2x + 6+ 3y +5

need help asap using distributive property

Answer:

Step-by-step explanation:

Let the consecutive even integers be 2n and 2n+2.

lesser integer = 2n

Greater integer = 2n+2

If twice the lesser of two integers is 4 less than two times the greater integer, this is expressed mathematically as;

2(less integer) = 2(greater integer) - 4

Substituting the given integers;

2(2n) = 2(2n+2)-4

2(2n) = 2[(2n+2)-2]

2n = 2n+2-2

2n = 2n

2 = 2

This two values cancels out and become 0 = 0. This equality shows that it is an identity pair and it is true for all even integers.

1.625 rounded to the nearest hundredth is 1.63.

When rounding 1.625 to the nearest hundredth, we look at the digit in the thousandths place, which is 5. Since the digit in the hundredths place is 2, we round up to 3. Therefore, 1.625 rounded to the nearest hundredth is 1.63.

A number line can be a helpful tool for visualizing the rounded value. We can mark the point for 1.62 and 1.63 on a number line and see that 1.625 falls closer to 1.63. This demonstrates how rounding works by approximating a number to the nearest value with a given number of decimal places.

Rounding can be a useful tool for simplifying numbers and making calculations easier, but it is important to use appropriate rounding methods and to consider the impact of rounding errors on the accuracy of calculations.

The constant term that is necessary to complete the perfect square trinomial pictured in the algebra tile is 16.

A perfect square trinomial is an algebraic statement with three terms of the type ax²+bx+c. It is calculated by multiplying a binomial with itself.

For the given trinomial to be a perfect square trinomial, the value of the constant term should be such that the value of the term expression must be similar to (a+b)². Therefore,

\((a+b)^2=a^2+2ab+b^2\)

            \(=x^2+8x+16\)

Now, if we compare the two equations we will understand that the first term of the perfect square trinomial is x, and thus, the last term should 16.

\((x+4)^2=x^2+8x+16\)

Hence, the constant term that is necessary to complete the perfect square trinomial pictured in the algebra tile is 16.

The probability that Rickenbacker Airlines will receive a specific number of complaints on a given day can be determined using the Poisson distribution, given an average of 3 complaints per day.

To find the probability of receiving a specific number of complaints, we can use the Poisson distribution formula:

P(X = x) = (e^(-λ) * λ^x) / x!

Where:

P(X = x) is the probability of receiving x complaints

λ (lambda) is the average number of complaints per day

e is the base of the natural logarithm (approximately 2.71828)

x is the number of complaints we want to find the probability for

x! denotes the factorial of x

In this case, the average number of complaints per day is given as 3. Therefore, the probability of receiving a specific number of complaints can be calculated as follows:

P(X = x) = (e^(-3) * 3^x) / x!

For example, if we want to find the probability of receiving exactly 2 complaints in a day:

P(X = 2) = (e^(-3) * 3^2) / 2!

= (2.71828^(-3) * 3^2) / 2!

By plugging in the values into the formula and performing the calculations, we can determine the specific probability.

Similarly, we can calculate the probabilities for other numbers of complaints by substituting different values of x into the formula.

If the null hypothesis is true and there is no treatment effect, the expected value on average for the F-ratio would be 1.00. The correct answer is option (b) 1.00

In hypothesis testing using the F-test, the F-ratio is calculated by dividing the variance between groups (treatment effect) by the variance within groups (random variation). When the null hypothesis is true and there is no treatment effect, the numerator (variance between groups) and the denominator (variance within groups) would be similar, resulting in an F-ratio close to 1.

Therefore, the correct answer is b. 1.00, as the expected value for the F-ratio would be around 1 when the null hypothesis is true and there is no treatment effect.

The match can be scheduled in 900 different ways.

Here, the number of players from each school = 3.

Let us assue that the players of the first school be A, B, and C.

And the players of the second school be X, Y, and Z.

Here, each player from the first school has to play twice with each player from the second school.

We can organize the schedule into six different rounds, i.e.,

R1 : AX BY CZ

R2 : AX BZ CY

R3 : AY BX CZ

R4 : AY BZ CX

R5 : AZ BX CY

R6 : AZ BY CX

So, the number of possible ways to do this would be : 6! = 720 ways.

