Answer:
the probability that the rack ends up in alphabetical order is 0.0001984
Step-by-step explanation:
Given that:
You own 24 CDs. You want to randomly arrange 7 of them in a CD rack.
Th probability that the rack ends up in alphabetical order can be determined by taking note of the permutations and combinations.
From above; all possible permutations of size 7 we can derive from 24 is
24P7
Similarly,we are meant to estimate all the possible ways a unique set of 7 things can be gotten from a total of 24
i.e
24 C7
∴
The probability =
=
=
=
= 0.0001984
the probability that the rack ends up in alphabetical order is 0.0001984
Answer:34a
Step-by-step explanation:
because 6a-4=2a
4a+28=32a
2a+32a=34a
Step-by-step explanation:
When Delta(b^2-4ac) is greater than 0, the quadratic equation has two distinct real solutions, when it is equal to 0, the quadratic equation has one real solution, when it is negative, it has no real solutions.
Answer:
6.5*4=26 For problems like these multiply the amount of time by the distance traveled each unit of time.
