Place the steps of eukaryotic DNA replication in order, from when a germ cell enters gap 1 (G_1) phase to the cell cycle termination.

Answers

Answer 1

Answer:

The correct order of the steps of eukaryotic DNA replication from when a germ cell enters gap 1 (G1) phase to the cell cycle termination is : G1-> S Phase ->G2 ->Mitosis ->Cytokinesis ->Cell cycle termination

Step-by-step explanation:

The correct order of the steps of eukaryotic DNA replication from when a germ cell enters gap 1 (G1) phase to the cell cycle termination is as follows:

Step 1: G1 phase - During this phase, the germ cell is growing and preparing for DNA synthesis.

Step 2: S phase - DNA replication occurs during this phase. The chromosomes duplicate to form two identical chromatids, which remain attached at the centromere.

Step 3: G2 phase - During this phase, the cell checks for any errors in DNA replication and prepares for cell division.

Step 4: Mitosis - The cell divides its replicated DNA and organelles into two identical daughter cells. This process ensures that each daughter cell has the same amount of genetic material as the parent cell.

Step 5: Cytokinesis - The cytoplasm divides, creating two identical daughter cells.

Step 6: Cell cycle termination: After successful completion of mitosis and cytokinesis, the cell cycle is terminated, and the daughter cells may enter a new cycle or enter a non-dividing state (G0 phase).

Write the compound inequality that represents the statement. The quotient of a number y and 3, less 2 is between –7 and 4.

Solve the compound inequality.

Answers

The compound inequality is -7 < y/3 - 2 < 4 and the solution is -15 < y < 18

identifying and solving the compound inequality

To write the compound inequality that represents the statement, we can first translate the words into symbols:

The quotient of a number y and 3, less 2: y/3 - 2

Is between -7 and 4: -7 < y/3 - 2 < 4

So the compound inequality that represents the statement is:

-7 < y/3 - 2 < 4

To solve this compound inequality, we can first add 2 to all parts of the inequality:

-7 + 2 < y/3 - 2 + 2 < 4 + 2

Simplifying, we get:

-5 < y/3 < 6

To isolate y/3, we can multiply all parts of the inequality by 3:

-15 < y < 18

Answers

The probability that Emme answers exactly 3 questions correctly is 0.1961.

Since each question has four answer choices and only one is correct, the probability of Emme randomly guessing the correct answer for each question is 1/4 = 0.25. Emme needs to answer exactly 3 out of the 9 questions correctly, so we use the binomial distribution with n = 9 and p = 0.25 to calculate the probability:

P(X = 3) = (9 choose 3) * (0.25)^3 * (0.75)^6

Using a calculator, we get:

P(X = 3) = 0.1961

Therefore, the probability that Emme answers exactly 3 questions correctly is 0.1961.

the probability is approximately 0.6 that in a randomly selected week, they will make a combined total less than what amount?

Answers

There is a probability of around 60% that during a week picked randomly, the combined sum of their earnings will be below $0.2533.

The given probability is a measure of the chances that the occurrence of an event will happen. In the context of the question, we want to calculate the combined total of earnings that are less than a certain amount. We know that the probability is approximately 0.6. Therefore, the answer is given by the value that satisfies this condition.

That is, P(X < a) = 0.6where X represents the combined total earnings of a randomly selected week, and a is the required amount.

To solve for a, we can use the cumulative distribution function (CDF) of X. The CDF gives the probability that X is less than or equal to a. Therefore, CDF(a) = P(X ≤ a)

The complement of this probability isP(X > a) = 1 - CDF(a)

We know that P(X < a) = 0.6, which is equivalent to (X ≤ a) = P(X < a) + P(X = a) = 0.6 + 0 = 0.6

Therefore, P(X > a) = 1 - CDF(a) = 1 - P(X ≤ a) = 1 - 0.6 = 0.4

Now we can use a calculator to find the value of a that corresponds to P(X > a) = 0.4.

For example, if we use a calculator, we get a value of a = 0.2533 (rounded to four decimal places).

