Answer:

y = 3/2x-12

Step-by-step explanation:

The slope-intercept form of a line is

y = mx+b  where m is the slope and b is the y-intercept

The slope is 3/2 and the y-intercept is -12.

y = 3/2x-12

Answer:

\(\sf y = \dfrac{3}{2}x - 12\)

Step-by-step explanation:

The equation of a linear function can be written in the form y = m x + c, where,

m → slope → 3/2

c → y-intercept → -12

we can substitute these values into the equation.

The slope, m, is 3/2, so the equation becomes:

y = (3/2)x + c

The y-intercept, c, is -12, so we can replace c with -12:

\(\sf y = \dfrac{3}{2}x - 12\)

Therefore, the equation of the line is y = (3/2)x - 12

Planets around other stars can be detected by carefully measuring the "brightness" or "light intensity" of stars.

When a planet orbits a star, it causes a slight change in the brightness or light intensity of the star. This is known as the transit method of planet detection. As the planet passes in front of the star from our line of sight, it blocks a small portion of the star's light, causing a temporary decrease in its brightness. By carefully measuring these changes in brightness over time, scientists can infer the presence and characteristics of planets orbiting the star. This method has been instrumental in the discovery of numerous exoplanets in recent years.

The value of cosC is 15/17.

In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle. For the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that of the hypotenuse. For an angle Ɵ, the sine and cosine functions are denoted simply as sinƟ  and cosƟ.

Hence, cos Ɵ = Adjacent side/Hypotenuse side

Based on the provide information, for angle C

Opposite side (BA) = 8 units.

Adjacent side (BC) = 15 units.

Hypotenuse (AC) = 17 units.

cosC = BC/AC = 15/17

Answer:

The signs of each monomial in the second polynomial are changed.

When subtracting two polynomials, the subtraction affects each monomial in the second polynomial by inverting the sign of each coefficient. That is, every coefficient in the second polynomial is multiplied by -1.

Polynomials are mathematical expressions that contain one or more terms. These terms are made up of coefficients and variables raised to powers, like x^2, y, or z^3.

When subtracting two polynomials, we need to keep in mind that each term within the polynomial is affected.

Example: Consider the following polynomial:

2x^2 + 3xy + 4y^2

When we subtract the polynomial 3x^2 - 2xy - 5y^2 from the above polynomial, we need to invert the sign of each coefficient in the second polynomial. That is, we have:

2x^2 + 3xy + 4y^2 - (3x^2 - 2xy - 5y^2)

Now, inverting the sign of each coefficient in the second polynomial, we get:

-3x^2 + 2xy + 5y^2

So the final result is:

2x^2 + 3xy + 4y^2 - (3x^2 - 2xy - 5y^2)

= 2x^2 + 3xy + 4y^2 - 3x^2 + 2xy + 5y^2

= -x^2 + 5xy + 9y^2

The p-value can be found with the F-distribution table or statistical software. If the p-value is less than or equal to α, then answer is option (a),If the p-value is greater than α, then answer is option (b).

To determine the correct statistical decision based on the given F-statistic, F (3, 12) = 2.72, we need additional information such as the significance level (α) of the hypothesis test. The significance level is a predetermined threshold that is used to assess the statistical significance of the results.

The correct decision depends on whether the calculated p-value, which quantifies the strength of evidence against the null hypothesis, is less than or equal to the significance level (α).

To find the p-value, you would need the F-distribution table or statistical software.

Once you have the p-value, you can compare it to the significance level (α) to make a decision:

If the p-value is less than or equal to α, you would reject the null hypothesis, indicating a statistically significant mean difference.

If the p-value is greater than α, you would fail to reject the null hypothesis, suggesting that there is not a statistically significant mean difference.

Therefore, without the significance level or the p-value, it is not possible to determine the correct statistical decision.

Recent research has confirmed the Spillover Hypothesis by demonstrating a favourable association between life and job happiness.

