The probability that a certain kind of component will survive a shock test is 3/4. Find the probability that exactly 2 of the ne

Marina86 [1]

Answer:

Therefore the required probability is $=\frac{27}{128}$

Step-by-step explanation:

The probability of success is $\frac{3}{4}$

The number of trial = 4

X= the items survive out of 4

$P(x=r)=^nC_rq^{n-r}p^r$ p =the probability of success and q = the probability failure.

p= $\frac{3}{4}$ and $q=(1-\frac{3}{4})=\frac{1}{4}$

$\therefore P(X=2)=^4C_2(\frac{1}{4} )^2(\frac{3}{4} )^2$

$=\frac{4!}{2!2!} (\frac{1}{16} )(\frac{9}{16} )$

$=\frac{27}{128}$

Therefore the required probability is $=\frac{27}{128}$

The points G(1, 4) and H(3, 0) are on a coordinate plane. What is the approximate distance between points G and H?

oksano4ka [1.4K]

Then the approximate distance between the points is 4.47 units.

<h3>What is the approximate distance between points G and H?</h3>

We have the points G(1, 4) and H(3, 0), to get the distance between them we use the distance formula, we will get:

$D = \sqrt{(1 - 3)^2 + (4 - 0)^2} \\\\D = \sqrt{(-2)^2 + (4)^2}\\\\D = \sqrt{4 + 16} = \sqrt{20}$

And we know that √20 ≈ 4.47

Then the approximate distance is 4.47 units.
