a tree has degree sequence (6,6,6,6,4,...), where the rest of the vertex degrees are either 2 or 1. find the number of vertices with degree 1.
Answers
The tree has 11 vertices with degree 1.
To find the number of vertices with degree 1 in a tree with degree sequence (6,6,6,6,4,...), we can use the Handshaking Lemma. This lemma states that the sum of all vertex degrees in a graph is twice the number of edges. In a tree, the number of edges is one less than the number of vertices, so we can write:
6+6+6+6+4+...+2+2+1+1 = 2n-1
where n is the number of vertices. Simplifying this equation gives:
n = (6+6+6+6+4+...+2+2+1+1+1)/2 + 1
The term inside the parentheses is the sum of all vertex degrees, which we know from the degree sequence. Plugging in the values and simplifying, we get:
n = 18
So the tree has 18 vertices. Since we know that the rest of the vertex degrees are either 2 or 1, we can subtract the six vertices with degree 6 and the one vertex with degree 4 to get:
18 - 6 - 1 = 11

1. A random sample of 400 married couples was selected from a large population of married couples. There were 20 couples in which the wife was taller than her husband, and there were 380 couples in which the wife was shorter that her husband. Find a 95 percent confidence interval for the proportion of married couples in the population for which the wife is taller than her husband. Interpret your interval in the context of this question.
Answers
Answer:
\(CI = (0.028636,0.071364)\)
I am 95% confident that the true proportion of couples where the wife is taller than her husband is captured in the interval (.028, .071)
Step-by-step explanation:
Given
\(n = 400\)
\(x = 20\) --- taller wife
\(y = 380\) --- shorter wife
Required
Determine the 95% confidence interval of taller wives
First, calculate the proportion of taller wives
\(\hat p = \frac{x}{n}\)
\(\hat p = \frac{20}{400}\)
\(\hat p = 0.05\)
The z value for 95% confidence interval is:
\(z = 1.96\)
The confidence interval is calculated as:
\(CI = \hat p \± z \sqrt{\frac{\hat p (1 - \hat p)}{n}}\)
\(CI = 0.05 \± 1.96* \sqrt{\frac{0.05 (1 - 0.05)}{400}}\)
\(CI = 0.05 \± 1.96 * \sqrt{\frac{0.0475}{400}}\)
\(CI = 0.05 \± 1.96 * \sqrt{0.00011875}\)
\(CI = 0.05 \± 1.96 * 0.01090\)
\(CI = 0.05 \± 0.021364\)
This gives:
\(CI = (0.05 - 0.021364,0.05 + 0.021364)\)
\(CI = (0.028636,0.071364)\)

Suppose there are two producers in a market with the following supply functions. Supply 1: P=6+0.7Q Supply 2:P=16+0.6Q When the price is [Answer], the total quantity supplied is 250. (In decimal numbers, with two decimal places, please.) Answer:
Answers
The price at which the total quantity supplied is 250 is $11.58.
In order to find the price at which the total quantity supplied is 250, we need to equate the total quantity supplied by both producers (Supply 1 and Supply 2) and solve for the price.
Supply 1: P = 6 + 0.7Q
Supply 2: P = 16 + 0.6Q
To find the equilibrium price, we set the total quantity supplied equal to 250:
0.7Q + 0.6Q = 250
1.3Q = 250
Q = 250 / 1.3 ≈ 192.31
Now that we have the quantity, we can substitute it back into either supply function to find the price. Let's use Supply 1:
P = 6 + 0.7Q
P = 6 + 0.7 * 192.31
P ≈ 6 + 134.62
P ≈ 140.62
Therefore, the price at which the total quantity supplied is 250 is approximately $11.58.

Write an equation that passes through (4,-3) and is perpendicular to y=1/2x-3
Answers
Given:
The equation of a line is y = (1/2)x-3.
Another line passes perpendicular to the first line through the point,
\((x_1,y_1)=(4,-3)\)The objective is to find the equation of the second line.
Explanation:
In general, the product of the slope of perpendicular lines will be -1.
Consider the slope of the first-line as m1 and the slope of the second-line is m2.
To find m1:
From the given equation, the slope of the first line will be,
\(m_1=\frac{1}{2}\)To find m2:
Then, the slope of the second line can be calculated as,
\(\begin{gathered} m_1\times m_2=-1 \\ m_2=-\frac{1}{m_1} \\ m_2=-\frac{1}{\frac{1}{2}} \\ m_2=-2 \end{gathered}\)To find the equation of the second line:
The equation of a line using the slope and the point can be calculated as,
\(y-y_1=m_2(x-x_1)\)On plugging the obtained values in the above equation.
\(\begin{gathered} y-(-3)=-2(x-4) \\ y+3=-2x+8 \\ y=-2x+8-3 \\ y=-2x+5 \end{gathered}\)Hence, the equation of the line is y=-2x+5.

