Answer:
Step-by-step explanation:
Probability of good given properly adjusted P(G/P) = .5
Probability of bad given properly adjusted P(B/P) = .5
Probability of inappropriately adjusted P(I ) = .1
Probability of properly adjusted P(P) = .4
Probability of good given inappropriately adjusted P( G/I ) = .25
Probability of bad given inappropriately adjusted P(B/I ) = .75
P( G ) = P(G/P) x P(P) + P( G/I ) x P(I )
P(P/G) = P(G/P) x P(P) / P(G/P) x P(P) + P( G/I ) x P(I )
= .5 x .4 / .5 x .4 + .25 x .1
= .20 / .20 + .025
.20 / .225
20 / 22.5
= 4 / 4.5 .
= 8 / 9 .
5 hundred thousand 6 thousand 7 hundred and 9
It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2
Use x+2y=8
Subtract 2y to make
x=8-2y
Plug this in to the other equation
3(8-2y)+2y=6
Distribute the 3
24-6y+2y=6
Combine like terms
24-4y=6
Solve
18/4=y, 9/2=y
Plug and solve for x
X+2y=8
X+(2*9/2)=8
X+9=8
X=-1
