Which function passes through the points (2, 15) and (3, 26)?
2 answers:
Answer: The correct option is (B)
Step-by-step explanation: We are given to select the function that passes through the points (2, 15) and (3, 26).
Since the function passes through two points, so it must be a linear function in two variables.
That is, the graph of the function will be a straight line.
Now,
the slope of the line passing through the points (2, 15) and (3, 26) is given by
Since the line passes through the point (2, 15), so the equation of the line will be
Thus, the required function is
Option (B) is correct.

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.
