A certain disease has an incidence rate of 0.4%. If the false negative rate is 8% and the false positive rate is 2%, compute the probability that a person who tests positive actually has the disease

Answers

Answer:

To compute the probability that a person who tests positive actually has the disease, we need to use Bayes' theorem:

P(D|P) = P(P|D) * P(D) / P(P)

where:

P(D|P) is the probability of having the disease given a positive test result

P(P|D) is the probability of testing positive given that the person has the disease (also known as sensitivity), which is 1 - false negative rate = 0.92 in this case

P(D) is the incidence rate of the disease, which is 0.4% = 0.004

P(P) is the probability of testing positive, which can be computed using the false positive rate as 1 - specificity = 1 - 0.98 = 0.02

Plugging in the values, we get:

P(D|P) = 0.92 * 0.004 / 0.02 = 0.184

Therefore, the probability that a person who tests positive actually has the disease is 0.184, or about 18.4%.

The solution of the linear equation y =  15 x + 9 and y = 1/2 x - 20 is

x = -2

y = -21

How to solve the linear equation

The linear equation can be solved by graphical method to give the solution. The graph is attached

(-2, 21)

Using elimination method we have

y =  15 x + 9

y = 1/2 x - 20

subtracting will result to

0 = 14.5x + 29

-14.5x = 29

isolating x

x = 29 / -14.5

x = -2

substituting x = -2 into y =  15 x + 9

y =  15 (-2) + 9

y = -30 + 9

y = -21

Hence the solution is x = -2 and y = -21

Suppose that a company wishes to predict sales volume based on the amount of advertising expenditures. The sales manager thinks that sales volume and advertising expenditures are modeled according to the following linear equation. Both sales volume and advertising expenditures are in thousands of dollars.

Estimated Sales Volume=45.15+0.54(Advertising Expenditures)

If the company has a target sales volume of $125,000
, how much should the sales manager allocate for advertising in the budget? Round your answer to the nearest dollar.

Answers

Answer:

We can use the given equation to solve for the advertising expenditures needed to achieve the target sales volume of $125,000:

125 = 45.15 + 0.54x

where x is the advertising expenditures in thousands of dollars.

Simplifying the equation:

0.54x = 125 - 45.15

0.54x = 79.85

x = 79.85 / 0.54

x ≈ 147.69

Therefore, the sales manager should allocate about $147,690 for advertising in the budget to achieve the target sales volume of $125,000.

You go into a car dealership and tell them that you have a budget of $300/month. You are interested in getting a Chevy Cruze that is on sale for $16,000. Due to your excellent credit score, you qualify for a 5-year loan at 4% APR with No Down Payment. What is your monthly payment? Are you within budget?

how much will the car cost you after the loan has been paid in full?​

Answers

Answer: $17,788.20

Step-by-step explanation:

To calculate the monthly payment, we can use the loan formula:

P = (r * A) / (1 - (1 + r)^(-n))

where:

P is the monthly payment

A is the loan amount, which is the sale price of the car ($16,000) in this case

r is the monthly interest rate, which is the annual percentage rate (APR) divided by 12 (4% / 12 = 0.003333...)

n is the total number of payments, which is the number of years of the loan multiplied by 12 (5 years * 12 = 60)

Substituting these values into the formula, we get:

P = (0.003333... * $16,000) / (1 - (1 + 0.003333...)^(-60))

P ≈ $296.47

Therefore, the monthly payment is approximately $296.47, which is within the budget of $300/month.

To calculate the total cost of the car after the loan has been paid in full, we can multiply the monthly payment by the total number of payments (60) and add the original sale price of the car:

Total cost = P * n + A

Total cost = $296.47 * 60 + $16,000

Total cost = $17,788.20

Therefore, the total cost of the car after the loan has been paid in full is approximately $17,788.20.

