Rin incorrectly calculated the mean absolute deviation for in which step did Rin make an error?
the data set 25,25,31,36,38.Her work is shown here.
1. Find the mean.
Mean - 25 - 25 31+ 36 38 - 155 31
2. Find each absolute deviation.
Absolute deviations:6,6,0,5,7
3. Find the mean absolute deviation.
MAD = 6 + 0 +5.7 - 18 - 4.5

it's both, now can you answer my most recent question?

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
