Matrics its determinant is det(A+B) = 4.

Hence, det(A+B) is not equal to det(A) + det(B) = 5.

It is not necessarily true that if A and B are n × n matrices with detA = 2 and detB = 3, then det(A+B) = 5.

The determinant of a matrix is a scalar value that encodes various properties of the matrix.

It has the property that det(kA) = kⁿ × det(A) for any scalar k and n × n matrix A, n denotes the dimension of the matrix.

The determinant does not satisfy the distributive property, that is, det(A+B) is not necessarily equal to det(A) + det(B).

To illustrate this point, consider the following counter example.

Let A be the matrix:

[ 2 0 ]

[ 0 1 ]

and let B be the matrix:

[ -1 0 ]

[ 0 3 ]

Then detA = 2 and detB = 3.

The sum A + B is the matrix:

[ 1 0 ]

[ 0 4 ]

and

In general, cannot conclude that det(A+B) = 5 given that detA = 2 and detB = 3.

Answer:

See below.

Step-by-step explanation:

A = (-2/3, 0)

B = (-1/6, 0)

C = (1/2, 0)

D = (4/3, 0)

Step-by-step explanation:

the interval between 0 and 1 shows us, that on that scale the distance between 2 full numbers is split into 6 parts.

so, every little marker represents 1/6.

A goes 4 markers below 0 (left of 0) and is -4/6 = -2/3.

B goes 1 marker below 0 and is -1/6.

C goes 3 markers above 0 (right of 0) and is 3/6 = 1/2.

D goes 2 markers above 1 and is

1 + 2/6 = 6/6 + 2/6 = 8/6 = 4/3 = 1 1/3

please pick the format your teacher wants you to use to write the result.

if you actually need decimals instead of fractions :

-2/3 = -0.666666666...

-1/6 = -0.166666666...

1/2 = 0.5

Using the Poisson paradigm, the probability that all 10 missiles are hit is approximately 0.0000001016.

To inexact the likelihood that every one of the 10 rockets are hit, we can utilize the Poisson worldview. When events are rare and independent, the Poisson distribution is frequently used to model the number of events occurring in a fixed time or space.

We can think of each missile strike as an independent event in this scenario, with a 0.1 chance of succeeding (hitting the target). We should characterize X as the quantity of hits among the 10 rockets.

Since the likelihood of hitting a rocket is 0.1, the likelihood of not hitting a rocket is 0.9. Thusly, the likelihood of every one of the 10 rockets being hit can be determined as:

P(X = 10) = (0.1)10  0.00000001 This probability is extremely low, and directly calculating it may require a lot of computing power. However, the Poisson distribution enables us to approximate this probability in accordance with the Poisson paradigm.

The average number of events in a given interval in the Poisson distribution is  (lambda). For our situation, λ would be the normal number of hits among the 10 rockets.

The probability of having all ten missiles hit can be approximated using the Poisson distribution as follows: = (number of trials) * (probability of success) = 10 * 0.1 = 1.

P(X = 10) ≈ e^(-λ) * (λ^10) / 10!

where e is the numerical steady around equivalent to 2.71828 and 10! is the ten-factor factorial.

P(X = 10) ≈ e^(-1) * (1^10) / 10!

P(X = 10) = 0.367879 * 1 / (3628800) P(X = 10) = 0.0000001016 According to the Poisson model, the likelihood of hitting all ten missiles is about 0.0000001016.

Answer: 22.5°

Step-by-step explanation:

Complementary angles are the angles that when we add them together, they're equal to 90°.

Let the smaller angle be represented by x.

Then, the larger one will be 3 × x = 3x

We then add both angles together and equate them to 90°. Therefore,

x + 3x = 90°

4x = 90°

x = 90/4

x = 22.5°

The smaller angle is 22.5°

To find the amount of 50% disinfectant solution that must be mixed with a 40% disinfectant solution to produce 35 gallons of a 44% disinfectant solution,

we can use the following formula: Amount of 50% solution + Amount of 40% solution = Total amount of mixture Let x be the amount of 50% disinfectant solution to be mixed with a 40% disinfectant solution.

Then, the amount of 40% disinfectant solution will be 35 - x (since the total amount of mixture is 35 gallons).

Using the concentration formula: Concentration of mixture = (Amount of solute / Total amount of mixture) * 100,

we can write:0.44 = (0.5x + 0.4(35 - x)) / 35Multiplying both sides by 35

gives:15.4 = 0.5x + 14 - 0.4x

Simplifying the equation:0.1x = 1.4x = 14

Therefore, 14 gallons of the 50% disinfectant solution must be mixed with 21 gallons of the 40% disinfectant solution to produce 35 gallons of a 44% disinfectant solution.

Solving the equation (6x)(9x) using the zero product property we get the solution is x = 2.

To find the solution to the equation, we can use the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero. In this case, the product of (6x) and (9x) is given as 88 square feet. So, we have the equation (6x)(9x) = 88.

To solve this equation, we can first simplify it by multiplying the terms inside the parentheses. (6x)(9x) becomes 54x^2. Now our equation is 54x^2 = 88.

To isolate x, we divide both sides of the equation by 54. This gives us x^2 = 88/54. Simplifying further, we have x^2 = 22/27.

Taking the square root of both sides of the equation, we get x=±√(22/27). However, since the length and width of the rectangular patio are increased, we are only interested in the positive value of x.

Approximating the value of √(22/27), we find that x ≈ 0.832. This value represents the amount by which both the length and width of the patio should be increased to obtain an area of 88 square feet.

The value of ∠WXY = 20.

What is Exterior angle theorem?

The exterior angle theorem describes the connection between the two remote angles in a triangle and the external angle created by an extended side outside the triangle.

Given: Measure of angle YWX = (3x + 17) °

Measure of angle WXY = (3x + 2) °

Measure of angle XYZ = (10x − 5) °

Therefore, m∠XYZ = m∠YWX + m∠WXY (exterior angle theorem)

⇒ (10x − 5) ° = (3x + 17) ° + (3x + 2) °

Solve for x,

⇒ 10x - 5 = 3x + 17 + 3x + 2

⇒ 10x - 6x = 17 + 7

⇒ 4x = 24

⇒ x = 6

∴ ∠WXY = (3x + 2) = 18 + 2 = 20

Natural selection and genetics are intrinsically linked as they both play crucial roles in the process of evolution.

Natural selection is the mechanism by which certain heritable traits become more or less common in a population over generations. It acts on the genetic variation present within a population, favoring individuals with advantageous traits that increase their fitness and survival. These advantageous traits are often the result of genetic variations or mutations that confer a selective advantage. Genetics, on the other hand, is the study of heredity and the variation of genes within populations. Genes are segments of DNA that contain the instructions for the development and functioning of organisms. Genetic variations arise through processes such as mutation, recombination, and gene flow.

Natural selection acts upon the genetic variation present in a population. Individuals with beneficial genetic variations are more likely to survive, reproduce, and pass on their genes to the next generation, increasing the frequency of those favorable traits within the population. Over time, this leads to the accumulation of adaptations and the evolution of populations. Genetics provides the foundation for understanding the inheritance of traits and the mechanisms by which genetic variations arise and are transmitted from one generation to the next. It helps explain how variations within genes can result in phenotypic differences and how these variations can be subject to selective pressures in natural environments.

Overall, genetics provides the raw material for natural selection to act upon, and natural selection, in turn, shapes the genetic composition of populations over time. The interplay between natural selection and genetics is fundamental to our understanding of how species evolve and adapt to changing environments.
