What is 7/8 expressed as a percent?

Step-by-step explanation:

To convert 6 3/4 meters to centimeters, we need to multiply the value by 100.

First, convert the mixed number to an improper fraction:

6 3/4 = (6 * 4 + 3)/4 = 27/4

Now, multiply the fraction by 100:

(27/4) * 100 = 675/2 = 337.5

Therefore, 6 3/4 meters is equal to 337.5 centimeters.

They suffer loss by selling bananas at 65c.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. With the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Cost of one box = R75

Then, cost of three boxes = R75 x 3

                                            = R225

Now, one box has 12 bunches of 12 bananas each.

Then, one box contain = 12 x 12 = 144 bananas

and, 3 box contain = 144 x 3 = 432 Bananas

If managed to sell 80 % of the bananas then they sold

= 432 x 0.8 = 346 Bananas

So, they earned by selling those bananas

= 346 x 0.65

= R224.9

Thus, they suffer loss.

The chance that the hospital will run out of sleeping pills on any given day is 0.5000 (or 0.5000 with four decimal places).

To calculate the chance that the hospital will run out of sleeping pills on any given day, we can use the normal distribution and Z-score.

First, let's calculate the Z-score using the formula:

Z = (X - μ) / σ

Where:

X = consumption rate per day (1,155 pills)

μ = average consumption rate per day (1,155 pills)

σ = standard deviation (81 pills)

Z = (1,155 - 1,155) / 81

Z = 0

Now, we need to find the probability associated with this Z-score. However, since the demand for sleeping pills can be considered continuous and not discrete, we need to calculate the area under the curve from negative infinity up to the Z-score. This represents the probability of not running out of sleeping pills.

We discover that the region to the left of a Z-score of 0 is 0.5000 using a basic normal distribution table or statistical software.

To find the probability of running out of sleeping pills, we subtract this probability from 1:

Probability of running out of sleeping pills = 1 - 0.5000

Probability of running out of sleeping pills = 0.5000

Therefore, on any given day, the hospital has a 0.5000 (or 0.5000 with four decimal places) chance of running out of sleeping tablets.

No, it is not necessarily true that both ABT and ATB are defined for matrices A and B of size m × n.

In order for the matrix product ABT to be defined, the number of columns in A (which is n) must be equal to the number of columns in BT (which is also n). This means that the number of rows in B (which is m) must be equal to the number of rows in A (which is also m). So, if A and B are both square matrices of size n × n, then ABT is defined

On the other hand, in order for the matrix product ATB to be defined, the number of columns in AT (which is m) must be equal to the number of columns in B (which is also n). This means that the number of rows in A (which is m) must be equal to the number of rows in B (which is also m). So, if A and B are both square matrices of size m × m, then ATB is defined.

However, if A and B are not square matrices, then it is possible that only one of ABT or ATB is defined, or neither of them are defined. In general, the product of two matrices is only defined if the number of columns in the first matrix is equal to the number of rows in the second matrix.

(a) The wave function (r,, d) = Ae(-r/a), with A and a constants. To determine the expected value of energy E, we must first compute |H|>, where H is the Hamiltonian operator.

H = -(2/2m) 2 + V(r) is the Hamiltonian operator for a particle in a spherically symmetric potential, where is the reduced Planck constant, m is the particle's mass, 2 is the Laplacian operator, and V(r) is the potential energy. We may assume that V(r) = 0 as r approaches infinity since the potential energy V(r) is given to be zero at infinity. As a result, the Laplacian operator in spherical coordinates is reduced to 1/r2(d/dr)(r2(d/dr)), and we obtain:\(< ψ|H|ψ > = ∫∫∫ ψ*(r,θ,φ) [-2/2m (1/r2)(d/dr)(r2(d/dr)) + V(r) (r,,)] dτ where d = r2 sin dr d d d\) is the volume element.

False, The eigenvalues of a matrix A are not same as the eigenvalues of the reduced row echelon form of A.

A matrix's eigenvalues are not the same as those of the matrix's reduced row echelon form, contrary to what is claimed.

This is due to the fact that when a matrix is reduced to its echelon form via row operations, its eigenvalues may not always stay the same. The eigenvalues of a matrix may be different in the reduced row echelon form than they are in the original matrix as a result.

Think about these matrices as an illustration:

Likewise, B's reduced row echelon form is B, and B's eigenvalues are both 1.

A = [1 2; 2 1]

and

B = [1 0; 0 1].

The eigenvalues of a matrix and its reduced row echelon form are thus typically not the same.

FALSE. The eigenvalues of a matrix A are NOT the same as the eigenvalues of the reduced row echelon form of A.

Explanation:

Eigenvalues are scalar values that, when multiplied by an eigenvector, produce the same effect as the original matrix A on that eigenvector. Mathematically, for a matrix A and its eigenvector v, Av = λv, where λ is the eigenvalue.

Row echelon form is a matrix transformation using elementary row operations to obtain a triangular form. The reduced row echelon form (RREF) is a further simplified version of the row echelon form.

