Answer: -1/1

Step-by-step explanation: The fraction, -1/1 or just -1, passes through the transactional point through the slope of the line, y=3x+5.

We need to perform the following steps:
1. Start with the function p(x) = 3x^2 + 4x + 2.
2. Use the average value formula:
  Average value = (1/(b-a)) * ∫(a to b) p(x)
  In this case, a = 1 and b = 7 because the interval is 1 ≤ x ≤ 7.
3. Integrate the function p(x) with respect to x over the interval (1 to 7):
   ∫(1 to 7) p(x) dx = ∫(1 to 7) (3x^2 + 4x + 2) dx
4. Calculate the integral:
  ∫(1 to 7) (3x^2 + 4x + 2) dx = [x^3 + 2x^2 + 2x] evaluated from 1 to 7
  Substitute 7 into the function: (7^3 + 2(7^2) + 2(7)) - Substitute 1 into the function: (1^3 + 2(1^2) + 2(1))
5. Simplify the expression:
  (343 + 2(49) + 2(7)) - (1 + 2 + 2) = 343 + 98 + 14 - 1 - 2 - 2 = 45
6. Now, calculate the average value:
  Average value = (1/(7-1)) * 450 = (1/6) * 450 = 75.

Therefore, the average value of the function p(x) = 3x^2 + 4x + 2 on the interval 1 ≤ x ≤ 7 is 75.

The standard deviation is 0.0692 and it means that on average, the sample statistic (X-bar) differs from the true population mean (mu) is 0.0692.

Given, In a recent poll, 46% of respondents claimed they would vote for the incumbent governor.

Assuming this is the true proportion of voters that would vote for the incumbent.

Let X be the number of people out of 50 that would vote for the incumbent.

We know that the standard deviation of the sampling distribution of X is:

σ = sqrt [p (1 - p) / n]

Where: p = proportion of success in the population,

n = size of the sample

σ = sqrt [0.46(1 - 0.46) / 50]

σ = sqrt [0.24 / 50]σ = sqrt [0.0048]

σ = 0.0692

Standard deviation of the sampling distribution of X is 0.0692.

Answer:

draw a straight line with a ruler through the points (0,0) and (3,1)

Step-by-step explanation:

since your equation is linear, you need to use a ruler to graph, put in 0 and 3 to get 0 and 1, respectively, and draw a line through the two points on a graph

Step-by-step explanation:

these are positive real numbers representing a size, which can only be positive.

direction is irrelevant.

the absolute value of an imaginary number is the distance of that number from the origin on the imaginary number plane. it does not matter in what direction.

the magnitude of a force is just the power involved, it does not say what direction.

the distance between 2 points - that is the same case as with the absolute value of the imaginary number. a distance is always positive independently of the direction.

The undefined term of the ray is line.

Undefined terms are those that are difficult to define. There isn't exactly a definition for such phrases. Think about the word "the." Although we frequently use the term "the," do we actually understand what it means? Another word that is difficult to define is "am." Although we can explain these phrases, we are unable to offer a definition. There are certain words in geometry that are more difficult to define.

A ray is a line that terminates at a single point in geometry and continues endlessly in the opposite direction.

We can understand why a ray is a defined concept since we can describe it using the geometric terms "line" and "point."

Ray: A ray is similar to a line, except that the line extends in just one direction to infinity, with a line segment on the opposite side.

The endpoint of a line is its terminus.

Two rays that originate at the same endpoint and move in opposition to one another are said to be opposing rays.

The series ∑ e^n / n^2, where n starts from 1 and goes to infinity, diverges. This means that the series does not have a finite sum and keeps growing indefinitely.

To determine the convergence or divergence of the series ∑ e^n / n^2, we can use various tests. One commonly used test is the comparison test.

When we compare the given series to a known series, such as the harmonic series or geometric series, we can see that the terms of the given series do not decrease or approach zero as n increases. In fact, the exponential term e^n grows exponentially, and the denominator n^2 increases at a much slower rate.

As a result, the terms of the series do not tend to zero, and we can conclude that the series diverges. In other words, the sum of the series goes to infinity as n approaches infinity. This indicates that the series does not have a finite sum and keeps growing indefinitely.

Therefore, the series ∑ e^n / n^2 diverges.

Answer:

R=2

Step-by-step explanation:

In order for the RLC oscillating circuit to decay to 1/10th of its initial value of charge in 50 cycles, a certain resistance (R) needs to be connected in series with a 200-mH inductor and a capacitor.

