The calculator screen shows the linear regression for the data in the table What type of correlation does the correlation coefficient indicate?
LinReg
y = ax+b
a= -1.96341463
b = 19.09756098
r2 = .9817073171
r =-.9908114438
х 1 3 4 5 6 8 9
y 17 12 12 10 8 3 1

options:
a: a strong positive correlation
b: a weak positive correlation
c: a strong negative correlation
d: a weak negative correlation

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
