If n divided by m equals 7/8,
what does m divided by n equal?
Step-by-step explanation:
1,
It is found that m divided by n is equal to 8/7.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, a/ b = a divided in b equal parts.
If n divided by m equals 7/8, then m divided by n equal.
n / m = 7/8
Then m/n = 8/7
Therefore, m divided by n is equal to 8/7.

sat scores in one state is normally distributed with a mean of 1403 and a standard deviation of 200. Suppose we randomly pick 32 SAT scores from that state. a) Find the probability that one of the scores in the sample is greater than 1484. P(X > 1484) = b) Find the probability that the average of the scores for the sample of 48 scores is greater than 1484 P(X > 1484) = Round each answer to at least 4 decimal places.
The probability that one of the scores in the sample is less than 1484 is 0.2437 .
a)Given that mean u = 1403
standard deviation σ = 200
sample size n = 32
P(x>1484) = P(X-u/σ > 1484-1403/200)
= P (z > 0.405)
P(x>1484) = 0.2437 .
hence the probability that one score is greater than 1484 is 0.405 .
b) Now we have to find the average of the scores of 48 samples.
P(x>1484)
= P(x-μ/ σ/√n> 1484-1403 /200/√48)
= P(z>2.805.)
Now we will use the normal distribution table to calculate the p value to be 0.002516.
p-value = 0.0025
Normal distributions are very crucial to statistics because not only they are commonly used in the natural and social sciences but also to describe real-valued random variables with uncertain distributions.
They are important in part because of the central limit theorem. This claim states that, in some cases, the average of many samples (observations) of a random process with infinite mean and variance is itself a random variable, whose distribution tends to become normal as the number of samples increases.

Exercise 8.4.5. Differential equations can also be given in different coordinate systems. Suppose we have the system r' = 1 - r^2, 0 = 1 given in polar coordinates. Find all the closed trajectories and check if they are limit cycles and if so, if they are asymptotically stable or not.
The given differential equation r' = 1 - r^2, 0 = 1 in polar coordinates has a closed trajectory and a limit cycle at r = 1, which is asymptotically stable.
To find all the closed trajectories and check if they are limit cycles in the given differential equation r' = 1 - r^2, 0 = 1 in polar coordinates, follow these steps:
Step 1: Analyze the given differential equation.
The system is given in polar coordinates as r' = 1 - r^2 and θ' = 1. Since θ' = 1, the angle θ increases linearly with time, and we can focus on the radial part r' = 1 - r^2.
Step 2: Identify equilibrium points.
To find the equilibrium points, we need to find the values of r for which r' = 0. Setting r' = 1 - r^2 equal to 0, we have:
1 - r^2 = 0
r^2 = 1
r = ±1
Step 3: Analyze the stability of the equilibrium points.
For r < 1, we have r' > 0, meaning that r will increase with time.
For r > 1, we have r' < 0, which means that r will decrease with time.
For r = 1, r' = 0, indicating that r is constant.
Step 4: Determine the closed trajectories and limit cycles.
From the stability analysis, we can see that the only closed trajectory is r = 1, as r is constant at this value. Since the radial part is dependent only on r and not on θ, this closed trajectory is a limit cycle.
Step 5: Determine if the limit cycle is asymptotically stable or not.
Since r' > 0 for r < 1 and r' < 0 for r > 1, any trajectory inside the limit cycle r = 1 will move outward towards it, while any trajectory outside the limit cycle will move inward towards it.
Therefore, the limit cycle is asymptotically stable.

How do I look in a different basis. Find the matrix form of S z
when the base vectors are the eigen kets of S y
. (You know the spin operators and their eigenstates in the S z
basis.)
The matrix form of S z when the base vectors are the eigenkets of S y is:
⎡ 0.5 0.5 ⎤
⎢ ⎥
⎣-0.5 0.5 ⎦.
What is the significance of the eigenkets of S y in determining the matrix form of S z?The matrix form of S z, when the base vectors are the eigenkets of S y, can be obtained by considering the spin operators and their eigenstates in the S z basis. Let's denote the eigenkets of S y as |+⟩ and |−⟩, corresponding to the eigenvalues +1/2 and -1/2, respectively. In the S z basis, these eigenkets can be represented as linear combinations of the base vectors |↑⟩ and |↓⟩, which are the eigenkets of S z.
The first step is to express |+⟩ and |−⟩ in terms of |↑⟩ and |↓⟩. We have:
|+⟩ = (1/√2)(|↑⟩ + |↓⟩)
|−⟩ = (1/√2)(|↑⟩ - |↓⟩)
Next, we need to find the matrix elements of S z with respect to these eigenkets. The matrix elements are given by the inner products between the eigenkets and the S z operator. We know that S z|↑⟩ = +1/2|↑⟩ and S z|↓⟩ = -1/2|↓⟩. Using these relations, we can compute the matrix elements:
⟨+|S z|+⟩ = (1/√2)(⟨↑| + ⟨↓|)(+1/2)(|↑⟩ + |↓⟩)
= (1/√2)(1/2)(⟨↑|↑⟩ + ⟨↑|↓⟩ + ⟨↓|↑⟩ + ⟨↓|↓⟩)
= (1/√2)(1/2)(1 + 0 + 0 + 1)
= 1
Similarly, we find ⟨+|S z|−⟩ = 0, ⟨−|S z|+⟩ = 0, and ⟨−|S z|−⟩ = -1. These values can be arranged in matrix form:
⎡ 1 0 ⎤
⎢ ⎥
⎣ 0 -1 ⎦
Therefore, the matrix form of S z, when the base vectors are the eigenkets of S y, is given by:
⎡ 1 0 ⎤

A line has a slope of -1/9 and includes the points (-2,y) and (7,-2).
What is the value of y?
(Pls help as soon as you can)
For a line having a slope of -1/9, the value for y is obtained as -1.
What is slope?
A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
We can use the point-slope form of the equation of a line to solve this problem.
The point-slope form is -
y - y1 = m(x - x1)
where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) is any other point on the line.
We are given that the line has a slope of -1/9.
Let's use the point (-2, y) as our (x1, y1) point.
Plugging in the values in the equation -
y - y1 = m(x - x1)
y - y1 = (-1/9)(x - (-2))
y - y1 = (-1/9)(x + 2)
Now we can use the other given point, (7, -2), and plug in the values for x and y -
-2 - y1 = (-1/9)(7 + 2)
-2 - y1 = (-1/9)(9)
-2 - y1 = -1
Solving for y1, we get -
y1 = -2 + 1
y1 = -1
Therefore, the value of y is -1.

What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The line x = -2 is a vertical line passing through the point (-2, y) for all y. Since we want a line parallel to this line, it must also be a vertical line.
Therefore, the equation of the line that is parallel to x = -2 and passes through the point (-5, 4) is simply x = -5.
