suppose that, of women who undergo routine screening, 1/101 have breast cancer. of the women who undergo screening and do have breast cancer, 80% will have a positive test. of the women who undergo screening but don't have breast cancer, only 5% have a positive test. a woman of this age undergoes routine screening and has a positive test. what is the probability that she has breast cancer? give your answer as a numerical value between 0 and 1, to three decimal places. (do not give it as odds, a fraction, or a percentage!)

Answers

Answer 1

Answer:

The probability that she has breast cancer if she gives a positive test result is P=0.16

Step-by-step explanation:

And according to the Bayes theorem I got 0.16

Answer 2

The probability that the woman who underwent routine screening and has a positive test has breast cancer is 0.017.

Let A denote the event that the woman has breast cancer, and let B denote the event that she has a positive test result. Then we need to find P(A|B), the probability that A occurs given that B has occurred. By Bayes' theorem, we have:

P(A|B) = P(B|A)P(A) / [P(B|A)P(A) + P(B|not A)P(not A)]

where P(not A) = 1 - P(A) is the probability that the woman does not have breast cancer.

From the problem statement, we have:

P(A) = 1/101, P(B|A) = 0.8, and P(B|not A) = 0.05.

Therefore,

P(not A) = 100/101,

and

P(A|B) = (0.8 x 1/101) / [(0.8 x 1/101) + (0.05 x 100/101)] = 0.017 (to three decimal places).

Therefore, the probability that the woman who underwent routine screening and has a positive test has breast cancer is 0.017.

In mathematics, a functiοn frοm a set X tο a set Y assigns each element οf X exactly οne element οf Y. The sets X and Y are referred tο as the functiοn's dοmain and cοdοmain, respectively.

Initially, functiοns represented the idealized relatiοnship between varied quantities and οther variables. Fοr instance, time affects a planet's pοsitiοn.

Answers

Assuming the coordinates of point A are (3, 5): we would have the following results.

What is the explanation for the above response?

1. To reflect over the x-axis: the x-coordinate remains the same and the y-coordinate changes sign. So point B will have the same x-coordinate as point A (3), but the y-coordinate will be -5. Therefore, the coordinates of point B are (3, -5).

2. To reflect over the y-axis: the y-coordinate remains the same and the x-coordinate changes sign. So point C will have the same y-coordinate as point A (5), but the x-coordinate will be -3. Therefore, the coordinates of point C are (-3, 5).

3. To translate: add the given values to the x and y coordinates. So point D will have an x-coordinate of 3 + 3 = 6, and a y-coordinate of 5 + 4 = 9. Therefore, the coordinates of point D are (6, 9).

4. To rotate 180 degrees clockwise: flip the signs of both the x and y coordinates and then swap them. So point E will have an x-coordinate of -5 and a y-coordinate of -3. Therefore, the coordinates of point E are (-5, -3).

Plotting these points on a graph,
A (3, 5)

B  (3, -5)

C  (-3, 5)

D (6, 9)

A right triangle with an angle of approximately 53.1° is inscribed in the first quadrant of the unit circle, with a horizontal length of 3/5 and a vertical length of 4/5.

Answers

The length 53.1°, 90°, and 39.9°,vertical length: 3/5 ,length of vertical: 4/5 1 hypotenuse.

What is angle?

Angle is a geometric concept that describes the relative difference between two straight lines or planes that meet at a common point. It is measured in degrees, radians or grads, and is often represented by the symbol θ. An angle can be acute, right, obtuse, straight, reflex, or full. Angles can be used to measure the size of a triangle, to calculate the area of a figure, and to determine the position of a point in a coordinate system.

We possess that

Angle = 53.1°

Vertical length = 3/5 (this is the adjacent cathetus)

Vertical length equals 4/5 (this is the opposite cathetus)

We can use it to check this.

tg(angle) = adjacent/opposite:

tg(53.1) = 1.33

and

(4/5)/(3/5) = 4/3 = 1.33

This makes sense, then.

Using the relationship, we can now identify the hypotenuse:

Sin(angle) = the antipode or hypotenuse

sin(53.1) = (4/5)/H

H = (4/5)/sin(53.1) = 1

Hence, there is always a 90° angle in a triangle or rectangle.

We may get the final angle using the fact that the sum of a triangle rectangle's three interior angles is always 180 degrees.

