We are given the following information in the question:
Mean, μ = 5 ml
Standard Deviation, σ = 0.4 ml
We are given that the distribution of amount of dye dispensed is a bell shaped distribution that is a normal distribution.
Formula:
P(paint cans contain less than 5.54 ml of the dye)
Calculation the value from standard normal z table, we have,

- To turn
into vertex form, we need to complete the square on the right side
- Therefore, if
, then
completes the square on the right side
- This becomes
- This means that our function in vertex form is
Therefore, the vertex of the graph is .
