Yes, the cost of t* you would use for a 90% self-belief interval with a pattern length of 30 is 1.645.

To compute a 90% self-belief c programming language for the mean of a population with an unknown population well-known deviation, you would use the t-distribution. The vital fee, denoted as t*, is primarily based on the preferred self-assurance stage and the degrees of freedom, that's the same as the sample size minus 1 (n - 1).

In this situation, the pattern size is 30, so the tiers of freedom are 30 - 1 = 29. To locate an appropriate fee of t* for a 90% confidence stage, you could talk to the t-distribution table or use a statistical software program.

For a 90% confidence level and 29 tiers of freedom, the price of t* is approximately 1.645. This approach that 90% of the t-distribution falls inside ±1.645 trendy deviations from the suggestion.

Using this cost of t*, you can compute the confidence c language by taking the sample suggested and including/subtracting the margin of mistakes, which is fabricated from t* and the same old errors of the mean.

Remember that the t* cost may additionally vary slightly depending on the level of precision required and the precise table or software used, however, 1.645 is a normally used approximation for a 90% self-assurance c program language period with a sample size of 30.

(a) A graph on 16 vertices in which every vertex has degree 4 does not exist.

(b) A graph on 15 vertices in which 8 vertices have degree 6 and 7 vertices have degree 5 does not exist.

(c) A graph on 14 vertices in which every vertex has degree 3 and the shortest cycle has length 6 does not exist.

(d) A graph on 11 vertices in which every vertex has degree at least 6 and there are no cycles of length 3 does not exist.

In graph theory, the degree of a vertex refers to the number of edges incident to that vertex. To determine whether a graph with specific properties exists or not, we need to consider the constraints imposed by the given conditions.

(a) For a graph with 16 vertices, where every vertex has a degree of 4, we can calculate the sum of the degrees as 16 * 4 = 64. However, since each edge contributes two degrees (one for each of its endpoints), the sum of degrees in any graph is always twice the number of edges. Therefore, the total number of edges in the graph would be 64/2 = 32. However, each edge connects two distinct vertices, so the total number of distinct pairs of vertices is (16 choose 2) = 120. But, 32 is less than 120, which means it is impossible to have a graph with the given conditions.

(b) Similarly, for a graph with 15 vertices, where 8 vertices have a degree of 6 and 7 vertices have a degree of 5, the sum of degrees is (8 * 6) + (7 * 5) = 101. As before, the number of edges is half the sum of degrees. Therefore, we would need 101/2 = 50.5 edges, which is not possible since the number of edges must be an integer.

(c) In a graph with 14 vertices, where each vertex has a degree of 3 and the shortest cycle has a length of 6, we observe that the shortest cycle has an even number of vertices. However, in a graph with an odd number of vertices, each vertex must have an odd degree in order for a cycle to exist. Since 3 is an odd number, the sum of degrees in a graph with 14 vertices would be even (14 * 3 = 42), which means it is impossible to have a cycle of length 6.

(d) For a graph with 11 vertices, where each vertex has a degree of at least 6 and no cycles of length 3, let's assume such a graph exists. In any graph, the sum of degrees is twice the number of edges. So, the sum of degrees in this case would be at least (11 * 6) = 66. But since the number of edges must be an integer, the sum of degrees must be even. However, a sum of degrees of 66 is odd, which contradicts the condition. Therefore, no such graph can exist.

Step-by-step explanation:

Nominal measurement is used to assign a category or label, Ordinal is used to rank objects in a specific order, Interval is used to indicate distance between two points on a scale and Ratio is used to indicate proportion of one quantity to another.

Measurements are a way of quantifying certain characteristics of an object or phenomenon. There are different types of measurements, each with their own characteristics and uses. The four main types of measurements are nominal, ordinal, interval, and ratio.

Nominal measurements are used to assign a category or label to an object or phenomenon. For example, the colors of a rainbow (red, orange, yellow, green, blue, indigo, and violet) are a nominal measurement because they are simply labels, and there is no inherent order or difference between them.

Ordinal measurements are used to rank objects or phenomena in a specific order. For example, the ranks of a military organization (private, corporal, sergeant, captain, etc.) are an ordinal measurement because they indicate a specific order, but there may not be a consistent difference between the ranks.

Interval measurements are used to indicate the distance between two points on a scale. For example, temperature measured in degrees Celsius is an interval measurement because it tells us the difference in temperature between two points, such as 20 degrees Celsius and 30 degrees Celsius, but there is no true zero point on the scale (absolute zero is not 0 degrees Celsius).

Ratio measurements are used to indicate the proportion of one quantity to another. For example, weight measured in kilograms is a ratio measurement because it tells us the proportion of one weight to another, such as one person weighing 50 kilograms and another person weighing 100 kilograms, and there is a true zero point on the scale (0 kilograms).

