After the results of an experiment, a scientist decides that a long-held scientific theory must be revised. The scientist modifies the theory and tells other scientists. Predict the scientists' reaction, and explain why they might react that way. Your answer:

Answers

Answer:

Other scientists will be surprised at him/her

Explanation:

Science is totally empirical in its approach to knowledge. Models and theories are proposed and revised based on the available mass of experimental evidence.

However, all scientific findings must go through a rigorous process of verification and replication by other scientists in other parts of the world before they become  widely accepted in the world of science.

The scientist ought not to have modified the existing theory based on his findings as an individual. His findings ought to go through rigorous verification because other extraneous factors that he may not have controlled adequately may have led to the results he obtained.

Other scientists will be surprised and disregard his claims about the long held scientific theory until his findings are satisfactorily verified by other scientists working in different parts of the world.

Checking account a charges a mouthly service fee $23 and wire transfer fee of $7.50 while checking account b charges a monthly service fee of $14 and wire transfer fee of $9.50 which checking account is the better deal if four wire transfers are made per month

Answers

Answer:

Checking account b is the better deal, because the total monthly fees amount to $52, while those for checking account a amount to $53.

Explanation:

Given:

monthly service fee of checking account a = $23

wire transfer fee of a = $7.50

monthly service fee of checking account b = $14

wire transfer fee of b = $9.50

To find:

which checking account is the better deal if four wire transfers are made per month?

Solution:

If four wire transfers are made per month then total monthly fees of both accounts is computed as follows:

Account a:

service fee of a + four wire transfers fee of a

23 + 4(7.50) = 23 + 30 = $ 53

Account b:

service fee of b + four wire transfers fee of b

14 + 4 (9.50) = 14 + 38 = $ 52

From the above results checking account b is the better deal because the total monthly fees amount to $52 while total monthly fees for checking account a amount to $53.
