Running = 2/3
Swimming = 5/6
5/6 - 2/3 = 5/6 - 4/6 = 1/6
Answer : She spent 1/6 hour longer swimming than running.
Answer:
Total songs = 15
Liked songs = 3
Un liked songs = 15-3=12
Find the probability that among the first two songs played
(a) You like both of them.
Probability that among the first two songs played you like both of them = 
(b) You like neither of them.
Probability that among the first two songs played you like neither of them = 
(c) You like exactly one of them.
Probability that among the first two songs played you like exactly one of them = 
(d) Redo (a)-(c) if a song can be replayed before all
(a) You like both of them. Would this be unusual?
Probability that among the first two songs played you like both of them = 
(b) You like neither of them.
Probability that among the first two songs played you like neither of them = 
(c) You like exactly one of them.
Probability that among the first two songs played you like exactly one of them = 
Answer:
Approximately 3.8 seconds
Step-by-step explanation:
H(x)=-16x^2+60x+4
We want to find when the ball hits the ground, or where the zeros are
0 =-16x^2+60x+4
Using the quadratic formula
-b ±sqrt(b^2 -4ac)
---------------------------
2a
-60 ±sqrt(60^2 -4*-16*4)
---------------------------
2(-16)
-60 ±sqrt(3600+256)
---------------------------
-32
-60 ±sqrt(3856)
---------------------------
-32
We want the positive value for time
-60-62.09669879
---------------------------
-32
3.815521837
Approximately 3.8 seconds
9/36 in the simplest form is 1/4
The answer is in the pic. I hope it helps : )
Have a nice day.
