When a survey was conducted, .21 of the individuals surveyed had purchased Fresh, .41 of the individuals surveyed had recalled seeing the advertisement, and .13 of the individuals surveyed had purchased Fresh and recalled seeing the advertisement. a What proportion of the individuals surveyed who recalled seeing the advertisement had purchased Fresh? b Based on your answer to part , does the advertisement seem to have been effective? Explain.

Step-by-step explanation:

pr (p) = 0.21

pr (R)= 0.41

pr (P o R) = 0.13

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

answer: c
