Gnoma [55]

Answer:

The probability is;

0.0000003645

Step-by-step explanation:

The probability of packages being early p is 90% = 0.9

The probability of packages being late q will be 1-p = 1-0.9 = 0.1

So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem

That will be;

P(X = 2) = 10 C 2 0.9^2 0.1^8

= 0.0000003645

Find the points of intersection of the equation: xy=2 and x+y =4

Blizzard [7]

Answer: $\Large\boxed{(2+\sqrt{2},~2-\sqrt{x} )~~and~~ (2-\sqrt{2},~2+\sqrt{x} )}$

Step-by-step explanation:

Given the system of equations

$1)~xy=2$

$2)~x+y=4$

Divide x on both sides of the 1) equation

$xy=2$

$xy\div x=2\div x$

$y=\dfrac{2}{x}$

Current system

$1)~y=\dfrac{2}{x}$

$2)~x+y=4$

Substitute the 1) equation into the 2) equation

$x+(\dfrac{2}{x} )=4$

Multiply x on both sides

$x\times x+\dfrac{2}{x}\times x=4\times x$

$x^2+2=4x$

Subtract 4x on both sides

$x^2+2-4x=4x-4x$

$x^2-4x+2=0$

Use the quadratic formula to solve for the x value

$x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(1)(2)} }{2(1)}$

$x=2\pm\sqrt{2}$

Substitute the x value into one of the equations to find the y value

$xy=2$

$(2+\sqrt{2} )y=2$

$y=2-\sqrt{2}$

$OR$

$xy=2$

$(2-\sqrt{2} )y=2$

$y=2+\sqrt{2}$

Therefore, the points of intersection are

$\Large\boxed{(2+\sqrt{2},~2-\sqrt{x} )~~and~~ (2-\sqrt{2},~2+\sqrt{x} )}$

Hope this helps!! :)
