Write a system of equations to describe the situation below, solve using substitution, and fillin the blanks.Nora, an office manager, needs to find a courier to deliver a package. The first courier she isconsidering charges a fee of $14 plus $5 per kilogram. The second charges $15 plus $4 perkilogram. Nora determines that, given her package's weight, the two courier services areequivalent in terms of cost. What is the weight? How much will it cost?

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 : Using trigonometric identities, this can be simplified to

Answer : 1

**Answer:**

**Step-by-step explanation:**

Using both the rotation matrices earlier in this lesson and your matrix calculator, find each determinant.: **1 and 1**

/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 =

a b

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.

**Det R = 1 **which matches the determinant for our other **translation matricies**

Find the product of the matrix and its transpose: R·Rt is** none of the above**

dollars, find a reasonable estimate for his total income during the

12 week summer.

A) $700

B) $800

C) $1200

D) $1700

1200 as you would round it down to 100 a week so you would do 100x12

The answer is 8 m by 16 m. I just answered this on my quiz.

the answer is 8 and 16

B. ASA

C. HL

D. SAS

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.

P.S. I am only answering this question so you could give the brainliest to the person who answered first :)

**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 , and a confidence interval , we have the following **confidence interval of proportions**.

**In which**

z is the zscore that has a pvalue of .

**For this problem, we have that:**

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

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

**We wish to construct a 90% confidence interval**

So , z is the value of Z that has a pvalue of , so .

The **lower limit** of this interval is:

The **upper limit** of this interval is:

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

The error bound is 3.125%.
