What must a scientist do in order to develop a testable hypothesis brainly.
Answer: The correct answer is D. Ask a question that can be answered by making observations.
Explanation:
Basically, in order to develop a testable hypothesis, scientists must adhere to the guidelines of the scientific method.
The scientific method is usually understood to be a so-called hypothetical-deductive method, the core of which is to make hypotheses based on observations or measurements, to make predictions based on them and to check the validity of predictions by repeated experiments. More generally, the scientific method is a general way of obtaining solid knowledge, using many means of proof, both empirical and theoretical, to achieve certainty. The scientific method is a widely recognized tool in the scientific community for seeking objectivity, reliability and transparency in research.
Four students in ms. Alton's class shared the correlation coefficients derived from their data as follows: student a: r = –0. 87 student b: r = –0. 78 student c: r = 0. 79 student d: r = 0. 86 whose data had the strongest correlation? student a student b student c student d.
Considering the situation described above, the strongest correlation data is the "student a: r = –0. 87."
The correlation of variable is defined to be the strong correlation when the r-value is closer to +1 or -1.
Given that from the available options the r-value that is closer to +1 or -1 is that of student A which has -0.87, therefore, it is concluded that the Student A data had the strongest correlation.
Hence, in this case, it is concluded that the correct answer is option A. "Student A."

What is the most likely consequence of open pit mining on plant life? a. A dramatic reduction in the variety of plant species b. An increase in the number of plant species c. The complete loss of plant life in the area occupied by the surface mine d. A temporary decrease in plant populations please select the best answer from the choices provided.
The most likely consequence of open pit mining on plant life is a dramatic reduction in the variety of plant species. Open pit mining involves removing large amounts of rock and soil to extract valuable minerals. This process destroys the natural habitat of plants and disrupts the ecological balance.The correct answer is option A.
Here is a step-by-step explanation:
1. Open pit mining involves digging a large hole in the ground to extract minerals such as coal, gold, or copper. This process often requires the removal of trees, vegetation, and topsoil from the area.
2. The removal of vegetation and topsoil disrupts the natural ecosystem, as plants play a vital role in supporting other organisms. They provide food, shelter, and oxygen for animals, insects, and microorganisms.
3. The destruction of plants in the area leads to a loss of habitat for various plant species. Many plants are unable to survive or adapt to the harsh conditions created by open pit mining, such as exposure to sunlight, wind, and erosion.
4. The disturbed soil and exposed rock surfaces are often unable to support the growth of diverse plant species. This results in a reduction in the variety of plants that can grow in the area.
5. Additionally, the mining process may introduce pollutants and contaminants into the soil, water, and air, further damaging plant life.
In summary, open pit mining has a significant negative impact on plant life, resulting in a dramatic reduction in the variety of plant species. The destruction of habitat, disturbance of soil and rock surfaces, and pollution are all contributing factors to this consequence.

What is a Periodic Table?All identified chemical elements are arranged in rows (referred to as periods) and columns (referred to as groups) in the periodic table of chemical elements, also known as the periodic table, in ascending order of atomic number.
According to Los Alamos National Laboratory, the periodic table's horizontal rows are known as periods, and each period number represents the number of orbitals for the elements in that row.
Atoms have protons and neutrons as their nucleus. Outside of that are their electrons, which are grouped in orbitals; an atomic orbital is a mathematical concept that refers to the position of an electron and its wave-like activity.
According to the Royal Society of Chemistry, Russian chemist and inventor Dmitri Mendeleev are regarded as the "father" of the periodic table (opens in new tab). Mendeleev was a well-liked instructor in the 1860s at a Russian institution in St. Petersburg.

To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians and americans. The canadians spend an average of hours a week commuting, with a standard deviation hours. The mean and standard deviation for the sample of americans is hours and hours, respectively. The standard error of the difference of sample means is:.
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
Canadians
Sample size = 50Mean = 4.6Standard deviation = 2.9Americans
Sample size = 60Mean = 5.2Standard deviation = 1.3The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
The standard error of the Canadian sample is:
[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]
So, we have:
[tex]SE_1 = 0.41[/tex]
The standard error of the American sample is:
[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]
So, we have:
[tex]SE_2 = 0.17[/tex]
The standard error of the difference of sample means is then calculated as:
[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]
This gives
[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]
[tex]SE= \sqrt{0.197}[/tex]
Take square roots
[tex]SE= 0.444[/tex]
Hence, the standard error of the difference of sample means is 0.444
