Answer:
Step-by-step explanation:
You already have this set up to answer your question. This quadratic is in work form, aka vertex form, where the vertex is (3.5, 15). The first coordinate of the vertex is the time it takes to reach its max height, which is the second coordinate of the vertex. So it takes 3.5 seconds to reach a max height of 15 meters.
10 different pairs. Since there are 5 different brands you simply add 4+3+2+1 to get 10.

Answer:
0.88 = 88% probability that the next apples he picks will be good
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, we have the number of outcomes a priori, that is, before the trial.
What is the experimental probability that the next apples he picks will be good?
250 apples, 250 - 30 = 220 good.
0.88 = 88% probability that the next apples he picks will be good
