Step 1: Define

Point (-9, 9)

Point (3, 9)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Answer:

This question has a slope of zero.

Step-by-step explanation:

When trying to solve a problem like this, what I recommend doing is subtracting the y value in the first ordered pair from the y value in the second ordered pair, and doing the same for the x values. To write it as a formula,

y2 - y1

––––– = m          the 2 in the formula means that the y or x value was from the  

x2 - x1                  second ordered pair. The 1 means it was from the first                                      

                            ordered pair. The m means slope.

The posterior distribution of λ given the observed data x is a gamma distribution with parameters n+α and Σxi + β, where n is the number of data points, α and β are parameters of the prior distribution, and Σxi represents the sum of the observed data

To find the posterior distribution of λ|x, we need to apply Bayes' theorem. Bayes' theorem states:

P(λ|x) = (P(x|λ) * P(λ)) / P(x)

Here, P(λ|x) represents the posterior distribution of λ given the observed data x. P(x|λ) is the likelihood function, P(λ) is the prior distribution of λ, and P(x) is the marginal likelihood or evidence.

To proceed, we need to specify the likelihood function and the prior distribution of λ.

Assuming that the data x1, x2, ..., xn are independent and identically distributed (i.i.d.) random variables from an exponential distribution with parameter λ, the likelihood function is given by:

P(x|λ) = λ^n * exp(-λ * Σxi)

Let's assume a conjugate prior for λ, which is the gamma distribution with parameters α and β:

P(λ) = (β^α / Γ(α)) * λ^(α-1) * exp(-βλ)

where Γ(α) is the gamma function.

Now, we can substitute these expressions into Bayes' theorem to obtain the posterior distribution:

P(λ|x) = (λ^n * exp(-λ * Σxi) * (β^α / Γ(α)) * λ^(α-1) * exp(-βλ)) / P(x)

Simplifying this expression and dropping the terms that are not related to λ, we can write the posterior distribution as:

P(λ|x) ∝ λ^(n+α-1) * exp(-(λ * Σxi + β))

To obtain the exact posterior distribution, we need to normalize it by dividing by the appropriate constant to ensure that it integrates to 1.

Therefore, the posterior distribution of λ given the observed data x is a gamma distribution with parameters n+α and Σxi + β.

Step-by-step explanation:

Answer:

ok

1 divide the area A÷ 3.1416

2 find the square root of the number for example 3×3=9 so the square root of 9 is 3

3 the results is you radio.

4 do this formula 2×3.1416× the number you got.

The calculated value of the expression x² + y² + 8 is 12 - 2xy

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

x + y + 2 = 0

This can be expressed as

x + y = -2

Using the sum of two squares, we have

x² + y² = (x + y)² - 2xy

So, we have

x² + y² = (-2)² - 2xy

Evaluate

x² + y² = 4 - 2xy

Add 8 to both sides

x² + y² + 8 = 12 - 2xy

Hence, the value of the expression x² + y² + 8 is 12 - 2xy

If you are trying to find the missing measures of a rectangle, you should know that all rectangles have four sides, and each side has a length.

In other words, if you have a rectangle, two of the angles must be 90 degrees, and the other two angles must also be 90 degrees. To find the missing measures of a rectangle, you need to use the properties of rectangles.

First, find the length of each side. The length of all sides of a rectangle should be the same. Then, calculate the area of the rectangle. You can do this by multiplying the length of one side with the length of the other side.

Finally, you can use the Pythagorean Theorem to find the missing measures.

The Pythagorean Theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

Using this theorem, you can find the length of the hypotenuse of the rectangle.

Kelli spends 75 minutes studying math over a 5-day period.

Kelli studies for 45 minutes per night, with 1/3 of her time devoted to math.

To find how many minutes she spends on math, multiply 45 minutes by 1/3:

45 * (1/3) = 15 minutes per night.

To determine the total time spent on math in 5 days, multiply 15 minutes by 5:

15 * 5 = 75 minutes.

Based on the calculation, Kelli studies for 5 nights, so she spends 15 minutes x 5 nights = 75 minutes studying math in 5 days.

Step-by-step explanation:

The correct option is C. a designed experiment is one for which the analyst controls the specification of the treatments and the method of assigning the experimental units to each treatment. An observational study is one for which the analyst observes the treatments and the response on a sample of experimental units.

