Arlene is testing whether school is more enjoyable when students are making high grades. she asked 100 students if they enjoyed school and whether their gpa was above or below 3.0. she found that 30 of the 40 students with a gpa above 3.0 reported that they enjoyed school, and 15 of the 60 students with a gpa below 3.0 reported that they enjoyed school. what is the probability that a student with a gpa below 3.0 does not enjoy school?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
