Dividing two polynomials may produce another polynomial only when the divisor has a lower degree than the dividend. Otherwise, it will generally result in a rational function.

No, dividing two polynomials may not result in another polynomial. It can produce a rational function.

A polynomial is an algebraic expression consisting of terms with non-negative integer exponents. When two polynomials are divided, the result is not always a polynomial.

If the degree of the polynomial being divided (dividend) is higher than the degree of the polynomial dividing (divisor), then the result can be a polynomial with a lower degree. However, if the degree of the divisor is equal to or greater than the degree of the dividend, the result will generally be a rational function, which is a ratio of two polynomials.

A rational function has the form P(x)/Q(x), where P(x) and Q(x) are polynomials and Q(x) is not equal to zero. The division can introduce terms with negative or fractional exponents, making the result a rational function rather than a polynomial.

An Endure chosen randomly the likelihood of any battery lasting longer than 550 hours is 10.56%.

These steps are used to determine the Z score:

z = (x - μ)/σ

As mentioned in question-

x > 550 and μ = 500, σ = 40:

z = 550 - 500 / 40

z = 1.25

Obtain the p-value from normal distribution chart,

P(z > 1.25) = 1 - P(z < 1.25)

P(z > 1.25) = 1 - 0.8944

P(z > 1.25) = 0.1056

Step-by-step explanation:

In Chi-square analysis, we should combine categories if the expected frequencies are less than 5. The correct option is c.

When conducting a Chi-square test, we compare the observed frequencies in different categories with the expected frequencies. If the expected frequencies in any category are less than 5, it can lead to inaccurate or unreliable results.

Therefore, to ensure the validity of the analysis, it is recommended to combine categories with expected frequencies below 5 into a single category.

Combining categories helps to increase the expected frequencies, ensuring that the assumptions of the Chi-square test are met.

By combining categories, we can achieve a higher expected frequency, which improves the reliability of the test and reduces the chances of obtaining misleading or inaccurate results. The correct option is c.

Answer:

d = 10.5, a₁ = - 3.5

Step-by-step explanation:

The n th term of an AP is

\(a_{n}\) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₂ = 7 and a₄ = 28 , then

a₁ + d = 7 → (1)

a₁ + 3d = 28 → (2)

Subtract (1) from (2) term by term to eliminate a₁

2d = 21 ( divide both sides by 2 )

d = 10.5 ← common difference

Substitute d = 10.5 into (1)

a₁ + 10.5 = 7 ( subtract 10.5 from both sides )

a₁ = - 3.5 ← first term

SSR represents the amount of variation in Y that is explained in regression analysis.

It is also known as the sum of squares due to regression, which measures the difference between the predicted values and the actual values of the dependent variable (Y).

The higher the value of SSR, the better the fit of the regression line to the data. This is because a higher SSR indicates that more of the variation in Y is being explained by the independent variable (X).

Therefore, the correct answer to the multiple choice question is "The amount of variation in Y that is explained."

To evaluate the definite integral ∫[0,6] (49 - x^2) dx, we can apply the rules of integration. The antiderivative of 49 - x^2 with respect to x is (49x - (x^3)/3).

Using the Fundamental Theorem of Calculus, we can evaluate the definite integral by substituting the upper and lower limits of integration into the antiderivative:

∫[0,6] (49 - x^2) dx = [49x - (x^3)/3] evaluated from x = 0 to x = 6

Substituting the limits of integration:

[49(6) - (6^3)/3] - [49(0) - (0^3)/3]

= [294 - 72] - [0 - 0]

= 222

Therefore, the value of the definite integral ∫[0,6] (49 - x^2) dx is 222.

To verify this result using a graphing utility, one can graph the function f(x) = 49 - x^2 and use the integral feature to calculate the definite integral from 0 to 6. The result should match the evaluated value of 222.

