The intersection of events A and B is the event of exactly two tails. This is because event A is defined as exactly two tails and event B is defined as at least two tails.

Since two tails is both exactly two tails and at least two tails, the intersection of the two events is exactly two tails.

The intersection of two sets is the set of all elements that are common to both sets. This is also known as the intersection of two conjunctions. To find the intersection of two sets, you take the elements from both sets and keep only the elements that are found in both sets. For example, given the sets A = {1, 2, 3} and B = {2, 3, 4}, the intersection of A and B would be {2, 3}.

Answer: The Fourth One

Step-by-step explanation:

Answer:

Bottom right corner

Step-by-step explanation:

one-sided limits of a function f(x) at x = 1 is  lim x → 2[f(x) - f(2)]/(x - 2) = 20

Since  function f(x) = 5(x² - 1) and we want to find its derivative, we can proceed thus.

Let x = h + 2

So,  

f(x) = 5(x² - 1)

f(2) = 5[(2)² - 1]

= 5[4 - 1]

= 5(3)

= 15

f(2 + h) = 5[(2 + h)² - 1)

= 5(4 + 4h + h² - 1)

= 5(3 + 4h + h²)

= 15 + 20h + 5h²

So, f(2 + h) - f(2) = 15 + 20h + 5h² - 15

= 20h + 5h²

So, we have that

[f(2 + h) - f(2)]/h = (20h + 5h²)/h

= 20 + 5h

Now, taking the limit as h → 0, we have

= 20 + 5(0)

= 20 + 0

= 20

So,  lim h → 0[f(2 + h) - f(x)]/h = lim x → 2[f(x) - f(2)]/(x - 2) = 20

So,  lim x → 2[f(x) - f(2)]/(x - 2) = 20

The equation of the line that passes through two points (1, 4) and (3, 10) is,

y = 3x + 1.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

A line passes through two points (1, 4) and (3, 10).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

y - 4 = 6/2 (x - 1)

The selling price for the jacket is $36.

To determine the selling price of the jacket, we need to calculate the markup percentage on the original price of $20. A markup percentage is the increase in price over the original cost. In this case, the markup percentage is 80%, which means the selling price is $20 + ($20 * 0.8) = $20 + $16 = $36.

Here is the breakdown of the calculation:

Original cost of the jacket: $20

Markup percentage: 80%

Markup amount: $20 * 0.8 = $16

Selling price: $20 + $16 = $36

The Venn diagram for this situation is as follows:

The probability that both quartz and tourmaline will be found, but not aquamarine is P(A intersection B) = P(A)*P(B) = 0.80 * 0.36 = 0.29.

The probability that quartz will be found, but not tourmaline or aquamarine is P(A) – P(A intersection B) – P(A intersection C) = 0.80 - 0.29 - 0.24 = 0.27.

The probability that none of these types of specimens will be found is 1 – P(A) – P(B) – P(C) + P(A intersection B) + P(A intersection C) + P(B intersection C) = 1 - 0.80 - 0.36 - 0.28 + 0.29 + 0.24 + 0.16 = 0.17.

The amount of RNA transcribed from promoter gene, which can consequently influence the amount of protein made from this gene. So the option c is correct.

A gene's DNA sequence is duplicated during transcription in order to create an RNA molecule.

The primary transcribed enzyme is called RNA polymerase.

RNA polymerase connects to a promoter sequence close to the start of a gene to start transcription (directly or through helper proteins).

A new, complementary RNA molecule is created by RNA polymerase using a template from one of the DNA strands (the template strand).

Termination is the procedure that brings transcription to a conclusion. The RNA sequences that indicate that the transcript is done are what determine when a process is terminated.

It takes the runner distance 15.625 seconds to get to the flagpole because 125m/8m/s equals 15.625s.

1. Determine the distance: 125 metres

2. Determine the velocity: 8 m/s

3. Calculate the time as follows: 125 m/ 8 m/s = 15.625 s

We must know the distance the runner must cover and their pace in order to determine how long it will take them to get to the flagpole. This time, the runner begins 125 metres west of the flagpole and moves east at a speed of 8.0 metres per second. The formula distance (in meters)/speed (in metres per second) = time can be used to determine how long it takes the runner to get to the flagpole (in s).  Given that the speed is 8 m/s and the distance is 125 m, the calculation is 125 m/ 8 m/s = 15.625 s. It follows that the runner needs 15.625 seconds to get to the flagpole. This formula can be used to determine how long it will take any object to go a specific distance at a specific speed. It is crucial to remember that in order to obtain the duration in s, the speed must be expressed in m/s and the distance must be expressed in m.

Her bi-weekly gross earnings if she works 47 hours during a week of her pay period is $4110.525.

The answer is determined by calculating the income earned for the additional hours she works multiplied by the income earned for the additional hours. This is then added with the gross income for the week and the total is calculated by taking the sum of the two.

Given that her bi-weekly gross earnings are $913.45, and she earns additional compensation for all hours over 40 worked in one week.

For 47 hours, the extra hours worked are 7.

Hence, the compensation for additional hour is:

a = 7 (913.45/2)

a = 3197.075

The gross income would be:

Total = bi-weekly pay + additional hours

T = 913.45 + 3197.075

T = 4110.525

Hence, her bi-weekly gross earnings if she works 47 hours during a week of her pay period is $4110.525.

Matrix A belongs to the permutation and Markov classes.

This is the case for matrix A, as it has one 1 in each row and column and 0s everywhere else. Matrix A is also a Markov matrix, which means that all the entries are non-negative and the sum of each row is equal to 1. This can be seen by summing each row, which yields 1+0+0 = 1, 0+1+0 = 1, and 1+0+0 = 1.

Matrix B belongs to the orthogonal, projection, and diagonalizable classes. Matrix B is orthogonal, which means that it is a square matrix whose columns and rows are orthonormal unit vectors (i.e. the dot product of any two columns or rows is 0). This is the case for matrix B, as the dot product of any two columns or rows yields 0. Matrix B is also a projection matrix, which means that it is a square matrix whose columns are all of unit length (i.e. the dot product of any two columns or rows is 1). This can be seen by taking the dot product of any two columns or rows, which yields 1. Finally, matrix B is diagonalizable, which means that it can be transformed into a diagonal matrix using a similarity transformation. This can be seen by calculating the eigenvalues and eigenvectors of matrix B, which yields the same diagonal matrix.
