<u>Answer:</u>

The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744  

<u>Solution:</u>

Total number of coils = number of good coils + defective coils = 88 + 12 = 100

p(getting two good coils for two selection) = p( getting 2 good coils for first selection ) \times p(getting 2 good coils for second selection)

p(first selection) = p(second selection) = \frac{\text { number of good coils }}{\text { total number of coils }}

Hence, p(getting 2 good coil for two selection) = \frac{88}{100} \times \frac{88}{100} =\bold{0.7744}

What is the solution of the system of equations? 6x-2y = 4 -9x+3y = 12
katrin2010 [14]

We will have the following:

First, we solve both equations for y, that is:

6x-2y=4\Rightarrow-2y=-6x+4\Rightarrow y=3x-2

&

-9x+3y=12\Rightarrow3y=9x+12\Rightarrow y=3x+4

From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.

I WILL MARK YOU BRAINLIEST!PLEASE SOLVE FOR X
polet [3.4K]

Answer and Step-by-step explanation:

We see that the bottom two lines are parallel, which makes angle x and angle 5 "same-side corresponding angles". By definition, same-side corresponding angles are congruent. That means angle x = angle 5.

Note that you didn't provide any measures, so it is impossible to actually figure out an exact degree. However, angle x is the same degree as angle 5.

Hope this helps!
