The measure of the angle EFD will be 68 degrees. The correct answer is option B.
<h3>What is an angle?</h3>
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that:-
The arc angle is 68 degrees and we need to find the angle EFD.
As it is given in the question that the angle suspended by the arc is 68 degrees so the angle EFD will also be equal to 60 degrees.
Therefore the measure of the angle EFD will be 68 degrees. The correct answer is option B.

Answer:
b-2=n
Step-by-step explanation:
2x^2 - 11 = 87
2x^2 = 87 + 11 = 98
x^2 = 98/2 = 49
x = sqrt (49) = + or - 7
In a normal distribution, the median is the same as the mean (25.3). The first quartile is the value of
such that
You have
For the standard normal distribution, the first quartile is about
, and by symmetry the third quartile would be
. In terms of the MCAT score distribution, these values are
The interquartile range (IQR) is just the difference between the two quartiles, so the IQR is about 8.8.
The central 80% of the scores have z-scores
such that
That leaves 10% on either side of this range, which means
You have
Converting to MCAT scores,
So the interval that contains the central 80% is
(give or take).