(Round to three decimal places as needed.) c) How would the confidence interval change if the confidence level had been 99% instead of 98% ? The new confidence interval would be The new confidence interval would be (Round to three decimal places as needed.)
Answers
a) If the confidence level had been 90% instead of 98%, the new confidence interval would be (0.325, 0.475).
b) If the sample size had been 255 instead of 170, the new confidence interval would be (0.292, 0.508).
c) If the confidence level had been 99% instead of 98%, the new confidence interval would be (0.304, 0.496).
a) First, we find the mean of the original confidence interval:
Mean = (Lower Limit + Upper Limit) / 2 = (0.313 + 0.487) / 2 = 0.4
Margin of Error = (Upper Limit - Mean) = (0.487 - 0.4) / 2 = 0.0435
New Margin of Error = Margin of Error * \((Z_{90} / Z_{98})\)
where \(Z_{90}\) is the critical value for a 90% confidence level, and \(Z_{98}\) is the critical value for a 98% confidence level.
From the standard normal distribution table, we find:
\(Z_{90}\) ≈ 1.645
\(Z_{98}\) ≈ 2.326
New Margin of Error = 0.0435 * (1.645 / 2.326) ≈ 0.0306
Finally, we construct the new confidence interval using the adjusted margin of error:
New Confidence Interval = (Mean - New Margin of Error, Mean + New Margin of Error)
= (0.4 - 0.0306, 0.4 + 0.0306)
≈ (0.3694, 0.4306)
Therefore, the new confidence interval at a 90% confidence level would be approximately (0.369, 0.431) when rounded to three decimal places.
b) Standard Error = \(\sqrt{(p_{hat} * (1 - p_{hat})) / n}\)
where \(p_{hat}\) is the sample proportion and n is the sample size.
Given that the sample size increases to 255 while the sample proportion remains the same, the new sample proportion is:
\(p_{hat}\) = 68 / 255 ≈ 0.267
Standard Error = sqrt((0.267 * (1 - 0.267)) / 255) ≈ 0.028
For a 98% confidence level, the critical value is \(Z_{98}\) ≈ 2.326.
New Margin of Error = \(Z_{98}\) * Standard Error = 2.326 * 0.028 ≈ 0.065
New Confidence Interval = (\(p_{hat}\) - New Margin of Error, \(p_{hat}\) + New Margin of Error)
= (0.267 - 0.065, 0.267 + 0.065)
≈ (0.202, 0.332)
Therefore, the new confidence interval with a sample size of 255 would be approximately (0.202, 0.332) when rounded to three decimal places.
c) From the standard normal distribution table, we find:
\(Z_{99}\) ≈ 2.576
New Margin of Error = Margin of Error * (\(Z_{99}\) / \(Z_{98}\)) = 0.0435 * (2.576 / 2.326) ≈ 0.0482
New Confidence Interval = (Mean - New Margin of Error, Mean + New Margin of Error)
= (0.4 - 0.0482, 0.4 + 0.0482)
≈ (0.3518, 0.4482)
Therefore, the new confidence interval at a 99% confidence level would be approximately (0.352, 0.448) when rounded to three decimal places.

If the length of a rectangle is decreased by 4 cm and the width is increased by 5 cm, the result will be a square. The area of the square will be 40 cm greater than the area of the rectangle. Find the area of the rectangle.
Answers
The area of the rectangle is found to be 20 - 2·√(10) sq. units.
Explain about the area of rectangle?The territory a rectangle occupies inside its 4 sides or limits is known as its area. In fact, the length and width of the rectangle multiplied jointly gives the area of the rectangle.Let x be the length of the rectangle.
Let y be the width of rectangle.
Then, length is reduced by 4 and with is increased by 5.
x - 4 = y + 5 , (becomes square) ....eq 1
Area of square = 40 cm²
Then,
(x - 4) × (y + 5) = 40 cm²
From eq 1
(y + 5) × (y + 5) = 40 cm²
y² + 10y + 25 = 40
y² + 10y + 25 - 40 = 0
y² + 10y - 15 = 0
Solving equation by quadratic formula:
y = -5 + 2·√(10)
Then, for x:
x - 4 = 5 + -5 + 2·√(10) = 2·√(10)
x = 4 + 2·√(10)
Now,
Area of the rectangle, A = x × y
Put the values:
A = (-5 + 2·√(10)) × (4 + 2·√(10))
A = 20 - 2·√(10)
Thus, the area of the rectangle is found to be 20 - 2·√(10) sq. units.

Answers
The equation can be solved by adding 3 to both sides of the equation.
Solve the equation t − 3 = 17 for t?To solve the equation t − 3 = 17, we need to add 3 to both sides of the equation. Doing so, we get t = 17 + 3 = 20. Therefore, the value of t is 20.In this case, the variable is t. The equation t - 3 = 17 has 3 subtracted from t on the left side, so to isolate t, we must add 3 to both sides to make the equation equal. Once we do this, we are left with t = 20.The equation t − 3 = 17 is an equation with a single variable, t.The equation t - 3 = 17 is a simple algebraic equation that can be solved by performing the inverse operation of subtraction. To solve this equation, we must first add 3 to both sides of the equation.Therefore, the solution to the equation t - 3 = 17 is t = 20.The equation can be solved by adding 3 to both sides of the equation. When 3 is added to the left side of the equation, it cancels out the -3, leaving just t. When 3 is added to the right side of the equation, it increases the value of the right side from 17 to 20. Therefore, the equation t − 3 = 17 can be solved by adding 3 to both sides, which results in the equation t = 20.This means that the value of t is 20.To learn more about the value of the unknown variable refer to:

sin(x)=cos(30)
what's the value of X
Answers
To find the value of x when sin(x) is equal to cos(30°), we can use the trigonometric identity:
sin(x) = cos(90° - x)
Using this identity, we can rewrite the equation as:
cos(90° - x) = cos(30°)
For two angles to be equal, their cosine values must also be equal. Therefore, we have:
90° - x = 30°
Subtracting 30° from both sides, we get
90° - 30° = x
To find the value of x, we need to determine the angle whose sine is equal to √3/2. This angle is 60 degrees, or π/3 radians. This can be verified by looking at the unit circle or by using inverse trigonometric functions.
Simplifying, we have:
60° = x
Therefore, the value of x that satisfies the equation sin(x) = cos(30°) is x = 60°.
Note that trigonometric functions are periodic, meaning there are infinitely many angles that satisfy a given equation.
In this case, the equation sin(x) = cos(30°) holds true for any angle x that is equivalent to 60° modulo 360°.
So, we could also write the solution as x = 60° + 360°n, where n is an integer representing the number of complete revolutions around the unit circle.
