The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

Given an incomplete sentence related to hypothesis and astronomy.

We are required to complete the sentence.

A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.

Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.

The statement can be completed by "do experiments and observations about the prediction of the hypothesis".

Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

A vasectomy is 99.97% effective, with pregnancy occuring extremely rarely after the 3 month wait period, once the procedure is

Margarita [4]

Answer:

Required probability = 91.72%

expected number = 2.4909

Expected number = 3332.33

probability = 8.28%

Required probability = 0.03%

Explanation:

given data

effective = 99.97%

time = 3 month

claims performed = 8,303

solution

At least one of the vasectomies perform not effective

so Required probability = 1 - P(All are effective) .................1

put here value and we get

Required probability = $1 - (0.9997)^{8303}$

Required probability = 1 - 0.0828

Required probability = 0.9172

Required probability = 91.72%

and

we know expected number is express as here

expected number is = n × p ..................2

put here value and we get

expected number = 8303 × (1 - 0.9997)

expected number = 8303 × 0.0003

expected number = 2.4909

and

Expected Number of vasectomies perform before patient return complain is

Expected number = $\frac{1}{p} - 1$ ..............3

put here value and we get

Expected number = $\frac{1}{(1-0.9997)} - 1$

Expected number = 3333.33 - 1

Expected number = 3332.33

and

when probability that 0 of his patients

probability = 100% - 91.72%

probability = 8.28%

and

when probability that the 2nd person he performed a vasectomy than

Required probability = p × q ...................4

put here value and we get

Required probability = (1-0.9997) × 0.9997

Required probability = 0.0003

Required probability = 0.03%

morpeh [17]

Answer:

Many countries use GDP per capita to compare the quality of life in different countries.

Explanation:

GDP per capita is gross domestic product divided by the number of inhabitants of a country. GDP is the sum of all goods in a country, and the higher the GDP, the more it demonstrates how developed that country is, and can be classified among poor, rich or developing countries.

Per capita GDP is used as an indicator of a country's quality of life, because the richer the country is, the more its citizens benefit. For this reason, we can conclude that many countries use per capita GDP to compare the quality of life of different countries.
