Mr. O'Lear is conducting an experiment that involves 10 plants. He initially determined that the plants hada mean height of 72 centimeters and a mean absolute deviation of 8.5 centimeters. He later discovered that he made two errors in the height measurements of two plants. The table shows the incorrect and the correct measurements of the two plants. a) What is the correct mean height of the 10 plants? b) What is the correct mean absolute deviation of the 10 plants?

step-by-step explanation:

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
