Answer:
(C) 100
Step-by-step explanation:
The average of a data set is just all the numbers added up divided by the amount of numbers.
If we already have 4 pieces of data and we're looking for one more, we have 5 data pieces.
This means that the sum of all of the numbers in the data set will be
if the mean is 91.
We can find the missing value by adding up what we know and subtracting from 455.

So Abby needs a 100% on her fifth history quiz to have an average of 91 on all her quizzes.
Hope this helped!

Answer:
D. GH = FH because FG is perpendicular to the radius of a circle A.
Step-by-step explanation:
A circle has different parts which include but no limited to; diameter, chord, radius, segment, sector, circumference etc. This, it can be observed that FG is a chord on circle A, and a chord is always perpendicular to the radius of the circle that bisects it. This implies that FG has been bisected into two equal haves of FH and GH by the radius AH.
Therefore, since FG is at a right angle to AH, then it is true that GH = FH. So that the appropriate answer to the given question is option D.
