Step-by-step explanation:

wand and gone have similar sounds so these rhyme

land and hands rhyme

The value of n can be determined by finding the number of visible arcs in the pattern, which is 30 in this case.

To determine the value of n, we need to find the relationship between the total length of visible areas and the number of circles (n).

In the given pattern, each circle contributes to the visible area twice: once as its circumference and once as the overlapping part with the adjacent circles. Since the circumference of each circle is 1 unit, the visible area contributed by each circle is 2 units.

Therefore, the total length of visible areas can be expressed as 2n. Given that the total length is 60 units, we can set up the equation:

2n = 60

Solving this equation, we find:

n = 60/2 = 30

Thus, the value of n is 30.

The simplified form of the expression (8.35 × 10⁻¹²) ÷ (3.22 × 10⁻⁵) is 2.59 × 10⁻⁷.

Given the expression in the question;

(8.35 × 10⁻¹²) ÷ (3.22 × 10⁻⁵)

To evaluate the expression (8.35 × 10⁻¹²) ÷ (3.22 × 10⁻⁵), we can use the following steps:

So, starting with step 1:

(8.35 ÷ 3.22) = 2.592357

Using exponent rule

(10⁻¹² ÷ 10⁻⁵) = 10⁻¹² ⁻ ⁻⁵ = 10⁻¹² ⁺ ⁵ = 10⁻⁷

Moving on to step 2:

2.592357 × 10⁻⁷ = 2.592357 × 0.0000001 = 0.0000002592357

Finally, in step 3, we can rewrite this answer in standard form to 3 significant figures:

0.0000002592357 = 2.59 × 10⁻⁷

Therefore, the simplified form is 2.59 × 10⁻⁷.

To solve this question, we find the sample mean, sample standard deviation, sample size, the number of degrees of freedom, the confidence interval and the required sample size. For each step, the procedures are explained and we find what is asked.

Doing this, we find that the sample mean is 347.3, the sample standard deviation is 467.4, the sample size is 10, the number of degrees of freedom is 9, the t-value for a 95% confidence interval is t = 2.2226, the margin of error for a 95% confidence interval for this sample is 328.5, the 95% CI is $18.8 < µ < $675.8 and the sample size needed in order to obtain a margin of error of no more than 100 is 94.

--------------------------------------

The sample mean is

Sum of all values divided by the number of values, thus:

\(\overline{x} = \frac{102 + 69 + 280 + 180 + 33 + 89 + 1643 + 205 + 177 + 695}{10} = 347.3\)

The sample mean is 347.3.

--------------------------------------

The sample standard deviation is

Square root of the sum of the difference squared between each value and the mean, divided by one less than the sample size. So

\(s = \sqrt{\frac{(102-347.3)^2 + (69-347.3)^2 + (280-347.3)^2 + (180-347.3)^2 + (33-347.3)^2 + (89-347.3)^2 + \cdots}{9}} = 467.4\)

The sample standard deviation is 467.4.

--------------------------------------

The sample size is

10 observations, thus the sample size is 10.

--------------------------------------

The degree of freedom for the Studentized version of the sample mean is

One less than the sample size, so 10 - 1 = 9.

The number of degrees of freedom is 9.

--------------------------------------

The point estimate for the mean of ALL US Overseas Loans and Grants is

The sample mean, which is 347.3.

The point estimate is 347.3.

--------------------------------------

The t-value for a 95% confidence interval is t

The t-value is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of \(1 - \frac{1 - 0.95}{2} = 0.975\). So we have T = 2.2226.

The t-value for a 95% confidence interval is t = 2.2226.

--------------------------------------

The Margin of error for a 95% confidence interval for this sample is

\(M = t\frac{s}{\sqrt{n}}\)

In which s is the standard deviation of the sample and n is the size of the sample.

