Answer:

x = 3

Step-by-step explanation:

First, you should put what is shown into an equation, which would be:

x + x + x + x + x + 2 = 17 or 5x + 2 = 17

Next, you subtract by two on both sides o the equation to isolate the variable x:

5x = 15

Now, you can divide by five on both sides to find the actual value of x:

x = 3

For the eigenspace -1 {B}, the basis vectors are [-1 2 0]T and [-1 0 1]T. The matrix A can be orthogonally diagonalized as A = PDP-1 where P is the orthonormal matrix whose columns are the eigenvectors of A, and D is the diagonal matrix containing the eigenvalues of A.

The eigenspace of the matrix A is the set of all eigenvectors associated with a particular eigenvalue. Given the matrix A = 6 6 -2 -2 6 -1 with eigenvalues λ = 3, 6, and 8. The eigenvectors of A are obtained by solving the equation (A - λI)x = 0, where λ is the eigenvalue and I is the identity matrix.

For λ = 3, we have (A - 3I)x = 0. Substituting A and I, we get the matrix equation:

3x1 - 6x2 - 2x3 = 0
-2x1 + 3x2 - 2x3 = 0
-2x1 - 2x2 + 3x3 = 0

Solving this system of equations, we get two linearly independent solutions, which form a basis for the eigenspace of λ = 3. These basis vectors are given by [-1 2 0]T and [-1 0 1]T. For λ = 8, we have (A - 8I)x = 0. Substituting A and I, we get the matrix equation:

-2x1 + 6x2 - 2x3 = 0
-2x1 - 2x2 - 2x3 = 0
-2x1 - 2x2 - 9x3 = 0

Solving this system of equations, we get one linearly independent solution, which forms a basis for the eigenspace of λ = 8. This basis vector is given by [0 1 4/3]T. To orthogonally diagonalize A, we need to find an orthonormal basis for the eigenspace of A. The orthonormal basis can be obtained by normalizing the basis vectors obtained above.

The orthonormal basis for λ = 3 is given by

v1 = [-1/√2 1/√2 0]T
v2 = [-1/√6 0 1/√3]T

The orthonormal basis for λ = 8 is given by

v3 = [0 1/√2 1/√2]T

The orthonormal matrix P is then given by

P = [v1 v2 v3]

The diagonal matrix D is given by

D = diag(3, 6, 8)

Finally, we can compute the orthogonally diagonalized matrix A as

A = PDP-1

where P-1 is the inverse of P, which can be computed as the transpose of P since P is an orthonormal matrix.

Step-by-step explanation:

A data set has a mean of 177 and a standard deviation of 20. 11.3% is the coefficient of variance for this collection of data.

The ratio of a data set's standard deviation to its mean, stated as a percentage, is represented by a coefficient of variation (CV), a dimensional measure of variability. It is a practical tool for contrasting the relative variance of two or more data groups with various means or measurement units.

We divide the usual level deviation by the mean, multiply the result by 100, and that number is the coefficient of variation. The coefficient in variation can be computed as follows in this situation: Using the formula CV = (standard deviation / mean) x 100, (20 / 177) x 100, and 11.3%

A low coefficient for variation means that the mean is a good indicator of the data and that the set of data has low relative variability. On the other hand, a high coefficient for variation shows substantial relative variability, which could point to the need for additional research or alternate metrics of central tendency.

When we calculate probabilities involving one event AND another event occurring, we multiply their probabilities.

According to me , independent is the word which is associated with multiplication when computing probabilities . Because when the events are independent then we multiply the probabilities .

According to the multiplication rule of probability, the probability of occurrence of both the events A and B is equal to the product of the probability of B occurring and the conditional probability that event A occurring given that event B occurs.

The probability of the union of two events is equal to the sum of individual probabilities. The union of two set contains all the elements of previous sets. The union is denoted by ∪. The equation for the students earnings will be expressed as P(A∪B). The occurrence of event A changes the probability of B then the events are dependent. If the probability of two events happening together is zero then the events are mutually exclusive.

The sides of the triangle JKL from least to greatest would be

JK,

KL, and

JL.