According to the spillover hypothesis, behaviour or affect in a family system might flow immediately from one place or connection to another. Transfer takes place in the same valence, which means that one subsystem's negative affect is connected to another's negative affect, or stress at work spills over and intensifies stress at home. The compensatory hypothesis offers a different perspective by arguing that transfer between family subsystems occurs in the opposite valence, leading a person to seek fulfilment in one relationship or environment in order to make up for shortages in another.

Answer:

2 Gallons.

Step-by-step explanation:

If 8 gallons are lost in one hour, then 4 will be lost in 30 minutes. Half of thirty minutes is 15 minutes, and half of 4 is 2.

In the given proof, we are provided with a series of statements and axioms. We need to use the results from page 36 of the cheat sheet (excluding Theorem 11, which is the goal of the proof) to complete the proof. Let's analyze the steps and apply the appropriate results to complete the proof:

Proof:

1. (-a) -((a+b) (a-(ab)))

2. b-a-b

3. a-a (Axiom 6, Axiom 1, Theorem 1)

We start with the first statement: (-a) -((a+b) (a-(ab))). To simplify this expression, we can use one of the results from page 36 of the cheat sheet. Let's consider Result 5, which states: "(-a)-(b-(a-(ab))) = a-ab." By comparing the given expression with Result 5, we can see that we need to make a few adjustments to match the pattern.

We have (-a) -((a+b) (a-(ab))), and we can rewrite it as (-a) - ((a+b) - (a - (ab))). Now, we can apply Result 5, which gives us (-a) - ((a+b) - (a - (ab))) = a - (ab).

So, our first statement simplifies to a - (ab).

Moving on to the second statement: b-a-b. To prove this statement, we can utilize another result from page 36. Let's consider Result 2, which states: "a - (b - a) = 2a - b." By comparing the given expression with Result 2, we see that we need to rearrange the terms.

We have b - a - b, and we can rewrite it as b - (a - b). Now, we can apply Result 2, which gives us b - (a - b) = 2b - a.

So, our second statement simplifies to 2b - a.

Finally, we have the third statement: a - a. This statement is directly derived from Axiom 6, which states: "a - a = 0."

Combining the simplified forms of the first and second statements, we have a - (ab) = 0 and 2b - a = 0. Now, we can use these two equations along with Axiom 1, which states: "a - (ab) = (a - b)a," to derive the conclusion.

From a - (ab) = 0, we can multiply both sides by a to get a^2 - a(ab) = 0. Rearranging this equation, we have a^2 = a(ab).

Next, we substitute 2b - a = 0 into the equation a^2 = a(ab). This yields a^2 = (2b)(ab), which simplifies to a^2 = 2(ab)^2.

Using Theorem 1, which states: "If a^2 = b^2, then a = b or a = -b," we can conclude that a = √(2(ab)^2) or a = -√(2(ab)^2).

Therefore, by applying the results from page 36 of the cheat sheet and the given axioms, we have derived the conclusion that a = √(2(ab)^2) or a = -√(2(ab)^2) in the given proof.

Systematic sampling offers several advantages. It is relatively easy to implement and eliminates bias that may arise from the subjective selection of participants.

The sampling method described in the scenario is called systematic sampling.

Systematic sampling involves selecting every nth element from a population after randomly selecting a starting point. In this case, the store manager randomly chooses a shopper entering the store as the starting point and then proceeds to interview every 20th person after that initial selection.

Systematic sampling offers several advantages. It is relatively easy to implement and eliminates bias that may arise from the subjective selection of participants. By ensuring a regular interval between selections, systematic sampling provides a representative sample from the population.

However, it's important to note that systematic sampling can introduce a form of bias if there is any periodicity or pattern in the population. For example, if the store experiences a peak in customer traffic during specific time periods, the systematic sampling method might overrepresent or underrepresent certain groups of shoppers.

To minimize this potential bias, the store manager could randomly select the starting point for the systematic sampling at different times of the day or on different days of the week. This would help ensure a more representative sample and reduce the impact of any inherent patterns or periodicities in customer behavior.
