Within the Uterus, a thick lining develops

Answer:

The answer is - 91

Step-by-step explanation:

f(x)=2x+1

g(x)=-5x+2

To find f(g(3)) first find f(g(x))

To find f(g(x)) multiply f(x) by g(x)

that's

f(g(x)) = (2x + 1)( - 5x + 2)

f(g(x)) = - 10x² + 4x - 5x + 2

f(g(x)) = - 10x² - x + 2

To find f(g(x)) when x = 3 substitute 3 into

f(g(x))

That's

f(g(3)) = -10(3)² - 3 + 2

f(g(3)) = -90 - 3 + 2

We have the final answer as

The required linear model is y = 5800 + 324x.

What is a linear equation?

Equations whose variables have a power of one are called linear equations.

Given, a bakery sells 5800 muffins in 2010

the bakery sells 7420 muffins in 2015

So, the number of muffins sold after 2010 through 2015:

7,420 - 5,800 = 1,620

Then, the sales per year:

1,620 muffins sold since 2010 / 5 years = 324 muffins per year.

Then our linear model will be:

y = 5800 + 324x

Hence, the required linear model is y = 5800 + 324x.

Step-by-step explanation:

Andy should write $507.18 for the balance on January 30. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

Four fundamental mathematical operations can be used to express any real number.

1. To determine the total of the numbers, use the addition operator ('+').

2. Use the sign "-" when subtracting to find the differences between the numbers.

3. Multiply when the result is the product of the numbers.

4. Dividing the numbers produces their quotient.

We are given that the amount balance on January 24 is $104.47 and she deposited $407.71 on January 30.

So, the amount Andy should write for the balance on January 30 is

⇒$104.47 + $407.71

⇒$507.18

Hence, Andy should write $507.18 for the balance on January 30.

Using the Bayes' theorem, we find the probability that the transferred ball was white given that the second ball drawn was white to be 52/89, or approximately 0.5843.

To solve this problem, we can use Bayes' theorem, which relates the conditional probability of an event A given an event B to the conditional probability of event B given event A:

P(A|B) = P(B|A) * P(A) / P(B)

where P(A|B) is the probability of event A given that event B has occurred, P(B|A) is the probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.

In this problem, we want to find the probability that the transferred ball was white (event A) given that the second ball drawn was white (event B). We can calculate this probability as follows:

P(A|B) = P(B|A) * P(A) / P(B)

P(B|A) is the probability of drawing a white ball from urn b given that the transferred ball was white and is now in urn b. Since there are now six white balls and three black balls in urn b, the probability of drawing a white ball is 6/9 = 2/3.

P(A) is the prior probability of the transferred ball being white, which is the number of white balls in urn a divided by the total number of balls in urn a, or 6/13.

P(B) is the prior probability of drawing a white ball from urn b, which can be calculated using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

where P(B|not A) is the probability of drawing a white ball from urn b given that the transferred ball was black and P(not A) is the probability that the transferred ball was black, which is 7/13.

To calculate P(B|not A), we need to first calculate the probability of the transferred ball being black and then the probability of drawing a white ball from urn b given that the transferred ball was black.

The probability of the transferred ball being black is 7/13. Once the transferred ball is moved to urn b, there are now five white balls and four black balls in urn b, so the probability of drawing a white ball from urn b given that the transferred ball was black is 5/9.

Therefore, we can calculate P(B) as follows:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= (2/3) * (6/13) + (5/9) * (7/13)

= 89/117

Now we can plug in all the values into Bayes' theorem to find P(A|B):

P(A|B) = P(B|A) * P(A) / P(B)

= (2/3) * (6/13) / (89/117)

= 52/89

Therefore, the probability that the transferred ball was white given that the second ball drawn was white is 52/89, or approximately 0.5843.

True. Regression analysis involves analyzing the relationship between two variables, typically by using all available data points.

Ignoring certain data points, such as the highest and lowest volume data points, can skew the results and lead to inaccurate conclusions. Therefore, it is important to use all available data points in regression analysis to ensure that the relationship between the variables is accurately represented.

True: Regression analysis uses all data points, not just the highest and lowest volume data points. It is a statistical method for analyzing the relationship between a dependent variable and one or more independent variables. By including all data points, regression analysis can identify patterns and trends, providing a more accurate representation of the data. This allows for better predictions and insights into the relationships between variables. Excluding some data points, such as only using the highest and lowest volume data points, would limit the analysis and potentially lead to inaccurate results.

