From the given scatter plot we can see that variables are positively correlated because they are moving in the same direction.
Since we know that the positive correlation is a relationship between two variables such that they increase or decrease together.

Option A. $17.28
Step-by-step explanation:
we have the expression for the cost

In this problem we have

substitute the given values in the expression to obtain the cost

The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.