To determine the required resistance (R), we need to consider the decay of the RLC oscillating circuit over 50 cycles. The decay of the charge in the circuit is influenced by the combination of the inductor, capacitor, and the resistance. The resistance plays a crucial role in damping the oscillations and controlling the decay rate.

To calculate the required resistance, we would need more information such as the initial charge value, the frequency of the oscillations, or the specific values of the inductor and capacitor. Without these details, it is not possible to provide a specific value for the resistance (R) in this scenario. The resistance value will depend on the desired decay rate and the specific characteristics of the circuit components.

Given that

(2+i)²/(3+i)

On multiplying both numerator and the denominator with (3-i) then

⇛ [(2+i)²/(3+i)]×[(3-i)/(3-i)]

⇛ [(2+i)²(3-i)]/[(3+i)(3-i)]

⇛ [(2+i)²(3-i)]/[(3²-i²)

⇛ [(2+i)²(3-i)]/(9-i²)

⇛ [(2+i)²(3-i)]/[9-(-1)]

Since ,i² = -1

⇛ [(2+i)²(3-i)]/(9+1)

⇛ [(2+i)²(3-i)]/10

⇛ [{2²+i²+2(2)(i)}(3-i)]/10

⇛ (4+i²+4i)(3-i)/10

⇛ (4-1+4i)(3-i)/10

⇛ (3+4i)(3-i)/10

⇛ (9-3i+12i-4i²)/10

⇛ (9+9i-4(-1))/10

Since, i² = -1

⇛(9+9i+4)/10

The complement of set Q {-4, -3, -2} if the universal set is P {-5, -4, -3, -2, -1} is defined by:

¬Q = {-5, -1}

If we have a set A defined in an universal set U, we define the complement of A as all the elements of U that are not elements of A.

In this case we have the sets:

P = {-5, -4, -3, -2, -1}

Q = {-4, -3, -2}

Here we want to find the complement of Q in P, so P is the universal set for this problem.

Point: a cross-section that goes through the center of the sphere and creates a single point.

The optimal lenght of x and y are:

x = 30ft

y = 30ft

To solve this, we want to know the best lenght of x and y to get the maximum area.

Then, we know the perimeter of the pens: 120ft

The perimeter is the sum of all the sides:

Sinnce we have 2 sides of lenght x and 2 sides of length y

Also, we know how the area is calculated. Base times height:

Now, we know the perimeter he has is 120ft. Then, we can replace P = 120ft and solve for y:

Now we can replace y in the area equation:

Here we have a function of the area respect x.

Then, we want to find the maximum area possible. We know that the zeroes of the derivative of a function is where we can find maximums and minimums.

Then let's derivate the function of the area:

Now let's find the zero of the derivative:

This is the value of x that maximizes the area with a perimeter of 120ft.

Now let's find the value of y:

Then the maximum area is with a lenght of y = 30ft and x = 30ft.

The surface area of the rectangular pyramid is approximately 567.9 in².

What is rectangular pyramid?

A rectangular pyramid is a type of pyramid that has a rectangular base and four triangular faces that meet at a common vertex. The rectangular base of a rectangular pyramid can be any rectangle, meaning that the length and width can be different. The four triangular faces of a rectangular pyramid are congruent, which means they are the same size and shape. The height of the rectangular pyramid is the distance between the vertex and the center of the base. The surface area of a rectangular pyramid can be calculated by finding the area of each face and adding them together.

To find the surface area of the rectangular pyramid, we need to find the area of each face and add them together.

First, let's find the area of the rectangular base:

Area of base = length x width = 13 in x 17 in = 221 in²

Next, let's find the area of the larger triangular faces:

Area of each larger triangular face = (1/2) x base x height = (1/2) x 17 in x 11 in = 93.5 in²

Total area of both larger triangular faces = 2 x 93.5 in² = 187 in²

Finally, let's find the area of the smaller triangular face:

Area of smaller triangular face = (1/2) x base x height = (1/2) x 13 in x 12.3 in = 79.95 in²

Now, we can find the total surface area of the rectangular pyramid by adding the areas of all the faces:

Total surface area = area of base + area of both larger triangular faces + area of smaller triangular face

Total surface area = 221 in² + 187 in² + 79.95 in²

Total surface area = 488.95 in²

Therefore, the surface area of the rectangular pyramid is approximately 567.9 in².
