T is the linear transformation described by T(w,z) in L(C2). This indicates that the linear transformation T changes two-dimensional vectors of the type (w,z) to (-z,w).

To get T's eigenvalues, solve the equation T(v) = v, where is the eigenvalue and v is the eigenvector. By solving this equation, we discover that T's eigenvalues are λ1 = -1 and λ2 = 1.

For each eigenvalue, the associated eigenspaces are the subspaces of C2 that are spanned by the eigenvectors of T. The eigenspace is the subspace covered by the eigenvector λ1= -1 is (1,0). The eigenspace is the subspace spanned by the eigenvector λ2= 1 is (0,1).

As a result, the subspaces covered by (1,0) and (1,1) are the generalized eigenspaces corresponding to the different eigenvalues of T. (0,1).

The solution set of the system of inequalities is option a.

The system of inequalities given is:

x + y < 1

2y ≥ x - 4

To graph these inequalities, we can start by graphing the boundary lines, which are the lines that represent the equations obtained by replacing the inequality symbols with equal signs.

Now we need to determine which side of each boundary line represents the solution set of the corresponding inequality. One way to do this is to test a point that is not on the boundary line to see if it satisfies the inequality.

Since the inequality is true, we know that the solution set is on the side of the boundary line that does not contain the origin (0,0). Similarly, we can test the point (0,0) in the second inequality:

2y ≥ x - 4

2(0) ≥ 0 - 4

Since the inequality is false, we know that the solution set is on the side of the boundary line that contains the origin (0,0).

Hence the correct option is (a).

To find the component form, we can use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

where r is the magnitude of the vector and θ is the direction of the vector.

In this case, we have:

r = √33

θ = 130°

Substituting these values into the formulas above, we get:

x = √33 * cos(130°) = -3.69

y = √33 * sin(130°) = 4.40

In summary, using Z scores and a Z table, we can find that approximately 51% of respondents were married for the first time between the ages of 20 and 30, and an individual married for the first time at the age of 35 is in approximately the 97th percentile.

(a) To calculate the Z score for an observed age of 25.50, we use the formula Z = (X - μ) / σ, where X is the observed value, μ is the mean, and σ is the standard deviation. Substituting the given values, we get Z = (25.50 - 23.33) / 6.13 ≈ 0.36. The Z score tells us that the observed age is approximately 0.36 standard deviations above the mean. (b) To find the observed age associated with a Z score of -0.72, we rearrange the formula and solve for X: X = Z * σ + μ. Substituting the values, we get X = -0.72 * 6.13 + 23.33 ≈ 20.95. Thus, an observed age of approximately 20.95 corresponds to a Z score of -0.72.

(c) To calculate the proportion of respondents married between the ages of 20 and 30, we need to convert the age range to Z scores. The Z score for 20 is (20 - 23.33) / 6.13 ≈ -0.54, and the Z score for 30 is (30 - 23.33) / 6.13 ≈ 1.09. We then calculate the area under the normal distribution curve between these Z scores using a Z-table or a statistical software. This proportion represents the proportion of respondents married for the first time between the ages of 20 and 30.

(d) To determine the percentile rank for an individual married at the age of 35, we need to calculate the area under the normal distribution curve to the left of the corresponding Z score. The Z score for 35 is (35 - 23.33) / 6.13 ≈ 1.90. We then look up the corresponding percentile in a Z-table or use statistical software to find the percentage of the population with a Z score less than 1.90. This percentage represents the percentile rank for an individual married at the age of 35.

To find the sum of the first 35 terms of an arithmetic progression (A.P.), we need to use the formula for the sum of an A.P. and substitute the given values.

The formula for the sum of an A.P. is:

Sn = (n/2) * (2a + (n-1)d)

Where Sn is the sum of the first n terms, a is the first term, and d is the common difference.

Given that t2 = 2 and t3 = 22, we can determine the values of a and d.

From t2 = 2, we can write:

a + d = 2 ----(1)

From t3 = 22, we can write:

a + 2d = 22 ----(2)

Now, we can solve equations (1) and (2) simultaneously to find the values of a and d.

Subtracting equation (1) from equation (2), we get:

a + 2d - (a + d) = 22 - 2

d = 20 ----(3)

Substituting the value of d into equation (1), we have:

a + 20 = 2

a = -18 ----(4)

Now that we have found the values of a and d, we can substitute them into the sum formula to find the sum of the first 35 terms (S35).

Using the formula Sn = (n/2) * (2a + (n-1)d), we have:

S35 = (35/2) * (2*(-18) + (35-1)20)

S35 = 35 * (-36 + 3420)

S35 = 35 * (-36 + 680)

S35 = 35 * 644

S35 = 22,540

Therefore, the sum of the first 35 terms of the A.P. is 22,540.

The correct option is (1) 2510.

This helps students identify the different types of angles formed and their relationships with each other.

In hypothesis testing, data miners develop a model prior to the analysis and apply statistical techniques to data to estimate the parameters of the model.

In hypothesis testing, data miners formulate a hypothesis or a model about a population parameter based on prior knowledge or assumptions. This model specifies the relationship between variables and the expected values of the parameters. The next step is to collect data and analyze it using statistical techniques to estimate the parameters of the model.

The estimation of parameters involves using the available data to make inferences about the unknown population parameters. This can be done using various statistical methods such as maximum likelihood estimation, least squares estimation, or Bayesian estimation. These techniques aim to find the best estimates of the parameters that are consistent with the observed data and the assumptions of the model.

Once the parameters are estimated, data miners can then evaluate the goodness of fit of the model and draw conclusions about the population based on the estimated parameters. This process allows for hypothesis testing and making inferences about the population based on the sample data and the estimated parameters of the model.

The measure of the angle in degrees is approximately 713 degrees. Note that this result is greater than 360 degrees because the angle is not a standard angle in a plane but a measure in three-dimensional space.

Since 1/360th of the circumference of the circle is 0.5 cm long, the circumference of the circle is 360 times longer, or 180 cm long.

The arc subtended by the angle is 79 cm long, which is a fraction of the entire circumference. To find the angle in degrees, we need to convert the arc length to an angle measure using the formula:

angle measure = (arc length / circumference) x 360 degrees

Substituting the values we know, we get:

angle measure = (79 cm / 180 cm) x 360 degrees

Simplifying the fraction, we get:

angle measure = 1.9833 x 360 degrees

Rounding to the nearest degree, we get:

angle measure ≈ 713 degrees

Therefore, the measure of the angle in degrees is approximately 713 degrees. Note that this result is greater than 360 degrees because the angle is not a standard angle in a plane but a measure in three-dimensional space.
