The correlation coefficient (r) is used to describe the relationship between two variables.

If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.

correlation coefficient = 0.512
That means, there is a strong association between age and weight.
Answer:
-3
Step-by-step explanation:
f(x)= x²+3x-1
f(-1)= (-1)²+3(-1)-1
= 1-3-1
= -2-1
= -3
8*4-4/2+1
32-4/2+1
32-2+1
=31 answer
So, the answer to this question is 31
