n^3=7. what does n equal?

Answer:

First you find how many miles can Gavin run in 1/12 of an hour. That way you can use it to times 12 and to find 12/12 of an hour which is 1 hour.

Turn it into an improper fraction. 2×5=10 then add that 10 to the numerator 3 and it'll be 13/5 miles in 7/12 hours. Then divide it by 7.

\( \frac{13}{5} \div 7 = \\ \frac{13 }{5 \times 7} = \frac{13}{35} \)

So 13/35 is how many miles Gavin runs in 1/12 of an hour. Now times is by 12 = 146/35

Or

\(4 \frac{6}{35} \)

miles per hour

The mean monthly rent for these five apartments is $764, the median monthly rent is $800, and the mode monthly rent is $650.

To find the mean of the rents, we add all the rents and divide by the total number of rents:

Mean = (650 + 650 + 800 + 1900 + 820) / 5 = $764

The median is the middle value when the rents are arranged in numerical order. In this case, the rents arranged in numerical order are:

650, 650, 800, 820, 1900

The middle value is the third rent, which is $800.

To find Pedro's exam score, we can use the formula for calculating the z-score:

z = (x - μ) / σ,

where z is the z-score, x is the exam score, μ is the mean, and σ is the standard deviation.

Given that Pedro's z-score was 3, we can rearrange the formula to solve for x:

3 = (x - 68) / 10.

Multiplying both sides of the equation by 10, we get:

30 = x - 68.

Adding 68 to both sides, we find:

x = 30 + 68 = 98.

Therefore, Pedro's exam score was 98.

The z-score measures how many standard deviations an individual's score is above or below the mean. In this case, Pedro's z-score of 3 indicates that his exam score was 3 standard deviations above the mean of 68.

When talking about a scale drawing or model, the scale factor is determined by the ratio of a given length on the drawing or model to its corresponding length on the actual object.

This can be written as a fraction, with the length on the drawing or model as the numerator and the corresponding length on the actual object as the denominator. For example, if a drawing of a building has a scale factor of 1:100 and the length of a wall on the drawing is 5 cm, the corresponding length on the actual building would be 500 cm (5 cm x 100). Therefore, the scale factor can be written as 5/500 or simplified to 1/100.

When talking about a scale drawing or model, the term you're looking for is "scale factor." It is determined by the ratio of a given length on the drawing or model to its corresponding length on the actual object. To write this as a fraction, you would place the length on the drawing or model as the numerator and the corresponding length on the actual object as the denominator.

Step-by-step explanation:

Explanation: To multiply (-22)(-8), remember that

a negative times a negative is a positive.

So (-22)(-8) is +176.

There is no real value of x that satisfies the condition for g(x) = x + 6 to be a tangent to the curve f(x) = k√x.

To find the value of the constant k, we need to determine the point of tangency between the curve f(x) and the tangent line g(x).

The given equation for the tangent line is g(x) = x + 6. We know that the tangent line and the curve are tangent at a specific point, which means they have the same slope at that point.

To find the slope of the curve f(x), we need to differentiate it with respect to x. The derivative of f(x) = k√x is given by:

f'(x) = (1/2)(k/x^0.5) = k/(2√x)

Since the slope of the tangent line g(x) is 1, we can set the derivative of f(x) equal to 1 and solve for x:

k/(2√x) = 1

Multiplying both sides by 2√x, we get:

k = 2√x

Now we have the expression for k in terms of x. To find the value of x, we need to substitute this expression into the equation of the tangent line:

g(x) = x + 6

Substituting k = 2√x, we have:

x + 6 = 2√x

To solve this equation for x, we can square both sides:

(x + 6)^2 = (2√x)^2

Expanding the left side:

x^2 + 12x + 36 = 4x

Bringing all terms to one side:

x^2 + 12x + 36 - 4x = 0

Simplifying:

x^2 + 8x + 36 = 0

This is a quadratic equation. We can solve it by factoring or using the quadratic formula. However, upon closer inspection, we notice that the discriminant (b^2 - 4ac) is negative, indicating that the equation has no real solutions.

Therefore, there is no real value of x that satisfies the condition for g(x) = x + 6 to be a tangent to the curve f(x) = k√x.

Letters A,B,C,D

==================================================

Explanation:

Check out the diagram below to see where the lines of symmetry are located.

For the letter A, we have a vertical line through the center that is the mirroring line. Reflecting one half over that line generates the other half.