Therefore, the probability is approximately 0.6 that in a randomly selected week, they will make a combined total of less than $0.2533.

abc is a right triangle with points a 2,5 b 2,0 and c x,0. if the area of abc is 25 square units, what us the equation of ac?

Answers

As the given abc is a right triangle with points a(2, 5), b(2, 0), and c(x, 0). The area of 'abc' is 25 square units. and the equation of AC is x = 5√5.

The equation of ac has to be found. Since triangle ABC is right-angled, it can be shown that

                  AC² = AB² + BC²

    Finding the lengths of AB and BC before using the Pythagorean theorem to find AC.

    Using the distance formula,

                     AB =√(5²+0²)

                           = √25

                          = 5,

           And BC = √(x²+0²)

                         = √x²

                          = x.

     

  Area of a right triangle = ½(base × height)

          Here base = AB and height = BC,

              So,  ½ × 5 × x = 25

                            ⇒ 5x = 50

                              ⇒ x = 10

       Now, to find AC, use the Pythagorean Theorem.

                      AC² = AB² + BC²

                             = 5² + 10²

                             = 25 + 100

                             = 125AC

                             = √125

                             = 5√5

     Thus, the equation of AC is x = 5√5. Answer: x = 5√5.

the cpa practice advisor reports that the mean preparation fee for federal income tax returns was . use this price as the population mean and assume the population standard deviation of preparation fees is .

Answers

The CPA Practice Advisor reports that the mean preparation fee for federal income tax returns was 261. Use this price as the population mean and assume the population standard deviation of preparation fees is 120.

We need to find the probability of selecting a random sample of 20 tax returns and a standard deviation of the sample preparation fees of 50 or less.

We use the central limit theorem that states that, regardless of the shape of the population, the sampling distribution of the sample means approaches a normal distribution with mean μ and standard deviation

σ/√n

where μ is the population mean, σ is the population standard deviation, and n is the sample size.

Therefore, we have:

[tex]\mu = 261\]\\sigma = $120\]\\n = 20\][/tex]

[tex]S.E.= \frac{\sigma}{\sqrt{n}}\\S.E =\frac{\ 120}{\sqrt{20}}\\S.E =26.83[/tex]

The probability of selecting a random sample of 20 tax returns and a standard deviation of the sample preparation fees of 50 or less is given by:

[tex]P(Z < \frac{X - \mu}{S.E})\][/tex]

where X is the sample mean, μ is the population mean, and S.E is the standard error of the mean.

To calculate the probability, we standardize the distribution of the sample means using the z-score formula, i.e.,

[tex]\[z = \frac{X - \mu}{S.E} = \frac{\50 - \261}{\26.83} = -7.91\][/tex]

Therefore, the probability of selecting a random sample of 20 tax returns and a standard deviation of the sample preparation fees of 50 or less is zero because the z-score is less than the minimum z-score (i.e., -3.89) that corresponds to the probability of selecting a random sample of 20 tax returns and a standard deviation of the sample preparation fees of 50 or less.

Thus, it is impossible to obtain such a sample.

From past experience, Hudson noticed that he will get about $13 in tips for each table he waits on. How much would Hudson expect to earn in a day on which he waits on 18 tables? How much would Hudson expect to make in a day when waiting on t tables?

Answers

The total amount of money earned by Hudson in a day on which he waits on 18 tables is $264.

The total amount of money earned by Hudson in a day on which he waits on t tables is $(30 + 13t).

How to determine Hudson's earnings in a day on which he waits on 18 tables?

Based on the information provided above, we can logically deduce that a linear equation that models the total amount of money earned by Hudson at this restaurant is represented by the following function:

y = 30 + 13t

Where:

t represent the number of tables he waits on that day.y represent the total earnings.

When the number of tables he waits on that day is equal to 18, Hudson's total earnings can be calculated as follows;

y = 30 + 13t

y = 30 + 13(18)

y = $264.

When the number of tables he waits on that day is t tables, Hudson's total earnings can be calculated as follows;

y = 30 + 13t = $(30 + 13t).

What is scaler factor?