Answer:

57 units^2

Step-by-step explanation:

First find the area of the triangle on the left

ABC

It has a base AC which is  9 units and a height of 3 units

A = 1/2 bh = 1/2 ( 9) *3 = 27/2 = 13.5

Then find the area of the triangle on the right

DE

It has a base AC which is  6 units and a height of 1 units

A = 1/2 bh = 1/2 ( 6) *1  = 3

Then find the area of the triangle on the top

It has a base AC which is  3 units and a height of 3 units

A = 1/2 bh = 1/2 ( 3) *3  = 9/2 = 4.5

Then find the area of the rectangular region

A = lw = 6*6 = 36

Add them together

13.5+3+4.5+36 =57 units^2

Answer:

Total Area = 57 sq. units

Step-by-step explanation:

will make it simple and short

Total Area = A1 + A2 + A3

A1 = (7 + 6) * 6/2 = 39 sq. units  (area of a trapezoid)

A2 = 1/2 (9 * 3) = 13.5 sq. units (area of a triangle)

A3 = 1/2 (3 * 3) = 4.5 sq. units  (area of a triangle)

Total Area = 39 + 13.5 + 4.5 = 57 sq. units

Step-by-step explanation:

To determine the height of a tree using geometric means, we can set up a proportion based on similar triangles.

Let's assume "h" represents the height of the tree.

We have the following information: Distance from the tree: 8 ft

Height to your eyes: 4 ft

We can set up the proportion: Your height to distance = Tree height to distance

4 ft / 8 ft = h / (8 ft + h)

To solve for "h," we can cross-multiply and then solve the resulting equation:

4 ft * (8 ft + h) = 8 ft * h

4(8 + h) = 8h

32 + 4h = 8h

32 = 4h

Divide both sides of the equation by 4:

8 = h

Therefore, the height of the tree is 8 feet.

The intersection of sets a and b is {g, h}, while the intersection of sets b and c is {a, h}. The union of all three sets is {a, b, e, g, h, i, j}.

In set theory, the intersection of two or more sets refers to the elements that are common to all the sets. In this case, we can see that the intersection of sets a and b is {g, h}, meaning that these two sets share those two elements. Similarly, the intersection of sets b and c is {a, h}, indicating that those two sets share those two elements.

The union of two or more sets refers to the set of all elements that are in any of the sets being combined. In this case, the union of sets a, b, and c is {a, b, e, g, h, i, j}, meaning that all elements from those three sets are included in the combined set.

We will find the area of the putting green by dividing it into 3 sections as shown in the following figure:

Area (1) is the area of a rectangle with dimensions 4.5 and 8 feets

so, the area (1) = 4.5 x 8 = 36 feet²

Area (2) is the area of a square with a side length of 4.5 feet

So, the area (2) = 4.5 x 4.5 = 20.25 feet²

Area (3) is the area of the sector of a circle with a radius = 4.5 feet

The sector represents the quarter of the circle

so, Area (3) =

So, the total area is the sum of the three areas:

The p-value is .11 and the significance level is .05, then we fail to reject the null hypothesis.

The p-value represents the probability of obtaining the observed results, or results more extreme, assuming the null hypothesis is true. In this case, the p-value is greater than the significance level, which means that the observed results are not significant enough to reject the null hypothesis.
With a p-value of .11 and a significance level of .05, we can conclude that there is not enough evidence to reject the null hypothesis.
When comparing the p-value to the significance level (0.05), if the p-value is less than or equal to the significance level, you would reject the null hypothesis, indicating that there is a significant effect or difference.

If the p-value is greater than the significance level, you would fail to reject the null hypothesis, meaning that you cannot conclude that there is a significant effect or difference.

Hence, the p-value (0.11) is greater than the significance level (0.05), you fail to reject the null hypothesis, which means you cannot conclude that there is a significant effect or difference.

The basic unit of mass of the ball in the metric system is the gram.

The base units of length (distance), capacity (volume), and weight (mass) in the metric system are the meter, liter, and gram, respectively. We utilize units that are derived from metric units to measure smaller or greater quantities.

Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of an object's gravitational pull to other bodies is also influenced by its mass.

Therefore, the basic unit of mass of the ball in the metric system is the gram.

By the radius-tangent theorem, the radius is equal to 39/10 units.

In Euclidean geometry, Pythagorean's theorem is given by this mathematical expression:

a² + b² = c²

Where:

a, b, and c represents the side lengths of a right-angled triangle.

Since CB is tangent to OA at point C and line segment CB is perpendicular to line segment AC by the radius-tangent theorem, we would determine the radius by applying Pythagorean's theorem as follows;

r^2 + 8^2 = (r + 5)^2

r^2 + 64 = r^2 + 10r + 25

r^2 - r^2 = -10r + 64 - 25

The new monthly payment is = 11.10 x 50 = 555

The percent increase in his monthly payment is 1.947%

Given,

Sandra Williams bought a home with a 10.25% adjustable rate mortgage for 25 years. She paid $9.27 monthly per thousand on his original loan

According to the question:

So, per thousand value of $65000 is 50000/1000 =50

Now, the old monthly payment was =  9.27 x 50 = 463.5

She decides to renew and will now pay $11.10 monthly per thousand on his loan.

So, the new monthly payment is = 11.10 x 50 = 555

The percent increase in his monthly payment is= 11.10 /9.27 - 1 x 100

19.7411 % and to nearest tenth it is 1.947%

Hence, the old monthly payment was =  9.27 x 50 = 463.5
