Answer:
The correct option is B.
Step-by-step explanation:
A plane extends infinitely in two dimensions. It has no thickness.The plane has two dimensions: <u>length and width</u><u>.</u> But since the plane extends infinitely,the length and width cannot be measured.
Lets take an example of a flat sheet of metal. Imagine a flat sheet of metal. Now make it infinitely large in both directions. This means that no matter how far you go, you never reach its edges. Now imagine that it is so thin that it actually has no thickness at all. In spite of this, it remains completely rigid and flat. This is the 'plane' in geometry.
This question includes some misspelled words; here is the correct question:
Which point of view is most likely to be unreliable in a story?
All points of view in a story are equally reliable.
The first person narrator is most likely to be unreliable.
All points of view in a story are equally unreliable.
The third-person point of view is most likely to be unreliable.
The correct answer is The first-person narrator is most likely to be unreliable.
Explanation:
In a narrative text, an unreliable narrator implies the narrator lies on purpose to the reader, or his/her version of the story is not completely accurate. This feature of narration occurs mainly if the story, novel, etc. includes a first-person narrator. This is because in a first-person narrator, the thoughts, feelings, and point of view of one of the characters prevail, and this causes the events told are subjective and therefore more likely to be inaccurate. Also, this does not occur if there is a third-person narrator because in this case the narrator acts as an observer and this makes it more objective.
(1/2) ^2 = 1/2 * 1/2 = 1/4
1/4 < 1/2
Answer: B. 
Step-by-step explanation:
Let 
be the proportion of all U.S. adults that smoked in 1995. Let 
denote the proportion of all U.S. adults that smoked in 2000.
Objective for the study : Whether the proportion of U.S. adults that smoke declined during the 5-year period between the samples.
i.e. 
Alternative hypothesis
is the statement containing population parameter that shows there is significant difference between the groups being tested.
⇒
Null hypothesis
is the statement containing population parameter that shows there is no significant difference between the groups being tested.
⇒
Hence, The hypotheses to test in this problem are
Hence, the correct answer is B.
