Given rectangular prism ABCD. Choose all of the terms that best describe each of the sets of lines or points. Points D, G and J
collinear intersecting parallel noncollinear noncoplanar

Answer:
Step-by-step explanation:
The given parallelogram is attached.
First, we have to define some terms:
- Collinear means that they are on the same line, non-collinear is the opposite.
- Intersecting means that the point are touching each other, this apply to segments.
- Parallel means that they will never intersect, because they have the same slope or inclination, this apply to lines also.
- Coplanar means that points are in the same plane, non-coplanar is the opposite.
So, if we observe points D, G and J, from given options, they are non-collinear and non-coplanar, because they are not on the same line, nor plane.

Answer:
Check the explanation
Step-by-step explanation:
Here we have to first of all carry out dependent sample t test. consequently wore goggles first was selected at random for the reason that the reaction time in an emergency taken with goggles would be greater than the amount of reaction time in an emergency taken with not so weakened vision. So that we will get the positive differences d = impaired - normal
b)
To find 95% confidence interval first we need to find sample mean and sample sd for difference d = impaired minus normal.
We can find it using excel that is in the first attached image below,
Therefore sample mean = 0.98
Sample sd = 0.3788
To find 95% Confidence interval we can use TI-84 calculator,
Press STAT ----> Scroll to TESTS ---- > Scroll down to 8: T Interval and hit enter.
Kindly check the attached image below.
Therefore we are 95% confident that mean difference in braking time with impaired vision and normal vision is between ( 0.6888 , 1.2712)
Conclusion : As both values in the interval are greater than 0 , mean difference impaired minus normal is not equal to 0
There is significant evidence that there is a difference in braking time with impaired vision and normal vision at 95% confidence level .
