Type the correct answer in each box. Spell all words correctly, and use numerals instead of words for numbers. If necessary, use / for the fraction bar(s). The scatter plot presents Ray's monthly electricity bills and the amount of time Ray spent at home from January through August.

Using the scatter plot, find the correlation coefficient of this data set.

The correlation coefficient (r) is
.

The correlation coefficient can be improved by ignoring the bill for the month of
.

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
