Answer:

Add 5 to both sides.

Step-by-step explanation:

3.7 = x + (-5)

3.7 + 5 = x + ( -5) + 5

5 cancels on the right

8.7 = x

The correct step to solve an equation is add 5 to both sides. Therefore, option B is the correct answer.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 3.7=x+(-5).

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Now, 3.7=x-5

Add 5 to both sides of an equation, we get

3.7+5=x-5+5

x=8.7

The correct step to solve an equation is add 5 to both sides. Therefore, option B is the correct answer.

The solutions to the given interval 0° ≤ θ < 2π, we have:

θ = 60° and θ = 300°

We can start by dividing both sides of the equation by 2 to get sin(θ) = √3/2.

Next, we recall the special values of sin(θ) for θ in the first quadrant (0° ≤ θ ≤ 90°), where sin(30°) = 1/2 and sin(60°) = √3/2. Since our current equation has a sine value of √3/2, we know that its solution lies between 30° and 60°.

To find the exact solutions, we need to use inverse trigonometric functions. Specifically, we can take the arcsine of both sides of the equation to get:

θ = arcsin(√3/2)

Using a calculator, we find that arcsin(√3/2) ≈ 60°. Therefore, the solutions on the interval 0° ≤ θ < 360° are:

θ = 60° + 360°k, where k is an integer.

Restricting the solutions to the given interval 0° ≤ θ < 2π, we have:

There is no such value of 'a' such that f(x) = 9x² + 4 and g(x) = (3x - a)² are equivalent.

Two polynomials are said to be equivalent only when the coefficients of all powers of x are equal for both the polynomials.

In the question, we are asked is there a value of 'a' such that f(x) = 9x² + 4 and g(x) = (3x - a)² are equivalent.

We know that two polynomials are said to be equivalent only when the coefficients of all powers of x are equal for both the polynomials.

Thus to check, we expand g(x), using the formula (p - q)² = p² + q² - 2pq.

g(x) = (3x - a)²,

or, g(x) = (3x)² + (a)² - 2(3x)(a),

or, g(x) = 9x² + a² - 6ax.

For f(x) = 9x² - 4, and g(x) = (3x - a)² to be equivalent,

As we need two different values of, 'a' at the same time, which ain't possible, thus we can say that there is no such value of 'a' such that f(x) = 9x² + 4 and g(x) = (3x - a)² are equivalent.

The high R-squared value indicates that time is a strong predictor of the number of married people in the United States, it is important to consider the limitations of the equation and the uncertainty in the prediction.

First, let's talk about the R-squared value of your trendline equation.

Now, let's talk about your belief that there will never be a time when we have zero married people. This belief is not accounted for in your trendline equation, as it is purely based on your personal belief rather than any data or statistical analysis.

When it comes to confidence level, we need to consider the uncertainty in the prediction. Since we know that there will likely always be some people who want to get married, we can say with a high level of confidence that the number of married people will never actually reach zero.

In mathematical terms, we can use the equation for the confidence interval to determine the range of values within which we can be confident the true value will fall.

This equation takes into account the standard error of the estimate (the degree of variability in the data) and the desired level of confidence (typically 95% or 99%). However, since we know that the true value will never be zero, this equation is not particularly useful in this case.

Step-by-step explanation:

The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth graders. If 4/5 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.

Solution:

The total number of students = 584

Number of seventh grade students = 5/8 * total number of students = 5/8 * 584 = 365 students

Number of eighth grade students = 3/8 * total number of students = 3/8 * 584 = 219 students

Number of the seventh graders that participated in track-and-field day = 4/5 * 365 = 292 students

Number of the eighth graders that participated in track-and-field day = 7/8 * 219 = 191.625 students ≈ 192 students

Total students that participated = 292 + 192 = 484 students

When Tracey pours all the water from the smaller 5-inch cube container into the larger 7-inch cube container, the water will be approximately 7 inches deep in the larger container.

To find out how deep the water will be in the larger container, we need to consider the volume of water transferred from the smaller container. Since both containers are cube-shaped, the volume of each container is equal to the length of one side cubed.

The volume of the smaller container is 5 inches * 5 inches * 5 inches = 125 cubic inches.

When Tracey pours all the water from the smaller container into the larger container, the water completely fills the larger container. The volume of the larger container is 7 inches * 7 inches * 7 inches = 343 cubic inches.

Since the water fills the larger container completely, the depth of the water in the larger container will be equal to the height of the larger container. Since all sides of the larger container have the same length, the height of the larger container is 7 inches.

Therefore, the water will be approximately 7 inches deep in the larger container.

To find the sum of the measures of the interior angles of a convex polygon, we can use the formula:

Sum of Interior Angles = (n - 2) * 180 degrees

Where "n" represents the number of sides (or vertices) of the polygon.

For a 32-gon, substituting n = 32 into the formula, we have:

Sum of Interior Angles = (32 - 2) * 180 degrees

                      = 30 * 180 degrees

                      = 5400 degrees
