Answer:

nitrogen is 13.8% of the compound

Explanation:

simply use the relative molecular mass;

RMM of compound = 39+14+(3*16)=101

% of nitrogen = 14/101 * 100= 13.8%

Use the sample data and confidence level given below to complete parts a through d.
4vir4ik [10]

Using the information given and the z-distribution, it is found that:

a) The point estimate of the population proportion is 0.5544.

b) The margin of error is: 0.0320.

c) The interval is: (0.5224, 0.5864).

d) The interpretation of the interval is: we are 95% sure that the true population proportion is between 0.5224 and 0.5864.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions has the bounds given by the rule presented as follows:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which the variables used to calculated these bounds are listed as follows:

  • \pi is the point estimate of the population proportion.
  • z is the critical value.
  • n is the sample size.

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of \frac{1+0.95}{2} = 0.975, so the critical value is z = 1.96.

From the sample, the sample size and the point estimate are given as follows:

n = 929, \pi = \frac{515}{929} = 0.5544

The margin of error is given by:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

M = 1.96\sqrt{\frac{0.5544(0.4456)}{929}}

M = 0.0320.

The interval is the point estimate plus/minus the margin of error, hence:

  • Lower bound: 0.5544 - 0.0320 = 0.5224.
  • Upper bound: 0.5544 + 0.0320 = 0.5864.

Which statements best compare the function of an atp molecule to a dna molecule?.
Andreas93 [3]

The main function of ATP molecule is to serve as an energy supply in the biochemical reactions that occur in an organism, while the function of DNA molecule is to contain the hereditary genetic information of an organism.

DNA is the base macromolecule of heredity, it is a nucleic acid that contains information on the hereditary characteristics of each living being.

ATP is a nucleotide-type organic molecule that is the universal chemical energy transporter in all cells.

  • DNA is responsible for storing all the genetic information of the individual, that is, the instructions for the synthesis of all the proteins that make up the body.

  • ATP is a fundamental molecule for various vital processes, since it is the main source of energy for the synthesis of complex macromolecules, such as DNA, RNA or proteins.

Therefore, we can conclude that ATP is a nucleotide that is essential for cells to obtain energy, while DNA presents the genetic information that living beings use to function.

What was the outcome of the war of roses
Alex73 [517]

An outcome of the War of Roses is that it was won by Henry Tudor for the Lancastrians and it eventually led to the Tudor dynasty.

<h3>What is a Civil War?</h3>

A Civil War refers to a state of intense conflict, riots, and crisis that typically exist between two or more communities, dynasties, towns, or states that were originally created within the same country.

Historically, the War of Roses were series of intense conflict in the mid-to-late fifteenth century between Lancaster and York over control of the English royal throne.

Based on historical information and records, we can infer and logically deduce that an outcome of the War of Roses is that it was won by Henry Tudor for the Lancastrians and it eventually led to the Tudor dynasty.
