1. Two lines that do not lie in the same plane and are parallel:

- Line 1: x = 2y + 3z

- Line 2: x = 2y + 3z + 5

In this case, both lines have the same direction vector, which is [2, 1, 0], but they do not lie in the same plane.

2. Two planes that have no point in common and are skew lines:

- Plane 1: x + 2y - z = 4

- Plane 2: 2x - 3y + z = 6

These two planes are skew because they do not intersect and have no common points.

3. Two lines that are in the same plane and have no points in common are not called parallel planes. In this case, they are referred to as coincident lines.

Parallel planes are planes that do not intersect and are always separated by a constant distance.

If you are looking for an example of parallel planes, here's one:

- Plane 1: x + 2y - z = 4

- Plane 2: x + 2y - z + 5 = 0

Both planes have the same normal vector [1, 2, -1], and they are parallel to each other.

The probability is greater than 5%, it is not unlikely to obtain more than adults with blood type p(>4) =0.1402=14.02% and hence the result is not surprising.

In statistics, probability is the ratio of a number of possibilities in an entire sample of equal progression that produce a specific occurrence to the entire number of alternative possibilities.

Given  that n=7 p=0.44, we can use the binomial probability

\(P (X=k)= \left \ {n} \atop {k}} \right. * p^k* (1-p)^n^-^k\left\)

P(X=5)=\(\left \ {7} \atop {5}} \right. *(0.44)^5*(0.66)^7^-^5\) ≈ 0.10861

P(X=6)= \(\left \ {7} \atop {6}} \right. *(0.44)^6*(0.66)^7^-^6\) ≈ 0.0284

P(X=7)= \(\left \ {7} \atop {7}} \right. *(0.44)^7*(0.66)^7^-^7\) ≈ 0.00321

P(X>4= P(X=5) + P(X=6)+ P(X=7)

= 0.1086+0.0284+0.0032

The sum of 8 of the interior angles of a regular nonagon is 1120 degrees.

A nonagon is a polygon with 9 sides and 9 interior angles. The sum of the interior angles of any polygon is given by using the method (n-2) × 180 degrees, wherein n is the number of sides.

Therefore, the sum of the interior angles of a nonagon is (9-2) × 180 = 1260 levels.

Because the nonagon is a regular polygon, every of its interior angles has the equal degree. To discover the measure of every attitude, we will divide the sum of the interior angles through the wide variety of angles.

Therefore, the degree of every interior perspective of a ordinary nonagon is 1260/9 = 140 ranges.

To discover the sum of 8 of the interior angles, we are able to simply multiply the measure of each attitude through eight, which gives:

8 × 140 = 1120 degrees

Thus, the sum of 8 of the interior angles of a regular nonagon is 1120 degrees.

Answer:

  2. 26.2 m

  3. 117.2 cm

Step-by-step explanation:

You want the perimeters of two figures involving that are a composite of parts of circles and parts of rectangles.

The circumference of a circle is given by ...

  C = πd . . . . . where d is the diameter

The length of the semicircle of diameter 12.6 m will be ...

  1/2C = 1/2(π)(12.6 m) = 6.3π m ≈ 19.8 m

The two lighted sides of the rectangle have a total length of ...

  3.2 m + 3.2 m = 6.4 m

The length of the light string is the sum of these values:

  19.8 m + 6.4 m = 26.2 m

The length of the string of lights is about 26.2 meters.

The perimeter of the figure is the sum of four quarter-circles of radius 11.4 cm, and 4 straight edges of length 11.4 cm.

Four quarter-circles total one full circle in length, so we can use the formula for the circumference of a circle:

  C = 2πr

  C = 2π·(11.4 cm) = 22.8π cm ≈ 71.6 cm

The four straight sides total ...

  4 × 11.4 cm = 45.6 cm

The perimeter of the figure is the sum of the lengths of the curved sides and the straight sides:

  71.6 cm + 45.6 cm = 117.2 cm

The design has a perimeter of about 117.2 cm.

Answer: We can start by using the information given to find the total bill amount.

If the water/sewer/garbage portion of the bill is 72% of the total bill, then the remaining 28% of the bill must be for other utilities. We can use a proportion to set up the equation:

72/100 = 94.41/x

where x is the total bill amount.

We can cross-multiply and solve for x:

72x = 100 * 94.41

x = (100 * 94.41) / 72

x = 123.84

To the nearest cent, the total amount of the utility bill was $123.84.

Diana needs 60 grams of coffee beans to make 96 fluid ounces of coffee for her guests.

Determine whether two ratios or fractions are equivalent using the proportion formula. Dividing the provided values will reveal the value that is missing. As an example of the percentage formula: A and d are the extreme terms, while b and c are the mean terms. Hence, b::c: d = a/b = c/d.

We can resolve the issue by using proportions.

The ratio of coffee beans to liquid ounces in Diana's ordinary coffee must first be determined.

48 fluid ounces / 30 grammes

By reducing the numerator and denominator by 6, we may simplify the ratio:

Eight fluid ounces/5 grammes

We can now apply this proportion to determine how many grammes of coffee beans Diana needs to prepare 96 ounces of coffee:

Step-by-step explanation:

you do 2 1/4 times 5

Answer:

\(11\frac{1}{4}\)

Step-by-step explanation:

Given the following question:

\(2\frac{1}{4} \times5\)

Each serving takes 2 1/4 cups of fruit...
How much to make 5 servings?

To find the answer we will have to multiply 2 1/4 by 5, since we are trying to find out how much it would take to make 5 smoothies.