The volume of the solid enclosed by the given surface and plane is \(V = [(1/2)(1+x^2ye^y)^2 + (1/6)x^2ye^y (1+x^2ye^y)^3] |[-1,1]\) cubic units.

To find the volume of the solid enclosed by the given surfaces, we can set up a triple integral over the region bounded by the planes y = 0, y = 1, x = -1, and x = 1.

The integral for the volume is given by:

\(V = ∫∫∫ R (1 + x^2ye^y) dV\)

Where R is the region bounded by the planes.

To evaluate this integral, we need to set up the limits of integration for x, y, and z.

The limits for z are from z = 0 to

\(z = 1 + x^2ye^y\)

.The limits for y are from y = 0 to y = 1.

The limits for x are from x = -1 to x = 1.

Therefore, the volume V can be calculated as:

\(V = ∫∫∫ R (1 + x^2ye^y) dV = ∫[-1,1] ∫[0,1] ∫[0,1+x^2ye^y] (1 + x^2ye^y) dz dy dx\)

Now, we can integrate with respect to z first:

\(V = ∫[-1,1] ∫[0,1] [z + (1/2)x^2ye^y z^2] |[0,1+x^2ye^y] dy dx= ∫[-1,1] ∫[0,1] [(1+x^2ye^y) + (1/2)x^2ye^y (1+x^2ye^y)^2] dy dx\)Next, we integrate with respect to y:

\(V = ∫[-1,1] [(1/2)(1+x^2ye^y)^2 + (1/6)x^2ye^y (1+x^2ye^y)^3] |[0,1] dx\)

Finally, we integrate with respect to x:

\(V = [(1/2)(1+x^2ye^y)^2 + (1/6)x^2ye^y (1+x^2ye^y)^3] |[-1,1]\)

Therefore, required volume is \(V = [(1/2)(1+x^2ye^y)^2 + (1/6)x^2ye^y (1+x^2ye^y)^3] |[-1,1]\)

The angular momentum of the stuck-together particles with respect to the origin is (-3.09 î + 5.95 ĵ) kg*m²/s, in unit-vector notation.

To find the angular momentum of the stuck-together particles with respect to the origin after the collision, we need to first find the final velocity of the combined particles. Since the collision is completely inelastic, the two particles will stick together and move as one unit. We can use the conservation of momentum to find the final velocity:

(m₁v₁ + m₂v₂) / (m₁ + m₂) = v₀

where m₁ and v₁ are the mass and velocity of the first particle, m₂ and v are the mass and velocity of the second particle, and v₀ is the final velocity of the combined particles.

Plugging in the given values, we get:

(3.08 kg)(-1.43 m/s) + (3.16 kg)(8.93 m/s) / (3.08 kg + 3.16 kg) = 3.49 m/s

So the final velocity of the combined particles is 3.49 m/s.

Now, to find the angular momentum with respect to the origin, we need to use the cross product of the position vector and the linear momentum vector:

L = r x p

where r is the position vector from the origin to the center of mass of the combined particles, and p is the linear momentum vector of the combined particles.

The position vector can be found using the given xy coordinates:

r = (-0.291 m)î + (-0.152 m)ĵ

The linear momentum vector can be found using the combined mass and velocity:

p = (m1 + m2)vf = (3.08 kg + 3.16 kg)(3.49 m/s) = 21.42 kg*m/s

So the angular momentum can be calculated as:

L = (-0.152 m)(21.42 kgm/s)î - (-0.291 m)(21.42 kgm/s)ĵ

= -3.09 î + 5.95 ĵ kg*m²/s

The volume of a rectangular prism is always greater than or equal to the volume of a pyramid with the same height and base.

How to find the volume of a rectangular prism and pyramid?

The formula for the volume of a rectangular prism is:

Volume = Length * Width * Height

The formula for the volume of a pyramid is:

Volume = (Base Area * Height) / 3

The volume of a rectangular prism is always greater than or equal to the volume of a pyramid with the same height and base.

This is because the volume of a rectangular prism is calculated by multiplying its three dimensions together, whereas the volume of a pyramid is calculated by multiplying the base area by the height and dividing the result by 3.

Hence, the volume of the rectangular prism is greater than the volume of the pyramid with the same height and base. This is because the rectangular prism has additional volume in the form of its width, which the pyramid does not have.
