A manufacturing company makes multi-media software that includes video disk players (VDP) and audio disk players (ADP). It is observed that during the manufacturing, 4 out of 3000 VDPs may be defective and 3 out of 1000 ADPs may
be defective.
The company is concerned that the final software should not have any defective parts. What is the probability that the
software would not be defective?

106 emergencies

step-by-step explanation:

14.29%

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
