Step-by-step explanation:

At least 99% confidence that the sample percentage is inside 0.03 of the absolute proportion is required for 1844 residents.

Choose p = 0.5 since the previous estimate of population percentage is uncertain.

E = 0.03 is the margin of error.

A 99% confidence interval requires the following crucial value: \(z_{a/2}\) = 2.576

The act of deciding how many observations or repetitions to incorporate into a statistical sample is known as sample size determination.

The sample size,

n = 0.5 × (1 - 0.5) × (\(z_{a/2}\) ÷ E)²

n = 0.25 × (2.576 ÷ 0.03)²

n = 1843.27 ≈ 1844

As a result, the needed sample size is 1844.

Answer:

x = 92/11

Step-by-step explanation:

10x + 1 + 12x - 5 = 180

*group the like terms*

(10x + 12x) + (1-5) = 180

*simplify*

22x - 4 = 180

*add four on both sides to cancel out -4*

*simplify*

22x = 184

*divide both sides by 22 to cancel out the quantity and solve for x*

÷22 ÷22

w = √2 (cos(π/4) + i sin(π/4)) = √2 (1/√2 + i/√2) = 1 + i

z = 2 (cos(π/2) + i sin(π/2)) = 2i

Then

w - z = (1 + i) - 2i = 1 - i

so that

|w - z| = √(1² + (-1)²) = √2

and

arg(w - z) = -π/4

In polar form, we have

w - z = √2 (cos(-π/4) + i sin(-π/4)) = √2 (cos(π/4) - i sin(π/4))

b) 14:28

Step-by-step explanation:

y(x) = tan(x + C) where C is an arbitrary constant of integration. Thus, the equilibrium solutions are y = 1 and y = -1. The non-equilibrium solutions are the values of y that make y' not equal to 0.

y(x) = tan(x + C)

Where C is an arbitrary constant of integration.

The solution y(x) = tan(x + C) is a family of functions indexed by the arbitrary constant C. The constant C cannot be determined from the information given in the problem, and so the general solution contains all possible specific solutions.

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by

Expression; \(\rm \dfrac{4+2i}{8-3i}\)

A complex conjugate is formed by changing the sign between two terms in a complex number i.e. a+ ib has conjugate a-ib and a- ib has conjugate like a+ ib.

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

\(=\rm \dfrac{4+2i}{8-3i}\\\\= \rm \dfrac{4+2i}{8-3i}\times \dfrac{8+3i}{8+3i}\\\\= \dfrac{(4+2i) \times (8+3i)}{(8)^2-(-3i)^2}\\\\= \dfrac{32+12i+16i+6i^2}{64+9}\\\\=\dfrac{32+28i+6i^2}{73}\)

Hence, The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).

Answer:

Where is the question?

Step-by-step explanation:

At the bus station, there are eight lines for arriving passengers, each staffed by a single worker. The arrival rate for passengers is 124 per hour, which means the arrival rate per minute is 124/60 = 2.067 passengers per minute. Each passenger takes an average of 3 minutes for a worker to process, so the service rate per worker is 1/3 = 0.333 customers per minute.

Since there are eight workers, the combined service rate for all workers is 8 * 0.333 = 2.664 customers per minute. The coefficient of variation for arrival time is 1.4, and the coefficient of variation for service time is 1.

To find the average number of customers in the queue, we can use the formula:

Lq = (Ca^2 + Cs^2) * (λ^2) / (2 * (µ - λ))

Where Lq is the average number of customers in the queue, Ca is the coefficient of variation for arrival time, Cs is the coefficient of variation for service time, λ is the arrival rate, and µ is the service rate.

Lq = (1.4^2 + 1^2) * (2.067^2) / (2 * (2.664 - 2.067))
Lq = (1.96 + 1) * (4.276) / (2 * 0.597)
Lq ≈ 7.34 customers in the queue

To find the average time a customer spends in the queue, we can use the formula:

Wq = Lq / λ

Wq = 7.34 / 2.067
Wq ≈ 3.55 minutes

On average, customers spend approximately 3.55 minutes in the queue.

The main answer to the question is: None of these alternatives is correct. If the mean of a normal distribution is negative, the variance must not be negative. The explanation to support the answer is given below:

Normal distribution is a statistical distribution that depicts how values are dispersed in a dataset. It is also known as Gaussian distribution or bell curve because of its bell-shaped pattern. It is described by two parameters, i.e., mean and standard deviation.The mean of a normal distribution specifies the location of the center of the distribution. The variance of a normal distribution indicates the amount of variation from the mean. Variance is always positive, no matter whether the mean is positive or negative.

Therefore, if the mean of a normal distribution is negative, the variance must not be negative.Hence, none of these alternatives is correct. If the mean of a normal distribution is negative, the variance must not be negative.

Step-by-step explanation:

To find which equation is correct, first, let's find a similar point of Figure J and Figure K.

As you can see, Figure J was enlarged by a SF of 2.5 because -3 x 2.5 = -7.5, and -2 x 2.5 = -5.
