Two factories I and II produce phones for brand ABC. Factory I produces 60% of all ABC phones, and factory II produces 40%. 10%

denpristay [2]

Answer:

0.3721 or 37.21%

Step-by-step explanation:

P(I) = 0.60; P(II) = 0.40;

P(not defective I) = 0.90; P(not defective II) = 0.80

The probability that the phone came from factory II, given that is not defective, is determined by the probability of a phone from factory II not being defective divided by the probability of a phone not being defective.

$P(II|not) = \frac{P(II)*P(not_{II})}{P(II)*P(not_{II})+P(I)*P(not_{I})}\\P(II|not) = \frac{0.40*0.80}{0.40*0.80+0.60*0.90}\\ P(II|not) =0.3721 = 37.21\%$

The probability is 0.3721 or 37.21%.

60 pts! <br><br>2x + 34 = 4(x + 5)<br><br>solve the equation for x.

erma4kov [3.2K]

Answer:

x=7

Step-by-step explanation:

expand 4(x+5): 4x+20

2x+34=4x+20

subtract 34 from both sides

2x+34-34=4x+20-34

2x=4x-14

subtract 4x from both sides

2x-4x=4x-14-4x

-2x=-14

divide both sides by -2

-2x/-2=-14/-2

x=7

That is just absolute value, basically what it means is take off whatever sign there was attached to it (such as a negative sign)