For this question, \(s = 467.4, n = 10\), and thus:

\(M = 2.2226\frac{467.4}{\sqrt{10}}\)

\(M = 328.5\)

The margin of error for a 95% confidence interval for this sample is 328.5.

--------------------------------------

The 95 % confidence interval estimate of the mean of ALL US Overseas Loans and Grants is

The lower end of the interval is the sample mean subtracted by M. So it is 347.3 - 328.5 = 18.8

The upper end of the interval is the sample mean added to M. So it is 347.3 + 328.5 = 675.8

The 95 % confidence interval estimate of the mean of ALL US Overseas Loans and Grants is:

$18.8 < µ < $675.8.

--------------------------------------

The sample size is needed in order to obtain a margin of error of no more than 100 is

Here, we have to consider the sample standard deviation as the population standard deviation, and use the z-distribution. So

We have to find our  level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\(\alpha = \frac{1 - 0.95}{2} = 0.025\)

Now, we have to find z in the Z-table as such z has a p-value of .

That is z with a p-value of , so Z = 1.96.

Now, find the margin of error M as such

\(M = z\frac{\sigma}{\sqrt{n}}\)

In which \(\sigma\) is the standard deviation of the population and n is the size of the sample.

In this question, \(\sigma = 467.4\)

We have to find n for which M = 100. So

\(M = z\frac{\sigma}{\sqrt{n}}\)

\(100 = 1.96\frac{467.4}{\sqrt{n}}\)

\(100\sqrt{n} = 1.96*467.4\)

Dividing both sides by 100:

\(\sqrt{n} = 1.96*4.674\)

\((\sqrt{n})^2 = (1.96*4.674)^2\)

\(n = 83.92\)

The sample size needed in order to obtain a margin of error of no more than 100 is 94.

To show that the angle bisector of an equilateral triangle is perpendicular to the base​, we can assume an equilateral triangle with sides ABC. Next, we can get an angle bisector in the middle represented by BD which becomes perpendicular to the base BC.  

After getting the angle bisector, we would see that the line segment BD, divides angle BAC into two equal angles, each measuring 30 degrees. Now, we can draw a perpendicular line from point D to the base BC.

We could also draw a line E, which is the perpendicular line that intersects the base BC. We want to show that BD is perpendicular to BC, which means we need to show that angle BDE is a right angle.

Since the sum of angles BDA and ADE is 90 degrees (they form a right angle), and the sum of angles BAD, ABD, and BDA is 180 degrees, it follows that angle BDE must be a right angle.

Therefore, we have shown that the angle bisector of an equilateral triangle is perpendicular to the base.

The given sequence does not follow a simple arithmetic or geometric pattern, making it challenging to determine an explicit rule based on the given terms.

To identify the type of sequence and write the explicit rule, we need to examine the pattern of the given sequence: -39, -45, 51, 57, ...

By observing the differences between consecutive terms, we can determine if it follows an arithmetic or geometric pattern.

Arithmetic sequences have a common difference between each term, meaning that by adding (or subtracting) the same value repeatedly, we can generate the sequence. Geometric sequences, on the other hand, have a common ratio between each term, meaning that by multiplying (or dividing) by the same value repeatedly, we can generate the sequence.

Let's calculate the differences between consecutive terms:

-45 - (-39) = -6

51 - (-45) = 96

57 - 51 = 6

From the differences, we can see that the sequence is not arithmetic since the differences are not constant. However, the differences alternate between -6 and 6, indicating a possible geometric pattern.

Let's calculate the ratios between consecutive terms:

-45 / (-39) ≈ 1.1538

51 / (-45) ≈ -1.1333

57 / 51 ≈ 1.1176

The ratios are not constant, indicating that the sequence is neither geometric nor arithmetic.

Therefore, the given sequence does not follow a simple arithmetic or geometric pattern, and it is difficult to determine the explicit rule based on the given terms. It is possible that the sequence follows a more complex pattern or rule that is not apparent from the given terms.
