Using the properties of arithmetic sequence , we calculate

a) 100 seats in the first row (b) 40 rows are required (c) 22 more seats in each row (d) 958 seats in the last row.

The overlap of any two doubly infinite arithmetic progressions seems to be either empty or another arithmetic progression, according to the Chinese remainder theorem.

If every pair of advancements in a family of twice infinite arithmetic progressions has a non-empty intersection, then there is a number that connects all of the pairs; consequently, an infinite arithmetic progression is a member of the Helly family.

However, rather than being an unending progression in and of itself, the intersection of an infinite number of infinite arithmetic progressions might be a particular number.

We know that the AP has the total number of seats between 18 000 and 22 500.

So if we take first term as 100 common difference as 22 and 40 rows we get :

sum =  \(\frac{40}{2} [2\times 100+(40-1)22] = 21160\)

Therefore the number of seats in the arena matches the required description.

and the last row will have 100+(39)22 = 968 seats.

In this problem, a researcher wants to estimate the number of households with two cars with 95% confidence and a margin of error of 5%. The researcher also knows that a previous study showed that 22% of households had two cars. The possible answers are 4, 339, and 186.

To answer this question, we need to use the formula for sample size calculation: n = (Z^2 * p * q) / E^2, where n is the sample size, Z is the Z-score for the desired level of confidence (in this case, 1.96 for 95% confidence), p is the estimated proportion of the population with the characteristic of interest (in this case, 0.22), q is the complement of p (q = 1 - p), and E is the desired margin of error (in this case, 0.05). Plugging in these values gives us n = (1.96^2 * 0.22 * 0.78) / 0.05^2, which simplifies to n = 186.

Therefore, the correct answer is (c) 186. This means that the researcher needs to survey 186 households to estimate the number of households with two cars with 95% confidence and a margin of error of 5%.

Answer:

The answer is 8,000 k/cm³

This gives us a total of 1,583,616 ft-lbs of work required to pump the water out of the pool.

Amount is a numerical value that refers to the total sum of money or other type of payment due. It is used to quantify the size of a transaction, the cost of goods or services, or any other type of financial transaction. Amounts can be expressed in a variety of different currencies, and they can be negative (owing) or positive (owed).

To calculate the amount of work required to pump all the water from the rectangular swimming pool into a drain at the top edge, we must first calculate the volume of the water in the pool. Volume is calculated by multiplying the length, width, and depth of the pool, which in this case is 20 ft x 20 ft x 8 ft = 3,200 cubic ft. Since the pool is filled to 1 ft below the top, the volume of water is 3,200 ft3 - 20 ft3 = 3,180 ft3.

Next, we must calculate the weight of the water, which is the volume multiplied by the weight density of water (62.4 lb/ft3). The weight of the water in the pool is 3,180 ft3 x 62.4 lb/ft3 = 197,952 lbs.

Finally, to calculate the amount of work required to pump the water from the pool into a drain at the top edge, we must multiply the weight of the water (197,952 lbs) by the height of the drain (8 ft). This gives us a total of 1,583,616 ft-lbs of work required to pump the water out of the pool.

The solutions of the given equation in the interval [0, 2π) are: x = 0, x = π/2, x = π, x = 3π/2

solve the equation sin(2x)cos(x) = 0 in the interval [0, 2π).

First, we'll use the double-angle formula to simplify the equation. The double-angle formula for sine is:

sin(2x) = 2sin(x)cos(x)

Now, substitute this into the given equation:

2sin(x)cos(x)cos(x) = 0

This simplifies to:

2sin(x)cos^2(x) = 0

Now, we can solve the equation by setting each factor equal to zero:

1) sin(x) = 0
2) cos^2(x) = 0 or cos(x) = 0

For the first case (sin(x) = 0), the solutions within the interval [0, 2π) are:

x = 0, x = π

For the second case (cos(x) = 0), the solutions within the interval [0, 2π) are:

x = π/2, x = 3π/2

So, the solutions of the given equation in the interval [0, 2π) are:

Answer:

\(b=\sqrt{1575}\) ≈ 39.7ft

Step-by-step explanation:

The Pythagorean theorem:

\(a^{2}+ b^{2}= c^{2}\)

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)

First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.