Now, three rounds are played simultaneously in each round.

R1 : AX BZ CY

R2 : AX BZ CY

R3 : AY BX CZ

R4 : AY BX CZ

R5 : AZ BY CX

R6 : AZ BY CX

And R1 : AX BY CZ

R2 : AX BY CZ

R3 : AY BZ CX

R4 : AY BZ CX

R5 : AZ BX CY

R6 : AZ BX CY

The total number of possible ways for the second case would be twice of  6! / (2! 2! 2!), which is equal to 90+ 90 = 180.

Therefore, the total number of ways in which the match can be scheduled is 720 + 180 = 900.

Step-by-step explanation:

The Area of the composite figure = area of the rectangle + area of the triangle = 148.5 cm².

The figure formed by the arrow can be decomposed into a rectangle and a triangle.

The area of the composite figure = area of the rectangle + area of the triangle.

Find the area of the rectangle:

Length = 12 cm

Width = 11 cm

Area of the rectangle = (length)(width) = (12)(11)

Area of the rectangle = 132 cm²

Find the area of the triangle

Base = 11 cm

Height = 15 - 12 = 3 cm

Area of the triangle = 1/2(b)(h) = 1/2(11)(3)

Area of the triangle = 16.5 cm²

To convert 6 3/4 meters to centimeters, we need to multiply the value by 100.

First, convert the mixed number to an improper fraction:

6 3/4 = (6 * 4 + 3)/4 = 27/4

Now, multiply the fraction by 100:

(27/4) * 100 = 675/2 = 337.5

Therefore, 6 3/4 meters is equal to 337.5 centimeters.

y = -2x - 13

Step-by-step explanation:

Answer:

y = - 2x - 13

Step-by-step explanation:

First, distribute out the two on the right side of the equation.

y + 7 = - 2x - 6

Next, subtract 7 from both sides to isolate the y variable on the left side.

y = - 2x - 13

That is your answer in slop-intercept form.

Volume of item 1,2&3 is respectively explained below:

Object #1: Rotating about the y-axis, y = 0 and y = -23x + 6z!

To find the volume of this object, we can use the disk method since it is rotating about the y-axis. We'll integrate with respect to x and z.

The base radius of the object is 3 cm, so we can express x as a function of y: x = sqrt(3^2 - (y/23 + 6z!)^2).

The bounds of integration will be determined by the range of y-values over which the object exists. However, the equation y = -23x + 6z! alone does not provide enough information to determine the exact bounds for this object.

Object #2: Rotating about the x-axis, cylindrical shells, widest shell has 10 cm diameter, solid except for 1 cm radius inside, 1 = 0 and 3 = }y? + 2

To find the volume of this object, we'll use the cylindrical shell method. We'll integrate with respect to y.

The inner radius of the shell is 1 cm, and the outer radius is given by the equation 3 = sqrt(y^2 + 2).

The bounds of integration for y can be determined by the intersection points of the curves defined by the equations 1 = 0 and 3 = sqrt(y^2 + 2).

Object #3: y = 1 * = -1, 1 = 1, y = 5sec^2, rotating about the x-axis

To find the volume of this object, we need to integrate with respect to x.

The object extends from x = -1 to x = 1, and the height is given by y = 5sec^2.

Now, let's calculate the unused portion of polymer clay:

Unused clay volume = Total clay volume - (Volume of Object #1 + Volume of Object #2 + Volume of Object #3)

To create an integral for a specific volume, we need to specify the desired volume and determine the appropriate bounds of integration based on the shape of the object. However, without specific volume constraints, it's challenging to provide a precise integral for a specific volume in this context.

Now, it's time for you to get creative and design the fourth object using integration to utilize the remaining clay. You can define the shape, bounds of integration, and calculate its volume. After creating the fourth object, you can send it back to the curator to see if she can identify which one doesn't represent the real artifact.

Remember, the fourth object is an opportunity for you to explore your imagination and design a unique shape using calculus techniques.
