Answer:

0.2027 = 20.27% probability that a non-defective product came from the second machine

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Non-defective product.

Event B: From the second machine.

Probability of a non-defective product:

100-13 = 87% of 30%(first machine)

100-9 = 91% of 20%(second machine)

100-9 = 91% of 50%(third machine).

So

[tex]P(A) = 0.87*0.3 + 0.91*0.2 + 0.91*0.5 = 0.898[/tex]

Non-defective and from the second machine:

91% of 20%. So

[tex]P(A \cap B) = 0.91*0.2 = 0.182[/tex]

What is the probability that a non-defective product came from the second machine

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.182}{0.898} = 0.2027[/tex]

0.2027 = 20.27% probability that a non-defective product came from the second machine

Answer:

If x=6 & y=2 then 9+3+x-y wil be

9+3+6-2

=12+6-3

=18-3

=15

Answer:

Given, x=6 and y=2

so the expression we have 9+3+x-y will become,

9+3+6-2 !

and by adding 9 & 3 we will get,

=12+6-3

Now adding 12 & 6 we get,

=18-3

now by subtracting 3 from 18 we get,

=15

Answer:

[tex]\frac{-27}{40}[/tex]

Step-by-step explanation:

[tex](\frac{-3}{8})[/tex]÷[tex]\frac{5}{9}[/tex]

[tex]\frac{-3}{8}[/tex]×[tex]\frac{9}{5}[/tex]

[tex]\frac{-27}{40}[/tex]

$4.60= 49 coins ( she only had dimes and nickles)

100 dimes= $1.00 times 4 is 400 dimes

12 nickels= .60 cents

                                              all of this will = to $4.60

Answer:

A

Step-by-step explanation:

the answer is

x+15=28

x=28-15

x= 13

Answer:

A

Step-by-step explanation:

x+15=28

move 15 to the other side

and change the + to -

x=28-15

x=13

Answer:

5 < -5 + |3a|

<=> 10 < |3a|

<=> 3a > 10 or 3a < -10

<=> a > 10/3 or a < -10/3

Answer:

5

Step-by-step explanation:

Subtract 1 from both sides. The equation becomes 2.5d + 6.25 = 3.75d

Subtract 2.5d from both sides. The equation becomes 6.25 = 1.25d

Divide 1.25 from both sides. You get 5 = d

Answer:

false

Step-by-step explanation:

I assume this is a true/false question.

The answer would be 'false'.

For 3 segments to make a triangle, each single side must be LESS than the sum of the other two.

Here, that is not the case. The '10' side is not less than 3+7.

You do this by figuring out the amounts of pure fruit juice in all.

Explanation:

Mixture:

5.10

gal pure juice

From Brand B:

8 gal 48% contains:

gal came from 9 gal of brand A

So the percentage of A is:

Answer:

A. 384.16

B. 2,401

C. 9,604

D. No

Step-by-step explanation:

Calculation to determine how large a sample should be taken for each desired margin of error

First step is to find σ which represent Population Standard deviation

σ=($50,000-$30,000)/4

σ=$20,000/4

σ = 5,000

Now let calculate how large a sample should be taken for each desired margin of error

Using this formula

n = (Za/2*σ/E)^2

Where,

Za/2=1-0.95/2

Za/2=0.05/2

Za/2=0.025

Z-score 0.025=1.96

Za/2=1.96

σ =5,000

E represent Desired margin of error

Let plug in the formula

a. $500

n = (1.96* 5,000/$500)^2

n=(9,800/$500)^2

n=(19.6)^2

n = 384.16

b. $200

n = (1.96*5,000/200)^2

n=(9,800/$200)^2

n=(49)^2

n = 2,401

c. $100

n = (1.96*5,000/$100)^2

n=(9,800/$100)^2

n=(98)^2

n = 9,604

Therefore how large a sample should be taken for each desired margin of error will be :

A. $500= 384.16

B. $200= 2,401

C. $100= 9,604

d.NO, Based on the information calculation i would NOT recommend trying to obtain the $100 margin of error reason been that it is highly costly compare to $500 margin of error and $200 margin of error.

The diagram is missing, so i have attached it.

Answer:

h = 7.7 cm

Step-by-step explanation:

From the attached image, we can see that the hypotenuse is 15 cm with the opposite side being h cm.

The angle is 31°

Thus, using trigonometric ratio, we have;

h/15 = sin 31

h = 15 sin 31

h = 15 × 0.5150

h = 7.725

Approximating to 1 decimal place gives;

h = 7.7 cm

Answer:

12

Step-by-step explanation:

1,000 milliliters in a liter. 3 liters, so divide 3,000 by 250, which will give you 12. she can water 12 plants.

Step-by-step explanation:

Lester can water 12 plants because there is 1000 milliliters in one liter so if we do 1000x3=3000÷250=12 plants being able to get watered
