The series solution corresponding to the indicial root Y=0 is given by Y(x) = x.

To solve the differential equation XY"-xy' + y = 0, we assume a series solution of the form Y(x) = Σᵢ aₙxⁿ.

Indicial Equation:

Substituting the series solution into the differential equation, we get XY" - xy' + y = Σᵢ aₙxⁿ(Xn(n-1) - nx + 1) = 0.

Equating the coefficients of like powers of x to zero, we obtain the indicial equation Xn(n-1) - nx + 1 = 0.

Indicial Roots:

The indicial equation is a quadratic equation. To find the roots, we solve for n using the quadratic formula:

n = (-(-1) ± √((-1)² - 4X(1)(X)))/(2X) = (1 ± √(1 - 4X²))/(2X).

The indicial roots are the values of n that satisfy the indicial equation. Since we are given the indicial root Y = 0, we substitute n = 0 into the indicial equation:

(0 - 0 + 1) = 0,

which is true. Hence, n = 0 is an indicial root.

Recurrence Relation:Since the indicial root is 0, we have one recurrence relation of the form: Cₖ₊₁(k + r + 1) - cₖz(k + r) = 0.

Solution Corresponding to Indicial Root:

To determine the series solution corresponding to the indicial root Y = 0, we substitute n = 0 into the assumed series solution:

Y(x) = Σᵢ aₙxⁿ = a₀.

Thus, the series solution corresponding to the indicial root Y = 0 is Y(x) = x.

Step-by-step explanation:

(a) A normal quantile plot of the data is illustrated below.

(b) There are some slight deviations from the line, particularly for the data points at the extremes of the distribution (68 and 82 inches).

In this case, we have the heights of 7 NBA players: 68, 69, 78, 82, 75, 73, and 80 inches. To construct the normal quantile plot, we first calculate the mean and standard deviation of the data:

Mean = (68 + 69 + 78 + 82 + 75 + 73 + 80) / 7 = 75.43

Standard deviation = 5.98

Next, we calculate the z-scores for each data point:

z1 = (68 - 75.43) / 5.98 = -1.24

z2 = (69 - 75.43) / 5.98 = -1.07

z3 = (78 - 75.43) / 5.98 = 0.43

z4 = (82 - 75.43) / 5.98 = 1.09

z5 = (75 - 75.43) / 5.98 = -0.07

z6 = (73 - 75.43) / 5.98 = -0.41

z7 = (80 - 75.43) / 5.98 = 0.75

We can then plot the z-scores against the corresponding quantiles of a standard normal distribution. The z-score of -1.24 corresponds to the 10th percentile of the standard normal distribution, while the z-score of 1.09 corresponds to the 86th percentile.

The 90% confidence interval for the difference between the proportions of college graduates and individuals with some college who believe in the theory of evolution is (0.022, 0.220)

The sample size of respondents with some college education is 325, and 133 of them believe in the theory of evolution. The sample size of respondents who were college graduates is 228, and 121 of them believe in the theory of evolution.

Now, the sample proportions are:p1= 133/325 = 0.410p2 = 121/228 = 0.531The point estimate of the difference in proportions is:p1 - p2 = 0.531 - 0.410 = 0.121

To calculate the standard error of the sampling distribution of the difference of two proportions, use the following formula:\($$SE = \sqrt{ \frac{p_1(1-p_1)}{n_1} + \frac{p_2(1-p_2)}{n_2}}$$\)

Substituting the values, we get,\($$SE = \sqrt{ \frac{0.410(1-0.410)}{325} + \frac{0.531(1-0.531)}{228}}$$\)

Solving the above expression, we get,\($$SE = 0.0489$$\)

Using the formula of the confidence interval,\($$\text{Confidence Interval} = \text{point estimate} ± \text{margin of error}$$\)

Substituting the values,\($$\text{Confidence Interval} = 0.121 ± 1.645 \times 0.0489$$\)

Now, solving the above expression, we get the confidence interval as:\($$(0.022, 0.220)$$\)

Answer:

Undefined

Step-by-step explanation:

As you try to evaluate the expression, the denominator shows a proplem.-3+3 is equal to 0. So the expression is 2/0. The problem is, dividing anything by zero is undefined. This means that the entire expression is undefined.

Based on the evaluation of the conditions, the output "x < 0 and z > 0" will be printed. Therefore, the correct answer is B. x < 0 and z > 0.

The correct indentation of the statement would be as follows:

if (x > 0)

if (y > 0)

System.out.println("x > 0 and y > 0");

else if (z > 0)

System.out.println("x < 0 and z > 0");

Given that x = 1, y = -1, and z = 1, let's evaluate the conditions:

The first if statement checks if x > 0, which is true since x = 1.

Since the condition in the first if statement is true, we move to the inner if statement, which checks if y > 0. However, y = -1, so this condition is false.

The inner if statement is followed by an else if statement that checks if z > 0. Since z = 1, this condition is true.

The probability of 180 or fewer doctors in the sample agreeing that they would recommend the painkiller, if the TV claim that two out of every three doctors recommend it is correct, is approximately 0.233 or 23.3%.

Let's define a success as a doctor recommending the painkiller. According to the TV claim, the probability of success is p = 2/3, and the probability of failure is q = 1 - p = 1/3.

The sample size is n = 300, and the number of successes in the sample is x = 180.

We can use the binomial probability formula to calculate the probability:

P(X ≤ 180) =  \(\[\sum_{i=0}^{180} {300 \choose i} \left(\frac{2}{3}\right)^i \left(\frac{1}{3}\right)^{300-i}\]\)

Calculating this probability using statistical software or a binomial probability calculator, we find that P(X ≤ 180) is approximately 0.233 or 23.3%.

Therefore, if the TV claim is correct, there is a 23.3% probability of observing 180 or fewer doctors in the sample agreeing that they would recommend the painkiller.

Step-by-step explanation:

On average, a customer spends approximately 1.16 minutes waiting time on hold before they can start speaking to a representative.

To find the average waiting time for a customer on hold before they can start speaking to a representative, we need to consider both the arrival rate of calls and the average service time of the staff members.

Given:

9 staff members taking calls.

On average, one call arrives every 5 minutes (standard deviation of 5 minutes).

Each staff member spends on average 18 minutes with each customer (with a standard deviation of 27 minutes).

To calculate the average waiting time, we need to use queuing theory, specifically the M/M/c queuing model. In this model:

"M" stands for Markovian or memoryless arrival and service times.

"c" represents the number of servers.

In our case, we have an M/M/9 queuing model since we have 9 staff members.

The average waiting time for a customer on hold is given by the following formula:

Waiting time = (1 / (c * (μ - λ))) * (ρ / (1 - ρ))

Where:

c = number of servers (staff members) = 9

μ = average service rate (1 / average service time)

λ = average arrival rate (1 / average interarrival time)

ρ = λ / (c * μ)

First, let's calculate the average arrival rate (λ):

λ = 1 / (average interarrival time) = 1 / 5 minutes = 0.2 calls per minute

Next, calculate the average service rate (μ):

μ = 1 / (average service time) = 1 / 18 minutes = 0.0556 customers per minute

Now, calculate ρ:

ρ = λ / (c * μ) = 0.2 / (9 * 0.0556) ≈ 0.407

Finally, calculate the waiting time:

Waiting time = (1 / (c * (μ - λ))) * (ρ / (1 - ρ))

= (1 / (9 * (0.0556 - 0.2))) * (0.407 / (1 - 0.407))

≈ 1.16 minutes

Therefore, on average, a customer spends approximately 1.16 minutes waiting on hold before they can start speaking to a representative.
