Step-by-step explanation:

just did the assignment

next question : Find the following determinant by hand.

answer is : 1

Next question : In mathematics, a pattern may suggest a conclusion, but it is not proof of it. Next you will prove that the determinant of a rotation matrix (CCW about the origin) must be 1. Luckily, there is the general rotation matrix you can use.

Answer : cos^2x + sin^2x

/next question: In the lesson, you used the following matrices to create reflections

Answer: All these reflections resulted in CONGRUENT figures.

next question: Find the determinant of each of these: answer:   - 1

next question: A • At =

c d

 where At is the transform of A. answer: a=1 b=0 c=0 d=1

next question: Repeat this process for the other three matrices. The product of a reflection matrix and its transpose is the identity matrix

Choose the correct choice for the matrix after applying the transformation to the triangle: A

The resulting matrix creates an image that is  to the original triangle.: not similar

Find the determinant of the rotation matrix.

What property allows us to determine the congruency of the two triangles in the diagram?A. SSS
B. ASA
C. HL
D. SAS

Answers

A. SSS

That is because the diagram only shows that the sides are congruent and does not show anything else. (Like angles or anything)

The correct answer is A.SSS.

According to a poll, 76% of California adults (385 out of 506 surveyed) feel that education is one of the top issues facing California. We wish to construct a 90% confidence interval for the true proportion of California adults who feel that education is one of the top issues facing California. Find the error bound. (Round your answer to three decimal places.)

Answers

Answer:

The error bound is 3.125%.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence interval 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{(\pi(1-\pi))/(n)}

In which

z is the zscore that has a pvalue of 1 - (\alpha)/(2).

For this problem, we have that:

A sample of 506 California adults.. This means that n = 506.

76% of California adults (385 out of 506 surveyed) feel that education is one of the top issues facing California. This means that \pi = 0.76

We wish to construct a 90% confidence interval

So \alpha = 0.10, z is the value of Z that has a pvalue of 1 - (0.10)/(2) = 0.95, so z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{(\pi(1-\pi))/(n)} = 0.76 - 1.645\sqrt{(0.76*0.24)/(506)} = 0.7288

The upper limit of this interval is:

\pi + z\sqrt{(\pi(1-\pi))/(n)} = 0.76 + 1.645\sqrt{(0.76*0.24)/(506)} = 0.7913

The error bound of the confidence interval is the division by 2 of the subtraction of the upper limit by the lower limit. So:

EBM = (0.7913 - 0.7288)/(2) = 0.03125

The error bound is 3.125%.