However, transforming a matrix A to its RREF changes the properties of the matrix, and therefore the eigenvalues of matrix A and its RREF are generally not the same. The eigenvalues are preserved only under specific matrix transformations, such as similarity transformations, which row echelon form is not one of them.

lets take

x+y=100 firstly.

then x=100-y equation (i)

Now,

x-y=10

Putting value of x from equation(i)

100-y-y=10

-2y=10-100

-2y=-90

therefore, y=45

Now,

putting value of y in equation(i)

we get

x=100-45

ie x=55

hence, x=55 & y=45

Answer:

The solution is (55, 45).

Step-by-step explanation:

Solve the system of linear equations

x + y = 100

x - y = 10

through elimination by addition / subtraction.

Combining these two equations temporarily eliminates y, leaving us with 2x = 110.  Then x = 55.

Substituting 55 for x in the first equation, we get:

55 + y = 100.  Subtracting 55 from both sides leaves us with y = 45.

The solution is (55, 45).

Step-by-step explanation:

First, you would set up a proportion using the person's measurements and the measurements you do have from the building. You would put your actual value on top of one of the proportions, 6, then put its shadow value, 3.2, on the bottom. Then, you would add 18.5 to the bottom of your other fraction.

Next, you would cross multiply and divide. If you don't know what that means, you will multiply 18.5 by 6, and get 111. Then, divide this number by 3.2. This should make you get 34.6875, so then you round to the nearest hundredths place to get 34.69.

To estimate the mean per capita income for a major city in California with an error of at most $0.56 at the 85% confidence level, the economist needs to determine the required sample size.

To calculate the required sample size, we can use the formula: \(n = \left(\frac{{Z \cdot \sigma}}{{E}}\right)^2\), where \(n\) is the sample size, \(Z\) is the Z-score corresponding to the desired confidence level (in this case, for 85% confidence level, \(Z \approx 1.44\)), \(\sigma\) is the known standard deviation (\$6.6), and \(E\) is the desired margin of error (\$0.56). Plugging in the values, we have \(n = \left(\frac{{1.44 \cdot 6.6}}{{0.56}}\right)^2 \approx 52\). Therefore, a sample size of approximately 52 would be required to estimate the mean per capita income with an error of at most $0.56 at the 85% confidence level.

Step-by-step explanation:

In the balance sheet, mortgage notes payable are reported as a long-term liability only.

Mortgage notes payable represent the amount owed by a company for a mortgage loan. These loans are typically long-term obligations that are expected to be repaid over an extended period, often several years. Therefore, mortgage notes payable are classified as long-term liabilities in the balance sheet.

Current liabilities are obligations that are expected to be settled within a short period, usually one year or less. Since mortgage notes payable typically have a longer repayment term, they do not meet the criteria to be classified as current liabilities.

By reporting mortgage notes payable as a long-term liability, the balance sheet provides a clear distinction between the company's short-term and long-term obligations, helping stakeholders understand the company's financial position and obligations over different time horizons.

The root of the equation sinx = 2x-3 is 0.8401 (approx).

Given equation is sinx = 2x-3

We need to solve this equation using false position method.

False position method is also known as the regula falsi method.

It is an iterative method used to solve nonlinear equations.

The method is based on the intermediate value theorem.

False position method is a modified version of the bisection method.

The following steps are followed to solve the given equation using the false position method:

1. We will take the end points of the interval a and b in such a way that f(a) and f(b) have opposite signs.

Here, f(x) = sinx - 2x + 3.

2. Calculate the value of c using the following formula: c = [(a*f(b)) - (b*f(a))] / (f(b) - f(a))

3. Evaluate the function at point c and find the sign of f(c).

4. If f(c) is positive, then the root lies between a and c. So, we replace b with c. If f(c) is negative, then the root lies between c and b. So, we replace a with c.

5. Repeat the steps 2 to 4 until we obtain the required accuracy.

Let's solve the given equation using the false position method.

We will take a = 0 and b = 1 because f(0) = 3 and f(1) = -0.1585 have opposite signs.

So, the root lies between 0 and 1.

The calculation is shown in the attached image below.

Answer:

The regular price of the microwave is $122.

Step-by-step explanation:

To find the regular price of the microwave, we'll use the discount percentage and the amount saved.

The store has marked down the microwave by 45%. This means the sale price is 55% of the regular price.

If Donald can save $55 on the sale, we know that $55 is equal to 45% of the regular price.

By setting up the equation:

45% of the regular price = $55

We can calculate the regular price:

Regular price = $55 / 0.45

Calculating this, we find:

Regular price ≈ $122.22

Therefore, the regular price of the microwave is approximately $122.

Donald Houston can save $55 on a new microwave if he buys it on sale. The store has marked down the microwave 45%, then its regular price is $122.22.

To determine the regular price of the microwave, we can set up an equation using the information given to us on the question.

Let's denote the regular price of the microwave as x,

Given: Discount percentage= 45%,

Amount saved= $55,

Therefore, this gives us the equation:

(Regular price) - (Discount price) = (Regular price) - (Amount saved)

x - (45%)x = x - $55 .............(i)

which further gives us the equation,

0.45x = $55............(ii)

⇒ x = $55/0.45,

Therefore,

x = $122.22 approx.

Thus, Donald Houston can save $55 on a new microwave if he buys it on sale. The store has marked down the microwave 45%, then its regular price is $122.22.
