You would plug in the y=9 into the first equation and then have the expression 9=9x-9
. After going through the first steps of solving an expression you would get 18=9x. X=2. Then you would plug in the x value into the first expression to get y=9.
Answer:
It would be 5
Step-by-step explanation:
Answer:
<A=50
Step-by-step explanation:
85+x+55+x+50=180
2x+190=180
2x=180-190
2x=-10
x=-5
A=x+55
A=-5+55
A=50
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)
