Answer:
600 atoms
Explanation:
Molecules are formed when two atoms of the SAME or DIFFERENT combine together.
Atoms are the smallest unit of matter that combines to form a compound.
ch3co2hGiven number of molecules = 300 molecules
In 1 mole of the given chemical compound, there are 2 atoms of carbon, 4 atoms of hydrogen and 2 atoms of oxygen
Number of atoms of oxygen = 2× Number of molecules of compound.
i.e
Number of atoms of oxygen = 2× 300
600 is the answer.

Mitosis is part of the cell cycle and includes all of the following steps except which one?.
Answer:
In cell biology, mitosis (/maɪˈtoʊsɪs/) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division. In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis, which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other.

Two years ago your orange orchard contained 70 trees, and the yield per tree was 70 bags of oranges. Last year you removed 10 of the trees and noticed that the yield per tree increased to 75 bags. Assuming that the yield per tree depends linearly on the number of trees in the orchard, what should you do this year to maximize your total yield?.
The number of trees that maximizes the yield is 105, so he should plant another 45 trees.
How to maximize the yield?
We know that the yield depends linearly on the number of trees. Remember that a linear relation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
And we know that if a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we have the two points:
(70 trees, 70 bags)
(60 trees, 75 bags)
Then the slope is:
[tex]a = \frac{7 bags - 75 bags}{70 trees - 60 trees} = -0.5 bags/tree[/tex]
Then the linear equation is, ignoring the units, something like:
y = -0.5*x + b
To find the value of b we can use one of the known points, for example, the first one.
(70, 70)
70 = -0.5*70 + b
70 = -35 + b
70 + 35 = b = 105
Then the linear equation is:
y = -0.5*x + 105
This gives the yield per tree, and the total yield for the x trees will be x times the above quantity, so we define the total yield as:
T = -0.5x^2 + 105*x
Notice that this is a quadratic equation with a negative leading coefficient, meaning that the maximum is at the vertex.
And for a general quadratic function a*x^2 + b*x + c the vertex is at:
x = -b/2a
So in our case, the vertex is at:
x = -105/(2*(-0.5)) = 105
So to maximize the total yield, he should plant 45 more trees, to get a total of 105 trees.

Answer:

Explanation:
The author uses historical evidence to claim them by:
"They use secondary-source quotations to show the plan that the commanders devised in Alligator Woods in August of 1791"
Further Explanation
Historical comparison is one of the qualitative research methods that examine aspects of social life that occurred in the past or that occurred in different cultures. Historical comparisons are often used as one of the most effective methods to examine how social change occurs and to look for basic traits that are common to society.
In comparison, there are many things that need to be done, namely making a clear concept, looking for facts (historical evidence) in the field, evaluating the facts obtained, organizing and uniting these facts, and writing the facts in the research report.
Broadly speaking, there are four types of facts '(historical evidence)' which are divided into primary sources, secondary sources, current records, and recollections. which will be explained as follows:
Primary sources are qualitative or quantitative data about events or social life in the past that were created and used in past periods, can be in the form of photos, films, newspapers, etc.
- Recollection is a person's argument or writing about his life based on his past or memory.
-The walking record uses pre-existing statistical research based on files, records or documents.
Secondary sources are qualitative and quantitative data used in historical research, which can be information about past events and settings written by historians not directly involved in the research.
In the text above, the writer explains that historical evidence is in the text that emphasizes the past, namely "August 1791"

% of consumers believe that cash will be obsolete in the next 20 years. Assume that consumers are randomly selected. Find the probability that fewer than of the selected consumers believe that cash will be obsolete in the next 20 years.
Using the binomial distribution, it is found that there is a 0.4113 = 41.13% probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.
For each consumer, there are only two possible outcomes, either they believe cash will be obsolete in the next 20 years, or they do not believe it. The belief of each customer is independent of any other customers, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.Researching the problem on the internet, we have that:
40.4% of consumers believe that cash will be obsolete in the next 20 years, hence p = 0.404.7 customers are surveyed, hence n = 7.The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is given by:
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{7,0}.(0.404)^{0}.(0.596)^{7} = 0.0267[/tex]
[tex]P(X = 1) = C_{7,1}.(0.404)^{1}.(0.596)^{6} = 0.1268[/tex]
[tex]P(X = 2) = C_{7,2}.(0.404)^{2}.(0.596)^{5} = 0.2578[/tex]
Then:
[tex]P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0267 + 0.1268 + 0.2578 = 0.4113[/tex]
There is a 0.4113 = 41.13% probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.

A club has 25 members, 20 boys and 5 girls. Two members are selected at random to serve as president and vice president. What is the probability that both will be girls?.
The probability that both will be girls is 1/30.
What is probability?Probability is a branch of mathematics that deals with the numerical description of how likely an event will occur or not.
To find the probability of both girls as president and vice president, first, we need to find the probability of picking a girl as the president and then also find the probability of picking a girl as the vice president and multiply both together.
The probability of picking a girl as the president(Pr(pres) = Total numbers of girls(n)/Total members in the club(M)Pr(pres) = n/M............Equation 1From the question,
Given:
M = 25 n = 5Substitute into equation 1
Pr(Pres) = 5/25Pr(Pres) = 1/5.Also, we need to find the probability of selecting a girl as the vice president.
Pr(v.p) = (n-1)/(M-1)Where:
Pr(v.p) = Probability of selecting a girl as the vice presidentFinally,
The probability that both will be girls is = (1/5)(1/6)The probability that both will be girls = 1/30Hence, The probability that both will be girls is 1/30.
