Solve the differential equation (Show your work). \[ 7 x^{6} \cos y d x-d y=0 \]
The solution to the given differential equation is: x⁷ cos y = y + C
where C is the constant of integration
To solve the given differential equation:
\(\[7x^6\cos y dx - dy = 0\]\)
We can separate the variables and integrate both sides.
Separating variables, we can write the equation as:
\(\[7x^6\cos y dx = dy\]\)
Now, we can integrate both sides with respect to their respective variables:
\(\[\int 7x^6\cos y dx = \int dy\]\)
Integrating the left side:
\(\[\int 7x^6\cos y dx = 7 \int x^6 \cos y dx\]\)
To integrate \(\(x^6 \cos y\)\)with respect to x, we can use integration by parts.
Let's take u = x⁶ and \(\(dv = \cos y dx\)\).
Differentiating u with respect to \(\(x\) gives \(du = 6x^5 dx\).\)
Integrating dv with respect to x gives \(\(v = \int \cos y dx = \cos y \cdot x\).\)
Applying the integration by parts formula:
\(\[\int x^6 \cos y dx = u \cdot v - \int v \cdot du\]\)
Substituting the values:
\(\[\int x^6 \cos y dx = x^6 \cdot \cos y \cdot x - \int (\cos y \cdot x) \cdot (6x^5 dx)\]\)
Simplifying:
\(\[\int x^6 \cos y dx = x^7 \cos y - 6 \int x^6 \cos y dx\]\)
Moving the integral term to the left side:
\(\[7 \int x^6 \cos y dx = x^7 \cos y\]\)
Dividing both sides by 7:
\(\[\int x^6 \cos y dx = \frac{x^7 \cos y}{7}\]\)
Now, substituting this result back into our original equation:
\(\[7 \int x^6 \cos y dx = dy\]\)
\(\[\frac{7x^7 \cos y}{7} = dy\)
Simplifying:
x⁷ cos y = dy
Finally, the solution to the given differential equation is:
x⁷ cos y = y + C
where C is the constant of integration.

A coach in a train can seat exactly 72 people for a trip. The train has 12 such coaches. If the train made 156 trips in full capacity in a year, how many people has it carried in that time?
72 x 12 = 864
864 x 156 = 134,784
in the capacity of the year, 134784 people have been carried on the train
merry christmas:)
In the word problem, the train has carried 134,784 people in that year.
How to Solve the Problem?To calculate the total number of people carried by the train in a year, we need to find the number of people carried in a single trip and then multiply it by the total number of trips made in a year.
Each coach can seat exactly 72 people, and there are 12 coaches on the train. So, in a single trip, the train can carry:
72 (people per coach) * 12 (number of coaches) = 864 people
Now, the train made 156 trips in full capacity in a year. So, the total number of people carried in that time would be:
156 (trips) * 864 (people per trip) = 134,784 people
Therefore, the train has carried 134,784 people in that year.

Show that the product of the sample observations is a sufficient statistic for θ > 0 if the random sample is taken from a gamma distribution with parameters α = θ and β = 6.
To show that the product of the sample observations is a sufficient statistic for θ > 0 in the case of a random sample taken from a gamma distribution with parameters α = θ and β = 6, we can use the factorization theorem for sufficient statistics.
Let's denote the random sample as X₁, X₂, ..., Xₙ, where each Xi is an independent and identically distributed random variable following a gamma distribution with parameters α = θ and β = 6.
The probability density function (pdf) of a gamma distribution with parameters α and β is given by:
f(x; α, β) = (1 / (β^α * Γ(α))) * (x^(α - 1)) * exp(-x / β)
where Γ(α) is the gamma function.
The joint pdf of the random sample can be expressed as:
f(x₁, x₂, ..., xₙ; α, β) = (1 / (β^(nα) * Γ(α)^n)) * (x₁ * x₂ * ... * xₙ)^(α - 1) * exp(-(x₁ + x₂ + ... + xₙ) / β)
By the factorization theorem, the product of the sample observations, denoted as T = x₁ * x₂ * ... * xₙ, is a sufficient statistic for θ if we can express the joint pdf as the product of two functions, one depending on the sample observations T and the other on the parameter θ.
Let's rewrite the joint pdf in terms of T:
f(x₁, x₂, ..., xₙ; α, β) = (1 / (β^(nα) * Γ(α)^n)) * T^(α - 1) * exp(-(x₁ + x₂ + ... + xₙ) / β)
Now, we can separate the terms depending on T and θ:
f(x₁, x₂, ..., xₙ; α, β) = (1 / (β^(nα) * Γ(α)^n)) * T^(α - 1) * exp(-(x₁ + x₂ + ... + xₙ) / β) = g(T; α) * h(x₁, x₂, ..., xₙ; β)
Here, we can observe that g(T; α) = (1 / (β^(nα) * Γ(α)^n)) * T^(α - 1) depends only on T and α, and h(x₁, x₂, ..., xₙ; β) = exp(-(x₁ + x₂ + ... + xₙ) / β) depends only on the sample observations and β.
Therefore, we have successfully factorized the joint pdf into two functions, one depending on T and α, and the other depending on the sample observations and β. This confirms that the product of the sample observations T = x₁ * x₂ * ... * xₙ is a sufficient statistic for the parameter θ when the random sample is taken from a gamma distribution with parameters α = θ and β = 6.

On a coordinate plane, a circle has a center at (8, 9). Concentric circles are circles with the same center but different radii. Which equations represent concentric circles along with the circle shown in the graph? Check all that apply. x2 + y2 = 25 (x – 8)² + (y – 9)² = 3 (x – 8)² + (y – 9)² = 14 (x – 8)² + (y + 9)² = 3 (x + 8)² + (y + 9)² = 25 (x + 9)² + (y + 8)² = 3
Answer:
Correct options:
(x – 8)² + (y – 9)² = 3
(x – 8)² + (y – 9)² = 14
Step-by-step explanation:
If the circle has a center at (8,9), the equation for this circle is:
\((x-8)^2 + (y - 9)^2 = r^2\)
All concentric circles have the same center, so their equations need to have the same left side of the equation above.
-> x2 + y2 = 25
This circle has a center at (0,0), so it's not concentric to our circle.
-> (x – 8)² + (y – 9)² = 3
This circle has a center at (8,9), so it's concentric to our circle.
-> (x – 8)² + (y – 9)² = 14
This circle has a center at (8,9), so it's concentric to our circle.
-> (x – 8)² + (y + 9)² = 3
This circle has a center at (8,-9), so it's not concentric to our circle.
-> (x + 8)² + (y + 9)² = 25
This circle has a center at (-8,-9), so it's not concentric to our circle.
-> (x + 9)² + (y + 8)² = 3
This circle has a center at (-8,-9), so it's not concentric to our circle.
Correct options:
(x – 8)² + (y – 9)² = 3
(x – 8)² + (y – 9)² = 14

Adjustment for Multiple Comparisons: Tukey-Kramer
We need to identify the correct answer from the options given.
So, from the table we can conclude that "the results of the ANOVA indicate that both Kia and Honda have significantly better gas mileage than Ford."
This can be inferred from the comparison of LSMEAN numbers in the table.
The LSMEAN number for Ford is 1, for Honda it is 2, and for Kia it is 3. Comparing the values in the table, we can see that the Pr > t values for the comparisons between Ford and both Honda and Kia are less than the significance level (0.05).
This indicates that there are significant differences in gas mileage between Ford and both Honda and Kia, suggesting that both Honda and Kia have significantly better gas mileage than Ford.
