Military radar and missile detection systems are designed to warn a coutry of an enemy attack. Assume that a particular detectio
Tom [10]

Answer:

0.96 = 96% probability that at least one of them detect an enemy attack.

Step-by-step explanation:

For each radar, there are only two possible outcomes. Either it detects the attack, or it does not. The missiles are operated independently, which 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.

Assume that a particular detection system has a 0.80 probability of detecting a missile attack.

This means that p = 0.8

If two military radars are installed in two different areas and they operate independently, the probability that at least one of them detect an enemy attack is

This is P(X \geq 1) when n = 2. So

P(X \geq 1) = 1 - P(X = 0)

In which

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

P(X = 0) = C_{2,0}.(0.8)^{0}.(0.2)^{2} = 0.04

P(X \geq 1) = 1 - P(X = 0) = 1 - 0.04 = 0.96

0.96 = 96% probability that at least one of them detect an enemy attack.

What is the greatest common factor of 3562, 15b, and 5b?
Inga [223]

Hey there!

3,562: 1, 2, 13, 26, 137, 274, 1781, 3562

15b: 1, 3, 5, 15, b

5b: 1, 5, b

☆ Not all of the terms have b in it so we know We can't have that as an answer. Only two of the numbers have b in it

The one you see most common would be the biggest/greatest common factor would be

A parabola intersects the x-axis at x=3, equals, 3 and x=9.
kakasveta [241]

Answer: x is 6

Step-by-step explanation:

where a and b are x intercepts given to us.

So rewriting in factored form:

y = (x-3)(x-9)

so now you have to simplify it using the formula y= ax^{2}+ bx-c

y= x^{2}- 12x+27

so with this formula x=\frac{-b}{2a} we can find the x coordinate

x=\frac{-(-12)}{2(1)}

and the answer would be 6
