Todo Binomio es polinomio falso o verdadero? ​

Answer:

Option A

Step-by-step explanation:

Bag A: 30 cents per bag

Bag B: 31 cents per bag

In order to find Cents per bag divide the number of bags from the amount it costs.

Bag A: 6 ÷ 20 = 0.30

Bag B: 9.92 ÷ 32 = 0.31

Answer:

B

Step-by-step explanation:

I say B cost the least per bag. I divided 32 by 9.92 and 20 by 6. That gives me the answers to what each bag costs. bag A costs 3.34 for each bag and bag B costs 3.22. So bag B is cheaper.

Answer: below!

Step-by-step explanation:

9: tan51 = 8/x

x = 8/(tan51) ≅ 6.478

10: sin24 = x/31

.: x = 31sin24 ≅ 12.609

11: You've done it correctly!

12: tanx = 25/78

.: x = \(tan^-^1(\frac{25}{78} )\) ≅ 17.77°

15: Correct!

16: sin25 = 15/(XZ)

.: XZ = 15/sin25 ≅ 35.5

Since triangle WXZ is right, the pythagorean theorem tells us that WZ = \(\sqrt{22^2 + 35.5^2}\) ≅ 41.76

Now, using the Law of Sines, we can say that sin90/WZ = sinW/XZ

this means 1/41.76 = sinW/35.5

W = \(sin^-^1(\frac{35.5}{41.76} )\) ≅ 58.2°

17. Draw this image. You'll see a right triangle, with angles 90-75-15. Since the side adjacent to the 75 deg angle is 6, we can solve for the length of the ladder. in essence:

cos75 = 6/x, where x is the length of the ladder

.: x = 6/cos75 ≅ 23.18 feet

Answer:

only one triangle can be formed ...

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:

= x² + 3x² + 3x² - 6xy - 3xy + 4xy + 9y² - 4y² + 3x

= 7x² - 5xy + 5y² + 3x

The simplified form of the expression is 7x² - 5xy + 5y² + 3x.

Answer:

Its 130 mate i did this question before at my old school

Step-by-step explanation:

We are given that a marble costs 5 times as much as a sticker.  The price of each marble in terms of d is 5d cents.

To express the price of each marble in terms of d, we first need to determine the cost of the stickers.

We know that Michael paid $13 for 6 stickers.

Since each sticker costs d cents, the total cost of the stickers can be calculated as \(6 * d = 6d\) cents.
Next, we need to find the cost of the marbles.

We are given that a marble costs 5 times as much as a sticker.

Therefore, the cost of each marble can be expressed as 5 * d = 5d cents.

So, the price of each marble in terms of d is 5d cents.

Correlation measures the strength and direction of the relationship between two variables.

It quantifies how closely the variables are related to each other. The correlation coefficient is a statistical measure that ranges between -1 and 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation.

Regression:

Regression analysis is a statistical technique used to model and analyze the relationship between a dependent variable and one or more independent variables. It helps in understanding how the independent variables influence or predict the dependent variable. Regression analysis estimates the parameters of a mathematical equation that best fits the data and allows us to make predictions or draw conclusions based on the relationship between variables.

Types of Correlation:

1. Positive Correlation: In positive correlation, as one variable increases, the other variable also tends to increase. The correlation coefficient is positive, ranging from 0 to 1.

2. Negative Correlation: In negative correlation, as one variable increases, the other variable tends to decrease. The correlation coefficient is negative, ranging from 0 to -1.

3. No Correlation: No correlation means that there is no relationship between the variables. The correlation coefficient is close to 0.

Properties of Regression:

1. Linearity: Regression assumes a linear relationship between the independent and dependent variables.

2. Independence of Errors: The errors or residuals in regression should be independent of each other, meaning that there should be no systematic pattern or relationship among them.

3. Homoscedasticity: Homoscedasticity means that the variance of the residuals should be constant across different levels of the independent variables.

4. Normality of Residuals: The residuals in regression should follow a normal distribution.

5. No Multicollinearity: Multicollinearity occurs when there is a high correlation between independent variables, which can lead to problems in interpreting the coefficients.

These properties ensure the validity and reliability of the regression analysis and allow us to make accurate inferences and predictions based on the regression model.

the indefinite integral of e^4x sin(3x) is (1/7)e^(4x) cos(3x) - (9/28)e^(4x) cos(3x) + C.

