A company has 2 machines that manufacture widgets. An older machine manufactures 25% defective widgets, while the new machine ma
Bingel [31]

Answer:

73.90%

Step-by-step explanation:

Let Event D=Defective,  D' = Non Defective

Let Event N=New Machine, N' = Old Machine

From the given information:

P(D|N')=0.25\\P(D|N)=0.09\\P(N)=0.7\\P(N')=0.3

We are required to calculate the probability that a widget was manufactured by the new machine given that it is non defective.  

i.e. P(N|D')

P(D'|N')=1-P(D|N')=1-0.25=0.75\\P(D'|N)=1-P(D|N)=1-0.09=0.91

Using Baye's Law of conditional Probability

P(N|D')=\dfrac{P(D'|N)P(N)}{P(D'|N)P(N)+P(D'|N')P(N')} \\=\dfrac{0.91*0.7}{0.91*0.7+0.75*0.3}\\ =0.73897\\\approx 0.7390

Therefore given that a selected widget is non-defective, the probability that it was manufactured by the new machine is 73.9%.

1/6,1/9,2/27,4/81 geometric sequence next value?
Blababa [14]
If you would like to know the next value, you can calculate this using the following steps:

1/6, 1/9, 2/27, 4/81, x = ?

1/9 / 1/6 = 1/9 * 6 = 6/9 = 2/3

So, if we would like to know what is the next value of this geometric sequence, you have to multiply 4/81 by 2/3:
4/81 * 2/3 = 8/243

The correct result would be 8/243.

m_a_m_a [10]

Answer:

B, 36 degrees

Step-by-step explanation:

Because AB and CB are congruent, so are arcs AB and CB. Therefore, 3x+12=6x-12

24=3x

x=8

3x+12=3(8)+12=24+12=36 degrees, or answer choice B. Hope this helps!
