Answer: Our required probability would be ![\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
Since we have given that
Let A be the event that Kirk has the ace of spades.
Let B be the event that everyone has an ace.
So, P(A) = ![\dfrac{1}{52}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B52%7D)
P(B) = ![\dfrac{4}{52}](https://tex.z-dn.net/?f=%5Cdfrac%7B4%7D%7B52%7D)
And P(A∩B) = ![\dfrac{1}{52}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B52%7D)
So, P(Kirk has the ace of spades | each of them gets an ace)
![\dfrac{P(A\cap B)}{P(B)}\\\\\\=\dfrac{\dfrac{1}{52}}{\dfrac{4}{52}}\\\\\\=\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B52%7D%7D%7B%5Cdfrac%7B4%7D%7B52%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B4%7D)
Hence, our required probability would be ![\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D)
Length = 60; Width = 36
The formula for Perimeter is P = 2L + 2W
Where L = length; W = width
192 = 2L + 2W
= 2(5x) + 2(3x)
= 10x + 6x
= 16x
192/16 = 16x/16
x = 12
Substitute the values:
192 = 2(5x) + 2(3x)
= 2(5*12) + 2(3*12)
= 2(60) + 2(36)
192 = 192

Read answer below :)
Step-by-step explanation:
So you know that it takes 90 seconds for 10 gallons, right? So you know it's 9 seconds per gallon, removing the 0's (which is the easiest way to simplify).
then you take 8 divided by 60 to find out how long it takes for one gallon.
My math shows this:
A = 9 seconds per 1 gallon
B = 7.5 seconds per 1 gallon
60 seconds for 8 gallons, 30 seconds for 4 gallons, 15 seconds for 2 gallons, 7.5 seconds for 1 gallon. (Notice how I divided by two each time until it was simplified)
