the impedance Z, in ohms, of a circuit element is defined as the ratio of the phasor voltage V, in volts, across the element to the phasor current I, in amperes, through the elements. That is, Z = V/I. If the voltage across the circuit element is 35+13i volts and the current through the element is 5-3i amperes, determine the impedance.

Answer:

Common side: UV

Step-by-step explanation:

The test-statistic (z-score) is 1.19984.

To find the test statistic (z-score) using the p-value, you will need to use the inverse of the standard normal cumulative distribution function (CDF), also known as the inverse normal function or the "normal inverse function." This function can be found using a calculator or a spreadsheet program with built-in functions, or you can use a table of standard normal probabilities to find the corresponding z-score for a given p-value.

For example, if the p-value is 0.05, you would look up the corresponding z-score in a table of standard normal probabilities and find that it is approximately 1.645. This means that the test statistic (z-score) for a p-value of 0.05 is 1.645.

It's important to note that this method only works for a one-tailed test, for a two-tailed test you need to divide your p-value by 2 and then use the inverse normal function.

so, the p-value is 0.1151, you would look up the corresponding z-score in a table of standard normal probabilities and find that it is approximately 1.19984.

Therefore, the test-statistic (z-score) is 1.19984.

Answer:

a negative integer

Step-by-step explanation:

We can first establish basic rules that we can apply:

the product of one negative integer:

-1 = -1

(odd number = negative)

the product of two negative integers:

-1 · -1 = 1

(even number = positive)

the product of three negative integers:

-1 · -1 · -1 = 1   {-1 · -1 = 1, 1 · -1 = -1}

(odd number = negative)

the product of four negative integers:

-1 · -1 · -1 · -1 = 1

(even number = positive)

So, we can understand that an even number of integers changes the original value to its negative/positive [the opposite +/- sign from the original number], whilst an odd number of integers does not change the +/- sign.

So, because 23 is an odd number, the product will stay negative.

The standard error of the average sample weight when 15 participants are randomly selected for the sample is 9.05 (rounded to two decimal places).

The standard error of the average sample weight when 15 participants are randomly selected for the sample can be calculated using the formula given below:SE = σ/√nWhere,σ = standard deviation of the populationn = sample sizeSE = standard error of the meansubstituting the given values,SE = 35/√15 = 9.05

Note:When using the given formula, it is important to note that it assumes a normal distribution of sample means. The standard error is used to estimate the true value of the mean from the sample data. The larger the sample size, the smaller the standard error. The smaller the standard error, the more precise the estimate of the true value of the mean.

Therefore, Guy would be willing to pay approximately $5,989.00 today for this investment based on the expected cash flows and the interest rate. The correct option is C) $5,989.00.

The formula for present value of a series of cash flows is given by:

\(PV = C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^3 + ... + Cn/(1+r)^n\)

Where:

PV is the present value,

C1, C2, C3, ..., Cn are the cash flows at different time periods,

r is the interest rate, and

n is the number of time periods.

In this case, the cash flows are $2,000, $1,500, $3,000, and $400, occurring at the end of year 1, year 2, year 3, and year 4, respectively. The interest rate (r) is 6%.

Substituting these values into the formula, we have:

\(PV = 2,000/(1+0.06)^1 + 1,500/(1+0.06)^2 + 3,000/(1+0.06)^3 + 400/(1+0.06)^4\)

Simplifying the expression:

\(PV ≈ 2,000/1.06 + 1,500/1.06^2 + 3,000/1.06^3 + 400/1.06^4\)

Using a calculator, we find that PV ≈ $5,989.00.

For Part A the probability is 0.0095 and for Part B the probability is

0.0043.

Probability of defect is perhaps the most important indicator of a manufacturing process's quality. It's a statistical technique used to indicate how often a product will fail during its lifespan, which in turn allows you to estimate the likelihood that an item will result in customer dissatisfaction.

Part A:

The number of rivets=22 rivets

Probability that no rivet is defective= \((1-p)^{22}\)

The probability that at least one rivet is defective=1-\((1-p)^{22}\)

For 19% of all seams need reworking, probability that a rivet is defective is given by

1-\((1-p)^{22}\) = 0.19

\((1-p)^{22} = 1-0.19\\(1-p)^{22} = 0.81\\ p=1-\sqrt[22]{0.81} \\p=0.0095\)

Part B:

For 9% of all seams need reworking, probability of a defective rivet is:

1-\((1-p)^{22}\) = 0.09

\((1-p)^{22} = 1-0.09\\(1-p)^{22} = 0.91\\ p=1-\sqrt[22]{0.91} \\p=0.0043\)

Hence, For Part A the probability is 0.0095 and for Part B the probability is 0.0043.

Answer: It would represent a linear function.

Step-by-step explanation:

Every time, the amount of blocks increase by 3, which would be the slope of it were on a graph, and it is constant. It’s not a quadratic nor an exponential function because it is not divided or multiplied at a certain factor, but it just adds by 3 each time.

It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. Therefore, option B is true.

We are given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F

We know that the formula

\(\dfrac{C}{5} = \dfrac{F - 32}{9}\)

If we are substituting c = -40

Then, we get

\(\dfrac{C}{5} = \dfrac{F - 32}{9}\\\\\dfrac{-40}{5} = \dfrac{F - 32}{9}\\\\-8 \times 9 = F - 32\\\\F = -72 + 32\\\\F = -40\)

For every Celsius temperature, we get only one value of Fahrenheit.

The function is one-one because for every value of Celsius we get a unique value of Fahrenheit.

Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

Therefore, option B is true.

The general solution is the sum of the particular solution and the complementary function: y((x) = (3/4)x + 1/2 + (C1 + C2x)e⁻²ˣ, where C1 and C2 are arbitrary constants.

To solve the given differential equation using the method of undetermined coefficients, assume a particular solution of the form:

y_p(x) = Ax + B

where A and B are constants to be determined.

First, let's find the derivatives of y_p(x):

y'_p(x) = A

y''_p(x) = 0

Now, substitute these derivatives into the original differential equation:

0 + 4(A) + 4(Ax + B) = 3x + 5

Simplifying this equation:

4Ax + 4B + 4A = 3x + 5

Now, equate the coefficients of like terms on both sides of the equation:

4A = 3         (coefficient of x on the right-hand side)

4B + 4A = 5    (constant term on the right-hand side)

Solving these equations simultaneously:

4A = 3

4B + 4A = 5

From the first equation, we find A = 3/4. Substituting this value into the second equation:

4B + 4(3/4) = 5

4B + 3 = 5

4B = 2

B = 1/2

Therefore, the particular solution is:

y_p(x) = (3/4)x + 1/2

To find the general solution, we also need the complementary function. The characteristic equation for the homogeneous equation y'' + 4y' + 4y = 0 is:

r² + 4r + 4 = 0

Factoring this equation, we have:

(r + 2)² = 0

The characteristic equation has a repeated root of -2. Therefore, the complementary function is:

y_c(x) = (C1 + C2x)e⁻²ˣ

where C1 and C2 are constants to be determined.

Hence, the general solution is the sum of the particular solution and the complementary function: y(x) = (3/4)x + 1/2 + (C1 + C2x)e⁻²ˣ , where C1 and C2 are arbitrary constants.

the sample size required to estimate the proportion of adults with high-speed Internet access depends on whether a prior estimate is 753

(a) When using a previous estimate of 0.58, we can calculate the sample size. The formula for sample size estimation is n =\((Z^2 p q) / E^2,\) where Z is the Z-score corresponding to the desired confidence level, p is the estimated proportion, q is 1 - p, and E is the desired margin of error.

Using a Z-score of 1.645 for a 90% confidence level, p = 0.58, and E = 0.03, we can calculate the sample size:

n = \((1.645^2 0.58 (1 - 0.58)) / 0.03^2\)) ≈ 806.36

Therefore, a sample size of approximately 807 should be obtained.

(b) Without any prior estimate, a conservative estimate of 0.5 is commonly used to calculate the sample size. Using the same formula as above with p = 0.5, the sample size is:

n = \((1.645^2 0.5 (1 - 0.5)) / 0.03^2\) ≈ 752.89

In this case, a sample size of approximately 753 should be obtained.
