The box plot was created by using which pieces of data? a) an upper quartile of 56 and a median of 50 b) a lower quartile of 56 and a median of 50 c) a median of 56 and a lower quartile of 50 d) a median of 56 and an upper quartile of 50

A

The vertical line inside the box plot indicates the median which is 50

The right side of the box indicates the upper quartile which is 56

The left side of the box indicates the lower quartile which is 42

what is the image?

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
