1% of the parts produced by a factory are defective. Suppose the test for defective parts has a 99.5% accuracy and a 0.6% false positive rate. SUppose you pick a part and receive a positive test result. WHat is the probability that the part is indeed defective

Answers

Answer 1

Using conditional probability, it is found that there is a 0.6262 = 62.62% probability that the part is indeed defective.

Conditional Probability

[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 problem:

Event A: Positive test result.

Event B: Defective.

For the probability of a positive test result, we consider two scenarios.

99.5% of 1%(defective).0.6% of 100 - 1 = 99%(false positive).

Hence:

[tex]P(A) = 0.995(0.01) + 0.006(0.99) = 0.01589[/tex]

The probability of a positive test result and being defective is:

[tex]P(A \cap B) = 0.995(0.01)[/tex]

The conditional probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.995(0.01)}{0.01589} = 0.6262[/tex]

0.6262 = 62.62% probability that the part is indeed defective.

Solve: 2 x + 5y + 5 = 0
2y=3x+17.
Find x and y

Answers

Answer:

x = -5 and y = 1

Step-by-step explanation:

a) 2x + 5y +5 = 0

a) 2x + 5y = -5

b) 2y = 3x + 17

b) y = 3/2x + 17/2

a) 2x + 5(3/2x + 17/2) = -5

a) 2x + 15/2x + 85/2) = -5

a) 19/2x = -5 - 85/2

a) 19/2x = -95/2

a) x = (-95/2) / (19/2)

x = -5

b) 2y = 3(-5) + 17

b) y = 2/2

y = 1

Arnie is an American teaching English in Japan, and he currently has 55,000

90.77 Japanese yen to 1 U.S. dollar = 91.24 Japanese yen, what happens to
the value in U.S. dollars of the money in Arnie's bank account?

Answers

Answer:

The worth of his bank account in USD would go from $605.93 to $602.81 cents. This is because it due to the change in exchange rates it requires more yen to make up a dollar which would cause it to take more yen to make a dollar. I hope this helps :D

What is the range of the function y= 2e7-1?

Answers

Answer:

The range of y = ex is all numbers greater than 0, so since the function has been shifted up 1, the new range of the function is all numbers greater than 1. Since the argument of any log must be greater than 0, (x-1)/2 > 0. Thus x - 1 > 0, so x > 1

Answer:

defines the set of values [ 1, 2, 3, 4, 5 ], and the range

1 : 3 : 5

defines the set of values [ 1, 4 ].

Although a range constant specifies a row vector, Octave does not normally convert range constants to vectors unless it is necessary to do so. This allows you to write a constant like 1 : 10000 without using 80,000 bytes of storage on a typical 32-bit workstation.

A common example of when it does become necessary to convert ranges into vectors occurs when they appear within a vector (i.e., inside square brackets). For instance, whereas

x = 0 : 0.1 : 1;

defines x to be a variable of type range and occupies 24 bytes of memory, the expression

dani uses cotton balls to make snow men for an art project. dani has 14 cotton balls, and she uses 3 cotton balls to make each snow man.dani makes as many as she can.how many snowmen does dani make

Answers

Using the appropriate arithmetic operation, the number of snowmen Danny makes is 4

Total number of cotton balls = 14

Number of cotton balls per snowmen = 3

Creating a proportional relationship thus :

3 cotton = 1 snowman

14 cotton balls = x

Cross multiply

3x = 14

Divide both sides by 3

3x/3 = 14/3

x = 4.667

Hence, the number of snowmen that can be made is 4

A tournament has 187 athletes. There are 91 more girls than boys. Let X represent the number of girls and let Y represent the number of boys. Write the system of equations that represents this situation

Answers

Answer: Need more info

Step-by-step explanation:

The system of equations that represents this situation will be;

⇒ 2Y + 91 = 187

What is linear expression?

A linear expression is an algebraic expression where each term is either a constant or a variable raised to the first power.

Given that;

Total athletes in a tournament = 187

And, In a tournament 91 more girls than the boys.

Now,

Let X represents the number of girls.

Let Y represents the number of boys.

Since, There are 91 more girls than the boys.

So, We can formulate;

X = 91 + Y

And, There are 187 athletes in a tournament.

So, We can formulate;

X + Y = 187

Substitute X = 91 + Y in above equation as;

91 + Y + Y = 187

91 + 2Y = 187

Thus, The system of equations that represents this situation will be;

⇒ 2Y + 91 = 187
