Answer:
Line Symmetry, Horizontal and Vertical Lines, 90 and 180 degrees
Step-by-step explanation:
It is line symmetry because you can fold the H, and it would overlap perfectly.
Horizontal and vertical lines because if you were to place a line in the middle both horizontally and vertically it would overlap.
90 and 180 degrees because the H would still have have symmetry if you flipped it on its side or upside down.
Answer:
I cant read It very Well, but I'm Pretty Shure that it is C
Step-by-step explanation:
A. The point estimate would be the average of the interval boundaries, which is the average of 48.2 and 56.4. This gives a point estimate of 52.3%.
b. The margin of error is the distance from either interval boundary to the point estimate. 56.4 - 52.3 = 4.1%.
c. Assuming this is solely going to be based on the class' decision, their grades should be scored on a curve. Although the margin of error is high and this seems to not have a significant distance from 50%, there is no "middle ground" in this option. We must either grade on a curve or not, and if we must choose one, we have to use to point estimate that is just slightly above 50%.
