0.0323 is the probability that it is a false negative​ (the test indicates the person does not have the disease when in fact they​ do)

It is a branch of mathematics that deals with the occurrence of a random event.

Let A be the event of “Negative Test Result” and B be the event of “subject has the disease”. Now,

the total  of results is 120+4+172+13=309

Subject has the disease=120+4=124

P(A and B)=4/309

P(B)=124/309

P(negative test result | subject has the disease)

P(A | B) =P(A and B) / P(B)

=(4 / 309) / (124 / 309)

=4 / 124

=1 / 31

0.0323.

Hence 0.0323 is the probability that it is a false negative​ (the test indicates the person does not have the disease when in fact they​ do)

Answer:

-x

Step-by-step explanation:

Simplifying

5x + 2 = 3x

Reorder the terms:

2 + 5x = 3x

Solving

2 + 5x = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

2 + 5x + -3x = 3x + -3x

Combine like terms: 5x + -3x = 2x

2 + 2x = 3x + -3x

Combine like terms: 3x + -3x = 0

2 + 2x = 0

Add '-2' to each side of the equation.

2 + -2 + 2x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + 2x = 0 + -2

2x = 0 + -2

Combine like terms: 0 + -2 = -2

2x = -2

Divide each side by '2'.

x = -1

Simplifying

x = -1

= -x

Answer:

i dont know if you want me to solve for m

Step-by-step explanation:

Let's solve for m.

If you work for the company for 5 years, you will earn approximately $44,925.

To calculate the total earnings after working for the company for 5 years with a 3% raise each year, we need to determine the salary for each year and then sum them up.

In the first year, you will earn $38,900. For subsequent years, you will receive a 3% raise on the previous year's salary. This means that each year's salary will be the previous year's salary multiplied by 1.03.

Year 1: $38,900

Year 2: $38,900 × 1.03 = $40,067

Year 3: $40,067 × 1.03 = $41,270.01 (rounded to the nearest dollar: $41,270)

Year 4: $41,270 × 1.03 = $42,504.10 (rounded to the nearest dollar: $42,504)

Year 5: $42,504 × 1.03 = $43,771.12 (rounded to the nearest dollar: $43,771)

To calculate the total earnings, we add up the salaries for each year:

Total earnings = Year 1 salary + Year 2 salary + Year 3 salary + Year 4 salary + Year 5 salary

Total earnings = $38,900 + $40,067 + $41,270 + $42,504 + $43,771

Total earnings ≈ $206,512

Therefore, if you work for the company for 5 years, you will earn approximately $206,512. Rounded to the nearest dollar, this is approximately $44,925.

To find:

The effect on f(x).

Solution:

Transformation is defined as:

\(g(x)=f(kx)\)            ...(i)

Where, k is the factor of horizontal stretch and compression.

If 0<k<1, then the graph of f(x) stretched horizontally by factor \(\dfrac{1}{k}\).

If k>1, then the graph of f(x) compressed horizontally by factor \(\dfrac{1}{k}\).

It is given that

Example:

Aaron's P.E. class is completing a unit on bowling. So every Friday afternoon for the last three weeks, they have bowled one game at a nearby bowling alley. His scores have been 121, 147, and 96. What would he have to bowl next time in order to have a mean score of 128?

Solution:

Let x represent Aaron's fourth and unknown score. To have a mean of 128, the sum of the four scores would have to be divided by 4. To get that sum by itself, multiply it by 4. You also have to multiply the desired mean of 128 by 4. So the sum of the four scores is equal to 128 times 4.

121 + 147 + 96 + x = 128 ∙ 4

• Substitute in the values of the four scores.

364 + x = 512

• Simplify.

364 - 364 + x = 512 - 364

• Subtract 364 from each side of the equation.

x = 148

• Simplify.

Aaron must score a 148 in order to have a mean score of 128.

Step-by-step explanation:

The result of 20 · 34 is 680, and the result of 20 ÷ 34 is approximately 0.588235294117647. Therefore, 20 · 34 is greater than 20 ÷ 34.The symbol "·" is used for multiplication, and the symbol "÷" is used for division. When we multiply 20 and 34, we are finding the total value of 20 items that are each worth 34. While when we divide 20 by 34, we are finding out how many times 34 can fit into 20, which is less than one.In short, Multiplication gives a bigger value than division, that's why 20*34 is greater than 20/34.

Answer:

Step-by-step explanation:

Hello! The way you can figure this question out is by solving each one.  Let's start with 20 x 34.

How you can multiply 20 x 34

     34
   x20
______
     00 - 0 x 4, 0 x 3 both equal 0
+  680 - Put a 0 to the right of the number, 2 x 4 = 8, 3 x 2 = 6
______
680

34 x 20 = 680

Now, divide 20 by 34

20/34 = 10/17  

10/17 is less than 1, while 680 is much greater than 1.  

680 > 10/17

20 x 34 is greater than 20 divided by 34

Fun fact:
If two numbers are greater than 1, are whole numbers, and they are multiplied and divided, the number produced by each equation will always be greater when multiplied.  

The Probability Density Function (PDF) for a uniform distribution ranging between 3 and 5 is 0.5. Answer is option C.

