1/3
Step-by-step explanation:
sum of numbers = 30 marbles
probability = 10/30 or simplified 1/3
7 and 10 is half
so we expect the people come to wedding half of 120÷2=60 people
i just try
Max height is the vertex
convert to vertex form (y=a(x-h)^2+k) by completeing the square
h(t)=-16(t²-4t)+80
h(t)=-16(t²-4t+4-4)+80
h(t)=-16((t-2)²-4)+80
h(t)=-16(t-2)²+64+80
h(t)=-16(t-2)²+144
vertex is (2,144)
at t=2, the height is 144
max height is 144ft
