Given: The numbers of voters that are registered with a certain political party in different regions

This can't be continous because we can't figure out how many people are registered with a certain political party.

It is like tracking how many push ups you can do. You can only do a certain amount and it varies. One day you can do 10 another 6 and another day 12. It is easier to make a chart of the people in a political party than to make a graph so that eliminates A and C.

And it can't be B because it is describing continuous data so it has to be D.

Answer:

D. The data are discrete because the data can only take on specific values.

Answer:

After one unit is sold, Becky will break-even.

Step-by-step explanation:

Giving the following information:

Fixed costs= $1

Unitary variable cost= $21

Selling price= $22

The break-even point is the number of units required to cover the fixed costs after deducting from the selling price the variable components. At this point, net income is zero.

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 1 / (22 - 21)

Break-even point in units= 1

After one unit is sold, Becky will break-even.

The income of the household having mean 80,000 and standard deviation 40,000 is 1,80,000

The mean of the Household income = 80,000

The median of the Household income = 50,000

Standard deviation of the household income = 40,000

Z- score of these household income = 2.5

Thus , the income of the household can be calculated by using the normal distribution formula    

                                    Z = (X - μ) /σ

where X is the income of the household

          μ is the mean of the household income

          σ is the standard deviation of the household income.

So, we can re-write this equation as

         X = Zσ + μ

Now, let us substitute the known values in the above equation , we get

        X = 2.5(40,000) + 80,000

        X = 1,00,000 + 80,000

       X = 1,80,000

Therefore, the income of the household is 1,80,000 .

Answer:

l = 194999.45

Step-by-step explanation:

I'm going to assume that you meant 3.14 by 3,14.

336,765 = 3.14 × 0.55 × (l + 0.55)

336,765 ÷ (3.14 × 0.55) = l + 0.55

(336,765 ÷ (3.14 × 0.55)) - 0.55 = l

l = 194999.45

The annual sales of the Hand & Foot Cream are increasing by 151,000 bottles per year. Based on the linear trend equation, the predicted annual sales for year 6 is 1,006,000 bottles.

According to the given linear trend equation F1 = 80 + 151, the constant term 80 represents the initial annual sales at the start of the trend. The coefficient of the independent variable t, which represents the number of years, is 151.

To determine whether the annual sales are increasing or decreasing, we look at the coefficient of t. Since the coefficient is positive (151), it indicates that the annual sales are increasing over time. The coefficient tells us that for every year that passes, the annual sales increase by 151,000 bottles. Therefore, the annual sales are experiencing positive growth.

To predict the annual sales for year 6, we substitute t = 6 into the equation. Plugging in the value, we have F6 = 80 + (151 * 6) = 80 + 906 = 986. Therefore, the predicted annual sales for year 6 is 986,000 bottles.

In conclusion, the annual sales of the Hand & Foot Cream are increasing by 151,000 bottles per year. Based on the linear trend equation, the predicted annual sales for year 6 is 986,000 bottles. This indicates that the product's popularity and demand are growing steadily.

Answer:

490.1 in^3

Step-by-step explanation:

In order to find the volume of a cylinder, you would multiply the area of the base b the height, so a cylinder with base \(26 \pi in^{2}\) and height 6 in would be \(26\pi \times 6\)

This multiplies to 490.08845396 when put in a calculator, and rounded to the nearest tenth, the answer is 490.1 in^3

Answer: Ellipse

This cross section is not parallel to the circular base, so we get a stretched out circle of sorts. In other words, we get an ellipse.

Lattice transformation: (a) Lattice points remain linear combinations of basis vectors. (b) Volume of lattice cell is preserved. (c) Reciprocal lattice vectors inversely relate to transformation matrix. (d) Reciprocal lattice integers undergo similar transformation.

(a) In either basis, any lattice point can still be represented as a linear combination of the basis vectors with integer coefficients. This is because the transformation {a1', a2', a3'} = {a1 + ja2, a2, a3} preserves the lattice structure and the integer coefficients that describe the lattice points.

(b) The volume of the lattice cell remains the same under the basis transformation. This can be understood by considering the determinant of the transformation matrix. Since the determinant is equal to 1, the volume of the transformed cell is the same as the original cell.

