Answer:
x ≈ - 10.65, x ≈ - 5.35
Step-by-step explanation:
Given
(x + 8)² - 7 = 0 ( add 7 to both sides )
(x + 8)² = 7 ( take the square root of both sides )
x + 8 = ± 
( subtract 8 from both sides )
x = - 8 ± , thus
x = - 8 - ≈ - 10.65
x = - 8 + ≈ - 5.35
Answer:
f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)
Step-by-step explanation:
Given
The range of values is given as {0,1,2,3,4}
Because any computer can fail.
Given that the failure of the computers are independent and
The probability of failure is given as 0.0005.
Cumulative Distribution Function is the the probability that a random variable is less than or equal to a specific value
So, we'll take the binomial effect into consideration.
It is given as
f(x) = P(X ≤ x) = 4Cx * 0.0005^x * (1 - 0.0005)^(4 - x)
f(x) = P(X≤4) = 4Cx * 0.0005^x * 0.9995^(4-x)
