Ben's favorite deli says the average serving time is 12 minutes. Ben notices that the wait time at the deli varies at different
patriot [66]

Answer:

Step-by-step explanation:

Given Ben's observations when the wait time is as advertised represented by the equation 2|x − 2| − 12 = 0, to get the times when the serving time is as advertised, relative to noon, we will calculate for the value of x in the equation;

Note that the modulus of the function |x-2| will return both positive and negative value.

For the positive value of |x-2|;

2|x − 2| − 12 = 0

2(x − 2) − 12 = 0

open the parenthesis

2x-4 - 12 = 0

2x - 16 = 0

add 16 to both sides

2x-16+16 = 0+16

2x = 16

x = 16/2

x = 8

For the negative value of |x-2|;

2|x − 2| − 12 = 0

-2(x − 2) − 12 = 0

open the parenthesis

-2x+4 - 12 = 0

-2x - 8 = 0

add 8 to both sides

-2x-8+8 = 0+8

-2x = 8

x = -8/2

x = -4

<em>Hence the times when the serving time is as advertised, relative to noon are 8minutes and 4minutes </em>

: A personal computer manufacturer buys 36% of its chips from Japan and the rest from the United St...
meriva

Answer: 0.9862

Step-by-step explanation:

Given : The probability that the chips belongs to Japan: P(J)= 0.36

The probability that the chips belongs to United States : P(U)= 1-0.36=0.64

The proportion of Japanese chips are defective : P(D|J)=0.017

The proportion of American chips are defective : P(D|U)=0.012

Using law of total probability , we have

P(D)=P(D|J)\times P(J)+P(D|U)\times P(U)\\\\\Rightarrow\ P(D)=0.017\times0.36+0.012\times0.64=0.0138

Thus , the probability that chip is defective = 0.0138

Then , the probability that a chip is defect-free=1-0.0138=0.9862
