Answer:
2 seconds
Step-by-step explanation:
When the ball hits the ground, its height (h) will be 0. You can therefore set up the following equation:
Factor:
Since the time must be positive, it hits the ground after 2 seconds. Hope this helps!
Consider that
This means that a sport has a 0.4 chance of being sold out if 2 out of 5 events are sold out.
Rugby 7s has 3 out of 5 events sold out
Juntior athletics has 3 out of 5 events sold out
Volleyball has 2 out of 5 events sold out, so this is the sport you're looking for.
As for the second question, rugby and athletics are both sold out on two events (events 1 and 5). So, again, the chance is of 2 out of 5 events, which leads to a probability of

Answer:
width = 3.5 feet length = 8 feet.
Step-by-step explanation:
W=x
L=2x+1
Area=(2x+1)x=28
2x^2+x=28
2x^2+x-28=0
(2x-7)(x+4)=0
x=3.5,-4. It should be a positive number so W=3.5
2x+1=8 2x3.5=7 7+1 = 8 L=8
That area is 28 ft^2
width is 3.5 feet and length is 8 feet.
