Answer:

The slope of the line is 3 ---> m = 3

Step-by-step explanation:

To find the slope of the line, you can choose any two given points from the table. Let's do (1, 3) and (2, 6)

Slope formula:  

m = (y2 - y1) / (x2 - x1)

m = (6 - 3) / (2 - 1)

m = 3 / 1

m = 3

Answer:

m = 3

Step-by-step explanation:

3 is the slope.

The part of a line that has one endpoint and can be extended infinitely in one direction is called a ray.

A ray is part of a line that starts at an endpoint and continues infinitely in one direction. It can be thought of as a beam of light or a straight path that extends indefinitely.

To visualize a ray, imagine drawing a line with an arrow at one end. The arrow indicates the direction in which the ray extends infinitely. The other end of the line is the endpoint of the ray.

It's important to note that a ray only has one endpoint and extends infinitely in one direction. This means that the other end of the ray doesn't have an endpoint and continues indefinitely.

For example, if we have a line segment AB, we can create a ray by extending it from one of its endpoints, let's say A, in the direction away from B. This would result in a ray that we can call ray AB.

In summary, a ray is part of a line that starts at an endpoint and extends infinitely in one direction. It is often represented by a line segment with an arrow at one end to indicate the direction of extension.

The demand elasticity for Netflix's pricing experiment can be calculated using the formula:Demand Elasticity = Percentage change in quantity demanded / Percentage change in price.

Given that the users who received a 20% discount were observed to be 10% more likely to join as new members, we can assume that the percentage change in quantity demanded is 10%. However, we don't have information about the percentage change in price. Without that information, it is not possible to calculate the demand elasticity.

Regarding the optimality of the current price for Netflix, we cannot determine it based solely on the given information. Demand elasticity helps measure the responsiveness of quantity demanded to a change in price, which can guide pricing strategies. If the demand elasticity is elastic (greater than 1), a decrease in price can lead to a proportionally larger increase in quantity demanded.

However, without knowing the specific price, quantity demanded, and elasticity values, it is not possible to determine whether the current price is optimal for Netflix.

Given that, Kevin works as a busboy making $10 per hour and as a theater usher making $7 per hour.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let b be the number of hours he works as a busboy this month, and let u be the number of hours he works as an usher.

His goal this month is to earn at least $1400 total.

So, the given inequality is 10b+7u≥1400

Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines. Because they are opposite each other, they are also known as vertically opposite angles.

Using Vertical Angle property as

(50+ 2x) = 150

So, subtract 50 from side we get

50 + 2x - 50= 150 - 50

2x = 100

Now, divide both side by 2 we get

2x/2 = 100 / 2

The length of the arc opposite a central angle that measures 46 degrees is 2.72 cm.

What is circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value.

The area of the cross-section of the sphere with a volume of approximately 5575.3 m³ is approximately 330.29 m².

To find the area of the cross-section of a sphere, we need the radius of the sphere. However, given only the volume of the sphere (approximately 5575.3 m³), we cannot directly determine the radius.

The volume of a sphere is calculated using the formula:

V = (4/3) * π * r³,

where V is the volume and r is the radius of the sphere.

To find the radius, we can rearrange the formula:

r = ((3 * V) / (4 * π))^(1/3).

Substituting the given volume into the formula, we have:

r = ((3 * 5575.3) / (4 * π))^(1/3).

Using the value of π as approximately 3.14159, we can calculate the radius:

r ≈ ((3 * 5575.3) / (4 * 3.14159))^(1/3) ≈ 10.25 m.

Now that we have the radius (approximately 10.25 m), we can calculate the area of the cross-section of the sphere.

The formula for the area of a cross-section of a sphere is:

A = π * r².

Substituting the radius we found, we have:

A = π * (10.25)² ≈ 330.29 m².

The area of the cross-section of the sphere with a volume of approximately 5575.3 m³ is approximately 330.29 m².

Therefore, (b) x = -10 is the result that is a solution of the rational equation that must be ignored due to the context.

Any equation in algebra that can be written in standard form as where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation. In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler. ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem. The answer could be simple or complicated.

Here,

1/x+1/(x+18)=1/40

x+18+x/x(x+18)=1/40

2x+18/x²+18x=1/40

The least amount is 98 and the greatest amount is 122 that the two friends could spend on food given that  food budget is modeled by 1/2|x-110| = 6. This can be obtained by using the definition of absolute value function.

The absolute value function is defined by:

Therefore the one example of the absolute value function is:

⇒ |x| = a means that x = a or x = -a.

Here in the question it is given that,

By simplifying the equation we get,

1/2|x - 110| = 6

Multiplying both sides by 2 we get,

⇒ |x - 110| = 6 × 2

⇒ |x - 110| = 12

By applying the definition of the absolute value function, we can write that,

x - 110 = -12 or x - 110 = 12.

x - 110 = -12

⇒ x = 98

x - 110 = 12

⇒ x = 122

Hence the least amount is 98 and the greatest amount is 122 that the two friends could spend on food given that  food budget is modeled by          1/2|x-110| = 6.

The correct option is (B) generated randomly from probability distributions.

The values for random variables in a Monte Carlo simulation are generated randomly from probability distributions.

A frequency distribution that has been idealized is a probability distribution. An individual sample or dataset is described by its frequency distribution. It's the number of times in the dataset that each possible value of a variable appears. The probability of occurrence of a value determines how frequently it appears in a sample.

A random variable can have any number of alternative values and likelihoods within a particular range, and a probability distribution is a statistical function that captures all of these possibilities. This range will be constrained by the minimum and maximum possible values, but the location of the possible value on the probability distribution will rely on a number of other variables.
