The equation of the regression line y on x is given below, where y represents heat output in thermal units and x represents percent moisture content of a 1 kg block of wood. Estimate the moisture content of a block of wood with a heat output of 65 thermal units y=-0.470x+83.7

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
