The diameter of Earth in kilometers is approximately 12,682 km, making option D the correct answer.

To convert the diameter of Earth from miles to kilometers, we can multiply the given diameter in miles by the conversion factor of 1.6 kilometers per mile.

Given that Earth's diameter is 7,926 miles, we can calculate its diameter in kilometers as follows:

Diameter in kilometers = Diameter in miles × Conversion factor

Diameter in kilometers = 7,926 miles × 1.6 kilometers/mile

Diameter in kilometers = 12,681.6 kilometers

Rounding this value to the nearest whole number, we get 12,682 kilometers.

Therefore, the correct answer is option D: 12,682 km.

Option A: 49,553 km is not the correct answer. It is not consistent with the given diameter of Earth.

Option B: 120,586 km is also not the correct answer. It is not consistent with the given diameter of Earth.

Answer:

Decreased

Strong negative

Step-by-step explanation:

The correlation Coefficient is used to show the strength and type of relationship which exists between the dependent and independent variable. The correlation Coefficient value ranges from - 1, to 1. With values closer to either - 1 or 1 depicting a strong relationship while those closer to 0 represents weak relationship. And correlation Coefficient of 0 indicates that no relationship exiata at all. Depending in the sign, that is positive or negative, positive sign means positive relationship while a negative sign represents a negative association. Positive association is interpreted as, for every increase in A, Variable B also increase and vice versa. For negative association, When A increases, B decreases and vice versa

Based on the given information, the terminal side of angle 0 lies in quadrant III.

To determine the quadrant in which the terminal side of angle 0 lies based on the given information, we can analyze the signs of the trigonometric functions:

(a) Since sine < 0 and cotangent < 0, we can determine the quadrant as follows:

Sine < 0 implies that the y-coordinate (vertical component) of the point on the unit circle corresponding to angle 0 is negative.

Cotangent < 0 implies that the x-coordinate (horizontal component) of the point on the unit circle corresponding to angle 0 is negative.

In quadrant III, both the x and y-coordinates are negative. Therefore, quadrant III is the correct answer in this case.

(b) The information provided in this option is incorrect. "esce" is not a recognized trigonometric function, and "cos > 0" does not provide enough information to determine the quadrant.

The probability of the value of  (0.21) distribution using the normal distribution table is: 0.3166

What is Probability?

Calculating the likelihood of experiments happening is one of the branches of mathematics known as probability. We can determine everything from the likelihood of receiving heads or tails when tossing a coin to the likelihood of making a research blunder, for instance, using a probability. It is crucial to grasp this branch's most fundamental concepts in order to fully comprehend it, including the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc.

In the question, we have

Probability of (0.21 < z <1.28)

= P(z < 1.28) - P(z < 0.21)

Probability of value for z

= 1.28 using z table is 0.8997

=> P(z < 1.28)

= 0.8997

probability of value for z = 0.21

Now, find the value of the probability using the normal distribution table:

using the z table of 0.21; we get:

The value of z is: 0.5832

=> P(z < 0.21) = 0.5832;

The value of  Probability of (0.21 < z <1.28)

= Probability of (z < 1.28) - Probability of (z < 0.21)

= 0.8997 - 0.5832

= 0.3165

Answer: 97

Step-by-step explanation: hope this is right.

The simplified form of the linear equation y =10(0.91)x is y = 9.1x.

To solve the equation y = 10(0.91)(x), we can simplify the expression on the right side of the equation.

First, we can multiply 10 and 0.91:

y = 9.1x

Now, we have a simple linear equation in the form y = mx, where m represents the slope of the line. In this case, the slope is 9.1.

This equation represents a line with a slope of 9.1 and a y-intercept of 0. The value of y depends on the value of x. For each increase of 1 in x, y will increase by 9.1.

To find specific solutions, you can substitute different values for x and solve for y. For example:

If x = 1, then y = 9.1(1) = 9.1

If x = 2, then y = 9.1(2) = 18.2

The equation y = 9.1x represents a line that increases at a rate of 9.1 units in the y-direction for every 1 unit increase in the x-direction. The line passes through the origin (0,0) and has a positive slope, indicating a positive relationship between x and y.

1.The amount of Interest Earned will be; $157.17.

2. It will take 7.8 years to to build up a fund of $17000 by saving $360 at the end of every month at 2.7% compounded monthly

Simple Interest is the amount of return that someone receives on the amount invested in a bank or in a business. The annual interest rate can be defined as the invested amount.

1. From the interest rate on the principal amount, we can find the annual interest earning.

Principal = $3,100

Therefore, Rate of simple interest = 2.7% per year

Now, to define the total time period.

Time period = 18 months

Time period = 18 / 12

Time period = 1.5 years

Now finding the Total interest earning.

