Answer: 
OR
(15.102, 15.498)
Step-by-step explanation:
The formula to find the confidence interval
is given by :-
, where n is the sample size
= sample standard deviation.
= Sample mean
= Two tailed z-value for significance level of 
.
Given : Confidence level = 95% = 0.95
Significance level = 
sample size : n= 250 , which is extremely large ( than n=30) .
So we assume sample standard deviation is the population standard deviation.
thus , 
By standard normal distribution table ,
Two tailed z-value for Significance level of 0.05 :
Then, the 95% confidence interval for the mean credit hours taken by a student each quarter :-
Hence, the mean credit hours taken by a student each quarter using a 95% confidence interval. =(15.102, 15.498)
Answer:
The vertex is (5, 12)
Step-by-step explanation:
The vertex, from vertex form, is (h,k).
Vertex form is a(x - h)² + k
= 2(x - 5)² + 12
So h = 5, k = 12
The vertex is (5, 12).
I hope this helped!
The third choice , i mean you always have to go with c
The true statements are:
- There are 6 planes in the figure
- There is no other name for plane X
- The intersection of ADE and plane X is line AD
- A point non-collinear to point A is point C
<h3>The number of planes</h3>
This is the number of two-dimensional planes in the figure.
From the given figure, we have:
Hence, there are 6 planes in the figure.
<h3>Another name for plane X</h3>
There is no other name for plane X
<h3>Intersection of plane X and ADE</h3>
The plane X and shape ADE meets at line AD
Hence, the intersection of ADE and plane X is line AD
<h3>
Noncollinear point</h3>
This is the point that is not on the same line with another point.
Hence, a point non-collinear to point A is point C