A + 53.1° + 90° = 180°

A = 90° - 53.1° = 36.9°

Answers

The cost of 1800 bricks is $7,386.76. The cost of 1800 bricks, each measuring 7 1/4 in by 21 1/4 in by 3 1/4 in and weighing 0.06 ounces per cubic inch, can be calculated as follows:

First, we need to find the volume of one brick by multiplying its three dimensions:

Volume of one brick = 7.25 in x 21.25 in x 3.25 in = 526.0156 cubic inches

Next, we can find the weight of one brick by multiplying its volume by its weight per cubic inch:

Weight of one brick = 526.0156 cubic inches x 0.06 ounces/cubic inch = 31.56094 ounces

The total weight of 1800 bricks can be found by multiplying the weight of one brick by 1800:

Total weight of 1800 bricks = 31.56094 ounces/brick x 1800 bricks = 56,809.6928 ounces

Finally, we can find the cost of the bricks by multiplying their total weight by the cost per ounce:

Answers

The probability that a randomly selected part is not defective is 47/50.

What is probability?

Probability is a way of calculating how likely something is to happen. It is difficult to provide a complete prediction for many events. Using it, we can only forecast the probability, or likelihood, of an event occurring. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

Here Total number of parts machine makes = 50

Number of parts defective out of 50 = 3

Then number of parts not defective out of 50 = 50-3 = 47.

Now using probability formula:

Probability = No of favorable item/ Total no of item

(co 1) in a normally distributed data set with a mean of 22 and a standard deviation of 4.1, what percentage of the data would be between 13.8 and 30.2? g

Answers

The percentage of data between 13.8 and 30.2 in a normally distributed data set with a mean of 22 and a standard deviation of 4.1 is approximately 94.19%.

To solve this problem, we can first standardize the values of interest using the standard normal distribution formula, z = (x - μ) / σ, where x is the value of interest, μ is the mean, and σ is the standard deviation.

For the lower value of 13.8, we have z = (13.8 - 22) / 4.1 = -1.95. For the upper value of 30.2, we have z = (30.2 - 22) / 4.1 = 2.05.

Next, we can use a calculator to find the area between these two z-scores. Alternatively, we can use the complement rule to find the area to the left of -1.95 and the area to the right of 2.05, and subtract their sum from 1.

Using a calculator, we find that the area between -1.95 and 2.05 is approximately 0.9419 or 94.19%. Therefore, approximately 94.19% of the data falls between 13.8 and 30.2 in this normally distributed data set.

Answers

The sum of the arithmetic series of 28 + 28.4 ...+ 42 is 1260.

What is arithmetic series?

An arithmetic series is a sequence of numbers in which each term is obtained by adding a constant difference, called the common difference, to the preceding term.

According to question:

To resolve this issue, we can utilise the following formula for the sum of an arithmetic series:

S = (n/2) * (a₁ + aₙ)

When n is the number of terms, a1 is the first term, and an is the nth term, S is the series total.

To find the number of terms, we need to figure out the pattern of the series. The common difference (d) is expressed as follows:

d = 28.4 - 28 = 0.4

To get from 28 to 42, we need to add (42 - 28)/0.4 = 35 terms.

So the number of terms is:

n = 35 + 1 = 36

The first term is a₁ = 28, and the last term is aₙ = 42.

Now we can plug these values into the formula:

S = (n/2) * (a₁ + aₙ)

= (36/2) * (28 + 42)

= 18 * 70

= 1260

Therefore, the sum of the arithmetic series is 1260.

distance run = 8 km/h x (t/60) h = (8t/60) km

Total distance = distance walked + distance run = 8 km + (8t/60) km = (480 + 8t) / 60 km

Now, let's find the total time:

total time = time walked + time run

time walked = distance ÷ speed = 8 km ÷ 4 km/h = 2 h

time run = t/60 h

total time = 2 h + t/60 h = (120 + t)/60 h

Now we can substitute the values we have found into the formula for average speed:

5 km/h = [(480 + 8t)/60 km] ÷ [(120 + t)/60 h]

Simplifying the right-hand side, we get:

5 km/h = (480 + 8t) / (120 + t)

Multiplying both sides by (120 + t), we get:

600 + 5t = 480 + 8t

Subtracting 480 and 5t from both sides, we get:

120 = 3t

Therefore, Ann has to run for (120/3) = 40 minutes to have an average speed of 5 km/h over her complete journey.

Expand using the Product property...In 2xy

Answers

As a result, the product property can be used to manipulate and equation statements containing 2xy, as well as to express 2xy in terms of its factors.

What is equation?

An equation is a statement that shows the equality between two mathematical expressions. It is a fundamental concept in mathematics and is used to describe relationships between quantities.

The purpose of an equation is to find the value of the unknown variable(s) that make the equation true. This is typically done by applying algebraic operations to manipulate the equation, with the goal of isolating the variable on one side of the equal sign.