For letter B, we have a horizontal line through the center. This applies to letters C and D as well.

This is why answer choice 1 is the final answer.

-----------

For letter Z, we have neither a vertical nor a horizontal mirror line. This letter doesn't have any lines of symmetry (though it does have rotational symmetry). So we can rule out answer choice 2.

Letter N is pretty much the same idea as letter Z. There aren't any lines of symmetry but we do have rotational symmetry. So we can rule out answer choice 3.

Lastly, we can rule out answer choice 4 because letter S has the same properties as letters Z and N.

The probability of drawing a committee of 3 men and 2 women at random is 1, which means it is guaranteed to happen since there are more than enough men and women available for the committee.

To find the probability of drawing a committee of 3 men and 2 women at random from a board of directors consisting of 12 men and 6 women, we need to calculate the ratio of favorable outcomes (committee of 3 men and 2 women) to the total number of possible outcomes.

The total number of ways to select a committee of 3 men from 12 men is given by the combination formula:

C(12, 3) = 12! / (3! * (12-3)!) = 12! / (3! * 9!) = (12 * 11 * 10) / (3 * 2 * 1) = 220

Similarly, the total number of ways to select a committee of 2 women from 6 women is given by:

C(6, 2) = 6! / (2! * (6-2)!) = 6! / (2! * 4!) = (6 * 5) / (2 * 1) = 15

To find the total number of ways to select a committee of 3 men and 2 women, we multiply the above two results:

Total number of ways = C(12, 3) * C(6, 2) = 220 * 15 = 3300

The probability of selecting a committee of 3 men and 2 women can be calculated by dividing the number of favorable outcomes (committee of 3 men and 2 women) by the total number of possible outcomes:

Probability = Favorable outcomes / Total outcomes

Favorable outcomes = C(12, 3) * C(6, 2) = 3300

Probability = 3300 / 3300 = 1

Therefore, the probability of drawing a committee of 3 men and 2 women at random is 1, which means it is guaranteed to happen since there are more than enough men and women available for the committee.

The number of students in class a is 15, the mean score of class c is 5.5, and the mean score of all three classes is 6.5.

In mathematics, the mean or average is a measure of central tendency that represents the typical value or a central value of a set of numbers. It is calculated by adding up all the values in the set and then dividing by the number of values in the set. The mean is commonly used in statistics to summarize a large amount of data into a single value that is more easily understood. It is often used to represent the "average" or "typical" value of a set of data. For example, the mean score of a class on a test can give an idea of how well the class performed overall.

We can use the formula for the mean to set up two equations, one for the mean score of class a and one for the mean score of all three classes:

For class a and b combined:

(6x + 25 × 8)/ (x + 25) = 7.25

Simplifying this equation gives us:

6x + 200 = 7.25(x + 25)

Expanding the brackets and simplifying further gives:

6x + 200 = 7.25x + 181.25

Subtracting 6x and 181.25 from both sides gives:

18.75 = 1.25x

Therefore, x = 15

For all three classes:

(6x + 25 × 8 + 20y) / (x + 25 + 20) = 6.5

Substituting x = 15 into this equation gives:

(6 ×15 + 25 × 8 + 20y) / (15 + 25 + 20) = 6.5

Simplifying and solving for y gives:

(90 + 200 + 20y) / 60 = 6.5

Simplifying further gives:

y = 5.5

Therefore, the number of students in class a is 15, the mean score of class c is 5.5, and the mean score of all three classes is 6.5.

If the length of a rectangle is nine inches more than its width and its area is 442 square inches, the width of the rectangle is 17 inches and its length is 26 inches.

Let's denote the width of the rectangle as "w" and its length as "l". From the problem statement, we know that:

l = w + 9 (since the length is nine inches more than the width)

The area of the rectangle is given by the formula:

A = l * w

Substituting in the expression for "l" in terms of "w", we get:

A = (w+9) * w

Simplifying, we get a quadratic equation:

w^2 + 9w - 442 = 0

We can solve this equation by factoring or using the quadratic formula. Factoring gives:

(w+26)(w-17) = 0

Therefore, the possible values for "w" are -26 and 17. However, since the width of the rectangle cannot be negative, we can eliminate -26 as a possible value. Thus, the width of the rectangle is 17 inches.

Using the expression for "l" in terms of "w", we can find the length:
