2x (to the 2nd power) +6x=0
x= (blank) and x= (blank)
Answers
Answer:
2x(x+3)=0
x=0, -3
Step-by-step explanation:
2x^2+6x=0
2(x^2+3x)=0
2x(x+3)=0
x=0, -3
first, find all the common terms/factors and divide them out of the entire term, then solve for x. If the equation is equal to 0, set each part equal to 0. In this example, it would be 2x=0 and x+3=0. for 2x=0, what times 2 is equal to 0? the answer is zero. For x+3=0 the goal would be to get x by itself on one side of the rquation. to do that we need to subtract 3 from x+3 and what you do to one side you must do to the other. 0-3= -3
suppose x1,...,xn are i.i.d. random variables from the uniform distribution on the interval [0,theta], an unbiased estimator of theta?
Answers
The required answer is = (n/(n+1))theta
theta = (n/(n+1))theta the sample maximum is an unbiased estimator of theta.
One unbiased estimator of theta is the sample maximum, which is defined as max(x1,...,xn). To show that this estimator is unbiased, we need to calculate its expected value and show that it equals theta.
Since x1,...,xn are i.i.d. random variables from the uniform distribution on the interval [0,theta], their probability density function is f(x) = 1/theta for 0 <= x <= theta and 0 otherwise.
The probability that the sample maximum is less than or equal to a given value x is the probability that all n samples are less than or equal to x. Since the samples are i.i.d., this probability is (x/theta)^n.
Therefore, the cumulative distribution function of the sample maximum is F(x) = (x/theta)^n for 0 <= x <= theta and 0 otherwise.
The probability density function of the sample maximum is the derivative of its cumulative distribution function, which is f(x) = (n/theta)(x/theta)^(n-1) for 0 <= x <= theta and 0 otherwise.
The expected value of the sample maximum is the integral of x times its probability density function from 0 to theta, which is
E[max(x1,...,xn)] = integral from 0 to theta of x*(n/theta)(x/theta)^(n-1) dx
= (n/theta) integral from 0 to theta of x^n/theta^n dx
= (n/theta) * [x^(n+1)/(n+1)theta^n)]_0^theta
= (n/(n+1))theta
Therefore, the sample maximum is an unbiased estimator of theta.
To find an unbiased estimator of theta, given that x1, ..., xn are i.i.d. random variables from the uniform distribution on the interval [0, theta], follow these steps:
1. Determine the sample maximum: Since the data is from a uniform distribution, the sample maximum (M) can be used as a starting point. M = max(x1, ..., xn).
2. Calculate the expected value of M: The expected value of the sample maximum, E(M), is given by the formula E(M) = n * theta / (n + 1).
3. Find an unbiased estimator: To find an unbiased estimator of theta, we need to adjust the expected value of M so that it equals theta. We can do this by solving for theta in the equation E(M) = theta:
theta = (n + 1) * E(M) / n
4. Replace E(M) with the sample maximum M: Since we are using the sample maximum as our estimator, we can replace E(M) with M in the equation:
theta_hat = (n + 1) * M / n
The unbiased estimator of theta is theta h at = (n + 1) * M / n, where M is the sample maximum and n is the number of i.d. random variables.

568 in. 2
Answers
Answer:
C
Step-by-step explanation:
Givens
L = 18 inches
W = 1 foot = 12 inches
H = 14 inches
Surface Area = 2 * L*w + 2*L * h + 2*w*h
Surface Area = 2 * 18*12 +2*18*14 + 2*12*14 all in linear inches
Surface Area = 432 + 504 + 336 all in square inches
Surface Area = 1272 in^2
The answer is 1,272
Step-by-step explanation:
to find the surface area of a rectangular prism you need to multiply length by width 18 x 12= 216 then multiply length by height 18 x 14= 202 then multiply width by height 12 x 14= 168 then multiply all of the products by 2. 216 x 2= 432, 202 x 2= 504, 168 x 2= 336. Then add all of the products multiplied by 2. 432+504+336=1,272. So 1,272 is the answer.

The minimum number of tons of ore that the mining company must produce to meet the contract is 44 tons.
Explanation:
A mining company owns two mines, each of which produces three grades (high, medium, and low) of ore. The company has a contract to supply a smelting company with at least 12 tons of high-grade ore, at least 8 tons of medium-grade ore, and at least 24 tons of low-grade ore.
What is the minimum number of tons of ore that the mining company must produce to meet the contract?
The mining company needs to produce at least 12 tons of high-grade ore, at least 8 tons of medium-grade ore, and at least 24 tons of low-grade ore. There are three grades of ore in total, and each mine produces three grades of ore. So, to meet the contractual requirements, the mining company will need to produce at least one ton of each grade of ore from each mine.
We know that the mining company has two mines, and both produce three grades of ore (high, medium, and low).
As a result, each mine should produce the following minimum quantities of ore:High-grade: 1 tonMedium-grade: 1 tonLow-grade: 1 tonIn total, each mine will produce three tons of ore (1 + 1 + 1).The mining company owns two mines, as previously mentioned, and each produces three tons of ore. As a result, the total ore generated by both mines will be:High-grade: 12 tons (2 × 6)Medium-grade: 8 tons (2 × 4)Low-grade: 24 tons (2 × 12)
Therefore, the minimum number of tons of ore that the mining company must produce to meet the contract is 44 tons.

In how many ways can the deck be dealt so that each player receives 5 cards, with 4 cards left in the middle, one of which is turned face-up
Answers
A deck can be dealt in 1,302,540 ways so that each player gets five cards, with 4 cards left in the middle, one of which is turned face-up.
In a game of poker, the deck of cards is dealt in many ways. In a game where each player receives five cards and 4 cards remain in the middle, one of which is turned face-up. The number of ways to deal the deck in this game is calculated as follows: First, we have to select the 5 cards that will be dealt to the first player. This can be done in C(52,5) ways.
Next, we have to select the next 5 cards that will be dealt to the second player. This can be done in C(47,5) ways. For the third player, we have to select 5 cards from the remaining 42 cards, and so on. Ultimately, the final card is selected and turned face-up, which can be done in one way. Therefore, the total number of ways to deal the deck is: C(52,5) * C(47,5) * C(42,5) * C(37,5) * C(32,5) * 4 * 1 = 1,302,540 ways.

Let the graph of g be a vertical stretch by a factor of 3 and a reflection in the y-axis, followed by a translation 2 units left of the graph of f(x)=x^2-5x+1 . Write a rule for g .
Answers
Answer:We may rewrite f(x) = (x-1)^2
We stretch by having 3(x-1)^2
We reflect about the y axis by changing x to -x: 3(-x-1)^2 = 3(x+1)^2
We move to the left by adding 2 to x: 3(x+2+1)^2 = 3(x+3)^2
Step-by-step explanation:A way to verify this: Consider y = x^2 to be the unit parabola. f(x) = (x-1)^2 moves the unit parabola one to the right, so it is symmetric about x = 1; We then vertically stretch it by a factor of 3; reflection about the y-axis moves the parabola to be symmetric about x = -1; moving to the left by 2 means the parabola is now symmetric about x = -3; thus, we have a stretched unit parabola symmetric about x = -3, so g(x) = 3(x+3)^2
We may write g(x) = 3x^2 + 18x + 27, also.

= Is the given triangle right-angled? Yes, it is right-angled. No, it is not right-angled.
Answers
The dot product of vectors QP and QR is then calculated by multiplying their corresponding components and summing them up. By comparing the dot product to zero, we can determine if the triangle is right-angled. In this case, the dot product is not zero, so the triangle is not right-angled.
To determine the vector QP, we subtract the coordinates of point P from the coordinates of point Q. Similarly, to find the vector QR, we subtract the coordinates of point R from the coordinates of point Q.
To find the vector QP, we subtract the coordinates of point P from the coordinates of point Q:
QP = (1-0, -2-(-5), -5-(-3)) = (1, 3, -2)
To calculate the vector QR, we subtract the coordinates of point R from the coordinates of point Q:
QR = (5-1, -4-(-2), -6-(-5)) = (4, -2, -1)
To find the dot product of QP and QR, we multiply their corresponding components and sum them up:
QP · QR = (1*4) + (3*-2) + (-2*-1) = 4 - 6 + 2 = 0
Since the dot product is zero, it indicates that the vectors QP and QR are perpendicular, or orthogonal, to each other. However, to determine if the triangle is right-angled, we need to consider the lengths of the sides as well. Since the dot product alone does not provide information about the lengths of the sides, we cannot conclude that the triangle is right-angled based solely on the given information. Therefore, the correct answer is that the triangle is not right-angled.

let f(x, y, z) = y² i (2xy e²) j e²y k be a vector field. a) determine whether or not f is a conservative vector field
Answers
The vector field f(x, y, z) is not a conservative vector field.
A vector field is said to be conservative if it can be expressed as the gradient of a scalar function called a potential function. In other words, if f = ∇φ, where φ is a scalar function, then the vector field f is conservative.
To determine whether the given vector field f(x, y, z) = y²i + (2xye²)j + e²yk is conservative, we need to check if its curl is zero. If the curl of a vector field is zero, then the vector field is conservative.
Taking the curl of f, we have:
curl(f) = (∂f₃/∂y - ∂f₂/∂z)i + (∂f₁/∂z - ∂f₃/∂x)j + (∂f₂/∂x - ∂f₁/∂y)k
Substituting the components of f, we get:
curl(f) = (0 - 2xe²)i + (0 - 0)j + (2xe² - y²)k
Since the curl of f is not zero (it has non-zero components), we conclude that the vector field f is not conservative.
Therefore, the given vector field f(x, y, z) = y²i + (2xye²)j + e²yk is not a conservative vector field.