1. The work magnitude of the force between the wires per unit length, f, can be expressed using Ampere's Law:

f = μ₀ * I₁ * I₂ / (2πd)

2. The numerical value of f is 2 × 10⁻⁶ N/m.

3. Since the currents I₁ and I₂ are both positive, the force between the wires will be attractive.

4. The minimal work per unit length needed to separate the two wires from d to 2d can be calculated using the equation:

W = f * (2d - d) = f * d.

5. The numerical value of the minimal work per unit length needed to separate the two wires from d to 2d is 1.3 × 10⁻⁷ J/m.

Ampère's law, one of the fundamental correlations between electricity and magnetism, quantifies the relationship between an electric field's changing magnetic field and the electric current that creates it.

1. The work magnitude of the force between the wires per unit length, f, can be expressed using Ampere's Law:

f = μ₀ * I₁ * I₂ / (2πd),

where μ₀ is the permeability of free space, I₁ and I₂ are the currents in the wires, and d is the separation between the wires.

2. To calculate the numerical value of f in N/m, we need to substitute the given values into the formula:

μ₀ = 4π × 10⁻⁷ T·m/A (permeability of free space)

f = (4π × 10⁻⁷ T·m/A) * (0.65 A) * (0.35 A) / (2π * 0.065 m)

Simplifying:

f = 2 * 10⁻⁶ N/m

Therefore, the numerical value of f is 2 × 10⁻⁶ N/m.

3. The force between the wires is attractive when the currents flow in the same direction and repulsive when the currents flow in opposite directions. In this case, since the currents I₁ and I₂ are both positive, the force between the wires will be attractive.

4. The minimal work per unit length needed to separate the two wires from d to 2d can be calculated using the equation:

W = f * (2d - d) = f * d.

5. Substituting the value of f (2 × 10⁻⁶ N/m) and d (0.065 m) into the equation, we get:

W = (2 × 10⁻⁶ N/m) * (0.065 m)

Simplifying:

Work = 1.3 × 10⁻⁷ J/m

Therefore, the numerical value of the minimal work per unit length needed to separate the two wires from d to 2d is 1.3 × 10⁻⁷ J/m.

So we get the number of students who like one or both the ice cream is 395 - 170 = 225.

Here it is provided that 123 children like pistachio ice cream and 175 children like chocolate ice cream.

So the total number of children who like pistachio and chocolate ice cream is 175+ 123 = 298. Which cannot be greater than 225.

The inequality that can be used to find the numbers of players the coach may chose if the coach already has 13 players is x ≤ 9.

An inequality is a mathematical statement that compares the value of two expressions using one of the following symbols: < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), ≠ (not equal to).

Inequalities are used to express relationships between numbers and can be used to describe constraints or limitations in real-world problems. They can also be used to define regions or sets of values that satisfy certain conditions. Inequalities can be solved by manipulating the expressions and isolating the variable on one side of the inequality symbol. The solution of an inequality is a set of values that make the inequality statement true.

Let x be the number of additional players the coach may choose.

We can write the inequality as:

13 + x ≤ 22

Subtract 13 from both sides:

x ≤ 22 - 13

x ≤ 9

Hence, the coach may choose between 0 and 9 additional players.

Answer: 60% or 0.6

Step-by-step explanation:

A discount simply means the amount that is deducted from the normal cost of a good or service.

In the question above, the store was offering 40% as discount, this means that he'll only pay 60% of the price of the good. Note that (100% - 40% = 60%).

Therefore, the number that he should multiply the prices on the tags by to find the price he would have to pay will be 60% = 0.6.

The expression of the current value of the stock is 1.5252x

From the question, we have the following parameters that can be used in our computation:

Initial value = x

Year 1 = Increase by 23%

Year 2 = Increase by 24%

The current value of the stock is then calculated as

Current value = Initial value * (1 + Year 1) * (1 + Year 2)

Substitute the known values in the above equation, so, we have the following representation

Current value = x *(1 + 23%) * (1 + 24%)

So, we have

Current value = x *1.5252

Lastly, we have

Current value = 1.5252x

Hence, the expression is 1.5252x
