Answer:
(x − 3)² + (y − 4)² = 5
Step-by-step explanation:
The equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
First use the distance formula to find the radius:
d² = (x₂ − x₁)² + (y₂ − y₁)²
r² = (2 − 3)² + (6 − 4)²
r² = 1 + 4
r² = 5
Given that (h, k) = (3, 4):
(x − 3)² + (y − 4)² = 5
The answer is the fourth option: rises 4 and then falls 14

Answer:
Step-by-step explanation:
A quadratic equation has one root if the discriminant is 0.
That is we need for this particular question.
Compare the following to find :
The variable is representative of the variable here.
Plug in into :
Subtract 4 on both sides:
Divide both sides by 16:
Reduce:
Answer: (0.143, 0.257)
Step-by-step explanation:
Given : Level of significance :
Then , significance level :
Since , sample size : .
Critical value :
Also, the proportion of people said that they were fans of the visiting team :-
The confidence interval for population proportion is given by :-
Hence, the confidence interval for the population proportion with a 99% confidence level= (0.143, 0.257)
