Answer:

The sum of 25 and 16 is 41.

Step-by-step explanation:

The sum of two numbers, 25 and 16, you can break apart the addends and add them separately to simplify the process. Here's how you can do it:

Break apart the numbers into their place values: For 25, you have 20 and 5, and for 16, you have 10 and 6. This step helps you work with the place values individually.

Add the tens place: In this case, you have 20 (from 25) and 10 (from 16). Adding them gives you 30.

Add the ones place: Now you add the ones place, which is 5 (from 25) and 6 (from 16). Adding them gives you 11.

Combine the sum of the tens place and the sum of the ones place: Take the sum of 30 (from step 2) and 11 (from step 3). Adding them together gives you 41.

So, the sun is 41.

Step-by-step explanation:

Halie,  find angle EAD.... see it?   next think about the definition of vertical angles: each of the pairs of opposite angles made by two intersecting lines.

which angle is EAD  an opposite pair of?   ∠IAH  looks like a good one.  

The length of the third side of the triangle is decreasing at a rate of approximately 0.22 times the sine of the changing angle (in radians) meters per second.

If the angle between the two sides of the triangle is increasing at a rate, then we can say that the triangle is changing shape. Specifically, the third side of the triangle (the one opposite the changing angle) will be changing in length as well. To determine the rate at which this side is changing, we would need to know either the measure of the changing angle or the rate at which it is increasing. With the information given, we cannot determine this rate of change. However, we can use the Law of Cosines to find the length of the third side of the triangle:
c^2 = a^2 + b^2 - 2ab cos(C)
where c is the length of the third side, a and b are the lengths of the other two sides, and C is the angle opposite side c. Plugging in the given values, we get:
c^2 = 4^2 + 5^2 - 2(4)(5)cos(C)
c^2 = 41 - 40cos(C)
c ≈ 1.07 + 6.32cos(C)
This formula tells us that the length of the third side of the triangle is a function of the angle opposite it (in radians). If we knew the rate at which this angle was changing, we could use the Chain Rule to find the rate at which the third side was changing. For example, if the angle was increasing at a constant rate of 2 degrees per second, we could convert this to radians per second (0.035 radians per second) and then find:
dc/dt = d/dt [1.07 + 6.32cos(C)]
dc/dt = -6.32sin(C) (dC/dt)
dc/dt ≈ -6.32sin(C) (0.035)
dc/dt ≈ -0.22sin(C) meters per second

The correct answer is C. Yes, the means and SDs can be combined with the Empirical Rule to summarize the distributions of these returns because each distribution is bell-shaped and approximately symmetric.

The Empirical Rule, also known as the 68-95-99.7 rule, is a statistical rule that states that for a normal distribution, 68% of the data will fall within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations. This rule can only be applied to distributions that are bell-shaped and approximately symmetric.

Option A is incorrect because the Empirical Rule cannot be applied to bimodal distributions.

Option B is incorrect because the Empirical Rule cannot be applied to skewed distributions. Option D is incorrect because it contradicts the requirements of the Empirical Rule.

Therefore, the Empirical Rule can be applied to distributions that are bell-shaped and approximately symmetric.

The correct answer to the question is b. a statistic. A population characteristic, such as a population mean, is called a statistic.

In statistics, a sample is a subset of a population that is selected for analysis, while a population refers to the entire group of individuals or objects that we want to study.

A parameter is a numerical value that describes a characteristic of a population, such as the population mean or standard deviation. On the other hand, a statistic is a numerical value that describes a characteristic of a sample, such as the sample mean or standard deviation.

Statistics play an important role in many fields, including business, economics, social sciences, and healthcare. By analyzing data from samples, statisticians can make inferences about populations and draw conclusions about relationships between variables.

For example, suppose we want to estimate the average height of all adult males in the United States. It would be impractical to measure the height of every single male in the country, so we might take a random sample of 1,000 men and calculate their average height.

This average height would be a statistic, while the true average height of all adult males in the United States would be a parameter.

A complementary angle of another angle is the angle that when you add it to that angle, you get 90 degrees.

For example, we have angle A. When we add the complementary angle of angle A, you get 90 degrees. :)

So, what we can do for this problem is create an equation! :)

x + 70.2° = "an angle"

x = complementary angle

Notice: I put the 70.2° to show the difference between the complementary angle and the angle itself.

Now, we can make an equation!

(x + 70.2°) + x = 90

2x = 19.8

x = 19.8/2

x = 9.9 degrees

One angle is 9.9 degrees, and the other angle is x + 70.2 = 9.9 + 70.2 = 80.1 degrees. We can see that when we add 9.9 and 80.1 we get 90 degrees, and when you minus 9.9 from 80.1, you get 70.2. :)

Let us consider the breadth(B) of the rectangle to be x.