To solve this integral, we can use integration by parts, with u = sin(3x) and dv/dx = e^(4x). Then, we have:

du/dx = 3 cos(3x)

v = (1/4)e^(4x)

Using the formula for integration by parts, we get:

∫e^4x sin (3x) dx = -(1/4)e^(4x) cos(3x) + (3/4)∫e^4x cos (3x) dx

Now, we can apply integration by parts again, this time with u = cos(3x) and dv/dx = e^(4x):

du/dx = -3 sin(3x)

v = (1/4)e^(4x)

Using the formula for integration by parts, we get:

(3/4)∫e^4x cos (3x) dx = (3/4)[(1/4)e^(4x) cos(3x) - (3/4)∫e^4x sin (3x) dx]

Substituting this back into the original equation, we get:

∫e^4x sin (3x) dx = -(1/4)e^(4x) cos(3x) + (9/16)e^(4x) cos(3x) - (27/16)∫e^4x sin (3x) dx

Simplifying, we get:

(28/16)∫e^4x sin (3x) dx = (1/4)e^(4x) cos(3x) - (9/16)e^(4x) cos(3x)

Dividing both sides by 28/16, we get:

∫e^4x sin (3x) dx = (1/7)e^(4x) cos(3x) - (9/28)e^(4x) cos(3x) + C

where C is the constant of integration.

On solving the provided question, we can say that from the given figure, angle x = 120-68 = 52

An angle is a form in Euclidean geometry made composed of two rays, called the angle's sides, that meet at a point in the middle known as the angle's vertex. In the plane where the rays are placed, two rays can produce an angle. An angle is also produced when two planes intersect. They're known as dihedral angles. In plane geometry, an angle is the form that two rays or lines with a common termination might take. The Latin word "angulus," which means "horn," is where the English word "angle" comes from. The two rays, also known as the sides of the angle, have a common termination known as the vertex.

The width of the aquarium is approximately 0.078125 feet or 0.9375 inches.

To find the width of the aquarium, we need to use the formula for volume, which is:

Volume = Length x Width x Height

We know that the volume of the aquarium is 33.75 gallons, or approximately 127.7 liters. We also know that the length is 2 feet and the height is 1.5 feet. So we can plug in these values and solve for the width:

127.7 liters = 2 feet x Width x 1.5 feet

To simplify the equation, we can convert the liters to gallons and the feet to inches:

33.75 gallons = 24 inches x Width x 18 inches

Now we can solve for Width:

Width = 33.75 gallons / (24 inches x 18 inches)

Width = 33.75 / 432

Width = 0.078125 feet

Therefore, the width of the aquarium is approximately 0.078125 feet or 0.9375 inches.

Answer:

47.5°

Step-by-step explanation:

(2x+10)°+75°= 180°------ sum of angles of a triangle

or, (2x+10°)=180°-75°

or, (2x+10°)=105°

or, 2x=105°-10°

or,2x=95°

or, x= 95÷2

therefore, x=47.5°

Answer:

x=21.25

Step-by-step explanation:

The lower two angles will be equal in an isosceles triangle and all angles in a triangle add up to 180 degrees so:

75+(2x+10)+(2x+10)=180

75+4x+20=180

4x=85

x=21.25

(both lower angles=52.5 degrees)

Proof:

52.5+52.5+75=180

The expected number of visitors to  buy more than one costume is 48.

64 visitors purchased no costume,

376 purchased exactly one costume.

The number of visitors who purchased more than one costume is 47 .visitors

Total visitors visited the website

= 64visitors + 376 visitors + 47

= 487

Out of the 487 visitors who purchased at least one costume, 376 purchased exactly one costume.

To estimate how many visitors would buy more than one costume out of the expected 500 visitors,

Use the concept of proportions,

47 visitors / 487 visitors = x visitors / 500 visitors

Cross-multiplying, we get,

⇒x visitors = 500 visitors ×  47 visitors / 487 visitors

Simplifying this expression, we get,

⇒ x visitors = 48.2546 visitors

⇒ x visitors ≈ 48 visitors (Rounding to the nearest whole number)

Therefore, the expected number of about 48 visitors to buy more than one costume out of the 500 expected visitors.
