The condition that ensures a solution for the mentioned equation is :

1. b₂ = 2b₁ and 6b₁-3b₃ +b₄ = 0.

In mathematics, an equation is a formula that connects two expressions with the equal sign = to indicate that they are equal. An equation consists of two expressions joined by an equal sign ("="). Expressions for both sides of the equals sign are called the "left side" and the "right side" of the equation. Usually the right side of the equation is assumed to be zero. If this is accepted, it does not reduce the generality, since it can be done by subtracting the right side from the two sides.

According to the Question:

Given that:

x₁+ 2x₂= b₁       ------------------------- (1)

2x₁ + 4x₂ = b₂  ------------------------- (2)

3x₁ + 7x₂ = b₃   ------------------------ (3)

3x₁ + 9x₂ = b₄   ------------------------ (4)

From equation (1) and (2), we get:

b₂ = 2b₁

After analysis equation (1), we have:

  6b₁-3b₃ +b₄ = 0

Using equation (1), (3) and (4), we get:

3(x₁+2x₂) -6(3x₁+7x₂) + 3x₁ + 9x₂ ≠ 0

Putting the value from equation (1),(3) and (4), we get:

6(x₁+2x₂) -3(3x₁+7x₂) + 3x₁ + 9x₂ = 0

Hence option (1) is correct.

Chevrolet owners are more loyal than owners of different cars, at least based on this sample of 870 Chevrolet owners.

In order to determine if Chevrolet owners are more loyal than owners of different cars, we need to conduct a hypothesis test. Our null hypothesis (H0) would be that there is no significant difference in loyalty between Chevrolet owners and owners of different cars, while our alternative hypothesis (Ha) would be that Chevrolet owners are more loyal. To test this, we can use a one-sample proportion test, since we are comparing the proportion of Chevrolet owners who would buy another Chevrolet (56%) to the proportion of the general consumer population who are loyal to their automobile manufacturer (47%). Using a significance level of 0.05, we can calculate the test statistic and p-value. Our test statistic is: z = (0.56 - 0.47) / √((0.47 × 0.53) / 870) = 4.71
Our p-value is then calculated as the probability of obtaining a z-value of 4.71 or higher:
p = P(Z ≥ 4.71) ≈ 0
Since our p-value is less than 0.05, we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis. Therefore, we can say that Chevrolet owners are more loyal than owners of different cars, at least based on this sample of 870 Chevrolet owners.

Therefore, the angle between V and w is approximately 75.97 degrees.

To find the angle between V and w, we can use the dot product formula:

V · w = |V| |w| cosθ

where θ is the angle between the two vectors, and |V| and |w| are the magnitudes of the vectors.

First, let's calculate the dot product:

V · w = (-5)(4) + (8)(12)

= 61

Next, let's calculate the magnitudes:

|V| = √((-5)^2 + 8^2)

= √89

|w| = √(4^2 + 12^2)

= 4√5

Now we can solve for cosθ:

cosθ = (V · w) / (|V| |w|)

= 61 / (4√5 √89)

≈ 0.2577

Finally, we can find the angle θ:

θ = cos^(-1)(0.2577)

a) An unbiased estimator for λ is [tex]\hat{\lambda}=\frac{1}{n}\sum Y_i[/tex]

b) E(C) = 4λ - λ²

c) [tex]\hat{C}=4\hat{\lambda}-(\hat{\lambda})^2[/tex] is an unbiased estimator of E(C).

(a) To find an unbiased estimator for λ, we can use the sample mean. The sample mean is an unbiased estimator for the population mean of a Poisson distribution.

Therefore, an unbiased estimator for λ is:

[tex]\hat{\lambda}=\frac{1}{n}\sum Y_i[/tex]

where n is the sample size and [tex]\sum Y_i[/tex] is the sum of the observed breakdowns.

(b) The weekly cost of repairing the breakdowns is given by C = -3Y + Y². To find the expected value of C, we need to compute E(C).

E(C) = E(-3Y + Y²)

Using linearity of expectation, we can split this into two parts:

E(C) = E(-3Y) + E(Y²)

Since Y follows a Poisson distribution with mean λ, we know that E(Y) = λ.

E(C) = -3E(Y) + E(Y²)

The second term E(Y²) can be computed using the variance of Y.

Var(Y) = λ

E(Y²) = Var(Y) + (E(Y))²

= λ + λ²

= λ(1 + λ)

Substituting this back into E(C):

E(C) = -3E(Y) + E(Y²)

= -3λ + λ(1 + λ)

= λ + λ² - 3λ

= λ² - 2λ

E(C) = 4λ - λ²

Therefore, E(C) = 4λ - λ²

(c) To find an unbiased estimator of E(C), we need to find a function of Y₁, Y₂, ..., Yₙ that is an unbiased estimator of E(C). Let's call this estimator [tex]\hat{C}[/tex].

[tex]\hat{C}=4\hat{\lambda}-(\hat{\lambda})^2[/tex]

Since [tex]\hat{\lambda}[/tex] is an unbiased estimator of λ (as derived in part (a)), [tex]\hat{C}[/tex] is an unbiased estimator of E(C).

cosθ = ±√(35/36)

Now we can use a calculator to find the approximate values of θ:

[tex]θ ≈ 22.08°[/tex], 157.92°, 202.08°, 337.92°

In this case, f(x) = 1/3x^2, so f'(x) = 2/3x. Substituting these into the formula, we get S = 2π∫0^4 (1/3x^2)√(1 + (2/3x)^2) dx. Evaluating this integral, we get S = (16/3)π(√13 - 1). Therefore, the area of the surface is (16/3)π(√13 - 1). To find the surface area, we first need to express the equation of the surface in terms of a function of x, since we are rotating the curve about the y-axis. To do this, we solve the equation y = 1/3x^2 for x in terms of y: x = √(3y). Next, we use the formula for the surface area of a solid of revolution, which involves integrating the function √(1 + [f'(x)]^2) over the interval of rotation. In this case, f(x) = 1/3x^2 and f'(x) = 2/3x. Substituting these into the formula and integrating over the interval x=0 to x=4, we get the formula S = 2π∫0^4 (1/3x^2)√(1 + (2/3x)^2) dx. Evaluating this integral, we get S = (16/3)π(√13 - 1), which is the surface area of the solid of revolution.

Answer:

(1.5, 4), (2, 0.25)

Step-by-step explanation:

The question wants you to select the plotted points that are not within the group and wants them as an ordered pair. So we are going to type them in (x, y) format. The x-axis is the number of pounds and the y-axis is the price ($). Each tick on the x-axis seems to increase by 0.1 lbs. Each tick on the y-axis seems to increase by $0.25.

I see two pink spots that have ventured away from the rest of the crop (pun intended). The top spot is at 1.5 pounds and a cost of $4.00. This ordered pair would then be (1.5, 4). The bottom spot is at 2 pounds and a cost of $0.25. This ordered pair would then be (2, 0.25).

So in that box you are going to type: (1.5, 4), (2, 0.25)
If the program you are using has any rules about trailing zeros, make sure to follow those, because your answer could also technically be: (1.5, 4.00), (2, 0.25)

We can solve this problem by using a Venn diagram. Let's start by drawing two circles, one for Time and one for Newsweek:

    Newsweek

```

Let x be the number of families that subscribe to both magazines. Then, we know that:

- 75 - x subscribe to Time only

- 50 - x subscribe to Newsweek only

- 5 subscribe to neither

We want to find the value of x. We know that the total number of families surveyed is 95, so:

Total = Time only + Newsweek only + Both + Neither

95 = (75 - x) + (50 - x) + x + 5

Simplifying the equation, we get:

95 = 130 - x

x = 35

Therefore, 35 families subscribe to both Time and Newsweek.

The inverse tangent characteristic (tan^(-1) x), also known as arctan or atan, is the inverse of the tangent function. It takes a ratio as input and returns the perspective whose tangent is that ratio.

Now, allow's to analyze the expression tan^(-1) (tan 6). Since 6 radians is inside the first duration of the tangent characteristic (0 to π radians), tan 6 is defined and falls within the variety of values for which the inverse tangent function is described.

Since tan^(-1) (tan 6) is the inverse of the tangent function carried out to the value of tan 6, we will count on the expression to simplify to the unique enter attitude, that's 6 radians.

∫[3 to 4] 9f(u) du = 9 ∫[3 to 4] f(u) du

This is because we can factor the constant 9 outside of the integral, and we're left with the integral of f(u) from 3 to 4.

So, we can substitute -4 for the integral of f(x) from 3 to 4:
∫[3 to 4] 9f(u) du = 9(-4) = -36

Therefore, the definite integral of 9f(u) from 3 to 4 is -36.

∫[3 to 4] -f(u) du = -∫[3 to 4] f(u) du

To provide a margin of error of 3 or less with a 95% confidence level when the population standard deviation equals 11, we need a sample size of 73.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence.

To calculate the sample size needed to provide a margin of error of 3 or less with a 95% confidence level when the population standard deviation equals 11, we can use the following formula:

n = (Zα/2 * σ / E)²

where n is the sample size, Zα/2 is the critical value from the standard normal distribution corresponding to the desired confidence level (in this case, 1.96 for a 95% confidence level), σ is the population standard deviation, and E is the maximum margin of error.

Substituting the values given in the problem, we get:

n = (1.96 * 11 / 3)²

n = 72.85

Rounding up to the nearest whole number, we get a sample size of 73.

Answer:

y = -3x - 1

Step-by-step explanation:

Pick any 2 points on the line and find the slope, m:  

(-1, 2) and (1, -4)

m = (-4 - 2) / (1 - -1) = -6/2 = -3

The y-intercept, b,  is -1  (read it right off the graph, where the line passes through the y axis).

Equation of the line in y = mx + b form:

y = -3x - 1

The quadratic equation on the given graph is y = (x - 2)² - 9.

For a quadratic with leading coefficient a and vertex (h, k), the equation is:

y = a*(x - h)² + k

Here we can see that the vertex is at (2, -9), replacing that:

y = a*(x - 2)² - 9

We can see that the y-intercept is at y = -5, then:

-5 = a*(0 - 2)² - 9

-5 = a*4 - 9

-5 + 9 = a*4

4 = a*4

4/4 = a

1 = a

The quadratic is:

y = (x - 2)² - 9

The value(s) of x in which f’(x) = 0 are x = 0 and [tex]x= ^+_-\sqrt{2+\sqrt2}[/tex] to the hundredth place.

First we need to find the derivative of f(x) for that we can use the product rule:

we know that [tex]f(x) = (x^2 - 2)(x^2 - \sqrt2)[/tex] so the first derivative f'(x) is equal to:

[tex]f'(x) = [(x^2 - 2)(2x)] + [(x^2 - \sqrt2)(2x)][/tex]

after simplifying the derivative further, we get:

[tex]f'(x) = 2x(x^2 - \sqrt2 - 2)[/tex]

We need to find the value of x for which the function f(x) =0:

So we can set f'(x) to zero and solve for x to find what is the value of x that satisfies the given equation.

[tex]2x(x^2 - \sqrt2 - 2) = 0[/tex]

Therefore, either 2x = 0 (i.e., x = 0) or [tex]x^2 - \sqrt2 - 2[/tex] = 0.

To solve for x in the second equation we can add 2 and [tex]\sqrt2[/tex] to both sides and then take the square root of both sides:

[tex]x^2 = 2 + \sqrt2\\x = ^+_- \sqrt{2 + \sqrt2}[/tex]

Therefore, the value(s) of x in which f’(x) = 0 are x = 0 and [tex]x= ^+_-\sqrt{2+\sqrt2}[/tex] to the hundredth place.

The indefinite integral of 2x^2/47dx is (2/47)∫x^2dx which equals (2/47)(x^3/3) + C, where C is the constant of integration. To check this result, we can differentiate the obtained expression using the power rule of differentiation. The derivative of (2/47)(x^3/3) is (2/47)(3x^2/3) which simplifies to (2/47)x^2, which is the integrand we started with. Therefore, the obtained result is correct.

In summary, the indefinite integral of 2x^2/47dx is (2/47)(x^3/3) + C, where C is the constant of integration. We can check this result by taking the derivative of the obtained expression and verifying that it equals the original integrand.

since there are no elements in the empty set that can serve as a zero vector. The empty set has no elements, so it cannot have a zero vector, and thus it cannot be a vector space.

The empty set fails to satisfy the requirement that there exists a zero vector, since there are no elements in the empty set that can serve as a zero vector. Therefore, the empty set cannot be considered a vector space.
The empty set is not a vector space because it fails to satisfy the requirement of having a zero vector. A vector space must have a zero vector (also known as the identity element) that, when added to any other vector in the space, results in the original vector. The empty set has no elements, so it cannot have a zero vector, and thus it cannot be a vector space.

In sigma notation, the sum is represented as follows: ∑ (k^2 + 1), k = 1 to 2.

The given sum is: 12 + 22 + 32 + 132.

To write this sum using sigma notation, we can observe the pattern in the terms. The first term is 12, the second term is 22 (which is 12 + 1), the third term is 32 (which is 22 + 1), and the fourth term is 132 (which is 32 + 1 + 2).

We can see that each term is obtained by adding the square of the position number (k^2) to the previous term, along with an additional constant value of 1 or 2 depending on the position.

So, let's write the sum using sigma notation:

∑ [(k^2 + c(k-1))], where k starts from 1 and goes up to 4.

In this notation, k represents the position of the term, k^2 represents the square of the position number, and c represents the constant value added to the previous term.

For the given sum, the constant value c changes depending on the position of the term:

For the first term (k = 1), c is 1.

For the second term (k = 2), c is 1.

For the third term (k = 3), c is 1.

For the fourth term (k = 4), c is 2.

So, the corrected sigma notation for the given sum is:

∑ [(k^2 + c(k-1))], k = 1 to 4.

This indicates that we sum the terms (k^2 + c(k-1)) as k takes values from 1 to 4, where c changes based on the position of the term.
