Answer:
(5, - 4)
Step-by-step explanation:
Given a quadratic in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= -
x² - 10x + 21 ← is in standard form
with a = 1, b = - 10, so
= - = 5
Substitute x = 5 into the quadratic for the corresponding value of y
y = 5² - 10(5) + 21 = 25 - 50 + 21 = - 4
vertex = (5, - 4)
Answer: (0.3409, 0.4459)
Step-by-step explanation:
Given : Level of significance :
Then , significance level :
Since , sample size :
Using excel (by going in more formulas and then statistics), 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, a 95% confidence interval for the proportion of employees who have a daily commute longer than 30 minutes= (0.3409, 0.4459)
