Mr andretti has two options for driving to work, the freeway and the back way. He's curious about how long it takes to get to work by each route, so he randomly chooses a different route each day on the basis of a coin flip. After 30 trips to work, he looks at the results. Below are the dot plots of the two distributions

If it’s 15 minutes it would be 159

Hello!   ==i would say:   spring tides are the highest, while neap tides are the lowest.==hope this ! : )

You're asking in the ap section, so i'll give the ap calculus-style answer. alternatively, you can find the vertex of the parabola and use the "y"-coordinate as the answer.

the maximum height can occur at a critical number, that is, a number  such that  .

the derivative of  can be calculated as follows:



find a value of  that is a zero of the derivative:


this is parabola that is opening downward; we can assume there is a maximum at  .

to find that maximum, calculate  .

If you messed up then it’s up to you to do the right thing but in my opinion i juts like doing things right