In the U.S, individuals who earn an income in the top 1 percent can be referred to as good earners The percent of top earners who are men, , is more than four and a half times the percent of top earners who are women, . Also the percent of top earners who are men, , is less than five times the percent of top earners who are women, . Write and solve a compound inequality for the top percent of earners who are women:W.

Answers

Answer:1.111

Step-by-step explanation:

Let's use the variable W to represent the percent of top earners who are women.

According to the problem statement, the percent of top earners who are men is more than four and a half times the percent of top earners who are women. Mathematically, we can write this as:

M > 4.5W

Additionally, the percent of top earners who are men is less than five times the percent of top earners who are women. This can be written as:

M < 5W

We can combine these two inequalities into a compound inequality:

4.5W < M < 5W

This means that the percent of top earners who are men is between 4.5 times and 5 times the percent of top earners who are women.

To solve for W, we can divide all three parts of the compound inequality by 4.5:

W < M/4.5 < W/0.9

Simplifying, we get:

W < 0.222M < 1.111W

Therefore, the percent of top earners who are women, W, must be less than 0.222 times the percent of top earners who are men, and also less than 1.111 times the percent of top earners who are women.

What is probability?

Calculating the chance that an event will occur or a statement will be true is the subject of probability theory, a branch of mathematics. A risk is a number between 0 and 1, where 1 denotes certainty and a probability of about 0 denotes the likelihood that an event will occur. The likelihood that an event will take place is mathematically expressed as probability. Probabilities can also be expressed as percentages ranging from 0% to 100% or as integers between 0 and 1. the proportion of equally plausible possibilities that actually happen in relation to all possible outcomes when a certain event occurs.

The sample mean's sampling distribution may be approximated using the central limit theorem as having a mean of 425 and a standard deviation of[tex]80\sqrt(50) = 11.31.[/tex]

z is equal to (x - mu) / (sigma / sqrt(n))

where n is the sample size, x is the sample mean, mu is the population mean, sigma is the population standard deviation.

When we enter the values, we obtain:

How to explain the histogram

A histogram with a longer right tail indicates that the data is skewed to the right, which means that the majority of the data points are on the left side of the graph, and there are fewer data points on the right side. This is also known as a positively skewed distribution.

In a positively skewed distribution, the mean is typically greater than the median, and the mode is less than the median. This is because the presence of outliers on the right side of the graph can pull the mean towards higher values, while the median remains closer to the bulk of the data.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The problem asks us to construct a boxplot and identify the 5-number summary of a set of data. The data represents the amounts of strontium-90 (in millibecquerels, or mBq) in a sample of baby teeth from residents born after 1979. The data is as follows:

124, 127, 131, 135, 138, 142, 142, 143, 147, 150, 154, 156, 157, 160, 163, 168, 170, 171, 174, 181

To construct the boxplot, we need to first find the 5-number summary, which consists of the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value. We can find these values by putting the data in ascending order and then using the following formulas:

Q1 = median of the lower half of the data

Q2 = median of the entire data set

Q3 = median of the upper half of the data

Using these formulas, we find the 5-number summary to be:

Minimum value: 124 mBq

Q1: 138 mBq

Median: 150 mBq

Q3: 168 mBq

Maximum value: 181 mBq

We can now use this information to construct the boxplot. The horizontal axis represents the values in the data set, and the vertical axis represents the frequency or density of those values. The boxplot consists of a box that extends from Q1 to Q3, with a line segment drawn through the box at the median (Q2). Whiskers extend from the top and bottom of the box to the minimum and maximum values, respectively, unless there are outliers. Outliers are plotted as individual points beyond the whiskers.

Therefore, In this case, the boxplot is option A, which shows the box extending from 130 to 165.5 mBq, with a line segment drawn through the box at 160.75 mBq. The whiskers extend from 114 to 201 mBq, with no outliers.

what is function?

Mathematicians research numbers, their variants, equations, associated structures, forms, and possible configurations of these. The word "function" describes the connection between a group of inputs, each of which has a corresponding output. A function is a connection between inputs and outputs where each input results in a single, distinct outcome. Each function has a domain, codomain, or scope assigned to it. Functions are usually denoted by the letter f. (x). An x is entered. On functions, one-to-one capabilities, so multiple capabilities, in capabilities, and on functions are the four main categories of accessible functions.