Scale factor is a numerical ratio that describes how much a geometric figure has been enlarged or reduced. It is the ratio of the length of a side, diagonal, or any other linear dimension of the new (dilated) figure to the corresponding dimension of the original figure.

The distance between two points can be calculated using the distance formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$.[/tex]

To determine the scale factor, we need to compare the distances between corresponding points in the original and dilated polygons. Let's start by finding the distance between points A and B in the original polygon:

[tex]$d_{AB}=\sqrt{(3-1)^2+(-1+1)^2}=\sqrt{4}=2$[/tex]

Now let's find the distance between corresponding points A' and B' in the dilated polygon:

[tex]$d_{A'B'}=\sqrt{(12-4)^2+(-4+4)^2}=\sqrt{64}=8$[/tex]

To find the scale factor, we divide the corresponding distances:

[tex]$scale\ factor=\frac{d_{A'B'}}{d_{AB}}=\frac{8}{2}=4$[/tex]

After Jeff gave 20 of his stickers to Dan, Dan had 40% fewer stickers than Jeff (had after he gave away 20 of his stickers).

How many stickers did Dan have at first?

The total number of stickers that Jeff had is denoted by J, and the total number of stickers that Dan had is denoted by D.

In order to solve the question, let us first represent the given data mathematically:

J = 1.5D; D+20 = 0.6(J-20)

We have 2 equations and 2 unknowns, J and D.

We can solve these equations using simultaneous linear equations.

Substitute the first equation in the second equation:

D+20=0.6(J-20)

⇒ D+20=0.6J-12

⇒ D=0.6J-32

Now substitute the value of D in the first equation:

J=1.5D

⇒ J=1.5(0.6J-32)

⇒ J=0.9J-48.

Therefore, J=480

The total number of stickers that Jeff had initially was 480.

Now, to calculate the total number of stickers that Dan had, we can use the equation

J=1.5D:J=1.5D

Yes, the quadrilateral is a parallelogram. To prove this using the distance formula method, we need to show that opposite sides of the quadrilateral are equal in length.

We can calculate the distance between each pair of points using the distance formula:

d = [tex]\sqrt{((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

Using this formula, we get:

d(LM) = √[tex]((5 - (-1))^2 + (8 - 6)^2)[/tex] = √(36 + 4) = √(40) = 2√(10)

d(NP) = √[tex]((-8 - 0)^2 + (12 - 2)^2)[/tex] = √(64 + 100) = √(164) = 2√(41)

d(LN) = √[tex]((0 - (-1))^2 + (2 - 6)^2)[/tex] = √(1 + 16) = √(17)

d(MP) = √[tex]((-8 - 5)^2 + (12 - 8)^2[/tex]) = √(169 + 16) = √(185)

We can see that d(LM) = d(NP) and d(LN) = d(MP), which means that opposite sides of the quadrilateral are equal in length. Therefore, the quadrilateral is a parallelogram.

If sin (x) =3 cos(x), then what is sin(x) times cos (x)?

Answers

Using the identity that sin^2(x) + cos^2(x) = 1, we can rewrite sin(x) in terms of cos(x):

sin^2(x) + cos^2(x) = 1
Dividing both sides by cos^2(x):

tan^2(x) + 1 = sec^2(x)
Substituting sin(x) = 3cos(x) into the left-hand side:

tan^2(x) + 1 = (1/9)sec^2(x)
Multiplying both sides by cos^2(x):

(sin(x)/cos(x))^2 + cos^2(x) = (1/9)(1/cos^2(x))
Expanding the left-hand side:

sin^2(x)/cos^2(x) + cos^2(x) = 1/9cos^2(x)
Rearranging and factoring out cos^2(x):

sin^2(x) = (1/8)cos^4(x)
Multiplying both sides by cos(x):

sin^2(x)cos(x) = (1/8)cos^5(x)
Using the identity sin(x)cos(x) = (1/2)sin(2x):

(1/2)sin(2x) = (1/8)cos^5(x)
Multiplying both sides by cos(x):

(1/2)sin(2x)cos(x) = (1/8)cos^6(x)
Using the identity sin(2x) = 2sin(x)cos(x):

sin(x)cos(x) = (1/16)cos^6(x)
Therefore, sin(x)cos(x) is equal to (1/16)cos^6(x).

a pair of headphones originally costs 95$ and is on sale for 70$ what is the percent change in the price of the headphones? be sure to show whether it is a percent increase or decrease.

