Answer:
Step-by-step explanation:
3p. = 2m - 5q
-2m. = -3p - 5q
Divide through by -2
m. = (3p + 5q) \2
The equation can be rearranged and expressed in terms of p and q is m = (3p+5q)/2.
Given equation 3p = 2m - 5q
3p + 5q = 2m
(3p + 5q) / 2 =m
Hence, m = (3p+5q) / 2
To express the equation in terms of p and q we need to put all the p and q terms to one side of the equation and m terms to another side of the equation. It can be easily seen that 3p is already on one side and we just need to bring a q term to this side which can be done by shifting 5q from the right-hand side to left-hand side. The equation is now 3p+5q. Now to get the equation in terms of m we need to divide the whole equation by 2 which will give m = (3p+5q) / 2.

The time series regression model contains a variable W and a regression equation of y = 200 + W + 2W2 to forecast future values. If W represents a time period, what is the forecast for time period 2 and the forecast error if the actual value for time period 2 is 100? Select the best answer.
forecast value = 210; forecast error is 110
forecast value = 210; forecast error is -110
forecast value = 210; forecast error is 0
forecast value = 100; forecast error is 0
The forecast value for time period 2 is 210, and the forecast error is -110 when the actual value is 100. Option B
To calculate the forecast value for time period 2, we substitute W = 2 into the regression equation:
y = 200 + W + 2W^2
= 200 + 2 + 2(2^2)
= 200 + 2 + 2(4)
= 200 + 2 + 8
= 210
Therefore, the forecast value for time period 2 is 210.
To calculate the forecast error, we compare the forecasted value with the actual value for time period 2. Given that the actual value is 100, the forecast error can be calculated as the difference between the actual value and the forecast value:
Forecast error = Actual value - Forecast value
= 100 - 210
= -110
Hence, the forecast error is -110.
Therefore, the correct answer is:
Forecast value = 210; forecast error is -110. So Option B is correct.

Let $m$ be the smallest integer whose cube root is of the form $n+r$, where $n$ is a positive integer and $r$ is a positive real number less than $1/1000$. Find $n$.
The smallest such $n$ is $12$.
To solve the problem, we can start by expanding $(n+r)^3$ and approximating it by ignoring the term $r^3$, since $r$ is small.
We then want to find the smallest positive integer $n$ such that there exists a positive real number $r$ less than $1/1000$ satisfying the equation. We can try different values of $n$ starting from $n=1$ and incrementing by $1$ until we find a value of $n$ that works.
By testing a few values, we find that $n=12$ works, giving us $1728 + 1296r + 324r^2$, which is less than $(12+1/40)^3$. Therefore, the smallest such $n$ is $12$.

Two surfaces are called orthogonal at a point of intersection P if their normals are perpendicular atthat point.Show that surfaces with equations F(x; y; z) = 0 and G(x; y; z) = 0 are orthogonal at a point Pwhere gradient of F = not equal to 0 and gradient of G is not equal to 0 if and only ifFxGx + FyGy + FzGz = 0 at P :use the above to show that z^2=x^2+y^2 and x^2+y^2+z^2=r^2 are orthogonal on every point of intersection.
by using the condition for orthogonality between surfaces and applying it to the given equation \(z^{2}\) = \(x^{2}\) + \(y^{2}\) and \(x^{2}\) + \(y^{2}\) + \(z^{2}\) = \(r^{2}\) are orthogonal at every point of intersection.
Let's consider the surfaces F(x, y, z) = 0 and G(x, y, z) = 0, where the gradients of F and G are non-zero at the point of intersection P. To prove that the surfaces are orthogonal at P, we need to show that their dot product, FxGx + FyGy + FzGz, is equal to zero at P.
The dot product of the gradients can be written as FxGx + FyGy + FzGz. If this expression evaluates to zero at P, it implies that the gradients are perpendicular, and therefore the surfaces are orthogonal at P.
Now, let's apply this result to the surfaces \(z^{2}\) = \(x^{2}\) + \(y^{2}\) and \(x^{2}\) + \(y^{2}\) + \(z^{2}\) = \(r^{2}\). Taking the gradients of these surfaces, we find that the dot product FxGx + FyGy + FzGz is equal to 2\(z^{2}\) + 2(\(x^{2}\) + \(y^{2}\) + \(z^{2}\)), which simplifies to 3\(z^{2}\) + 2(\(x^{2}\) + \(y^{2}\)).
Since this expression is equal to zero for all points (x, y, z) satisfying the equation of the second surface, \(x^{2}\) + \(y^{2}\) + \(z^{2}\) = \(r^{2}\), we can conclude that the surfaces \(z^{2}\) = \(x^{2}\) + \(y^{2}\) and \(x^{2}\) + \(y^{2}\)+ \(z^{2}\) = \(r^{2}\) are orthogonal at every point of intersection

A median is:In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic feature of the median in describing data compared to the mean is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of a "typical" value. Median income, for example, may be a better way to suggest what a "typical" income is, because income distribution can be very skewed. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median is not an arbitrarily large or small result.