\(45^{2}+ b^{2}= 60^{2}\)

\(2025+b^{2} =3600\)

To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

\(b^{2} =1575\)

\(b=\sqrt{1575}\) ≈ 39.7ft

a) The autocovariance of xt depends only on the time difference h, and not on the specific time t and xt is weakly stationary

b)  The joint distribution of xt depends on the specific time t, and xt is not strictly stationary.

a) To prove that xt is weakly stationary, we need to show that its mean and autocovariance are both independent of time.

First, let's calculate the mean of xt:

E(xt) = E(sin(2πUt))

Since U has a uniform distribution on (0,1), we know that E(U) = 1/2. Therefore,

E(xt) = E(sin(2πUt)) = sin(2πE(Ut)) = sin(πt) = 0

So the mean of xt is zero, which is independent of time.

Now let's calculate the autocovariance of xt:

Cov(xt, xt+h) = E[(sin(2πUt) - 0)(sin(2πU(t+h)) - 0)]

= E[sin(2πUt)sin(2πU(t+h))]

We can use the identity sin(a)sin(b) = (1/2)(cos(a-b) - cos(a+b)) to expand this expression:

Cov(xt, xt+h) = (1/2)E[cos(2πhU) - cos(2π(t+h)U) - cos(2πtU) + cos(2πhU)]

Since E(cos(2πhU)) = E(cos(2π(t+h)U)) = E(cos(2πtU)) = 0 (due to the symmetry of the cosine function over [0,1]), we have:

Cov(xt, xt+h) = (1/2)E[cos(2πhU) + cos(2πhU)]

= E[cos(2πhU)]

Using the identity E[cos(2πhU)] = cos(2πhE[U]) = cos(πh), we get:

Cov(xt, xt+h) = cos(πh)

Therefore, the autocovariance of xt depends only on the time difference h, and not on the specific time t. Thus, xt is weakly stationary.

b) To prove that xt is not strictly stationary, we need to find at least one time shift for which the joint distribution of the series is different from the original joint distribution.

Consider the joint distribution of x1 and x2:

P(x1 = sin(2πU), x2 = sin(2πU(2))) = P(U=u)P(U=2u) = 0

since U has a continuous uniform distribution.

However, if we shift the time by 1 unit, the joint distribution of x2 and x3 becomes:

P(x2 = sin(2πU(2)), x3 = sin(2πU(3))) = P(U=2u)P(U=3u) ≠ 0

since U has a continuous distribution.

Therefore, the joint distribution of xt depends on the specific time t, and xt is not strictly stationary.

A line, line segment, or ray that divides an angle into two congruent angles is called an angle bisector.

What are supplementary angles example?

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly, complementary angles add up to 90 degrees.

What do you mean by angle bisector?

If the angle is divided by the line and the angle is divided such that the angles are equal to each other then the line is called the angle bisector.

The word congruent means equal of the things. In this, the angles are congruent to each other which means the angles are equal to each other.

Therefore, since a movement is set to start at T minus 80, the move will be completed at T plus 10 seconds.

The amount of rotations a shape can undergo around its center before returning to its initial position is referred to as the order of rotation in mathematics and geometry. It is also referred to as a shape's circular symmetry. A circle, for instance, has an order of rotation of infinite because it can be rotated indefinitely around its center without changing how it appears. A cube has an order of rotation of four because it will remain the same in shape whether it is rotated 90, 180, 270, or 360 degrees around its center.

given

At T minus 80 seconds, or 80 seconds prior to liftoff, the move is slated to start.

We must multiply the duration of the maneuver by the beginning time to determine the time at which it will be finished.

The move is estimated to take 1 and a half minutes. Since there are 60 seconds in a minute, we can change this to seconds by multiplying it by 60:

1 and a half minutes is equal to 1.5 minutes, 1.5 minutes multiplied by 60 seconds is equal to 90 seconds.

The move lasts 90 seconds as a result.

We multiply the duration of the move (90 seconds) by the start time (T minus 80 seconds) to determine the time at which the maneuver will be finished:

The move will be finished in T minus 80 seconds plus 90 seconds.

By adding the integers, we can make this simpler:

When the move is finished, the time will be T minus 80 seconds + 90 seconds + T plus 10 seconds.

Therefore, since a movement is set to start at T minus 80, the move will be completed at T plus 10 seconds.
