Answer:
There are 104.5 centiliters of paint in the mixture.
Step-by-step explanation:
Since you have a total of .50 liters of paint you would just look at the measurement and split it in half which would give you 100 centiliters and then you would add the 4.5 centiliters to the 100 and you would get 104.5 centiliters of paint.
Exponential Function.

Also the shown graph is a decreasing graph.

The equation above is the equation of the graph that is shown in the picture.
Mean = 133.9
then calculate the z value
with z value you will find out the p value on a table.
if the p value is below .05 reject the null hypotheses
