Answer whats the question?
Step-by-step explanation:
When estimating, compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to do mental arithmetic.
It is now possible to find the margin of error, the reason being that the confidence level is not given. However the 'standard error' of the sample mean can be found as follows:
Converted to a percentage, we get 1.11% which is the third choice of answer.
Answer:
B
-3
Step-by-step explanation:
B is correct but based on the fact that you selected it I'll assume you know why (comment if you want me to explain it)
Then for two lines to be paralell it means that their lines never intersect
The only way for this to be possible is if the lines have the same slope.
This means that the answer is -3
Answer:
c) It can be equal to 1.00 but it can also be greater than 1.00. It is never less than 1.00.
Explanation:
Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.
Or ,
n = c/v.
Since speed of the light 'v' in any medium is always be less than or equal to speed of the light in the vacuum 'c', thus, the index of refraction is always be greater than or equal to 1.0.