[tex]2xy = 2 * x * y[/tex]

[tex]2xy = 2x * y = 2y * x = x * 2y = y * 2x = x * y * 2[/tex]

[tex]4x^2y * 3xy^2 = (4 * x * x * y) * (3 * x * y * y)[/tex]

[tex]= 12 * x^3 * y^3[/tex]

As a result, the product property can be used to manipulate and simplify statements containing 2xy, as well as to express 2xy in terms of its factors.

an acme bearings manager wants to compare the average ball bearing sizes from two different machines. she suspects the mean diameter for bearings from machine 2 exceeds that of bearings from machine 1. she takes two independent, random samples of size 50, one from each machine. the mean and standard deviation of bearings taken from machine 1 are 3.302 mm and 0.051 mm. the mean and standard deviation of bearings taken from machine 2 are 3.355 mm and 0.050 mm. run a hypothesis test consistent with her suspicions. be sure to a. check all necessary assumptions; b. state the null and alternative hypotheses; c. decide whether or not to pool and explain why; d. calculate the test statistic and p-value; e. state your conclusion in a complete sentence based on the p-value.

Answers

a. The necessary assumptions are the population variances are equal and combine the two sample variances into one.

b. The null and alternative hypotheses are defined.

c. The sample sizes are equal, and the sample standard deviations are approximately equal, we can safely assume equal variances and pool the sample variances.

d. The value of test statistic is 3.15 and p value is 0.05.

e. The mean diameter of bearings from machine 2 is greater than that of machine 1 at a 5% level of significance.

To begin the hypothesis test, the manager needs to state the null and alternative hypotheses. The null hypothesis (H0) is the statement of "no difference" between the mean diameters of bearings from the two machines. The alternative hypothesis (Ha) is the statement that the mean diameter of bearings from machine 2 is greater than that of machine 1.

In symbols,

H0: μ1 = μ2 (where μ1 is the mean diameter of machine 1 and μ2 is the mean diameter of machine 2) and

Ha: μ2 > μ1.

Before conducting the hypothesis test, we need to check some assumptions.

The next step is to calculate the test statistic and p-value. We use a t-test to compare the means of two independent samples. The test statistic is calculated as:

t = (x₁ - x₂) / [s_p x √(2/n)]

where x₁ and x₂ are the sample means, s_p is the pooled standard deviation, and n is the sample size.

Plugging in the numbers, we get:

t = (3.355 - 3.302) / [0.050 x √(2/50)] = 3.15

Using a t-distribution table with 98 degrees of freedom (n₁ + n₂-2), we find that the p-value associated with a t-value of 3.15 is less than 0.01.

Finally, we need to state our conclusion based on the p-value. Since the p-value is less than our significance level of 0.05, we reject the null hypothesis.

Wnte an equation in slope-intercept form of the line that passes through (-3, 2) and (-2, - 5).

WILL GIVE BRAINLIEST

Answers

An equation in slope-intercept form of the line that passes through (-3, 2) and (-2, - 5) is: C. y = -7x - 19.

How to determine an equation of this line?

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation:

y - y₁ = m(x - x₁)

Where:

m represent the slope.x and y represent the points.

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-5 - 2)/(-2 + 3)

Slope (m) = -7/1

Slope (m) = -7

At data point (-3, 2), a linear equation in slope-intercept form for this line can be calculated as follows:

y - y₁ = m(x - x₁)

y - 2 = -7(x + 3)

y = -7x - 21 + 2

y = -7x - 19

Carson's favorite store is having a sale. All clothing is 40% off, and Carson has a coupon for another $10 off his purchase. He buys a sweater for $65.99. How much does Carson pay for the sweater after the discounts?

Answers

Answer:

First, we can calculate the discount from the sale. The sweater costs $65.99, and with a 40% discount, the price is reduced by:

$65.99 x 0.40 = $26.40

So the sale price of the sweater is:

$65.99 - $26.40 = $39.59

Next, we can apply Carson's $10 coupon to the sale price:

$39.59 - $10 = $29.59

Therefore, Carson pays $29.59 for the sweater after the discounts.

To calculate the total discount that Carson receives, we can first find the amount of the 40% discount on the sweater, which is:

40% of $65.99 = 0.4 x $65.99 = $26.40

Then, we can add the additional $10 coupon discount to get the total discount:

$26.40 + $10 = $36.40

Therefore, the total discount that Carson receives on the sweater is $36.40.

To find the final price that Carson pays after the discounts, we can subtract the total discount from the original price:

$65.99 - $36.40 = $29.59

Therefore, Carson pays $29.59 for the sweater after the discounts.
