twice as 2 2 3 (or 22 3) is necessary to factorize 12. The sum of 2 + 3 is not 12.
