To solve a probability, you need to determine if the order is important or not. The word "<span>If a player can play any position," indicates that the team doesn't need to specify the order. So, the possible way to pick a team of 5 players out of 8 people would be:
8C5= 8!/ 5!</span>(8-5)!=
8C5= 8*7*6/ 3*2=56 ways

Answer:
C) 6.9 seconds
Step-by-step explanation:
h = -16t² + 96t + 100
When the ball hits the ground, h = 0.
0 = -16t² + 96t + 100
0 = 4t² − 24t − 25
Solve with quadratic formula:
t = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-24) ± √((-24)² − 4(4)(-25)) ] / 2(4)
t = [ 24 ± √(576 + 400) ] / 8
t = (24 ± √976) / 8
t = (24 ± 4√61) / 8
t = (6 ± √61) / 2
t = -0.91 or 6.9
Since t must be positive, t = 6.9 seconds.
