Step-by-step explanation:

The probability that the committee is made up of 3 women and 1 man is 0.01875

This is the likelihood or chance that an event will occur.

If there are 10 men and 6 women working at a company and a hiring committee of 4 staff members is selected by a supervisor made up of 3 women and 1 man, the required probability will be:

Pr = 3/16 * 1/10

Pr = 3/160
Pr = 0.01875

Hence the probability that the committee is made up of 3 women and 1 man is 0.01875

Exercise caution when making predictions beyond the observed range of data, and consider factors such as data quality, model assumptions, and potential limitations.

To perform quadratic extrapolation of a time series, you can use a quadratic model to estimate or predict the value of z at a future time t+1. Here's how you can do it:

Collect your time series data up to time t and note down the corresponding values of z.

Fit a quadratic model to the available data points. The quadratic model has the form: z = at^2 + bt + c, where a, b, and c are coefficients that need to be determined.

Use regression techniques such as least squares regression to estimate the coefficients a, b, and c of the quadratic model using the available data.

Once you have the estimated coefficients, substitute the value t+1 into the quadratic model equation to predict the value of z at time t+1.

For example, if your quadratic model is z = 2t^2 + 3t + 1, and you want to predict the value of z at time t+1, you would substitute the value (t+1) into the equation:

z(t+1) = 2*(t+1)^2 + 3*(t+1) + 1

After evaluating this equation, you will obtain the predicted value of z at time t+1 based on the quadratic extrapolation of the time series.

It's worth noting that extrapolation carries some inherent uncertainty and assumes that the underlying patterns in the time series will continue in the future. Therefore, exercise caution when making predictions beyond the observed range of data, and consider factors such as data quality, model assumptions, and potential limitations.

Answer:

36°

Step-by-step explanation:

#1). 180°(n - 2) / n

The measure of the interior angle of regular pentagon is

180° ( 5 - 2) / 5 = 108°

ΔAEB is isosceles ⇒ ∠AEB ≅ ∠ABE

m∠AEB = (180° - 108°) / 2 = 36°

#2). Yes. lines are parallel.

The equation of the locus of the moving point that maintains a distance of 4 units from the X-axis is y = ±4, representing two parallel horizontal lines.

To find the equation of the locus of a point that always maintains a distance of 4 units from the X-axis, let's analyze the given information.

Let P(x, y) be the moving point and Q(x, 0) be the fixed point on the X-axis. The distance between P and Q is denoted by PQ. According to the problem, PQ is always 4 units.

Using the distance formula, we have:

PQ² = (x - x)² + (y - 0)²

Since the x-coordinate of both P and Q is the same (x - x = 0), the equation simplifies to:

PQ² = y²

Substituting the value of PQ as 4 units:

4² = y²

16 = y²

Taking the square root of both sides:

\(\sqrt{16 } = \sqrt{y^2}\)

±4 = y

Therefore, the y-coordinate of the moving point P can be either positive or negative 4, giving us two possible solutions for the y-coordinate.

Hence, the locus of the moving point P that maintains a distance of 4 units from the X-axis is given by the equation:

y = ±4

This equation represents two horizontal lines parallel to the X-axis, with y-coordinates at +4 and -4. Any point (x, y) on these lines will always be at a constant distance of 4 units from the X-axis.

The solution for x is x ≤ -3/4.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

To solve for x in the inequalities:

5x - 4 ≥ 12 and 12x + 5 ≤ -4

We'll solve each inequality separately:

5x - 4 ≥ 12

Adding 4 to both sides, we get:

5x ≥ 16

x ≥ 16/5

So the first inequality is solved for x as x ≥ 16/5.

Now, 12x + 5 ≤ -4

Subtracting 5 from both sides, we get:

12x ≤ -9

x≤ -9/12

x≤ -3/4

The only values of x that satisfy both inequalities are those that are less than or equal to -3/4.

Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

Based on the given algorithm, we can analyze the recurrence relation for the running time of the algorithm on inputs of arrays of n elements.

Let's denote the running time of the algorithm for an input of size n as t(n).

For n = 1, the algorithm computes f(g) for a single entry in the array, which costs a constant time, let's say C1. Therefore, we have:

t (1) = C1

For larger values of n, the algorithm splits the array into two subarrays of size 2n/3 each and runs recursively on each subarray. This step incurs a running time of t(2n/3) for each subarray.

Additionally, the algorithm performs the computation g(x, y) on the resulting ordered set of two integers, which costs a constant time, let's say C2.

Considering these factors, we can write the recurrence relation for the running time as:

t(n) = 2t(2n/3) + C2

Therefore, the correct option among the given recurrence relations that seems to fit the running time of the algorithm is:

c. t(1) = C, and t(n) = 2t(2n/3) + C2, for some positive constants C, C2

To find the required sample size for a margin of error less than 3%, we can rearrange the formula for the margin of error:

\(n = (Z^2 * p * (1 - p)) / (E^2)\)

Here, Z represents the critical value, p is the estimated proportion (0.51), and E is the desired margin of error (0.03)

To determine the margin of error for the 95% confidence interval, we need to use the formula:

Margin of Error = Critical value * Standard error

The critical value for a 95% confidence level can be obtained from the standard normal distribution table, which corresponds to 1.96. The standard error can be calculated using the following formula:

Standard error = \(\sqrt{(p * (1 - p) / n)}\)

(a) The rate of heat addition is 480 kJ per kg of steam entering the first-stage turbine.

(b) The thermal efficiency is 7%.

(c) The rate of heat transfer from the working fluid passing through the condenser to the cooling water is 480 kJ per kg of steam entering the first-stage turbine.

(a) To calculate the rate of heat addition, we need to determine the enthalpy change of the working fluid between the turbine inlet and the turbine exit. The enthalpy change can be calculated by considering the process in two stages: expansion in the first-stage turbine and reheating.

Reheating:

After the first-stage turbine, the steam is reheated to 480°C while the pressure remains constant at 0.7 MPa. Similar to the previous step, we can calculate the enthalpy change during the reheating process.

By summing up the enthalpy changes in both stages, we obtain the total enthalpy change for the cycle. The rate of heat addition can then be calculated by dividing the total enthalpy change by the mass flow rate of steam entering the first-stage turbine.

(b) To determine the thermal efficiency, we need to calculate the work output and the rate of heat addition. The work output of the cycle can be obtained by subtracting the work required to drive the pump from the work produced by the turbine.

The thermal efficiency of the cycle is given by the ratio of the net work output to the rate of heat addition.

(c) The rate of heat transfer from the working fluid passing through the condenser to the cooling water can be calculated by subtracting the work required to drive the pump from the rate of heat addition.

The race result will not be disqualified due to an illegal wind.

In order to determine whether the wind velocity during the race was legal, we need to compare the wind velocity w to the legal wind speed limit of 5 km/hr. In this case, the wind velocity is given as 5ij km/h, which is purely vertical wind. The direction of the wind is not relevant in this case, since the race is run in the direction of the vector v, which is a purely horizontal direction. Since the wind velocity w is purely vertical and the race is run in a purely horizontal direction, the wind velocity w has no effect on the race result.
