Answer:

Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.

Answer: 10.875

Step-by-step explanation:

Let the short side be x.

Then the long side is 3x.

There are two opposite sides of each length, so the perimeter is

3x + 3x + x + x = 8x

The perimeter is 29, so we get the equation

8x = 29

Solve for x by dividing both sides by 8.

x = 29/8

x = 3.625

The longer side is 3x.

3x = 3(3.625) = 10.875

Answer: 10.875

Solve for x by dividing both sides by 8.

x = 29/8

x = 3.625

The longer side is 3x.

3x = 3(3.625) = 10.875

The equation in slope-intercept form is y = -3x/4 + 3.

The y-intercept is 3.

The slope is -3/4.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

Based on the information provided about this line, a linear equation that models it is given by;

y = mx + b

3x + 4y = 12

By making y the subject of formula, we have the following:

4y = -3x + 12

4y/4 = -3x/4 + 12/4

y = -3x/4 + 3

Therefore, the y-intercept is 3 and the slope is -3/4.

Answer:

(2a+1)(2a-5)

Step-by-step explanation:

Answer:

0.524

Step-by-step explanation:

To find the probability that a student participates in school sports given that the student is a male, we use conditional probability. The probability is approximately 0.624.

To find the probability that a student participates in school sports given that the student is a male, we need to use conditional probability. Conditional probability is calculated by dividing the probability of two events happening together by the probability of the given condition.

Let's denote the event of a student participating in school sports as A and the event of a student being a male as B.

The probability of a student participating in school sports and being a male is given as 0.409. The probability of a student being a male is given as 0.654. Therefore, the conditional probability of a student participating in school sports given that the student is a male can be calculated as:

P(A|B) = P(A and B) / P(B)

P(A|B) = 0.409 / 0.654 ≈ 0.624

So, the probability that a student participating in the survey participates in school sports, given that the student is a male, is approximately 0.624.

Answer:

its B

Step-by-step explanation:

Answer:

Step-by-step explanation:

The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.

The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.

A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.

The population density of Australia/Oceania is calculated by dividing the total population (3.11 × 107 people) by the total area (7.69 × 106 square kilometers), which results in a density of approximately 4.04 people per square kilometer.

To calculate the population density of Australia/Oceania, we need to divide the total population by the total area. The area of Australia/Oceania is approximately 7.69 × 106 square kilometers, and the population is approximately 3.11 × 107 people.

The calculation for population density is:

Population Density = Total Population / Total Area

So:

Population Density = 3.11 × 107 people / 7.69 × 106 square kilometers

This results in a population density of

Population Density = 4.04363 people per square kilometer (unrounded)

Rounded to the nearest hundredth, the population density is approximately 4.04 people per square kilometer.

Answer:

The width is 4

Step-by-step explanation:

If the length is 6 feet, minus 2 will be 4. Six times 4 is 24, which is the area of the afghan rug. We are multiplying 6 and 4 because it is length times width in rectangle area.

Mrs. Henson's rectangular afghan width will be 4 feet

It is the product of its length and width

How to solve this problem?

Length of afghan is 2 feet more than its width

∴ l = x+2

Area of rectangular afghan = 24 square feet

Area of rectangular afghan = lw

[tex]24=x(x+2)\\24=x^{2} +2x\\x^{2} +2x-24=0\\x^{2} -4x+6x-24=0\\(x-4)(x+6)=0\\x=4 or -6[/tex]

[tex]x=4feet[/tex]

Answer:

0.01 or 1%

Step-by-step explanation:

Find the original value of the stock by adding the amount lost to the end value.

$67.32 + $0.68 = $68.00

You would then divide the end value by the original value.

$67.32 / $68.00 = 0.99

To find what percentage the stock declined by, you would subtract.

1.00 - 0.99 = 0.01

To convert 0.01 to a percentage, you would multiply it · 100 to get 1%.