In a uniform distribution, the probability of a random variable taking any value between the two endpoints of the interval is constant. The probability density function (PDF) of a uniform distribution is a constant value over the range of possible values, and is 0 outside that range. In this case, the PDF for the uniform distribution ranging between 3 and 5 is 0.5, which means that the probability of the random variable taking any value between 3 and 5 is the same, and is equal to 0.5.

The PDF being a constant value of 0.5 implies that the distribution is symmetric, with equal probability of the random variable taking any value between the two endpoints. Thus, option C is answer.

Answer:

If Thabang worked for three hours and Ndivhu worked for two hours, then the total number of hours worked is five. To determine the amount Thabang will receive if they decided to share their money according to hours, we need to calculate the proportion of the total hours that Thabang worked and multiply that by the total amount of money earned.

Thabang worked for three out of five hours, which is 3/5 or 0.6 of the total time. To find out how much money he should receive, we can multiply this fraction by the total amount earned:

0.6 x R400 = R240

Therefore, Thabang should receive R240 if they decide to split the money based on hours worked.

Step-by-step explanation:

Given that :

Principal = 5000 ; interest rate (r) = 6% = 0.06 ; interest periods (n) = 4 ; number of years (t) = 12

The compound interest formula:

A = P(1 + r/n)^nt

Investment compounded periodically :

A = 5000(1 + 0.06/4)^(4 * 12)

A = 5000(1.015)^48

A = 5000(2.0434782)

A = 10217.391

Investment compounded annually :

A = P(1 + r/n)^nt

A = 5000(1 + 0.06)^12

A = 5000(1.06)^12

A = 5000(2.012196471835550329409536)

A = 10060.98235917775164704768

The probability of choosing a 't' or an 'e' from the word 'committee' = 4/9

We know that the formula for the probability of an event is given by,

P = number of favourable outcomes / total number of possible outcomes of an event

Let us assume that event A : choosing a letter 't'  from the word 'committee'

and event B: choosing a letter 'e' from the word 'committee'

Here, sample space is the number of letters in the the word 'committee'

So, n(S) = 9

We know that there are two 't' letters in the the word 'committee'

So, n(A) = 2

And there are 2 'e'  letters in the the word 'committee'

So, n(B) = 2

To find the required probability, the number of favourable outcomes

= 2 + 2

= 4

So, the required probability would be:

P = 4/9​

To find the maximum volume of a cylinder inscribed in a sphere of radius r, we need to use optimization techniques. The cylinder should be such that its height is equal to its diameter and both should be equal to the diameter of the sphere. This means that the cylinder should be a cube with its diagonal equal to the diameter of the sphere.

Let the diameter of the sphere be 2r. The diagonal of the cube is equal to the diameter of the sphere, so its side is r√3. The volume of the cube is (r√3)^3 = 27r^3.

Since the cylinder is inscribed in the sphere, its radius is r and its height is 2r. The volume of the cylinder is πr^2(2r) = 2πr^3.

To maximize the volume of the cylinder, we need to differentiate the volume equation with respect to r and set it equal to zero:

d/dx (2πr^3) = 6πr^2 = 0

This gives us r = 0, which is not a valid solution. Therefore, the maximum volume of the cylinder inscribed in the sphere of radius r is 2πr^3, when the cylinder is a cube with its diagonal equal to the diameter of the sphere.

The simplified expression using De Morgan's law are  a)x'y'z'u  b)x'y'u c): x'y'u and d)x'y'z'+xy'z'+xyz.

The main idea is to simplify each Boolean expression by repeatedly applying De Morgan's law until each complement operation operates on a single variable.

Then, apply the double complement law to simplify the expression further. In the end, the simplified expression should contain only AND and OR operations without any complement operators acting on multiple variables.

a. 1/ x + yz + u can be simplified using De Morgan's law to: (x'y'z')u'. Then, applying the double complement law, we get the simplified expression as: x'y'z'u.

b. 1/x(y + 2)u can be simplified using De Morgan's law to: x'(y'+2')u'. Then, applying the double complement law, we get the simplified expression as: x'y'u.

c. 1/(x + y)(uv + xy) can be simplified using De Morgan's law to: (x'y')(u' + x'y'). Then, applying the double complement law, we get the simplified expression as: x'y'u.

d. 1/xy + yz + xz can be simplified using De Morgan's law to: (x'+y')(y'+z')(x'+z'). Then, applying the double complement law, we get the simplified expression as: x'y'z'+xy'z'+xyz.

In summary, to simplify Boolean expressions, we can apply De Morgan's law repeatedly and then use the double complement law to remove complement operators acting on a single variable twice.

Freud is a stage theorist. Sigmund Freud, the renowned Austrian neurologist and psychoanalyst, is widely recognized as one of the pioneers in the field of psychoanalysis.

He proposed a developmental theory that included psychosexual stages of development. According to Freud, human development progresses through distinct stages, each characterized by a specific focus on different erogenous zones. These stages include the oral stage, stage, phallic stage, latency stage, and genital stage. Freud believed that the way individuals navigate these stages influences their personality and psychological well-being in adulthood.

Although Freud's stage theory has been critiqued and modified over time, his ideas regarding the importance of early childhood experiences and unconscious processes have had a profound impact on psychology and continue to shape our understanding of human development.
