A manufacturing company produces parts that are good (90%), partially defective (2%), or completely defective (8%). These parts
Schach [20]

Answer:

The probability that a part is good given that it passed the inspection machine is P=0.978.

Step-by-step explanation:

As the inspection machine detect and discard any part that is completely defective, only the good and partially defective parts passed this inspection.

Then, if we have:

Probability of being a good part P(G)=0.90

Probability of being a patially defective part P(P)=0.02

Probability of being a completely defective part P(D)=0.08.

Probability of passing the inspection machine = 1-P(D)=1-0.08=0.92

Then, the probability of having a good part, given that it passed the inspection machine is:

P(G|Pass)=P(G)/P(Pass)=0.90/0.92=0.978

Go step by step to reduce the radical. V108 VOVO try You must answer all questions above in order to submit.
katen-ka-za [31]

To reduce the radical, you have to factorize 108.

108 is a multiple of 3, so to factorize it, you can divide it by 3

\frac{108}{3}=36

You can rewrite the square root as:

\sqrt[]{3\cdot36}=\sqrt[]{3}\cdot\sqrt[]{36}

The square root of 36 is equal to 6 so you can write the expression as:

\sqrt[]{3}\cdot\sqrt[]{36}=6\sqrt[]{3}

Find the measure of unknown angle​
inna [77]

Answer:

a = 85° , b = 30° , c = 65°

Step-by-step explanation:

∠ a and 85° are alternate angles and are congruent , so

a = 85°

∠ c and 65° are alternate angles and are congruent , so

c = 65°

a, b and c lie on a straight line and sum to 180° , that is

a + b + c = 180°

85° + b + 65° = 180°

150° + b = 180° ( subtract 150° from both sides )

b = 30°

Nate operates a hot dog stand. On Wednesday he used 5 bags of hot dog
netineya [11]
When you read this, you immediately get this feeling that the answer is
(1 and 3/4) times (5) .  The only problem is that it's kind of messy to
try and do the multiplication with (1 and 3/4) in that form, so it's a lot
easier if you change it to a different form ... you don't change the value
of the number, you just write it differently.

In place of (1 and 3/4), you could use  1.75 , or you could use  7/4 .
They're both exactly the same amount as (1 and 3/4), but they look
different, and they're easier to work with.

Since the problem wants the answer as a fraction or mixed number,
let's use  7/4  in place of  (1 and 3/4).

OK.  Five bags were used on Thursday, and (7/4) of that many were used
on Friday.

(7/4) x (5 bags) = <u>35/4</u> bags . . . . . That's the improper fraction.

The mixed number is  (<u>8 and 3/4</u>) bags.
