Answer:
0.3216 = 32.16% probability that, in any seven-day week, the computer will crash less than 3 times
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval
Mean of 0.5
7-day week, so 
What is the probability that, in any seven-day week, the computer will crash less than 3 times?
In which
0.3216 = 32.16% probability that, in any seven-day week, the computer will crash less than 3 times
Answer:
A positive 3x
Step-by-step explanation:
since both parts have the same variable you could add them or subtract them together
(3x-7x)+(3x+4x)
You will subtract 3x-7x which will give you a negative 4x
You will do the same on the other side
Add 3x+4x and it will give you a positive 7x
-4x+7x=will give you an positive 3x

Answer: 21
4/7 = 12/x
Multiply each side by x, so the x drops out on right side:
(4/7)x = 12
Distribute x:
4x/7 = 12
Multiply each side by 7, so the 7 drops out on left side:
4x = 84
Divide:
x = 84/4
x = 21
.56 because 4 x 14 = 56 then 56 / 100 = .56
