What are the integer solutions to the inequality below?

\(10 \leq 2x \leq x+7\)

Answer:

A

Step-by-step explanation:

Apply Quotient of Powers

\( \frac{x {}^{y} }{x {}^{z} } = x {}^{y - z} \)

In this questions terms,

\( \frac{a {}^{ \frac{1}{3} } }{a {}^{ \frac{1}{4} } } = a {}^{ \frac{1}{3} - \frac{1}{4} } \)

\( \frac{4}{12} - \frac{3}{12} = \frac{1}{12} \)

Answer:

12.1

Step-by-step explanation:

y=a(1/2)^t/h

270=410(1/2)^t/20

Divide both sides by 410

0.6585365854 = (1/2)^t/20

Log Both sides

Log(0.6585365854) / Log(1/2)

.6026645024= t/20

20 x .6026645024 = t

12.05329005 to the nearest tenth is 12.1 = t

8° + 6x is an exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.

In this situation, those two angles are 30° and 4x+2°

So lets put this in an equation

30° + 4x + 2° = 8° + 6x

4x + 32° = 6x + °8

Now lets subtract 8° from both sides to make it simpler

New equation =

4x + 24° = 6x

Lets evaluate X=

6x - 4x = 24°

2x = 24°

x= 24/2

x= 12°

Answer: 36.56

Step-by-step explanation:

To solve the equation, first acknowledge that the radius of the quarter circle shown at the top of the figure is 4 cm, so the rectangle's dimensions are 4 by (10-4) or 4 by 6, meaning the area is 24 cm^2.

Then address the circle, with an area of pi * r^2.

pi * r^2

3.14 *(4)^2

3.14 * 16

50.24

Then, because the figure shows 1/4 of a circle, divide 50.24 by 4.

50.24/4

12.56

Then add 24 to 12.56 to get 36.56.

An erroneous data observation in a multiple regression analysis would most likely show up as an outlier.

In a multiple regression analysis, an erroneous data observation typically manifests itself as an outlier. An outlier refers to a data point that deviates significantly from the overall pattern or trend observed in the dataset. It lies far away from the majority of the data points and can have a substantial impact on the regression model's results and interpretation.

When performing a multiple regression analysis, the goal is to establish a relationship between the dependent variable and multiple independent variables. Outliers can distort this relationship by exerting disproportionate influence on the regression model's coefficients and overall fit. As a result, the inclusion of an outlier in the analysis can lead to inaccurate estimates of the regression coefficients and biased predictions.

Identifying and addressing outliers is crucial in maintaining the integrity and reliability of the regression analysis. Various techniques can be employed to detect outliers, such as visual inspection of scatter plots, examining residual plots, calculating standardized residuals, leverage values, or influential observations. Once an outlier is detected, it can be handled through various methods, including excluding the observation from the analysis, transforming the data, or applying robust regression techniques that are less sensitive to outliers.

In summary, an erroneous data observation in a multiple regression analysis is most likely to manifest itself as an outlier—a data point that deviates significantly from the general pattern observed in the dataset. Detecting and appropriately addressing outliers is essential for ensuring accurate and reliable regression model results.

Step-by-step explanation:

As θ ∈ [0, 2π), we have another solution at θ = 2π. Thus, this gives n solutions.

Given: n ∈ Z and n > 2, prove that z¯ = zn−1 has n+1 solutions.

Proof:Let z = r(cos θ + i sin θ) be the polar form of z, where r > 0 and θ ∈ [0, 2π).Then, zn = rⁿ(cos nθ + i sin nθ)and, z¯ = rⁿ(cos nθ - i sin nθ)

Now, z¯ = zn−1 will imply that: rⁿ(cos nθ - i sin nθ) = rⁿ(cos (n-1)θ + i sin (n-1)θ).

As the moduli on both sides are the same, it follows that cos nθ = cos (n-1)θ and sin nθ = -sin (n-1)θ.

Thus, 2cos(θ/2)sin[(n-1)θ + θ/2] = 0 or cos(θ/2)sin[(n-1)θ + θ/2] = 0.

