Each small square on the quilt is the same size. The length of a side of a small square is 3 inches. What is the area of the ​quilt? Explain.

130/200 = .65 or 65%

Answer: 65%

Step-by-step explanation:

The power of the test is low and not sufficient to detect a significant difference between the two treatments with the given sample size of 35.

To calculate the expected power of the test, we need to consider the survival rates, the significance level, and the sample size. Let's follow these steps:

Determine the proportions
Old treatment survival rate (p1) = 0.75
New treatment survival rate (p2) = 0.85

Determine the significance level
Two-sided significant difference level (α) = 0.05

Calculate the pooled proportion
Pooled proportion (p) = (p1 + p2) / 2 = (0.75 + 0.85) / 2 = 0.80

Calculate the standard error
Standard error (SE) = √(p × (1 - p) × (1/n1 + 1/n2)) = √(0.80 × (1 - 0.80) × (1/35 + 1/35)) ≈ 0.065

Calculate the test statistic (z)
z = (p2 - p1) / SE = (0.85 - 0.75) / 0.065 ≈ 1.54

Find the critical value for the two-sided significant difference at the 5% level
z_critical = 1.96 (from a standard normal distribution table)

Calculate the power of the test
In this case, since the test statistic is smaller than the critical value (1.54 < 1.96), we cannot reject the null hypothesis at the 5% significance level.

The P-value, or observed significance level, is a statistical measure that indicates the likelihood of obtaining a result as extreme or more extreme than the one observed, assuming that the null hypothesis is true.

It represents the probability of observing a result that is as or more extreme than the one found, given that the null hypothesis is correct. A low P-value indicates that the observed results are unlikely to occur by chance alone, and therefore suggests that the null hypothesis should be rejected in favor of the alternative hypothesis. Generally, a P-value less than 0.05 is considered significant, meaning that there is less than a 5% chance of obtaining the observed result by chance if the null hypothesis is true.

The problem requires finding the values of the nodes on the right side of a binary tree, ordered from top to bottom. We can solve this problem by performing a level-order traversal of the binary tree and keeping track of the rightmost node at each level. We only add the rightmost node to the result list for each level.

To solve this problem, we can perform a level-order traversal of the binary tree and keep track of the rightmost node at each level. We can use a queue to traverse the tree level by level, starting with the root node. For each level, we only add the rightmost node to the result.

Here's the Python code to implement this approach:

```
from collections import deque

def rightSideView(root):
   if not root:
       return []
   
   result = []
   queue = deque([root])
   
   while queue:
       level_size = len(queue)
       
       for i in range(level_size):
           node = queue.popleft()
           
           # Only add the rightmost node to the result
           if i == level_size - 1:
               result.append(node.val)
           
           # Add the child nodes to the queue
           if node.left:
               queue.append(node.left)
           if node.right:
               queue.append(node.right)
   
   return result
```

We first handle the case where the root is None, in which case we return an empty list. We then initialize an empty list `result` to store the values of the rightmost nodes and a queue `queue` to perform the level-order traversal.

We begin by adding the root node to the queue. We then enter a loop that continues until the queue is empty. In each iteration of the loop, we first get the number of nodes in the current level by taking the length of the queue. We then iterate through the nodes in the current level and remove them from the queue using `popleft()`.

For each node, we check if it is the rightmost node in the current level (i.e., its index is equal to the level size minus one). If it is, we add its value to the result list. We then add the child nodes of the current node to the queue if they exist.

Finally, we return the result list containing the values of the rightmost nodes in the binary tree.

For example, for the binary tree given in the prompt, the function `rightSideView(root)` will return [1, 3, 4].

Always remember to set your calculator to **degrees** when working with Law of Sines & Cosines.

When working with Law of Sines & Cosines, it's important to remember to set your calculator to "degree" mode if you're working with angles measured in degrees.

This is because the equations for Law of Sines & Cosines use trigonometric functions that are dependent on the units used for the angles.

If you use the wrong mode on your calculator, your answers will be incorrect.

The Law of Sines and the Law of Cosines are two important formulas in trigonometry that help us solve triangles.

The Law of Sines, also known as the Sine Rule, is used to find the length of a side or measure of an angle in a triangle when we know the length of two sides and the angle between them or the length of one side and the measures of the angles opposite to it.

The formula for the Law of Sines is:

sin A / a = sin B / b = sin C / c

where A, B, and C are the angles of the triangle, and a, b, and c are the sides opposite to those angles, respectively.

The Law of Cosines, also known as the Cosine Rule, is used to find the length of a side or measure of an angle in a triangle when we know the lengths of the other two sides and the angle between them.

The formula for the Law of Cosines is:

[tex]c^2 = a^2 + b^2 - 2ab cos(C)[/tex]

where c is the side opposite to the angle C, and a and b are the other two sides of the triangle.

This formula can be rearranged to solve for any of the three sides or any of the three angles of the triangle.

