Two assembly lines I and II have the same rate of defectives in their production of voltage regulators. Six regulators are sampl

Kamila [148]

Answer:

0.4546

Step-by-step explanation:

nCr = n!/(n-r)!r!

Number of ways of selecting the four defective voltage regulators from 12 = 12C4 = 12!/(12-4)!4! = 12!/8!4! = (12 *11*10*9)/(4*3*2*1)

12C4 = 495 ways

Number of ways of selecting 2 defectives from line 1 = 6C2 * 6C2

6C2 = 6!/(6-2)!2! = 6!/4!2! = (6*5)/(2*1) = 15

6C2 * 6C2 = 15*15 = 225 ways

Probability = Number of possible outcomes/ Number of total outcomes

Probability that exactly 2 of the defective regulators came from line 1 = 225/40.95 = 0.4546

Which expression is equivalent to r^m ÷ r^n?

Andre45 [30]

R^m ÷ r^n is equal to r^(m-n).

For example, 2^5 ÷ 2^3 = 2^2.

Is that what you mean?

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!

Hello and Good Morning/Afternoon

Let's take this problem step-by-step:

To find the solution to a system of equation

⇒ must set the equations equal to each other

⇒ and solve

Let's put that into action

$x^2-2x+3 = -2x + 12\\x^2-2x+2x+3-12=0\\x^2-9=0\\(x+3)(x-3)=0$

At this point, to make the whole thing equal zero

⇒ either 'x+3' or 'x-3' equals zero

⇒ must find 'x' that satisify either equation

$x-3=0\\x=3\\\\x+3=0\\x=-3$

Let's find the corresponding f(x) to each x-value

$f(3) = -2(3)+12=-6+12 = 6\\\\f(-3) = -2(-3) + 12=6+12=18$

Therefore the solutions are (3,6) and (-3,18)

Answer: (3,6), (-3,18)

Hope that helps!