As n > 2, we know that n - 1 ≥ 1.

Thus, there are two cases:

Case 1: θ/2 = kπ, where k ∈ Z. This gives n solutions.

Case 2: sin[(n-1)θ + θ/2] = 0. This gives (n-1) solutions.

However,as [0, 2], we have a different answer at [2:2].

Thus, this gives n solutions.∴ The total number of solutions is n + 1.

Step-by-step explanation:

Answer:

Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87. Answer: Isabella buys 2 paintbrushes and 3 jars of paint.

The system of equations corresponding to each graph is given as follows:

The solution to a system of equations on a graph is given by the point of intersection between the two equations.

The first system is given as follows:

Equaling the equations, we have that:

4x + 2 = 3x + 2

Hence they intersect at point (0,2), which is represented by Graph 2.

The x-value of the solution of the second system is given as follows:

3x = x + 3

2x = 3

x = 1.5.

Then the solution for y is of:

y = 3x = 3(1.5) = 4.5.

They intersect at point (1.5, 4.5), which is represented by Graph 1.

For x-value of the solution of the third system is given as follows:

2x + 1 = x + 2

x = 1.

Then the solution for y is of:

y = x + 2.

y = 3.

Meaning that they intersect at point (1,3), which is represented by Graph 3.

For x-value of the solution of the fourth system is given as follows:

2x - 2 = x - 2

x = 0.

They intersect at (0,-2), which is not represented by any graph.

For x-value of the solution of the fifth system is given as follows:

2x + 3 = x + 5

x = 5 - 3

x = 2.

The equation to represent the given situation is 1/2X-5=11-5/6 using X as the variable.

What is an equation and how it can be formed?

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

When we are given a mathematical problem that is or may be described using algebraic expressions, we form and solve equations. The information from the situation and the algebraic expressions can be used to create an equation. The equation can then be solved to obtain the answer.

Given the situation: If 5 is lessened by 1/2 of a number the result is the same as subtracting 5/6 from 11.

To write an equation for the given situation.

Let the number be X.

If 5 is lessened by 1/2 of the number, we get the expression 1/2X-5

Subtracting 5/6 from 11 gives the expression 11-5/6

Now, it is given that both the situations are same so equating both the expressions we get,

1/2X-5=11-5/6

⇒1/2X-5=61/6

Hence, the equation to represent the situation is 1/2X-5=11-5/6.

Walking and running both require energy, but the distance covered and the time taken are different. In this case, the person covers the same distance of 1 km in both segments.

Therefore, the energy used is the same for both. However, since running involves covering the same distance in less time, the power while running is greater. Power is the rate at which energy is used, and since running takes less time, the power output is higher.

Answer:

I think may be it is Option 2 (AB)

a) A horizontal pattern may be seen in the data. It indicates that throughout time, statistics have moved erratically around the average value.

b) MSE is relatively low when alpha is 0.9.

A time series is a statistical or visual representation of points over a period of time that happen in a particular order. Investors who trade in stocks, commodities, or other financial market items can benefit greatly from time series.

Following is a time series. (Image is attached)

The information is organized horizontally. It indicates that throughout time, there is a random movement of data around the average value.

b.) To get the alpha value leading to a lower MSE, the forecast value for months 2 and 3 must be determined.

Second-month forecasted value:

= αY1 + (1 − α) × forecast value of first month

= 0.2 × 7.35 + 0.8 × 7.35

= 7.35

Values predicted during the third month

=αY2 + (1 − α) × forecast value of second month

= 0.2 × 7.40 + 0.8 × 7.35

= 7.36

MSE calculation with alpha = 0.2 (Table is attached as an image)

MSE = (n∑t = k + 1) et² / n − k

= 0.15374651 / (10 − 1)

= 0.017

Where,

MSE = Mean squared error

n = Number of periods in time series

k = Number of periods at the beginning of the time series

et = Forecast period for t

MSE calculation with alpha = 0.9 (Table is attached in the image section)

MSE = (n∑t = k + 1) et² / n − k

= 0.007654524 / (12 − 3)

= 0.009
