t = p - 4 or p - t = 4
answer is A first one
Answer:
a) 4,096
b) 0.000244
Step-by-step explanation:
a)
By the Fundamental rule of counting, there are
4*4*4*4*4*4 = 4,096
ways of forming six-digit arrangements where each position has 4 possibilities (1 to 4)
b)
The probability of entering the correct code on the first try, assuming that the owner does not remember the code is
1/4096 = 0.000244
You would do 2 divided by 9 to get that each person would have 2/9 of a gallon or .22 of a gallon. I hope this helps.
You start by subtracting: 16000-1200= 14800
Then you divide 14800 by how many feet the plane rises per minute
14800/945=16 minutes
The answer is 16 minutes
Let's write miles over hours
80 / 2 = 200/ x
cross multiply
80x = 400
divide both sides by 80
x = 5
It will take 5 hours to cover 200 miles
Hope this helps :)
