If the correlation coefficient is 87, is its relationship considered to be strong positive, weak

positive, strong negative, weak negative, or no correlations

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

i dont know it

step-by-step explanation:

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
