Of the students at Wayland Middle School in the first semester, 48% made honor roll, 30% had perfect attendance, and 25% both made the honor roll and had perfect attendance. If a student is chosen at random, what is the probability that they have perfect attendance, given they made the honor roll? Write your answer as a decimal rounded to the nearest hundredths place.

i think the answer is d im not sure

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
