Answer: look at the images for the answer and the solution

Step-by-step explanation:

The mean of the data values is 17. The median of the data values is 18.

To find the mean of a set of data values, we sum up all the values and divide by the total number of values. In this case, the sum of the data values is 10 + 20 + 21 + 14 + 18 + 19 = 102. Since there are 6 data values, the mean is 102/6 = 17.

The median is the middle value of a set of data when it is arranged in ascending or descending order. In this case, the data values arranged in ascending order are 10, 14, 18, 19, 20, 21. Since there are 6 values, the middle two values are 18 and 19. Therefore, the median is 18.

Here's a MATLAB code that calculates the total sum of the first 750 terms of the series using only for loops.

```matlab

% Initialize the total sum

totalSum = 0;

% Iterate from n = 1 to n = 750

for n = 1:750

   % Calculate the term of the series for the current n

   term = 1/n;

   % Add the current term to the total sum

   totalSum = totalSum + term;

end

% Display the total sum

The wavelengths of the three components of the Hα line due to the magnetic field in a typical sunspot are as follows:

1. Central Line: The wavelength of the central line remains unchanged and is equal to the original wavelength of the Hα line, which is 6562.81 Å.

2. Offset Line 1: The first offset line occurs at a higher frequency and shorter wavelength than the central line. It is given by λ = λ0 - Δλ, where Δλ is the change in wavelength. In this case, Δλ is determined by the Zeeman effect equation: Δλ = eB/(4πm_e), where e is the charge of an electron, B is the magnetic field strength, and m_e is the electron mass. By substituting the values and using the relationship between wavelength and frequency (λ = c/f, where c is the speed of light), the corresponding wavelength of the first offset line can be calculated.

3. Offset Line 2: The second offset line occurs at a lower frequency and longer wavelength than the central line. It is given by λ = λ0 + Δλ, where Δλ is determined as explained above. By substituting the values and using the relationship between wavelength and frequency, the corresponding wavelength of the second offset line can be calculated.

Answer: d.

2x + x = 180: 60°and 120°

Step-by-step explanation:

Let x= one of the supplements.  (smaller)

As per given , measure of second angle = 2x

We know that,

The sum of two supplements = 180 degrees

Then,

smaller angle + larger angle =180°

i.e. x+2x = 180°

3x= 180°

x=60°

then, 2x = 2 (60°) = 120°

hence, the correct option is d.

2x + x = 180: 60°and 120°

(a) To find the value of z 0.03, we use a standard normal distribution table or calculator. From the table, we find that the z-score corresponding to a right-tailed probability of 0.03 is approximately 1.88. Therefore, z 0.03 = 1.88.

(b) Given a random sample of size n = 36 from a population with standard deviation σ = 12 and sample mean X = 75, we can construct confidence intervals for the population mean μ using the t-distribution since the population standard deviation is unknown.

i. To construct a 90% confidence interval for μ, we first need to find the t-value with degrees of freedom (df) = n - 1 and a cumulative probability of (1 - 0.90)/2 = 0.05 in each tail of the distribution. Using a t-distribution table or calculator with df = 35, we find that the t-value is approximately 1.69.

The margin of error (ME) is then calculated as ME = tα/2 * (σ/√n), where tα/2 is the critical value for the desired level of confidence, σ is the population standard deviation, and n is the sample size.

Substituting the values, we get ME = 1.69 * (12/√36) = 6.08

The confidence interval is then calculated as (X - ME, X + ME) or (75 - 6.08, 75 + 6.08), which simplifies to (68.92, 81.08). Therefore, we are 90% confident that the true population mean falls within this interval.

ii. To construct a 96% confidence interval for μ, we follow similar steps as above but with a different t-value and margin of error.

Using a t-distribution table or calculator with df = 35, we find that the t-value is approximately 2.03 for a cumulative probability of (1 - 0.96)/2 = 0.02 in each tail of the distribution.

The margin of error is then calculated as ME = 2.03 * (12/√36) = 7.32

