Answer:

Step-by-step explanation:

given that a batch of 140 semiconductor chips is inspected by choosing a sample of 5 chips without replacement.

10 chips do not conform to customer requirements.

i.e. out of 140 chips 10 are defective and 130 are good

a) 5 chips can be selected form 140 chips in 140C5 ways

= 416965528

b) For containing exactly one non conforming chip we have one selected from 10 and other 4 selected from 130

No of ways = 10C1 (130C4)\\=10(11358880)\\=113588800

c) For atleast one nonconforming chip we can calculate as total - no non conforming

i.e. 416965528-130C5\\= 416965528-286243776\\=130721752

What makes two angles exterior versus interior ?<br>​
astraxan [27]

Answer:

Any angle that is on the inside of a shape is called an interior angle.

Step-by-step explanation:

Any angle that is on the outside of a shape is called an exterior angle. An exterior angle is made by extending one of the lines of the shape beyond the intersection point. ... Notice that the two angles make a straight line.

The discriminant for the equation f(x)=6x^(2)-x+c is 73. What is the value of c?
Andrews [41]

Answer:

c = -3

Step-by-step explanation:

The discriminant  is 73, that means we have:

(-1)^2-4*6*c=73

then: 1-24c=73

or -24c= 73 -1

-24c = 72

Then c = 72/-24= -3

The answer is -3

Hope that useful for you.

How many solutions does the absolute value equation have?<br><br> I x - 3 I + 2 = -2
choli [55]

9514 1404 393

Answer:

  the correct answer is marked

Step-by-step explanation:

When the graph of the left side of the equation does not intersect the graph of the right side of the equation, there are no solutions.

__

<em>Additional comment</em>

Even if you extend the domain to complex numbers, there are no solutions. The f(x) = |x| function always returns a positive real value, even for complex numbers.

Find the slope, y-intercept, and x-intercept of the graph of 3x+7y=14 Show your work in detail.
Vika [28.1K]
3x + 7y = 14

Subtract 3x from both sides

7y = -3x + 14

Slope is equal to -3.