Interest Earned = $3,100 x 2.7% x 1.5

Interest Earned = $157.17

2. Now we have \(A = P(1 + r/n)^{n\times t}\)

Where A is the amount, P is the principal,r is the rate of interest,

Substituting the given 360 = 17000 (1 + 0.027/365)^(365×t)10000/3000

          = (1.000073972)^(365×t)10/3

          = (1.000073972)^(365×t)in the formula we get,

\(360 = 17000 (1 + 0.027/365)^{365t}10000/3000\\ = (1.000073972)^{365t}10/3\\ = (1.000073972)^{365t}\)

Answer:

There are 20 rabbits.

Step-by-step explanation:

Let D be the number of ducks on the farm and R be the number of rabbits. We get the equation:

D + R = 24

Ducks have 2 legs and rabbits have 4. We know there are 88 legs in total, so we get the equation:

2D + 4R = 88

Rewriting the first equation, we get:

D = 24 - R

Substituting this into the second equation, we get:

2(24 - R) + 4R = 88

Solve for R:

48 - 2R + 4R = 88

2R = 40

R = 20

So there are 20 rabbits and 4 ducks on the farm, with a total of 88 legs.

A ∩ B = {5}

Step-by-step explanation:

A ∪ B means all the elements in sets A and B without repetition

A ∩ B means the common elements in the two sets A and B

∵ Set A = {5, 6, 7, 8, 9, 10}

∵ Set B = {2, 3, 4, 5, 11, 12, 13}

→ To Find A ∪ B, write all the elements in the two sets but don't

   repeat the common element

∵ 5 is a common element in the two sets

∴ Don't repeat it in A ∪ B

∴ A ∪ B = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

→ To find A ∩ B, write the common elements in the two sets

Both functions are decreasing and have the same rate of change.

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

Explanation:

The slope intercept form is y = mx+b

The first equation y = -2x-3 has slope m = -2, which is the rate of change.

--------------------

Let's find the slope of the line through (0,0) and (3,-6)

\((x_1,y_1) = (0,0) \text{ and } (x_2,y_2) = (3,-6)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-6 - 0}{3 - 0}\\\\m = \frac{-6}{3}\\\\m = -2\\\\\)

Or you can use the shortcut that m = y/x = -6/3 = -2. This shortcut only works when the line goes through the origin. We divide the nonzero x,y values.

The slope of the second line is the same as the first line's slope.

Both lines have the same rate of change.

Both lines are decreasing due to the negative slope value.

Visually, each line goes downhill as we move from left to right.

--------------------

Side note: Both lines have the same slope (-2), but different y intercepts. This makes the lines parallel.

The choice where y is a nonlinear function of x is option C: x y x + = −.

In this equation, the relationship between x and y is not a simple direct proportion or linear function. The presence of the exponent on x indicates a nonlinear relationship.

As x increases or decreases, the effect on y is not constant or proportional. Instead, it involves a more complex operation, in this case, the squaring of x and then subtracting it. This results in a curved relationship between x and y, which is characteristic of a nonlinear function.

Nonlinear functions can have various shapes and patterns, including curves, exponential growth or decay, or periodic behavior.

These functions do not exhibit a constant rate of change and cannot be represented by a straight line on a graph.

In contrast, linear functions have a constant rate of change and can be represented by a straight line.

The volume of the triangular prism is 216 cubic meters.

To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.

Calculate the area of the triangular base.

The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.

Plugging in the values, we get:

Area = (1/2) * 8 meters * 9 meters = 36 square meters.

Multiply the area of the base by the length of the prism.

The length of the prism is given as 12 meters.

Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.

Adjust for the shape of the prism.

Since the prism is a triangular prism, we need to divide the volume by 2.

Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.

Therefore, the volume of the triangular prism is 216 cubic meters.

Step-by-step explanation:

The outputs of each inequality are the numbers directly next to the parentheses. If an "x" value lies within a particular inequality, the values of the function are the corresponding output.

Remember, the "greater than or equal to" sign (≤) indicates that the "x" value can be equal to the number on the left. The "greater than" symbol (<) indicates that the number to the right cannot satisfy the inequality.

x = -2 lies within the inequality -2 ≤ x < 4. All "x" values that fall within this range are g(x) = 0. Therefore, g(-2) = 0.

x = 4 lies within the inequality 4 ≤ x < 10. All "x" values that fall within this range are g(x) = -4. Therefore, g(4) = -4.

Given that 60% of the 258 young adults said the U.S. is ready for a woman president.

we have p = 0.60.

Since we want a 90% confidence interval, the z-score is 1.645 (corresponding to a 90% confidence level).

CI = 0.60 ± 1.645 × √(0.60 (1 - 0.60)) / 258)

Calculating the expression inside the square root:
