A satellite system consists of n components and functions on any given day if at least k of the n components function on that da
Charra [1.4K]

Answer:

P = αP(x≥k,p1) + (1-α)P(x≥k,p2)

Step-by-step explanation:

The probability that k of n components function on a day follows a binomial distribution, so the probability is:

P(k,p)=nCk*p^{k}*(1-p)^{n-k}

Where p is the probability that a component function and nCk is \frac{n!}{k!(n-k)!}

So, the probability that at least k of the n components function on a day is:

P(x≥k,p) = P(k,p) + P(k+1,p) + P(k+2,p) + ... + P(n,p)

Then, if it is rain, the probability of the function p is equal to p1, if it isn't the probability p is equal to p2, so the probability P that the satellite system will function is:

P = αP(x≥k,p1) + (1-α)P(x≥k,p2)

Where, P(x≥k,p1) and P(x≥k,p2) are equal to:

P(x≥k,p1) = P(k,p1) + P(k+1,p1) + P(k+2,p1) + ... + P(n,p1)

P(x≥k,p2) = P(k,p2) + P(k+1,p2) + P(k+2,p2) + ... + P(n,p2)

mash [69]

Answer:

617000

Step-by-step explanation:

Division reverses multiplication.

If the total population of Charlotte which we'll call 'x' follows

x * 0.05 = 30850, then

30850 / 0.05 = x

x = 617000
