Answer:

6√2=z

Step-by-step explanation:

As we are given a right angle we simply can apply the formula a²+b²=c².
A = 3
B = z

C =  8+1 which we add to get 9
Now, we plug this into the equation

9²=z²+3²

81=z²+9

72=z²

√72=z

√2x2x2x3x3 (expanding 72)

6√2=z

In statics the mode is the data/value that occurs most often.

Now, we have the next set of data:

-7 -6 -6 -6 -7

The number -6 occurs 3 times and the number -7 occurs twice.

Therefore, the mode is given by the number -6.

Answer: -6

Mode: The most frequent number

Step-by-step explanation:

-6 is the most frequently used number

The test statistic is 0.764

Given that,

You are evaluating the claim that night students have higher average grades than day pupils. You take a sample of 30 night students, and their mean grade point average is 2.11 with a 0.78 standard deviation. You take a sample of 55 day students, and their average grade point average is 1.98 with a 0.71 standard deviation.

H₀ : u1 <= u2

Ha : u1 > u2

n1 =30 ,n2 =55

s1 = 0.78, s2 =0.71

x1 = 2.11, x2= 1.98

t = x1 -x2 /√s1²/n1 + s2²/n2

t = 2.11 - 1.98 / √0.60/30 + 0.50/55

t = 0.13/√0.02+0.009

t =0.13 / 0.17 = 0.764.

Therefore, the test statistic is 0.764

The value of p and q in the equation are -10 and 21 respectively.

The value of p and q will be found in the equation before we can form another equation with p and q.

Therefore,

p + q = 11

2p+ q = 1

using elimination method

p = 1 - 11

p = -10

q = 11 + 10

q = 21

Therefore,

3p + 2q = 12 (let's check if its correct)

3(-10) + 2(21) = -30 + 42 = 12

Therefore, 3p + 2q = 12 is correct.

The advantages of the superposition theorem compared to other circuit theorems are its simplicity and modularity in circuit analysis, as well as its applicability to linear circuits.

Superposition theorem is a powerful tool in circuit analysis that allows us to simplify complex circuits and analyze them in a more systematic manner. When compared to other circuit theorems, such as Ohm's Law or Kirchhoff's laws, the superposition theorem offers several advantages. Here are two key advantages of the superposition theorem:

Simplicity and Modularity: One major advantage of the superposition theorem is its simplicity and modular approach to circuit analysis. The theorem states that in a linear circuit with multiple independent sources, the response (current or voltage) across any component can be determined by considering each source individually while the other sources are turned off. This approach allows us to break down complex circuits into simpler sub-circuits and analyze them independently. By solving these individual sub-circuits and then superposing the results, we can determine the overall response of the circuit. This modular nature of the superposition theorem simplifies the analysis process, making it easier to understand and apply.

Applicability to Linear Circuits: Another advantage of the superposition theorem is its applicability to linear circuits. The theorem holds true for circuits that follow the principles of linearity, which means that the circuit components (resistors, capacitors, inductors, etc.) behave proportionally to the applied voltage or current. Linearity is a fundamental characteristic of many practical circuits, making the superposition theorem widely applicable in real-world scenarios. This advantage distinguishes the superposition theorem from other circuit theorems that may have limitations or restrictions on their application, depending on the circuit's characteristics.

It's important to note that the superposition theorem has its limitations as well. It assumes linearity and works only with independent sources, neglecting any nonlinear or dependent sources present in the circuit. Additionally, the superposition theorem can become time-consuming when dealing with a large number of sources. Despite these limitations, the advantages of simplicity and applicability to linear circuits make the superposition theorem a valuable tool in circuit analysis.

Daniel's method is incorrect, as the interquartile range is given by the difference between the third quartile and the first quartile.

The interquartile range of a data-set is by the difference of the 75th percentile(Q3) by the 25th percentile(Q1) of the data-set.

The quartiles are described as follows:

From this, we get that the quartiles are related to the median of the set, that is, neither is given by the highest and by the lowest values, hence the interquartile range is given by the difference between the third quartile and the first quartile.

The volume of a stack of 9 books is 1368.75 cubic inches.

To find the volume of a stack of 9 books, we first need to find the height of the stack. Since each book is 3/4 inch thick, the height of the stack is 9 times 3/4 inch, which is 6 3/4 inches.

Now we need to find the area of the base of the rectangular prism formed by the stack of books. Since each book has an area of 22 1/2 square inches, the total area of the base of the stack is 9 times 22 1/2 square inches, which is 202 1/2 square inches.

Therefore, the volume of the stack of 9 books is:

1st programmer's salary = 109.4K

2nd programmer's salary = 89.4K

salesperson's salary = 69.4K

Let the first analyst's salary be x.

Let the second analyst's salary be y.

Third analyst's salary = (1/2) (x + y)

1st programmer's salary = y + 30K

2nd programmer's salary = (y + 30K) - 20K = y + 10K

3 analysts are paid a total of

264Kx + y + (1/2) (x + y) = 264K2x + 2y + x + y

                                      = 528K3x + 3y

                                      = 528K

=> x + y = 176K

First analyst's salary = 1.2y

2nd analyst's salary = y

3rd analyst's salary = (1/2) (x + y) = (1/2) (176K)

2nd programmer's salary = y + 10K

salesperson's salary = (y + 10K) - 20K

Total salary = 1.2y + y + 88K + y + 30K + y + 10K + y - 10K

The radian measure of angle A is (16/9)π.

To convert degrees to radians, we use the conversion factor:

\(1\ degree = \pi /180\ radians\)

Given that angle A is 320 degrees, we can calculate its radian measure as follows:

Angle A in radians = (320 degrees) * (π/180 radians/degree)

                    = (320π)/180 radians

                    = (16/9)π radians

Therefore, the radian measure of angle A is (16/9)π.

A supplement of an angle is six times as large as a complement of the angle. the measure of the angle is 72°.

To find the measure of the angle, we can use the concept of the supplementary angle and the complementary angle. So, Let's consider the angle as "x"∴ Complement of the angle = 90° - x Supplement of the angle = 180° - x According to the given statement,180° - x = 6(90° - x) ⇒ 180° - x = 540° - 6x⇒ 5x = 540° - 180°⇒ 5x = 360°⇒ x = 360°/5⇒ x = 72°.

We are given that, a supplement of an angle is six times as large as a complement of the angle. We need to find the measure of the angle. Let's consider the angle as "x".∴ Complement of the angle = 90° - x Supplement of the angle = 180° - x According to the given statement, we can write,180° - x = 6(90° - x)⇒ 180° - x = 540° - 6x.

Answer: 40% discount

Step-by-step explanation:

First lets find the difference between original price and sale price so $125-$75= $50

So we get a discount of 50 dollars off the original price

Next lets find out how much of %$125 is that $50 so \(\frac{50}{125}\) as a decimal is .4 or 40%. To check our work lets multiply 125 by 0.4 so 125*0.4= 50 which is the discount.