In a designed experiment, the analyst has control over the treatments being studied and the method of assigning the experimental units to each treatment. This allows them to actively manipulate and control the variables of interest.

On the other hand, in an observational study, the analyst simply observes the treatments and the response on a sample of experimental units without actively controlling or manipulating any variables. The distinction lies in the level of control the analyst has over the experimental setup and data collection process.

Explanation:

Let's call the unknown number x.

Four times this number is 4*x

Then, four times a number is added to 12 the result is -28 can be written as:

4*x + 12 = -28

So, we can solve the equation for x by subtracting 12 from both sides:

4x + 12 - 12 = - 28 - 12

4x = -40

Then, dividing by 4 into both sides, we get:

So, the unknown number is equal to -10

To sketch the region of integration, we need the limits of integration for both x and y.

However, the given integral does not provide the limits or the function f(x, y), making it difficult to determine the region of integration accurately.

To change the order of integration, we will assume some limits and functions for illustration purposes. Let's consider the following assumptions:

∫250∫3x√0f(x,y)dydx

Assuming the limits of integration:

a = 0

b = 5

Assuming the functions:

g1(y) = 0

g2(y) = y²

The integral can be rewritten as:

∫0 to 5∫0 to y² f(x, y)dxdy

By changing the order of integration, we are integrating with respect to y first and then with respect to x.

The region of integration can be visualized as the area under the curve y = √x and above the x-axis, bounded by x = 0 and x = 5. When y varies from 0 to y², x varies from 0 to y.

Please note that these assumptions are made for illustrative purposes, as the original integral does not provide specific information regarding the limits of integration or the function f(x, y).

Answer:

the answer for the discount is A. P 82.50

Answer: The area of the region enclosed by the curves y=x, y=2x, x=y^2, x=4y^2 in the first quadrant is 119/5 square units.

Step-by-step explanation:

Let's begin by sketching the region in the first quadrant enclosed by the given curves:

We can see that the region is bounded by the lines y=x and y=2x, and the parabolas x=y^2 and x=4y^2.

To get the area of this region, we can use the change of variables u=y and v=x/y. This transformation maps the region onto the rectangle R={(u,v): 1 ≤ u ≤ 2, 1 ≤ v ≤ 4} in the uv-plane. To see why, note that when we make the substitution y=u and x=uv, the curves y=x and y=2x become the lines u=v and u=2v, respectively.

The curves x=y^2 and x=4y^2 become the lines v=u^2 and v=4u^2, respectively.Let's determine the Jacobian of the transformation. We have:

J = ∂(x,y) / ∂(u,v) =

| ∂x/∂u ∂x/∂v |

| ∂y/∂u ∂y/∂v |

We can compute the partial derivatives as follows:∂x/∂u = v

∂x/∂v = u

∂y/∂u = 1

∂y/∂v = 0

Therefore, J = |v u|, and |J| = |v u| = vu.

Now we can write the integral for the area of the region in terms of u and v as follows

:A = ∬[D] dA = ∫[1,2]∫[1,u^2] vu dv du + ∫[2,4]∫[1,4u^2] vu dv du

= ∫[1,2] (u^3 - u) du + ∫[2,4] 2u(u^3 - u) du

= [u^4/4 - u^2/2] from 1 to 2 + [u^5/5 - u^3/3] from 2 to 4

= (8/3 - 3/4) + (1024/15 - 32/3)

= 119/5.

Therefore, the area of the region enclosed by the curves y=x, y=2x, x=y^2, x=4y^2 in the first quadrant is 119/5 square units.

The surface area of the cuboid is 3.286 cm²

A cuboid is a solid shape or a three-dimensional shape.

Surface area is the amount of space covering the outside of a three-dimensional shape.

The surface area of a cuboid is expressed as;

SA = 2( lb + lh + bh)

length = 1 2/5 = 7/5

breadth = 5/8

height = 3/8

lb = 7/5 × 5/8 = 7/8

bh = 5/8 × 3/8 = 15/64

lh = 7/5 × 3/8 = 21/40

surface area =2( 7/8 + 15/64+21/40)

= 2( 0.875 + 0.234 + 0.525)
