So far, they sold 16 lemonades out of
27+16+12+9=64 drinks.
So, 16/64 = 1/4 of the drinks sold so fare was lemonade. That's the expected probability of someone ordering a lemonade for the next drink.

Answer:
<h3>
f(x) = -²/₄₉(x - 2)² + 4</h3>
Step-by-step explanation:
The vertex form of an equation of the parabola:
f(x) = a(x - p)² + q
vertex is (2, 4) so p = 2, q = 4
so:
f(x) = a(x - 2)² + 4
the parabola goes through the point (-5, 2) so x=-5, f(x)=2
2 = a(-5-2)² + 4
- 2 = a(49)
a = -²/₄₉
Therefore the equation of the parabola in vertex form:
f(x) = -²/₄₉(x - 2)² + 4
