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:
x = , 6
Step-by-step explanation:
The values of a variable are not possible when it makes the equation divide by 0. To find these values, we need to set each of the denominators equal to 0:
3x + 5 = 0
3x = -5
x =
x - 6 = 0
x = 6
Answer:
Solutions of the given equations is (-3,2).
Step-by-step explanation:
Here the equations given are y = -x²-6x-7------(1)
and y = 2---------(2)
Now we substitute the value of y from equation (2) into (1)
2 = -x²-6x-7
x²+6x+7 = -2
x²+6x+7+2 = 2-2
x²+6x+9 = 0
x²+3x+3x+9 = 0
x(x+3)+3(x+3) = 0
(x+3)(x+3) = 0
therefore value of x is x = -3
Therefore the solution is (-3,2).
X^-3
Anything to the power of 0 is 1 so
X^-3/1= X^-3
