Answer:
And the 95% confidence interval would be given (0.419;0.481). And the best option would be:
b. .419 to .481
Step-by-step explanation:
We know the following info:
sample size selected
represent the number of people who favored Candidate AT
The sample proportion would be:
The confidence interval would be given by this formula
For the 95% confidence interval the value of and , with that value we can find the quantile required for the interval in the normal standard distribution.
And replacing into the confidence interval formula we got:
And the 95% confidence interval would be given (0.419;0.481). And the best option would be:
b. .419 to .481
Which set of ordered pairs does not represent a function? O {(4, -6), (-5,5),(-6,0), (7,0)} O {(0, -4), (9,6), (2,8), (8,8)} O {
Ipatiy [6.2K]
Function is a set of ordered pairs that do not have same domain or x-value. That means in a set of ordered pairs, the domain cannot have same value.
The only relation that isn't function here is the last choice because in a set of ordered pairs, there are two -5's which is repetitive. Other choices do not have same x-values in one set except for the last choice.
Answer
- {(-5,2),(3,-9),(-1,8),(-5,9)}
Hope this helps and let me know if you have any doubts!

Answer:
Step-by-step explanation:
Answer:
A) 47.17
B) 10.2 feet
Step-by-step explanation:
dont forget to switch the calculator to degrees when doing this
For A)
arcsin(11/15)=angle of elevation
47.17=angle of elevation
For B)
tan(47.17)=11/x
11/tan(47.17)=x
10.2=x