Answers

The percent decrease in the price of the headphones is 26.32%.


Explanation:

To find the percent change in price, we can use the following formula:

percent change = (new value - old value) / old value * 100%

     
In this case, the old value is the original price of the headphones, which is $95.
   

The new value is the sale price, which is $70. Plugging these values into the formula, we get:percent change = (70 - 95) / 95 * 100%

   

percent change = -25 / 95 * 100%

     

percent change = -0.2632 * 100%

   

percent change = -26.32%

   
The negative sign indicates that the price has decreased, and the magnitude of the percent change is 26.32%, which means that the sale price is 26.32% lower than the original price.

A fish tank, in a shape of rectangular prism, measures
100 cm × 60 cm X40 cm. The water level reached the blvoo eveD gror vIs midpoint of the base (the 50 cm mark), when the tank was tilted to rest on a 60 cm edge, as shown in the
100
diagram on the right. What would be the depth of the water, if the tank is returned to its horizontal position (resting on its 60 cm × 100 cm base)?

Answers

When the tank is tilted, the water level reaches the midpoint of the 60 cm side, which is 30 cm from the bottom of the tank. This means that the height of the water is 30 cm.

To find the depth of the water when the tank is returned to its horizontal position, we need to use the concept of similar triangles. The two triangles formed by the water level and the sides of the tank are similar, because they have the same angles.

Let x be the depth of the water in centimeters when the tank is returned to its horizontal position. Then we have:

(40 - x) / 60 = 30 / 50

Simplifying this equation, we get:

40 - x = 36

x = 4

Therefore, the depth of the water in the fish tank when it is returned to its horizontal position is 4 cm.

miguel went to a movie theater and bought a large bag of popcorn that cost $10.49. to avoid spending too much money in all, he determined that he could spend up to $5.51 on a drink. let x represent how much money miguel wanted to spend in all. which inequality describes the problem?

Answers

The inequality that represents Miguel's spending limit is $16.00 ≤ x.

Let x represent the total amount of money Miguel wants to spend. We know he spent $10.49 on popcorn and can spend up to $5.51 on a drink.

To find the inequality, we can add these two amounts together and set it less than or equal to x, since x represents the maximum amount he wants to spend. Mathematically, we can write:

$10.49 + $5.51 ≤ x

Simplifying this inequality, we get:

$16.00 ≤ x

This means that Miguel can spend up to $16.00 in total on the popcorn and drink combined. If he spends more than $16.00, he will have exceeded his limit.

given that kw for water is 2.4×10−14 at 37 ∘c, calculate the ph of a neutral aqueous solution at 37 ∘c, which is the normal human body temperature.

Answers

6.81 is the Ph of a neutral aqueous solution.

To calculate the pH of a neutral aqueous solution at 37°C with a KW of 2.4×10⁻¹⁴, follow these steps:

1. Identify that in a neutral aqueous solution, the concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻) are equal. Therefore, [H⁺] = [OH⁻].

2. Use the KW expression, which is the product of [H⁺] and [OH⁻] concentrations. In this case, KW = 2.4×10⁻¹⁴.

3. Since [H⁺] = [OH⁻], you can rewrite the KW expression as KW = [H⁺]². Now, solve for [H⁺] by taking the square root of KW: [H⁺] = sqrt(KW) = sqrt(2.4×10⁻¹⁴).

4. Calculate the square root: [H⁺] ≈ 1.55×10⁻⁷ M.

5. Use the pH formula: pH = -log[H⁺]. Plug in the [H⁺] value: pH = -log(1.55×10⁻⁷).

6. Calculate the pH: pH ≈ 6.81.

The pH of a neutral aqueous solution at 37°C with a KW of 2.4×10⁻¹⁴ is approximately 6.81.