You might also need to use in (1-λ/n)^n = -λ when λ/n = 0
The Poisson distribution becomes a good approximation to the Binomial distribution when the number of trials is large, the probability of success is small, and the expected number of successes is λ = np.
(a) The probability mass functions (PMF) of Bino(np) and Pos(np) with the parameters n = 100, p = 0.2,0.8 for the interval k [0, 100) can be plotted using the MATLAB functions binopdf and poisspdf.
(b) To show that Poisson distribution approximates Binomial distribution when n is large, p is small, and λ = np, we can use the Poisson approximation to Binomial distribution. Using the fact that n-k/k → 1 as n →[infinity], we can simplify the Binomial distribution to:
Bino(n,p) ≈ (np)^k e^(-np)/(k!)
By letting λ = np and replacing in the above expression, we get:
Bino(n,p) ≈ (λ/k)^k e^(-λ)/k!
This expression is the PMF of a Poisson distribution with parameter λ, which proves that Poisson distribution approximates Binomial distribution under the given conditions.

derive an equation that relates the initial release height hx of block x and the speed vs of the two-block system after the collision in terms of mx , my , and fundamental constants, as appropriate.
The law of conservation of energy and momentum can be used to construct the equation that connects the initial release height of block x (hx) and the speed of the two-block system following the collision (v s).
Block x's initial kinetic energy (0.5 * m x * v x2) and potential energy (m x * g * hx) are both equal to the total kinetic energy of both blocks after the collision (0.5 * (m x + m y) * v s).
Combining everything, we get the following equation:
m x * g * hx + 0.5 * m x * v x2 = 0.5 * (m x + m y) * v s2.
where g is the acceleration brought on by gravity, v x is the starting speed of block x, and m x and m y are the masses of blocks x and y.

Both parents must be heterozygous to have a 1/4 chance of having an
affected child. Parent 2 is heterozygous (her father was homozygous recessive, but she has unaffected).
For the child to have the disease, both Parent 1 and Parent 2 would need to be heterozygous
There is a 50% chance of this for Parent 1 and a 100% chance of this for Parent 2 and then, there is a 25% chance that their first child will be affected:
50%× 100% × 25% = 12.5%

The frictional force acting on the cylinder is F= (4.0N)i when a fishing line wrapped around a uniform solid cylinder exerts a constant, horizontal force on it of magnitude 12 app n.
Given that,
A fishing line wrapped around a uniform solid cylinder exerts a constant, horizontal force on it of magnitude 12 app n. The cylinder has a radius of 0.10 m, a mass of 10 kg, and rolls smoothly on the horizontal surface.
We have to find what is the cylinder being frictionally forced by.
We know that,
To ensure that the angular acceleration is positive, we make the unorthodox decision to treat the clockwise sense as positive (as is the linear acceleration of the center of mass, since we take rightward as positive). Applying the linear form of Newton's second law results in
(12 N)−f=Ma
Therefore, f=−4.0 N.
The friction force is discovered to point rightward with a magnitude of 4.0 N, or, in contrast to what we thought when formulating our force equation,

The set of variables that is most likely to have a cause-and-effect relationship is option C: the weight of a box and the postage rate we have to pay to ship the box to California.
Based on the given sets of variables, the set most likely to have a cause-and-effect relationship is:
B. The height of a person and the weight of a person
This is because there is a general correlation between a person's height and their weight, as taller individuals tend to have higher weights. While this is not an absolute rule, there is a stronger cause-and-effect relationship in this set compared to the other options.
This is because the weight of the box is a likely cause of the postage rate, as the heavier the box, the more postage we will have to pay to ship it. In options A and B, there may be a correlation between the variables, but it is less likely that there is a direct cause-and-effect relationship.

Find the area of the head using each persons method. Show your reasoning.
The area of the hexagonal head using each persons (Andre & Lin) method is;
Total Area using Lin's method = 93.6 ft²
Total Area using Andre's method = 93.6 ft²
A) Lin's Method; From division of polygons , we know that a regular hexagon can be divided into 6 equilateral triangles.From the image, a side of the hexagon is 6 inches. This means that all sides of each triangle will be also 6 inches.
Formula for area of a triangle = ¹/₂(base x height)
We see a perpendicular distance spanning from one end of the hexagon to the other end passing through the centre of the hexagon. It passes 2 triangles.
Thus, the height of one triangle = 10.4/2 ft = 5.2 ft
Area of one triangle = ¹/₂ × 6 × 5.2 = 15.6 ft²
Thus, Area of hexagon = area of 6 triangles = 6 × 15.6 = 93.6 ft²
B) Andre's method;Let us first find the area of the rectangle;
Area of rectangle = length × width
Area of rectangle = 10.4 × 6 = 62.4 ft²
For the rectangle, we know three sides now which are;
10.4 ft, 6 ft, 6 ft but we don't know the height and as such we will use heron's formula to get the area of one triangle;
A = √s((s - a)(s - b)(s - c))
where; a,b and c are the 3 sides of the triangle
s = (a + b + c)/2
Thus; s = (10.4 + 6 + 6)/2 = 11.2 ft
Thus;
A = √11.2((11.2 - 10.4)(11.2 - 6)(11.2 - 6))
A = 15.6 ft²
There are 2 triangles and so Area of 2 triangles =2 × 15.6 = 31.2 ft²
Thus;
Total Area = 62.4 ft² + 31.2 ft²
Total Area = 93.6 ft²

Step-by-step explanation:
I see this has no answer and it might be too late.
It's asking us to find dy/dx, after taking log of both sides and apply any useful properties of log.
Take log of both sides:
log(y)=log[x(x+8)(x+9)]
Apply product rule of logarithms on right:
log(y)=log(x)+log(x+8)+log(x+9)
Now differentiate both sides:
y'/y=1/x+1/(x+8)+1/(x+9)
Multiply both sides by y:
y'=y(1/x+1/(x+8)+1/(x+9))
Replace y with x(x+8)(x+9) -> this is from the given equation:
y'=x(x+8)(x+9)(1/x+1/(x+8)+1/(x+9))
Distribute:
y'=(x+8)(x+9)+x(x+9)+x(x+8)

Determine if High school and GPA above 3.0 are independent
Let
\(H \to\) High school
\(G \to\) GPA above 3.0
For both events to be independent, the following must be true
\(P(H\ |\ G) = P(H)\)
From the table:
\(P(H) = \frac{H}{Total}\)