The sine function of the form f(x) = -2sin(x) is an amplitude-scaled sine function.

The sine function's amplitude is represented by the coefficient, which in this example is -2. Hence, the function's amplitude is 2.

The equation T = 2/, where is the angular frequency, yields the period of the function. The angular frequency of a sine function is given by = 2/T.

With the function f(x) = -2sin(x) substituted, we get:

ω = 2π/T

Sin(x + ) = -2sin(x)

To solve for T, we obtain:

T = 2π/ω = 2π/(-2) = -π

We use T's absolute value as the period cannot be negative, making the function's period T =.

As a result, the function's amplitude is 2 and its period is.

What is the spread of 2 1 4 3 5 1 1 2 using standard deviation

Answers

The spread of the numbers 2, 1, 4, 3, 5, 1, 1, 2 using standard deviation is approximately 1.768.

We must first determine the mean (average) of the numbers in order to use the standard deviation to determine the spread (i.e., variability) of the set of data.

By adding up all the numbers and dividing by the total number of numbers, the mean is calculated:

mean = (2 + 1 + 4 + 3 + 5 + 1 + 1 + 2) / 8

= 19 / 8

≈ 2.375

The difference between each number and the mean is then determined:

2 - 2.375 = -0.375

1 - 2.375 = -1.375

4 - 2.375 = 1.625

3 - 2.375 = 0.625

5 - 2.375 = 2.625

1 - 2.375 = -1.375

1 - 2.375 = -1.375\s2 - 2.375 = -0.375

Then, each of these discrepancies is squared:

(-0.375)^2 = 0.140625

(-1.375)^2 = 1.890625

(1.625)^2 = 2.640625

(0.625)^2 = 0.390625

(2.625)^2 = 6.890625

(-1.375)^2 = 1.890625

(-1.375)^2 = 1.890625

(-0.375)^2 = 0.140625

The variance is then calculated as the average of these squared differences:

variance is equal to 3.125 x (0.0140625 x 1.890625 x 2.640625 x 0.390625 x 6.890625 x 1.890625 x 0.140625).

Lastly, we calculate the standard deviation by taking the square root of the variance:

(3.125) 1.768 is the standard deviation.

As a result, using standard deviation, the range of the digits 2, 1, 4, 3, 5, 1, 1, 2 is almost 1.768.

c. Is it possible to rearrange the locations of the
4 plates in the original figure so that (1) their
distance from the center of the table does not
change, (2) their centers remain somewhere on the
rectangle design, and (3) the resulting figure has a
rotational symmetry of order 4? If so, draw the
figure. If not, explain why.

Answers

Using the concept of rotational symmetry, the angle of rotation about the center that results in an image that matches the original figure is; Option A:  90

What is rotational symmetry?

Rotational symmetry is defined as a process that requires the rotation of a given object about a reference point to produce its image which has the same characteristics. This tells us that its dimensions, measure of internal angles and size do not change except its orientation. The orientation depicts the way in which the object is positioned.

here, we have,

The sum of an angle formed at a point is 360 degrees.

Thus turning a given object about a point implies its rotation with respect to a measured  angle.

Thus in the diagram given in the question, the pattern shown divides the angle at the centered point into four equal parts.

Thus;

Angle of rotation = 360/4 = 90 degrees

What is Dilation?

Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.

Every dilated image are similar figures to the original figure.

Center of dilation is defined as the point which is fixed on a plane. All the points are dilated about this point.

This can be situated inside or outside the preimage and image.

We can find the position of center of dilation by connecting corresponding vertices of the image and preimage and extend the line up to which all the lines intersect.

The intersecting point is the center of dilation.

Using this concept, here, the center of dilation is inside V.

Hence the center of dilation is located inside the figure V.
