Answer: The correct answer is b. (3x2y3 − 4x3y4)(3x2y3 + 4x3y4). This is because the given polynomial can be factored using the difference of squares formula, which states that a2 - b2 = (a + b)(a - b). In this case, a = 3x2y3 and b = 4x3y4. So, the given polynomial can be rewritten as (3x2y3)2 - (4x3y4)2 = (3x2y3 + 4x3y4)(3x2y3 - 4x3y4).

The (⍺3β3) oligomer of ATP synthase can have 3 different functional conformations.

The (⍺3β3) oligomer of ATP synthase, which consists of three α-subunits and three β-subunits, can exhibit three different functional conformations. These conformations are known as "open," "loose," and "tight" states. The binding change mechanism describes the sequential transition of the catalytic sites within ATP synthase as they alternate between these conformations, facilitating the synthesis of ATP.

The type of sampling that relies upon knowledge of the distribution or proportion of population characteristics in order to choose a sample that assures representativeness of these characteristics is called stratified sampling.

In stratified sampling, the population is divided into different subgroups or strata based on specific characteristics or variables. The proportion of each subgroup in the population is known, and a sample is then selected from each stratum. This ensures that the sample is representative of the population in terms of the specific characteristics being studied.

To perform stratified sampling, follow these steps:
1. Identify the relevant characteristics or variables that you want to study.
2. Divide the population into distinct strata based on these characteristics.
3. Determine the proportion or distribution of each stratum in the population.
4. Select a random sample from each stratum, ensuring that the sample size is proportional to the size of the stratum in the population.
5. Combine the samples from each stratum to create the overall representative sample.

In conclusion, stratified sampling is a type of sampling method that ensures representativeness of population characteristics by dividing the population into subgroups and selecting samples from each stratum based on their proportion in the population.

The hypotheses for the test are H₀: σ₁² = σ₂² and H₁: σ₁² ≠ σ₂². This is a two-tailed test to assess if there is a difference in the standard deviations of sound levels between the areas designated as "casualty doors" and operating theaters. The claim being investigated is whether or not there is a difference in the standard deviations.

The hypotheses for the test are:

H₀: σ₁² = σ₂² (There is no difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

H₁: σ₁² ≠ σ₂² (There is a difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

This hypothesis test is a two-tailed test because the alternative hypothesis is not specifying a direction of difference.

To substantiate the claim that there is a difference in the standard deviations, we will conduct a two-sample F-test at a significance level of 0.10, comparing the variances of the two groups.

Step-by-step explanation:

V = (3.14)(1.5)²(3/3)

= (3.14)2.25 = 7.1

The book is opened to pages 11 and 12.

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

So, the book is opened to pages 11 and 12.

Step-by-step explanation:

Remark: This is an arithmetic sequence. Rather than going up, it is going down. Still it is an arithmetic sequence.

Givens

a1 = 20

d = -5

Formula

tn = a1 + (n-1)*-5      Remove the brackets

tn = 20  - 5n + 5

tn = 25 - 5n

So just to confirm it works, let n = 4 (which makes t4 = 5 as is given).

t4 = 25 - 5*4

t4 = 25 - 20

t4 = 5  which is exactly what t4 is

So, Lana gave away 26.32% of he Pokemon cards  to her little brother.

To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.

In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:

(125 / 475) * 100 = 0.2632 * 100 = 26.32%.

Lana gave away 26.32% of her Pokemon cards to her little brother.

Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:

Percentage given away

= (Cards given away / Total cards) * 100

= (125 / 475) * 100

= 26.32%.

The opposite diagonal is 5.95m long, exact as previous diagonal in length which indicates that the table's diagonal length is the same throughout.

According to the Pythagorean Theorem, the square of the length of the hypotenuse in every right triangle equals the sum of the squares of the lengths of the two legs.

Let's denote the width as w = 4.1m and the length as l = 4.1m. Then, the diagonal length d can be found as:

d² = w² + l²

Substituting the given values, we get:

d² = (4.1m)² + (4.1m)²

d² = 16.81m² + 16.81m²

d² = 2(16.81m²)

d = sqrt(2(16.81m²))

d ≈ 5.95m

So, we have found that the diagonal length across the table is approximately 5.95m.

Now, to prove that the diagonal length is the same length, we can repeat this calculation, but using the other diagonal of the table.

Let's denote the width as w = 4.1m and the length as l = 4.1m. Then, the other diagonal length d' can be found as:

d'² = w² + l²

Substituting the given values, we get:

d'² = (4.1m)² + (4.1m)²

d'² = 16.81m² + 16.81m²

d'² = 2(16.81m²)

d' = sqrt(2(16.81m²))

d' ≈ 5.95m

As a result, we have established that the other diagonal is roughly 5.95m long, the same as the first diagonal. This demonstrates that the table's diagonal length is the same throughout.

Therefore, A is 67 degrees.

Given the right triangle ABC with C=90°, B = 23° and c = 3.5 ft, we need to find A to the nearest degree.Solution:Using the right triangle ABC, we can use the sine ratio since we know the opposite and hypotenuse side. So,sin A = (Opposite side) / (Hypotenuse side)sin A = a / c (where a is the opposite side)sin A = a / 3.5a = 3.5 sin AAgain using the angle sum property in a triangle, we know that the sum of all angles in a triangle is equal to 180 degrees.A + B + C = 180 degreesSince we know B and C, we can calculate A.A + 23 + 90 = 180A = 67 degrees.
