The required, Mmusi borrowed R3000 from Aggie as per the given conditions.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan.

Amount = Principal [1 + rate×time]

Let's call the amount Mmusi borrowed from Aggie "P".

After two years, he has to pay back
= P + P * 18% * 2
= P + 0.18 * P * 2
= P + 0.36P
= 1.36P

So if he has to pay back R4080, we can set up an equation to solve for P:

1.36P = 4080

To find P, we can divide both sides by 1.36:

P = 4080 / 1.36 = 3000

So Mmusi borrowed R3000 from Aggie.

Answer:

56.5 For Acellus Users

Step-by-step explanation:

Step 1. 2 x 3.14(pi) x radius(3) x height(3)

Step 2. Once added up should equal 56.5

Remember 2 x 3.14 x 3 x 3 = 56.5

(i) The dynamic programming matrix with the min cost entries for the given strings is as follows: ''1 2 1 2 3; 2 1 2 1 2; 3 2 1 2 3; 4 3 2 1 2''.  (ii) The min cost solutions by tracing back the matrix entries from bottom right are: Substitute 'a' at position 2 with 'b', Substitute 'a' at position 1 with 'a'.

(i) To create the dynamic programming matrix for string edit, we can use the Levenshtein distance algorithm. The matrix will have the alphabets of string X along the rows and the alphabets of string Y along the column entries.

First, let's create the initial matrix:

```

     ''  b   a   b   b

  ---------------------

'' |  0   1   2   3   4

a  |  1

b  |  2

a  |  3

b  |  4

```

In this matrix, the blank '' represents the empty string.

To calculate the min cost entries, we will use the following rules:

1. If the characters in the current cell match, copy the cost from the diagonal cell (top-left).

2. If the characters don't match, find the minimum cost among three neighboring cells: the left cell (insertion), the top cell (deletion), and the top-left cell (substitution). Add 1 to the minimum cost and place it in the current cell.

Let's calculate the min cost for two entries in the matrix:

1. For the cell at row 'a' and column 'b':

 The characters 'a' and 'b' don't match, so we need to find the minimum cost among the neighboring cells.

     - Left cell: The cost is 2 (from the previous row).

  - Top cell: The cost is 1 (from the previous column).

  - Top-left cell: The cost is 0 (from the previous row and column).

  The minimum cost is 0. Since the characters don't match, we add 1 to the minimum cost. Thus, the min cost for this cell is 1.

2. For the cell at row 'b' and column 'b':

  The characters 'b' match, so we copy the cost from the top-left diagonal cell.

  The min cost for this cell is 0.

We can continue calculating the min cost entries for the rest of the cells in a similar manner.

(ii) To trace back the matrix entries from the bottom right and calculate the min cost solutions, we start from the bottom-right cell and move towards the top-left cell.

Using the matrix from part (i), let's trace back the entries:

Starting from the cell at row 'a' and column 'b' (cost 1), we compare the neighboring cells:

- Left cell: Cost 2

- Top cell: Cost 3

- Top-left cell: Cost 0

The minimum cost is in the top-left cell, so we choose that path. We have performed a substitution operation, changing 'a' to 'b'. We move to the top-left cell.

Continuing the process, we compare the neighboring cells of the current cell:

- Left cell: Cost 1

- Top cell: Cost 2

- Top-left cell: Cost 0

Again, the minimum cost is in the top-left cell. We have performed a substitution operation, changing 'b' to 'a'. We move to the top-left cell.

We repeat this process until we reach the top-left cell of the matrix.

The complete sequence of operations to transform string X into string Y is as follows:

1. Substitute 'a' at position 2 with 'b': "a b a b" → "a b b b"

2. Substitute 'a' at position 1 with 'a': "a b b b" → "b a b b"

By following this sequence, we achieve the transformation from string X to string Y with the minimum cost.

Step-by-step explanation:

The normal probability plot suggests the data is approximately normally distributed. The sample standard deviation of given data is 3.13. The 95% confidence interval for the population standard deviation is (1.85, 6.28). The investment manager's desire for a population standard deviation below 6% is validated by the confidence interval.

To construct a normal probability plot, we first need to sort the data in ascending order:

6.6, 6.7, 8.7, 9.6, 10.0, 10.3, 11.3, 12.4, 12.4, 13.8, 14.9, 15.9

Then we can plot the ordered data against the expected values of a normal distribution with the same mean and standard deviation as the sample. The plot shows that the points follow a roughly straight line, which suggests that the data is roughly normally distributed.