So now,

Length of Rectangle(L) = 2x-3

Perimeter of Rectangle = 2 (Length + Breadth) = 2(L+B)

So according to the question,

Perimeter = 2(L+B) = 24 feet

                     L + B   = 12 feet

                     2x - 3 + x = 12 feet

                     3x - 3 = 12 feet

                        3x = 12+3

                         x = 15/3

                          x = 5 feet = Breadth

So ,                   Length = 2x - 3 = 2x5 - 3 = 10 - 3 = 7 feet

Hence the length of the Rectangle is 7 feet.

The value of x is 3/2 or 1.5.

To find the value of x, we need to equate the means of the two expressions and solve for x.

Mean of x + (x + 2) + (x + 4) = Mean of x + (x + 3x) + 3

First, let's simplify both sides of the equation:

Mean of x + (x + 2) + (x + 4) can be simplified as (3x + 6)/3, since there are three terms with equal intervals of x.

Mean of x + (x + 3x) + 3 can be simplified as (5x + 3)/3, as there are three terms with equal intervals of x.

Now, we can set up the equation:

(3x + 6)/3 = (5x + 3)/3

To remove the denominators, we can multiply both sides of the equation by 3:

3(3x + 6) = 3(5x + 3)

Expanding the brackets:

9x + 18 = 15x + 9

Next, let's isolate the x term by moving the constants to the other side:

9x - 15x = 9 - 18

Simplifying:

-6x = -9

Dividing both sides of the equation by -6:

x = -9 / -6

Simplifying further:

x = 3/2.

The solutions to the equation |w| + 10 = 17 are w = 7 and w = -7.

To solve the equation |w| + 10 = 17, we can isolate the absolute value term on one side of the equation.

1. Subtract 10 from both sides of the equation:

  |w| + 10 - 10 = 17 - 10

  |w| = 7

2. Since |w| represents the absolute value of w, we know that the expression inside the absolute value bars can be either positive or negative. Therefore, we need to consider two cases:

  Case 1: w is positive:

  In this case, |w| is equal to w.

  So we have:

  w = 7

  Case 2: w is negative:

  In this case, |w| is equal to -w (since we want the absolute value to be positive).

  So we have:

  -w = 7

3. Solve for w in each case:

  Case 1: w = 7

  Case 2: -w = 7

  For Case 2, multiply both sides of the equation by -1 to isolate w:

  -w * -1 = 7 * -1

  w = -7

Therefore, the solutions to the equation |w| + 10 = 17 are w = 7 and w = -7.

The area enclosed by the x-axis and the curve defined by x = 1 et and y = t - t² can be found using calculus. The enclosed area is approximately 1.5 square units.

To determine the area, we need to integrate the curve between the points where it intersects the x-axis. The curve intersects the x-axis when y = 0. So we set t - t² = 0 and solve for t, which gives us t = 0 or t = 1.
Next, we need to calculate the integral of the absolute value of the curve between the points of intersection with the x-axis. This is done by integrating |y| with respect to x over the range from x = 0 to x = 1.To perform the integration, we substitute the given expressions for x and y into the integral. The integral evaluates to 1.5, which gives us the enclosed area.
Therefore, the area enclosed by the x-axis and the curve is approximately 1.5 square units.

To find Vx and Vy, we need to break down the vector into its x and y components. Vx represents the horizontal component of V, while Vy represents the vertical component.

In detail, to calculate Vx, we can use the formula Vx = V * cos(θ), where V is the magnitude of the vector and θ is the angle it makes with the x-axis. Substituting the given values, we have Vx = 24.8 * cos(23.4°). Similarly, to calculate Vy, we use the formula Vy = V * sin(θ), which gives us Vy = 24.8 * sin(23.4°).

By calculating Vx and Vy using the given formulas, we can obtain the horizontal and vertical components of the vector. The values obtained will be expressed using three significant figures. To check if our calculations are correct, we can use Vx and Vy to calculate the magnitude of V using the Pythagorean theorem. The magnitude of V is given by |V| = sqrt(Vx^2 + Vy^2).

The method you are referring to is called "stepwise regression." Stepwise regression is a useful technique in identifying the most important predictors of a response variable.

Stepwise regression is a statistical technique used in linear regression analysis to identify the set of predictor variables that best explain the variability in the response variable. The technique involves sequentially removing variables that have the least impact on the model's explanatory power until a set of useful predictor variables is identified.

Stepwise regression can be performed in either a forward or backward manner. In forward stepwise regression, variables are added to the model one at a time until no more significant variables can be added. In backward stepwise regression, all variables are included in the model initially, and then variables are removed one at a time until no more significant variables can be removed. A variation of stepwise regression is the bidirectional stepwise regression, which involves both forward and backward elimination of variables. The selection of variables is usually based on their statistical significance in predicting the response variable. This can be determined by comparing the p-values of each variable's coefficient estimate against a chosen significance level (e.g., 0.05). Variables with p-values below the significance level are considered significant and are retained in the model, while variables with p-values above the significance level are removed.