There are seven months in the Gregorian calendar that have thirty-one days: January, March, May, July, August, October, and December.

This pattern of months with 31 days followed by months with fewer days repeats throughout the year.

This pattern was established by the Roman calendar, which had ten months totaling 304 days in a year.

The months of January and February were later added by King Numa Pompilius to align the calendar with the lunar year.

The months of January and February initially had 29 and 28 days respectively, but in 45 BC, Julius Caesar added one day to January and one day to August, which was originally a 30-day month, to make them both 31-day months.

In the Gregorian calendar, which is the most widely used calendar in the world, January, March, May, July, August, October, and December all have 31 days.

The remaining five months have fewer days, with February having 28 days most of the time, and 29 days in a leap year.

Knowing the number of days in each month is important for various reasons, such as planning events, scheduling appointments, and calculating pay periods.

There are several mnemonics used to remember the number of days in each month, such as "30 days hath September, April, June, and November, all the rest have 31, except February, with 28 days clear, and 29 in each leap year."

The insurance company's expected profit from insuring this person's coin collection is $260.

The insurance company's expected profit can be calculated using the terms: coin collection value, annual premium, and probability of theft. In this case, the coin collection is worth $20,000, the annual premium is $300, and the probability of theft is 0.002.

To find the expected profit, we first need to determine the expected loss, which is the product of the coin collection value and the probability of theft: $20,000 x 0.002 = $40. This means that, on average, the company expects to pay out $40 per year for potential theft claims.

Next, we compare the expected loss to the annual premium. The insurance company collects $300 from the policyholder each year as the annual premium. To find the expected profit, we subtract the expected loss from the annual premium: $300 - $40 = $260.

Therefore, the insurance company's expected profit for insuring the coin collection is $260 per year. This calculation assumes that the probability of theft remains constant and does not account for other factors, such as administrative expenses or changes in the collection's value.

The probability of obtaining between 9 and 14 heads, exclusive, in 45 tosses of a coin with probability of heads = 0.25 is approximately 0.6516.

The number of heads obtained in 45 tosses of a coin with probability of heads = 0.25 follows a binomial distribution with parameters n = 45 and p = 0.25.

Let X be the number of heads obtained in 45 tosses. We need to find P(9 < X < 14).

Using the cumulative probability function for a binomial distribution, we can write:

P(9 < X < 14) = P(X < 14) - P(X < 9)

= F(13; 45, 0.25) - F(8; 45, 0.25)

where F(x; n, p) is the cumulative probability function for a binomial distribution with parameters n and p, which gives the probability of obtaining up to x successes in n independent trials with probability of success p.

Using a binomial probability table or a calculator, we can find:

F(13; 45, 0.25) = 0.6961

F(8; 45, 0.25) = 0.0445

Therefore,

P(9 < X < 14) = F(13; 45, 0.25) - F(8; 45, 0.25)

 We integrate the surface area of each shell from 0 to 13, then multiply by the thickness of ech shell (d x), and finally add up all the shells.

The radius of each shell is given by the distance from the axis of rotation (y =14) to the function y = x, which is r  = 14 - x. The height of each shell is given by the function   y = 13 - x.

Therefore, the volume of the solid is stated as

The area of metal needed to make the tool is r² times the sum of 1/2π and the square root of 3.

To determine the area of metal needed to make the tool, we need to find the areas of the semicircle and the isosceles triangle and then add them together.

The area of a semicircle with radius r is:

A(semi-circle) = 1/2πr²

Since the tool consists of a semicircle, we can use the diameter of the semicircle to represent the width of the isosceles triangle.

Let the height of the isosceles triangle be h and the base be b.

Since the triangle is isosceles, we can divide it in half and treat it as a right triangle.

Using the Pythagorean :

h² + (b/2)² = r²

Since the diameter of the semicircle is the same as the base of the isosceles triangle, we have:

b = 2r

Substituting this into the equation above, we get:

h² + r² = 4r²

h² = 3r²

h = √(3)r

The area of an isosceles triangle with base b and height h is:

A(triangle) = 1/2bh

Substituting b = 2r and h = √(3)r, we get:

A(triangle) = 1/2(2r)(√(3)r)

A(triangle) = √(3)r²

Adding the area of the semicircle and the isosceles triangle, we get:

A(tool) = A(semi-circle) + A(triangle)

One of the rectangles has a width of 8ft and a height of 5ft + 4ft + 4ft = 13ft, then its area is:

A = 8ft*13ft = 103 ft²

The second rectangle, the one at the rigth side, has a width of 7ft and a height of 5ft, thus the area is:

A' = 5ft*7ft = 35ft²

The middle rectangle has a heigth of 5ft + 4ft = 9ft and a width of:

W = 18.5ft - 8ft - 7ft = 3.5ft

Then the area is:

A'' = 3.5ft*9ft = 31.5 ft²

The total area is:

area = A + A' + A'' = 103 ft² + 35ft² +  31.5 ft²

area = 169.5 ft²