To determine the sample standard deviation, we can use the formula:

s = sqrt[(∑(xi - x)²) / (n - 1)]

where xi is the rate of return for each year, x is the sample mean, and n is the sample size.

Sample mean:

x = (13.8 + 15.9 + 10.0 + 12.4 + 11.3 + 6.6 + 9.6 + 12.4 + 10.3 + 8.7 + 14.9 + 6.7) / 12 = 11.433

Sample standard deviation:

s = sqrt[((13.8 - 11.433)² + (15.9 - 11.433)² + ... + (6.7 - 11.433)²) / (12 - 1)]

= 3.059

Therefore, the sample standard deviation is 3.059.

To construct a 95% confidence interval for the population standard deviation of the rate of return, we can use the formula:

CI = [(n - 1) * s² / χ²(α/2, n-1), (n - 1) * s² / χ²(1-α/2, n-1)]

where n is the sample size, s is the sample standard deviation, χ² is the chi-square distribution, and α is the level of significance (1 - confidence level).

For a 95% confidence level and 11 degrees of freedom (n - 1), α = 0.05/2 = 0.025. From the chi-square distribution table with 11 degrees of freedom, we can find the critical values as follows:

χ²(0.025, 11) = 2.201 and χ²(0.975, 11) = 23.337

Plugging in the values, we get:

CI = [(12 - 1) * 3.059² / 23.337, (12 - 1) * 3.059² / 2.201]

= [1.946, 26.557]

Therefore, we can say with 95% confidence that the population standard deviation of the rate of return is between 1.946 and 26.557.

The investment manager wants to have a population standard deviation for the rate of return below 6%. The confidence interval (1.946, 26.557) does not validate this desire, as it includes values above 6%. Therefore, based on the sample data, the investment manager cannot be confident that the population standard deviation is below 6%.

(b) The conclusion would make if a 0.05 is rejected because the p-value (0.0016) is less than the significance level.

If using a significance level of 0.01, the null hypothesis would still be rejected because the p-value is less than 0.01.

(a) The p-value of 0.0016 indicates that the probability of obtaining a sample mean hemoglobin level of 11.3 g/dl or lower, assuming that the true population mean is 12 g/dl (or higher), is only 0.0016. This suggests that the observed difference between the sample mean and the hypothesized population mean is statistically significant and unlikely to be due to chance alone.

(b) If using a significance level of 0.05, the null hypothesis (that the true population mean is 12 g/dl or higher) would be rejected because the p-value (0.0016) is less than the significance level. Therefore, it can be concluded that the sample provides evidence that the true population mean hemoglobin level is lower than 12 g/dl.

If using a significance level of 0.01, the null hypothesis would still be rejected because the p-value is less than 0.01. In this case, the evidence is even stronger, and the conclusion that the true population mean is lower than 12 g/dl would be even more robust.

Step-by-step explanation:

Step 1 - Make the two equations equal the same:

3x + y = 4

2x + y = 5

Add 1 to the first equation:

3x + y + 1 = 5

2x + y = 5

3x + y + 1 = 2x + y

Step 2 - Subtract 2x from both sides to isolate y:

3x + y + 1 = 2x + y

3x - 2x + y + 1 = 2x - 2x + y

x + y + 1 = y

Step 3 - Subtract y from both sides:

x + y + 1 = y

x + y - y + 1 = y - y

x + 1 = 0

x = -1

Step 4 - Plug known variable back into the first equation:

3x + y = 4

3(-1) + y = 4

-3 + y = 4

Step 5 - Add 3 to both sides to isolate the y:

-3 + y = 4

-3 + 3 + y = 4 + 3

y = 7

Meaning the two coordinates  are:

If you meet all the criteria for an independent t-test but do not satisfy the assumption of normality, you should technically do a non-parametric test instead of an independent t-test.

So, the correct answer is D.

Non-parametric tests do not require the data to be normally distributed, unlike parametric tests such as t-tests. Non-parametric tests include the Mann-Whitney U test, Wilcoxon rank-sum test, and Kruskal-Wallis test.

These tests are based on ranks rather than the actual values of the data and are generally less powerful than parametric tests, meaning that they may require larger sample sizes to achieve the same level of statistical significance.

It is important to choose the appropriate statistical test for your data to ensure accurate results and conclusions. Simply redoing the experiment or ignoring the violation of the normality assumption is not a valid solution.
