We can't find what PT exactly is because we don't know TQ or x. However, we can find PT in terms of TQ!
Multiply the second equation by seven sixths to get:
Subtract
from both sides to get:
Substituting PT for 7x-24, we see that:
, which is our answer.
Answer:
4 games played = 1/56
5 games played = 5/56
6 games played = 15/56
7 games played = 35/56
Step-by-step explanation:
The probability of each time winning is 0.5
So there are a couple of ways the series could go.
- Team A could win all first 4 matches. We can depict this as A-A-A-A
- Team A could win 4, while having lost 1. Lets depict this a A-B-A-A-A
- Team A could win 4, while having lost 2. A-B-B-A-A-A
- Team A could win 4, while having lost 3. A-B-B-B-A-A-A
These 4 possibilities could be repeated with B winning as well. It should be noted that these are the only ways for the series to end. We find the number of permutations of each possibility above to find their probability.
I advise you to study 'how to permute identical objects' for this.
These permutations are stated below:
1. 4!/4! = 1
2. 
= 5
3 
= 15
4 
= 35
These are they ways A or B could win. The total is 1+5+15+35 = 56. The answer given thus reflects the possibilities.
Answer:
5: c=65 d=125 e=60
6: c= 58 d= 121 e=63
7. a=55 b=64 c=61
8. a=61 b=55 c=64
Step-by-step explanation: :)
Answer:
the number is 8
Step-by-step explanation:
8-3=5
6•5=30>24
expression: 6(x-3)>24
The distance between the two points would be the square root of 40. Hope this helped!