(c) The reciprocal lattice vectors in the transformed basis are related to the original reciprocal lattice vectors by the inverse of the transformation matrix. If {b1', b2', b3'} are the reciprocal lattice vectors in the transformed basis, and {b1, b2, b3} are the reciprocal lattice vectors in the original basis, then {b1', b2', b3'} = {b1 + jb2, b2, b3}.

(d) The integers that describe the reciprocal lattice points also undergo a similar transformation. If (h1, h2, h3) are the integers describing a reciprocal lattice point in the original basis, and (h1', h2', h3') are the integers describing the same reciprocal lattice point in the transformed basis, then (h1', h2', h3') = (h1 + jh2, h2, h3).

In conclusion, the basis transformation in a lattice preserves the integer coefficients of lattice points, leaves the cell volume unchanged, relates the reciprocal lattice vectors by the inverse transformation, and transforms the integers describing reciprocal lattice points accordingly.

Answer: y = x + 1

Step-by-step explanation:

This is poorly written, but as i understand:

We have the general equation:

y = x + i

where i is a constant, and we want this function to pass through the point x = 2 and y = 3.

Then we must find the value of y, we know that when x= 2 we also must have y = 3, so we can replace those two values in the equation above and get

y = 3 = x + i = 2 + i

3 = 2 + i

3 - 2 = i

1 = i

So our equation is y = x + 1

However, I can provide a general explanation of the four options:

y = -2x + 5: This is a linear equation with a negative slope of -2. It represents a line that decreases as x increases. The y-intercept is 5.

y = 2x + 5: This is a linear equation with a positive slope of 2. It represents a line that increases as x increases. The y-intercept is 5.

y = -1/2x + 5: This is a linear equation with a negative slope of -1/2. It represents a line that decreases at a slower rate as x increases. The y-intercept is 5.

In this case, the highest degree term is n^7 in the numerator and n^3 in the denominator. Therefore, as n approaches infinity, the sequence grows without bound and diverges. So the answer is "diverges".

To determine if the sequence converges or diverges and find the limit, we'll analyze the given sequence a_n = n^4 / (n^3 - 9n).
Step 1: Identify the highest power of n in both the numerator and the denominator. In this case, it's n^4 in the numerator and n^3 in the denominator.
Step 2: Divide both the numerator and the denominator by the highest power of n found in the denominator, which is n^3.
a_n = (n^4 / n^3) / ((n^3 - 9n) / n^3)
Step 3: Simplify the expression.
a_n = (n) / (1 - (9/n^2))
Step 4: Take the limit as n approaches infinity.
lim n→∞ a_n = lim n→∞ (n) / (1 - (9/n^2))
As n approaches infinity, the term (9/n^2) approaches 0 since the denominator grows much faster than the numerator.
lim n→∞ a_n = lim n→∞ (n) / (1 - 0)
Step 5: Evaluate the limit.
lim n→∞ a_n = ∞

Since the limit goes to infinity, the sequence diverges. Therefore, the answer is "diverges." To determine whether the sequence converges or diverges, we can look at the highest degree term in the numerator and denominator.

The key features of the quadratic equation y = - x² - 2x + 1 is  line of symmetry is x = -1; vertex = (h, k) = (-1, 2); y-intercept is (0, 1);  

the domain = -∞ ≤ x ≤ ∞ and the range = 2 ≥ y ≥ -∞.

What are the key features of a quadratic function?

Three properties that are universal to all quadratic functions:

1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior);

2) The domain of a quadratic function is all real numbers; and

3) The vertex is the lowest point when the parabola opens upwards; while the vertex is the highest point when the parabola opens downward.

According to the given question:

The given equation is y = - x² - 2x + 1

The general vertex form is y = a·(x - h)² + k

h = -b/(2·a) = 2/(-2) = -1

k = f(h) = -(-1)² - 2×(-1) + 1 = 2

Therefore;

1) The line of symmetry goes through the vertex and the line of symmetry is x = -1

2) The vertex = (h, k) = (-1, 2)

3) The y-intercept is the coordinate of the point where x = 0 which is  

   (0, 1)

4) The domain are the possible x-values, therefore,

    the domain = -∞ ≤ x ≤ ∞

5) The range is the possible values y-values.

    On plotting the graph, we have the range = 2 ≥ y ≥ -∞
