Answer:

Step-by-step explanation:

when x intercept is points given, then y = 0

So far, you have y = 5x + b where b = the yintercept

x = 2

y = 0

0 = 5x + b

0 =5 * 2 + b

0 = 10 + b             Subtract 10 from both sides.

-10 = b

Equation: y = 5x - 10

The sampling distribution for the sample mean will be normally distributed with a mean of $47 and a standard deviation of approximately $0.73.

The sampling distribution for the sample mean in this scenario would also be normally distributed, with a mean of $47 (the same as the population means) and a standard deviation of $5/sqrt(47) (the standard error of the mean).

This means that if we were to take multiple random samples of size 47 from this population, the means of each sample would be normally distributed around $47, and the spread of the means would be smaller than the spread of the individual amounts purchased due to the central limit theorem.

Given that the amount of gasoline purchased per car at a large service station is normally distributed with a mean of $47 and a standard deviation of $5, and you have a random sample of 47 cars, we can describe the sampling distribution for the sample mean using the following information:

1. The shape of the sampling distribution: Since the original population is normally distributed, the sampling distribution of the sample mean will also be normally distributed according to the Central Limit Theorem.

2. The mean of the sampling distribution (μ_X): The mean of the sampling distribution will be equal to the mean of the population, which is $47.

3. The standard deviation of the sampling distribution (σ_X): To find the standard deviation of the sampling distribution, we need to divide the population standard deviation (σ) by the square root of the sample size (n). In this case, σ = $5 and n = 47.

σ_X = σ / √n = 5 / √47 ≈ 0.73

So, the sampling distribution for the sample mean will be normally distributed with a mean of $47 and a standard deviation of approximately $0.73.

Given that the cost is $1.10 per pound, we can calculate the cost per servable pound by dividing the total cost ($1.10 * 4 pounds) by the servable weight (2 pounds). Therefore, the correct option is c. $2.20.

The original weight of the food item is 4 pounds, and the cost per pound is $1.10. Therefore, the total cost of the food item is 4 pounds * $1.10 = $4.40.

The servable weight of the food item is 2 pounds. To find the cost per servable pound, we divide the total cost ($4.40) by the servable weight (2 pounds):

Cost per servable pound = Total cost / Servable weight = $4.40 / 2 pounds = $2.20.

Hence, the cost per servable pound for this food item is $2.20. Therefore, the correct option is c. $2.20.

Answer:

Radius r = 1.

Step-by-step explanation:

Area of MNOP = (√2π)^2 = 2π.

Area 1 = Area 2, so

2π = 2πr^2

Dividing both sides by 2π:-

r^2 = 1.

r = 1.

In terms of input and output, we can define V_in as the input voltage and V_out as the output voltage across the capacitor. This corresponds to a voltage divider circuit with the capacitor as the lower leg and the resistor as the upper leg. The circuit acts as a low-pass filter that attenuates high-frequency signals and passes low-frequency signals.

To reverse engineer a RCL circuit that has the given system function, we can start by expanding the equation to get:
H(s) = (s + ß)(As^2 + Bs + C)/(s + a)
We can then factorize the denominator to get:
H(s) = (s + ß)(As^2 + Bs + C)/(s + a)(1)
We can recognize the denominator (s + a) as the transfer function of a simple first-order low-pass filter with a time constant of 1/a. To create the numerator (As^2 + Bs + C), we can use a second-order circuit with a similar transfer function. Specifically, we can use a series RLC circuit with a capacitor and inductor in parallel with a resistor.
The circuit diagram would look like this:
V_in ----(R)----(L)-----+-----[C]----- V_out
                          |
                          |
                        -----
                         ---
                          -
where R, L, and C are the values we need to solve for symbolically.
To derive the differential equations, we can use Kirchhoff's voltage and current laws. Assuming that the voltage across the capacitor is V_C and the current through the inductor is I_L, we can write:
V_in - V_C - IR = 0  (Kirchhoff's voltage law for the loop)
V_C = L dI_L/dt     (definition of inductor voltage)
I_L = C dV_C/dt     (definition of capacitor current)
Substituting the second and third equations into the first equation and simplifying, we get:
L d^2V_C/dt^2 + R dV_C/dt + 1/C V_C = V_i
This is the differential equation for the circuit.To find the system function, we can take the Laplace transform of the differential equation and solve for V_out/V_in:
V_out/V_in = H(s) = 1/(s^2 LC + sRC + 1
Comparing this expression with the system function given in the question, we can identify:
ß = 0
A = C
B = R
a = 1
ß and a correspond to the poles of the transfer function, while A, B, and C correspond to the coefficients of the numerator polynomial.
In terms of input and output, we can define V_in as the input voltage and V_out as the output voltage across the capacitor. This corresponds to a voltage divider circuit with the capacitor as the lower leg and the resistor as the upper leg. The circuit acts as a low-pass filter that attenuates high-frequency signals and passes low-frequency signals.

The difference written in scientific notation is:

1.1×10⁴ - 5.6×10² = 1.044×10⁴

Here we have two numbers in scientific notation, and we want to find the difference between them, it is:

1.1×10⁴ - 5.6×10²

To find that difference, we need to find a common factor between the two numbers, we can write the first one as:

1.1×10⁴ = 110×10²

Then we can take the difference:

1.1×10⁴ - 5.6×10²

110×10² - 5.6×10² = (110 - 5.6)×10² = 104.4×10²

Answer: False

Step-by-step explanation:

The x-value of 1 maps onto 4 different y values.

There are two solutions: x = -3 and x = -7.

Let's analyze each equation to determine the number of solutions and provide explanations:

x² - 144 = 0

This equation can be rewritten as (x - 12)(x + 12) = 0. It is a quadratic equation in the form of (x - a)(x + a) = 0, where a is a constant. In this case, a = 12.

Since we have two factors that multiply to give zero, either (x - 12) = 0 or (x + 12) = 0 must be true for the equation to hold.

Thus, there are two solutions: x = 12 and x = -12.

x² + 1440

This equation does not contain an equal sign, so it is not an equation. It is an expression. Therefore, it does not have any solutions.

x (x - 5) = 0

This equation is a product of two factors equal to zero. Either x = 0 or (x - 5) = 0 must be true for the equation to hold. Thus, there are two solutions: x = 0 and x = 5.

(x - 8)² = 0

This equation is a perfect square trinomial. The square of any number is always non-negative, and it only equals zero when the number itself is zero. Thus, the equation (x - 8)² = 0 has only one solution: x = 8.

(x + 3)(x + 7) = 0

This equation is a product of two factors equal to zero. Either (x + 3) = 0 or (x + 7) = 0 must be true for the equation to hold. Thus, there are two solutions: x = -3 and x = -7.

To summarize:

x² - 144 = 0 has two solutions: x = 12 and x = -12.

x² + 1440 does not have any solutions.

x (x - 5) = 0 has two solutions: x = 0 and x = 5.

(x - 8)² = 0 has one solution: x = 8.

(x + 3)(x + 7) = 0 has two solutions: x = -3 and x = -7.

Option B is the correct answer, The set of correlations which correctly shows the highest to lowest degree of relation is -0.91, +0.83, +0.10, -0.03.

What is correlation?

In statistics, the correlation is a technique used to determine the relationship between the two variables. The correlation's range is from -1 to +1. There are three primary categories of correlation: no correlation, positive correlation, and negative correlation. When the correlation value is zero, there is no association; the correlation value that is closest to zero indicates the weakest degree of relationship.

We must select the set of correlations in the question that accurately displays the highest to the lowest degree of relation.

Option B is the best choice since we must take the absolute value into account in order to determine the relationship's degrees. Here, the absolute values drop from 0.91 to 0.03.

Option A is incorrect since the absolute values decline from 0.91 to 0.03 and then climb to 0.10 in this situation.

Because the absolute values are not listed in decreasing order, Option C is incorrect.

Because the absolute values in this situation are not ordered in decreasing order, Option D is also a incorrect choice.

Therefore, option B, is the correct option.

The value of Double integral will be \(\mathrm{I}=4 \int_0^4 \ln |1+\mathrm{x}| \mathrm{dx}\)

A two-dimensional region can be integrated using double integrals. They enable us to, among other things, calculate the volume beneath a surface.

The integrals of a function in two variables over a region in R2, or the real number plane, are referred to as double integrals in mathematics. It is possible to write the double integral of a function of two variables, such as f(x, y), over a rectangular region as: R f (x, y) d A = R f (x, y) d x d y.

We know that by the property of integral \($\int u \mathrm{udv}=u v-v \int d u$\)

\($$\begin{aligned}& \mathrm{I}=4 \int_0^4 \ln |1+\mathrm{x}| \mathrm{dx}=\left[\mathrm{x} \ln (1+\mathrm{x})-\int \mathrm{x} \frac{.1}{1+\mathrm{x}} \mathrm{dx}\right]_0^4 \\& \mathrm{I}=4\left[\mathrm{x} \ln (1+\mathrm{x})-\int\left(1-\frac{1}{1+\mathrm{x}}\right) \mathrm{dx}\right]_0^4 \\& \mathrm{I}=4[\mathrm{x} \ln (1+\mathrm{x})-\mathrm{x}+\ln |1+\mathrm{x}|]_0^4 \\& \mathrm{I}=[4 \ln (5)-4+\ln (5)]-[0-0+0] \\& \mathrm{I}=4[5 \ln 5-4] \\& \mathrm{I}=20 \ln 5-16\end{aligned}$$\)

We have to evaluate the given double integral
