The difference between two numbers is 275.the smaller number is 236 what is the sum of both numbers

kirza4 [7]

Answer:

747

Step-by-step explanation:

let the 2 numbers be x and y with x > y, then

x - y = 275 ( the difference of the 2 numbers ) and

x - 236 = 275 ( the smaller number y = 236 )

Add 236 to both sides

x = 511

Thus x = 511 and y = 236, thus

x + y = 511 + 236 = 747

A k out of n system is one in which there is a group of n components, and the system will function if at least k of the componen

Solnce55 [7]

Answer:

0.9606 = 96.06% probability that the system will function tomorrow

Step-by-step explanation:

For each component, there are only two possible outcomes. Either it works, or it does not. Components are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Probability of a component working:

0.7 of 0.2(rain)

0.9 of 1 - 0.2 = 0.8(no rain). So

$p = 0.7*0.2 + 0.9*0.8 = 0.86$

0.86 - 86% probability that the system will function tomorrow

6 components:

This means that $n = 6$

What is the probability that the system will function tomorrow

This is

$P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 4) = C_{6,4}.(0.86)^{4}.(0.14)^{2} = 0.1608$

$P(X = 5) = C_{6,5}.(0.86)^{5}.(0.14)^{1} = 0.3952$

$P(X = 6) = C_{6,6}.(0.86)^{6}.(0.14)^{0} = 0.4046$

$P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6) = 0.1608 + 0.3952 + 0.4046 = 0.9606$

0.9606 = 96.06% probability that the system will function tomorrow
