<span>The best way to find the angular and linear coefficient is by assembling the reduced equation:
 
2x - y + 8 = 0
- y = - 2x - 8 .(- 1)
y = 2x + 8
 
The angular coefficient is the value that accompanies the X and the coefficient is the value that comes alone.
 
Angular Coefficient: 2
Linear Coefficient: 8
 
</span><span>If you want to find the values ​​X and Y, we have:

</span>2x - y + 8 = 0 
2(x - 8) = y 
<span>x - 8 = 2 </span>
<span>x = 2+8 </span>
x = 10 

2x - y + 8 = 0 
2*10 - y + 8 = 0
20 - y = - 8
- y = - 8 - 20
- y = - 28 .(-1)
y = 28

Confirm that the solution is correct:
2x - y + 8 = 0 
2*(10) - 28 + 8 = 0
20 - 28 = -8
- 8 = - 8 (TRUE)

Answer:

Binomial distribution requires all of the following to be satisfied:

1. size of experiment (N=27) is known.

2. each trial of experiment is Bernoulli trial (i.e. either fail or pass)

3. probability (p=0.14) remains constant through trials.

4. trials are independent, and random.

Binomial distribution can be used as a close approximation, with the  usual assumption that a sample of 27 in thousands of stock is representative of the population., and is given by the probability of x successes (defective).

P(x)=C(N,x)*p^x*(1-p)^(n-x)

where N=27, p=0.14, and C(N,x) is the number of combinations of x items out of N.

So we need the probability of <em>at most one defective</em>, which is

P(0)+P(1)

= C(27,0)*0.14^0*(0.86)^(27) + C(27,1)*0.14^1*(0.86^26)

=1*1*0.0170 + 27*0.14*0.0198

=0.0170+0.0749

=0.0919