\(2\frac{1}{4} \times5\)
\(2\frac{1}{4} =4\times2=8+1=9=\frac{9}{4}\)
\(\frac{9}{4} \times5\)
\(5=\frac{5}{1}\)

\(\frac{9}{4} \times\frac{5}{1}\)
\(9\times5=45\)
\(4\times1=4\)
\(=\frac{45}{4}\)

Convert into mixed number:
\(\frac{45}{4}\)
\(=\frac{45}{4}=45\div4=11\frac{1}{4}\)
\(=11\frac{1}{4}\)

Which means in order to make 5 servings of the smoothie, we need "11 1/4 cups" of fruit.

Given figure is a triangular based prism. Where the triangle is right angled triangle.

So,

Hypotenuse (h) = 6.5m

Perpendicular (p) =2.5 m

Base (b) = 6m

Length of triangular prism (l) = 10m.

We have;

Lateral surface area= Perimeter*length of prism.

LSA = (6.5+2.5+6) * 10

LSA = 15*10

Therefore, LSA of the shape is 150 m².

Now, Area of base=( 1/2 )*b*p

= (1/2)*(6*2.5)

Regarding the graphs of the functions \(h(x) = x^2 - 4\) and \(g(x) = (x - 4)^2,\) the following statements are true:

The vertex of the graph of h(x) is located at (0, -4), while the vertex of the graph of g(x) is located at (4, 0).

The vertex represents the minimum or maximum point of the parabola.

The graph of h(x) opens upwards, indicating a positive coefficient for the \(x^2\)  term, while the graph of g(x) also opens upwards due to the positive coefficient of the squared term \((x - 4)^2.\)

The graph of h(x) intersects the x-axis at x = -2 and x = 2, indicating the solutions to the equation \(x^2 - 4 = 0.\)

On the other hand, the graph of g(x) intersects the x-axis at x = 4, representing the solution to the equation \((x - 4)^2 = 0.\)

It's important to note that the graph of h(x) is a standard quadratic function, while the graph of g(x) is a quadratic function with a horizontal shift of 4 units to the right.

The differences in their vertex, x-intercepts, and shape indicate these variations between the two functions.

The concepts and procedures of the scientific method that are being violated in this scenario are: a. Lack of Control Group, b. Lack of Randomization, c. Lack of Blindness, d. Failure to Replicate, e. Extraneous and Confounding Variables.

Lack of Control Group: A control group is a group that is identical to the experimental group in every way except that they do not receive the treatment. It helps in determining whether the treatment has an effect. In this scenario, the lack of a control group makes it impossible to determine whether the treatment is responsible for the difference between the experimental group and the control group.

Lack of Randomization: Randomization is the process of assigning subjects to groups randomly. It ensures that each group is identical to the others in every way except for the treatment. In this scenario, the lack of randomization makes it impossible to determine whether the differences between the experimental and control groups are due to the treatment or due to differences between the groups.

Lack of Blindness: Blinding is the process of keeping the subjects unaware of whether they are in the experimental or control group. It ensures that the subjects do not change their behavior based on their knowledge of whether they are receiving the treatment or not. In this scenario, the lack of blindness makes it impossible to determine whether the differences between the experimental and control groups are due to the treatment or due to the subjects knowing which group they are in.

Failure to Replicate: Replication is the process of repeating the study to see whether the results are consistent. In this scenario, the failure to replicate the study makes it impossible to determine whether the results are consistent with previous studies.

Extraneous and Confounding Variables: Extraneous variables are variables that are not of interest to the researcher but that may have an effect on the outcome of the study. Confounding variables are variables that are not of interest to the researcher but that are related to both the independent and dependent variables.

In this scenario, the presence of extraneous and confounding variables makes it impossible to determine whether the differences between the experimental and control groups are due to the treatment or due to these variables.

Devise a study to answer the research question in each scenario: To devise a study to answer the research question in each scenario, we must consider the concepts and procedures of the scientific method. We must include a control group, randomization, blindness, replication, and control for extraneous and confounding variables.

To conclude, lack of a control group, randomization, and blindness, failure to replicate, and the presence of extraneous and confounding variables violate the concepts and procedures of the scientific method. To answer the research question in each scenario, we must devise a study that includes a control group, randomization, blindness, replication, and control for extraneous and confounding variables.

The expectation value of the position squared when the particle in the box is in its third excited state can be calculated using the formula\(\langle x^2 \rangle = \frac{l^2}{8} \left( 2n^2 + 6n + 3 \right)\),

where n is the quantum number of the state and l is the length of the box. Here, n is 3, so the expectation value is equal to

\(\frac{l^2}{8} \left( 2 \times 3^2 + 6 \times 3 + 3 \right) = \frac{9l^2}{8}\).

(a) The answer is 360, and the problem involves a permutation.

(b) The answer is 45, and the problem involves a combination.

(a) This problem involves a permutation because the order of the digits matters. We need to determine how many 4-digit numbers can be formed without repetition from the given digits.

The number of choices for the first digit is 6 (since any of the 6 digits can be chosen). For the second digit, we have 5 choices remaining, then 4 choices for the third digit, and finally 3 choices for the fourth digit.

Therefore, the total number of 4-digit numbers without repetition is:

6 * 5 * 4 * 3 = 360

So, there are 360 different 4-digit numbers that can be made.

(b) This problem involves a combination because the order of the questions does not matter. We need to determine how many different choices the student has to answer 8 out of 10 questions on the exam.

The number of different choices can be calculated using the combination formula. The formula for combinations is:

nCr = n! / (r! * (n-r)!)

where n is the total number of items, and r is the number of items to be selected.

In this case, n = 10 (total number of questions) and r = 8 (number of questions to be answered).

Plugging the values into the formula, we have:

10C8 = 10! / (8! * (10-8)!)

10C8 = 10! / (8! * 2!)

10C8 = (10 * 9) / (2 * 1)

10C8 = 45

So, there are 45 different choices the student has to answer 8 out of 10 questions on the exam.