The confidence interval is (X - ME, X + ME) or (75 - 7.32, 75 + 7.32), which simplifies to (67.68, 82.32). Therefore, we are 96% confident that the true population mean falls within this interval.

Billy's health score go down  by 75% if his sugar resources are quadrupled

Let the amount of sugar in Billy's kitchen be denoted by S and the number of cookies he can bake be denoted by C. Let his health score be denoted by H. Then we have the following relationships:

C ∝ S (directly proportional)

C ∝ 1/H (inversely proportional)

Combining these two relationships, we get:

C ∝ S/H

If S is quadrupled, then C will also quadruple according to the first relationship. However, H will decrease by some percentage x according to the second relationship. To find x, we can use the fact that C is proportional to S/H:

C = k*S/H

where k is a constant of proportionality. If S is quadrupled, then C will also quadruple, so we have:

4C = k4S/H

C = kS/(H/4)

This tells us that if S is quadrupled, then C will be divided by H/4. In other words, C/H will be divided by 4. So, the percentage decrease in H can be found as follows:

C/H → (C/H)/4 = (S/H)/(4/k) → x = 100%*(1 - 1/4) = 75%

Therefore, if Billy's sugar resources are quadrupled, his health score will go down by 75%.

When the number of ounces is 9, the cost per ounce would be 40 cents. To solve , we can use the concept of inverse variation, which states that two variables are inversely proportional if their product remains constant.

Let's denote the cost per ounce as C and the number of ounces as N. According to the problem, we know that when N = 6, C = 60 cents per ounce. Using the inverse variation equation, we have: C × N = k, where k is the constant of variation. Substituting the given values, we get: 60 × 6 = k; k = 360.

Now, we can find the cost per ounce when N = 9: C × 9 = 360. Dividing both sides by 9, we have: C = 360 / 9; C = 40. Therefore, when the number of ounces is 9, the cost per ounce would be 40 cents.

The correct choice is:

A. The unique solution is w = -13.25, y = 0.25, and z = 3.75.

To solve the system using matrix reduction, let's write the system of equations in matrix form:

[A|B] = [w x y z | C]

The augmented matrix is:

[1 1 -1 -6 | -5]

[2 3 2 1 | 12]

[2 1 2 5 | 2]

Now, we'll perform row operations to reduce the matrix to row-echelon form:

R2 = R2 - 2R1

[1 1 -1 -6 | -5]

[0 1 4 13 | 22]

[2 1 2 5 | 2]

R3 = R3 - 2R1

[1 1 -1 -6 | -5]

[0 1 4 13 | 22]

[0 -1 4 17 | 12]

R3 = R3 + R2

[1 1 -1 -6 | -5]

[0 1 4 13 | 22]

[0 0 8 30 | 34]

Now, let's perform back substitution to solve for the variables:

R3 = R3/8

[1 1 -1 -6 | -5]

[0 1 4 13 | 22]

[0 0 1 3.75 | 4.25]

R2 = R2 - 4R3

[1 1 -1 -6 | -5]

[0 1 0 0.25 | 12.5]

[0 0 1 3.75 | 4.25]

R1 = R1 + R3

[1 1 0 -2.25 | -0.75]

[0 1 0 0.25 | 12.5]

[0 0 1 3.75 | 4.25]

R1 = R1 - R2

[1 0 0 -2.5 | -13.25]

[0 1 0 0.25 | 12.5]

[0 0 1 3.75 | 4.25]

Now, we have the row-echelon form of the matrix. The last column represents the values of the variables w, x, y, z.

From the reduced matrix, we can see that w = -13.25, x = 12.5, y = 0.25, and z = 3.75.

Therefore, the unique solution to the system is w = -13.25, x = 12.5, y = 0.25, and z = 3.75.

The most appropriate inference procedure for the researchers to use to analyze the results is a matched-pairs t-interval for a population mean difference.

A matched-pairs t-interval for a population mean difference is suitable for this study because it involves comparing the pretest and posttest scores of the same individuals.

The researchers are interested in determining whether there is a significant difference in the number of correct answers before and after the adult reading program.

By using a matched-pairs t-interval, the researchers can analyze the mean difference in scores and determine the range within which the true population mean difference is likely to fall. This inference procedure takes into account the paired nature of the data, accounting for individual differences and increasing the precision of the estimate.

It is important to use this procedure as it considers the correlation between the pretest and posttest scores for each individual, providing a more accurate assessment of the program's effectiveness.