To find the order of the sides of ΔJKL from least to greatest, we need to use the angle-side relationship in triangles

In a triangle, the largest angle is always opposite the longest side, and the smallest angle is opposite the shortest side.

The sum of the angles in a triangle is always 180°, so:

m∠J + m∠K + m∠L = 180

(2x + 6) + (10x - 11) + (3x - 10) = 180

15x - 15 = 180

15x = 195

x = 13

Now we can find the measures of all three angles:

m∠J = (2x + 6)° = 32°

m∠K = (10x - 11)° = 119°

m∠L = (3x - 10)° = 29°

Next, we can use the angle-side relationship to find the order of the sides:

Side opposite the smallest angle: JK

Side opposite the largest angle: KL

So, the sides of ΔJKL in order from least to greatest are JK, JL, KL.

Answer:

a. 677

Step-by-step explanation:

Add the three scores, 690+ 691+651 then divide by 3

equals to 677.3 so by rounding to the nearest whole point it’s 677.

The mean credit score of Ned is 677. The correct answer would be option (A).

The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

The formula for the mean of a given set of data is as follows:

Mean = Sum of Observations/Total number of observations

The mean credit score of Ned can be calculated by adding all three credit scores and dividing the sum by 3.

So, (690 + 691 + 651) / 3

= 2032 / 3

= 677.33

Rounding to the nearest whole point, we get

= 677

Therefore, the mean credit score of Ned is 677.

Answer: hmmm

Step-by-step explanation:

The probability that the sample proportion will differ from the population proportion by greater than 4% is 0.990.

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

µ = p

The standard deviation of this sampling distribution of sample proportion is:

σ = √p(1-p)/n

The information provided is:

p = 0.14

n = 41

As the sample size is large, i.e n = 411 > 30. the central limit theorem can be used to approximate the sampling distribution of sampling proportion.

Compute the values of P(p^ - p >0.04) as follows:

P(p^ - p < 0.04) = P(p^-p/σ > 0.04/√0.14(1-0.14)/411

= P(Z>2.33)

= 0.990

Thus the probability that the sample proportion will differ from the population proportion by greater than 4% is 0.990

To conclude, the probability of the Acme Drug Company seeing a percent difference of -.13 or less if the true difference is 0 is quite low and is equal to 0.0934.

The probability that the Acme Drug Company would see a percent difference of -.13 or less if the true difference is 0 is quite low. This is because a difference of -.13 is a very small percentage in comparison to a true difference of 0.

Mathematically, the probability of this happening would be equal to the area under the standard normal distribution curve for values between -0.13 and 0. In other words, the probability that the Acme Drug Company would see a percent difference of -.13 or less if the true difference is 0 is equal to the area from the left tail of the standard normal distribution curve up to the mean (0) of the curve.

Using a standard normal distribution calculator, we can see that the probability of the Acme Drug Company seeing a percent difference of -.13 or less is 0.0934. This probability is extremely low and it is not likely that the Acme Drug Company would experience such a small percent difference.

The probability that their mean weight gain during freshman year is between 0 kg and 3 kg is 0.7207, rounded to four decimal places.

To solve this problem, we can use the central limit theorem, which states that the sample mean of a large enough sample taken from a population with any distribution approaches a normal distribution.

Let X be the weight gain of a male college student during freshman year. Then X follows a normal distribution with mean μ = 1.3 kg and standard deviation σ/√n = 5.6kg/√16 = 1.4 kg (since we have a sample size of 16).

Let Y be the sample mean weight gain of 16 male college students during freshman year. Then Y also follows a normal distribution with mean μ = 1.3 kg and standard deviation σ_Y = σ/√n = 1.4 kg.

To find the probability that their mean weight gain during freshman year is between 0 kg and 3 kg, we need to standardize the values using the z-score formula:

z = (x - μ) / σ_Y

For x = 0 kg:

z1 = (0 - 1.3) / 1.4 = -0.93

For x = 3 kg:

z2 = (3 - 1.3) / 1.4 = 1.21

Using a standard normal distribution table or calculator, we can find the area under the curve between z1 and z2:

P(-0.93 < Z < 1.21) = 0.7207

Therefore, the probability that their mean weight gain during freshman year is between 0 kg and 3 kg is 0.7207, rounded to four decimal places.
