Answer:
Option b
Step-by-step explanation:
Given that a researcher measures IQ and weight for a group of college students.
In general, we think that the weight has nothing to do with IQ of a person and hence not correlated.
But if we go deep, we find that after a certain weight, the person becomes lazy and inactive with a chance to have reduced IQ
Weight gain causes also health problems including less activity of both brain and body and hence there is a chance for less IQ
So we find that as weight increases iq decreases and when weight decreases, IQ increases.
Thus we can say that there is a negative correlation but not necessarily near to one.
Hence option b is right
Answer:
B

c(p)=12.5p+4500
12.5p means that for each part it will cost $12.50, but the initial cost is $4500.
Answer:
(D) ab + bc =ad
ab-ad = -bc
a(b-d) =bc
a = bc / b-d
