In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16 because 42 = (−4)2 = 16.

The point M is the midpoint of the line section PQ. Just a line fragment can have a midpoint. A line can't since it goes on uncertainly in the two bearings, thus has no midpoint. A beam can't on the grounds that it has just a single end, and henceforth no midpoint.
The Midpoint Formula works the very same way. In the event that you have to discover the point that is actually somewhere between two given focuses, simply normal the x-values and the y-values.
Answer:
Null Hypothesis, : p 85%
Alternate Hypothesis, : p > 85%
Step-by-step explanation:
We are given that it's been found that 85% of American adults suffer from triskaidekaphobia (fear of the number 13).
A USA Today/Gallup poll asked 1,006 randomly selected people 18 years old and older in telephone interviews "Suppose you checked into a hotel and were given a room on the thirteenth floor. Would this bother you or not?" 87% of the survey respondents answered they would be bothered.
Let p = <u><em>proportion of respondents who would be bothered about given a room on the thirteenth floor</em></u>
SO, Null Hypothesis, : p 85%
Alternate Hypothesis, : p > 85%
Here, <u>null hypothesis states that</u> the proportion of respondents who would be bothered about given a room on the thirteenth floor is less than or equal to 85%.
On the other hand, <u>alternate hypothesis states that</u> the proportion of respondents who would be bothered about given a room on the thirteenth floor is more than 85%.
Hence, this would be the correct null and alternative hypothesis.
Answer:
A)477
Step-by-step explanation:
Subtract 850 from 3,000
2150
Divide 2150 by 4.50 to find out how many people can be surveyed.
Yes because you’d still multiply it to get the same answer
