-- Reflecting across the x-axis makes all the x-coordinates the negative of
what they were before the reflection. The y-coordinates don't change.
-- Translating 2 units up makes all the y-coordinates 2 greater than
they were before the translation. The x-coordinates don't change.
You didn't give us a list of new coordinates, so there's nothing
to match with.
Answer:
C
Step-by-step explanation:
This one is quite easy. If you look angle M is slightly obtuse which means that it can't be A or B but it is to small to be D.
So we need have to understand that if we were to solve this, our answer would be 7 less than 'p' with that information we get p-7.
Answer:
The confidence interval becomes wider.
Step-by-step explanation:
The general form of a confidence interval is:

The critical value is based on the confidence level.
The confidence level is the probability that the true parameter value falls within a specific interval. The basic and most used confidence levels are 90%, 95% and 99%.
The confidence interval is directly proportional to the confidence interval.
Confidence Interval ∝ Confidence Level
On increasing the confidence level the confidence level widens. And on decreasing the confidence level the confidence level gets narrower.
Thus, when Gina changes the confidence interval to 99% the confidence interval becomes wider.
