Answer:

The sides of a right triangle form an arithmetic sequence with the difference is described below in detail.

Step-by-step explanation:

Let's denominate the first term aa and the obvious difference dd. Therefore, your course enhances:

a, a+d, a+2da, a+d, a+2d

Now, these three terms form the sides of a right triangle. Since a+2da+2d is the highest (considering d > 0), we can state that it is the hypothenuse.

applying the Pythagorean Theorem:

a2+(a+d)2=(a+2d)2a2+(a+d)2=(a+2d)2

a2+a2+2ad+d2=a2+4ad+4d2a2+a2+2ad+d2=a2+4ad+4d2

3d2−a2+2ad=03d2−a2+2ad=0

(3d−a)(d+a)=0(3d−a)(d+a)=0

Therefore, your solutions are

3d=a3d=a

andd=−ad=−a

So if a = 3, d = 1. Therfore, one potential  sequence is 3, 4, 5.

Similarly, if a = 6, then d = 2, so another potential sequence is 6, 8, and 10

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200

Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

Using the P-value method of testing hypotheses with a significance level of 0.05, the sample provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.

To test the claim that the mean score of job applicants from the university is greater than 160, we will perform a one-sample t-test using the P-value method. The null hypothesis (H0) assumes that the mean score is equal to 160, while the alternative hypothesis (Ha) assumes that the mean score is greater than 160.

First, we calculate the test statistic, which is the t-value. The formula for the t-value is:

t = (sample mean - hypothesized mean) / (sample standard deviation / sqrt(sample size))

Plugging in the given values, we have:

t = (183 - 160) / (12 /   √(25))

  = 23 / (12 / 5)

  = 23 * (5 / 12)

  ≈ 9.58

Next, we find the P-value associated with the test statistic. The P-value represents the probability of obtaining a test statistic as extreme as the observed value, assuming the null hypothesis is true. Since the alternative hypothesis is one-sided (greater than 160), we calculate the P-value by finding the probability of the t-distribution with 24 degrees of freedom being greater than the calculated t-value.

Consulting statistical tables or using software, we find that the P-value is very small (less than 0.0001).

Since the P-value (less than 0.0001) is less than the significance level (0.05), we reject the null hypothesis. This provides strong evidence to support the claim that the mean score of job applicants from the university is greater than 160.

Step-by-step explanation:

As a result, the area of the surface formed by rotating the given curve about the x-axis throughout the period [9, 20] is 864π.

The size of a region on a surface is measured in area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas area of a plane region or plane area refers to the area of a form or planar lamina.

Here,

The area of the surface generated when a curve is revolved about an axis is known as the surface area of revolution and can be calculated using the formula:

A = 2π ∫ y dx

where y is the equation of the curve being revolved and the integral is taken over the interval [a,b] in which the curve is being revolved.

In this case, the curve is given by y = 8√x on the interval [9, 20]. So, the surface area of revolution is:

A = 2π ∫_9^20 8√x dx

This integral can be evaluated using substitution. Let u = √x, so that du = dx / 2√x and x = u^2. Then:

A = 2π ∫_3^4 8u * 2u du

= 2π * 8 * ∫_3^4 u^2 du

= 2π * 8 * [u^3/3]_3^4

= 2π * 8 * (64/3 - 27/3)

= 2π * 8 * (37/3)

= 864π

So, the area of the surface generated when the given curve is revolved about the x-axis over the interval [9, 20] is 864π.

Answer:

  9.7 m

Step-by-step explanation:

You want the missing side of the right triangle with one leg 7 m and hypotenuse 12 m.

The Pythagorean theorem tells you the relationship between the side lengths is ...

  y² = x² + ?²

  12² = 7² + ?²

  ?² = 144 -49 = 95

  ? = √95 ≈ 9.7

The missing side is about 9.7 meters long.

<95141404393>

The value of the missing length is c = √181

From the question, we have the following parameters that can be used in our computation:

Legs = 9 and 10

Hypotenuse = c

The missing length of the triangle can be calculated using the Pythagorean Theorem represented as a​² + b² = c²​

So, we have the following equation

c² = 9² + 10²

Evaluate the sum of squares

c² = 181

Take the square root of both sides

c = √181

Hence, the missing length is c = √181

The correct option is (b) A C B.

Explanation:

(a) B n A = ∅: This option states that the intersection of class B and class A is empty. However, this is not correct because there are regular languages that can be accepted by finite automata, so there can be languages in common between the two classes.

(b) A C B: This option states that class A is a subset of class B. This is true because every language accepted by a finite automaton can be represented by a regular expression, so class A is contained within class B.

(c) A = B: This option states that class A is equal to class B. This is not correct because there are regular expressions that represent languages that cannot be accepted by finite automata. Therefore, the two classes are not equal.

(d) |A| > |B|: This option states that the cardinality of class A is greater than the cardinality of class B. It is not necessarily true as there can be an infinite number of languages represented by regular expressions and an infinite number of languages accepted by finite automata. Therefore, we cannot compare their cardinalities.

The total gain made by the Chicago Bears during the game is 18 yards.

To determine the total gain or loss made by the Chicago Bears during the football game, we need to sum up the yardages gained or lost.

The yardages gained or lost by the team are as follows:

17 yards (gain)

3 yards (gain)

-6 yards (loss)

32 yards (gain)

-11 yards (loss)

To obtain the total gain or loss, we can simply add up these yardages:

Total gain/loss = 17 + 3 - 6 + 32 - 11

Performing the addition and subtraction:

Total gain/loss = 35 - 6 - 11

Total gain/loss = 29 - 11

Total gain/loss = 18

The total gain or loss made by the Chicago Bears during the game is 18 yards.

Since the value is positive (18), it indicates a gain of 18 yards.

Professional tennis players may constitute a(n) symbolic group for an amateur tennis player

A symbolic group is one in which a person is unlikely to be accepted even if they act like a member by emulating their beliefs, attitudes, and behaviors. For young people, cricket players like Sachin Tendulkar, Sourav Ganguly, etc., may serve as a representative group. By concentrating on the small scale, symbolic interactionism examines the individual within a community and their relationships with others.

Similar to this, professional tennis players may serve as a symbolic group for an amateur tennis player who identifies with certain players by mimicking their behavior whenever possible, even though the amateur tennis player does not meet the criteria for membership in the category of professional tennis players because he or she does not have the necessary skills or access to the professional circuit.

All three reasons (1, 2, and 3) can be valid for using a normal probability model to represent the distribution of sample means.

1, 2, and 3 are correct.We can use a normal probability model to represent the distribution of sample means for the following reasons:

1. The sample is randomly selected. This ensures that each member of the population has an equal chance of being selected, reducing potential biases and allowing the use of a normal probability model.

2. The distribution of the variable in the population is normally distributed. When the population distribution is normal, the distribution of sample means will also be normally distributed, as stated by the Central Limit Theorem.

3. The sample size is large enough to ensure that sample means will be normally distributed. As the sample size increases, the distribution of sample means approaches a normal distribution, even if the original population distribution is not normal. This is also part of the Central Limit Theorem, which typically suggests a sample size of 30 or more.
