The adjusted trial balance for revenue in the accounting worksheet is 20,000.

Trial balance in the accounting worksheet is a financial report where the credit entries and debit entries are listed which is used to audit the accounting system of business or organization internally. It is used to confirm that the sum of all credits and debits must be equal.

Here we have the credit of 15,000 for revenues.

Then the trial balance is adjusted with a credit of 5000.

If we have two debits or credits, we will add them.

So the adjusted trial balance = 15,000 + 5,000 = 20,000

All trinomials of the form x2 +bx+c can be factored. it is a false statement.

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the monomial, binomial, and trinomial, etc. ax+b is a polynomial.

Here,

Not all trinomials of the form x² +bx+c can be factored in, but many can. Whether or not a trinomial can be factored depends on the values of b and c, and sometimes on the value of an as well. For example, the trinomial x² + 2x + 1 can be factored as (x+1)², while the trinomial x² + 2x + 3 cannot be factored using real numbers.

Answer:To find out how many pizzas Mrs. Smith should order, you need to divide the total number of slices of pizza needed by the number of slices in one pizza.

Since there are 1224 students in the grade 4 and 5 class and Mrs. Smith wants to give each student three slices of pizza, she will need 1224 students * 3 slices/student = <<1224*3=3672>>3672 slices of pizza.

If a medium pizza comes with eight slices, Mrs. Smith will need to order 3672 slices / 8 slices/pizza = <<3672/8=459>>459 medium pizzas.

Therefore, Mrs. Smith should order 459 medium pizzas for her pizza party.

(a) The real discrete Fourier transform (DFT) is calculated for the given data set to analyze the helicopter's acoustic signature.

(b) To obtain the ck values and illustrate the relative size of each term in the Fourier series, we calculate the magnitude of each coefficient and plot their amplitudes on a bar graph against the corresponding frequency component, k.

To analyze the helicopter's acoustic signature, the real DFT is computed for the provided data set. The DFT transforms the time-domain measurements of acoustic pressure into the frequency domain, revealing the different frequencies present and their corresponding amplitudes. This analysis helps in understanding the spectral characteristics of the helicopter's acoustic signature and identifying prominent frequency components.

Using the Fourier series representation, the amplitudes (ck's) of the different frequency components in the Fourier series are determined. These amplitudes represent the relative sizes of each term in the series, indicating the contribution of each frequency component to the overall acoustic signature. By plotting the amplitudes on a bar graph, the relative strengths of different frequency components become visually apparent, enabling a clear comparison of their importance in characterizing the helicopter's acoustic signature.

The total number of possible 7-place license plates are 67600000.

Given: A 7-plate license plate. 2 places are for letters and 5 places are for numbers. To find how many different 7-plate license plates are possible

Let's solve the given problem:

The license plate has 7 places. 2 places are for letters and the remaining 5 places are for numbers.

Therefore, the total number of ways in which the 7-place license plate can fill are: Total possible ways in which the two letters can be filled × Total possible ways in which the 5 number places can be filled

= 676 × 100000

= 67600000 ways

Hence the total number of possible 7-place license plates are 67600000.

Answer:

common difference is 0.5

first term is 5

Step-by-step explanation:

use the formula for the nth term of an ap Tn=a+(n-1)d

T12=10.5

T18=13.5

therefore come up with two equations

T12=a+(12-1)d

10.5=a+11d(1st equation)

T18=a+(18-1)d

13.5=a+17d(2nd equation)

then solve both as a simultaneous equation

a+11d=10.5

a+17d=13.5

-6d/-6=-3/-6

d=0.5

use one of the equations to find the first term

a+11(0.5)=10.5

a+5.5=10.5

a=10.5-5.5

a=5

The upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

To determine the upper bound of the 95% confidence interval for the average age in the U.S., we can use the sample data from the survey. The sample size is 1072 people, randomly selected from the U.S. population, with a minimum age of 12. By calculating the average age of the respondents, we can estimate the average age of the entire U.S. population.

Using the given information that the average age of the respondents is 43.56 years, and assuming that the sample is representative of the population, we can calculate the standard error. The standard error measures the variability of the sample mean and indicates how much the sample mean might deviate from the population mean.

Using statistical methods, we can calculate the standard error and construct a confidence interval around the sample mean. The upper bound of the 95% confidence interval represents the highest plausible value for the population average age based on the sample data.

Therefore, based on the provided information and calculations, the upper bound of the 95% confidence interval for the average age in the U.S. is 48.29 years.

The total amount of kinetic and potential energy in a system is called mechanical energy.

Mechanical energy is the sum of kinetic energy and potential energy within a system. Kinetic energy (KE) is the energy possessed by an object due to its motion, and it is calculated using the formula KE = (1/2)mv², where m is the mass of the object and v is its velocity. Potential energy (PE) is the energy possessed by an object due to its position or condition, and it can be gravitational potential energy, elastic potential energy, or other forms. The total mechanical energy (ME) is obtained by adding the kinetic and potential energy together, so ME = KE + PE.

In summary, the total amount of kinetic and potential energy in a system is referred to as mechanical energy. This energy accounts for both the motion and position-related energies within the system. The calculation of mechanical energy involves summing the kinetic energy, which depends on the mass and velocity of the objects, with the potential energy, which can arise from factors such as gravity or elasticity. Understanding and analyzing the mechanical energy in a system can provide insights into its overall energy distribution and behavior.

Answer:

put the formula

(a-b) all square

Answer:

Step-by-step explanation:

The area for a trapezoid is

\(A=\frac{1}{2}h(b_{1}+b_{2})\)

h is the length of ST, one of the bases is the length of MK, and the other base is the length of AS.  First we'll find h:

The coordinates for S are (0, -2) and T are (1, 2). Using the distance formula:

\(d=\sqrt{(1-0)^2+(2-(-2))^2\) and

\(d=\sqrt{17}\).  So h = √17

Now for the length of MK. The coordinates for M are (-7, 4) and for K (5, 1). Using the distance formula again:

\(d=\sqrt{(-7-5)^2+(4-1)^2}\) and

\(d=\sqrt{(-12)^2+(3)^2}\) so

\(d=\sqrt{153}\) which simplifies to

\(d=3\sqrt{17}\). So MK = 3√17.

Now for the length of AS. The coordinates for A: (-4, -1) and for S: (0, -2). Using the distance formula one more time:

\(d=\sqrt{(-4-0)^2+(-1-(-2))^2}\) and

\(d=\sqrt{(-4)^2+(1)^2}\) and

\(d=\sqrt{17}\). So AS = √17.

Now we can fill in our area formula:

\(A=\frac{1}{2}(\sqrt{17})(3\sqrt{17}+\sqrt{17})\)

Simplifying a bit:

\(A=\frac{1}{2}(\sqrt{17})(4\sqrt{17})\) and simplifying a bit more:

\(A=\frac{4*17}{2}\) and

A = 34
