1) either you'll get a negative number
Or
2) You'll get a positive Number..
But I'm guess you'll get a positive number
F(x) = -9 + 10.3x probably.
It's definitely not the first or last option as they have negative gradients (i.e. negative x-coefficient) and so represent a negative correlation. The data given tells us there is a positive gradient and so a positive correlation.
It could be the second option as the second and third are not so vastly different but I would go for the third because it appears to most closely fit the data pattern.
1. Combining like terms
2. Combining
Answer:
1
Step-by-step explanation:
We are given that
Numbers are in radians
Substitute x=-1
Substitute x=-0.25
Substitute x=-0.01
Substitute x=-0.005
Substitute x=0.005
Substitute x=0.01
Substitute x=0.25
Substitute x=1
Therefore,
