A recent study has shown that 10% of computer science concentrators suffer from symptoms of Carpal Tunnel Syndrome. Researchers have developed a diagnostic test for this condition and in a recent trial, the test gave a positive result in 96% of the patients who were known to truly have Carpal Tunnel Syndrome.
a) For an initial version of the diagnostic test, the false positive rate (the percentage of people without Carpal Tunnel who incorrectly test positive) was 44%. If a student received a positive result from this test, what would be the posterior probability that they truly have Carpal Tunnel Syndrome?
b) The researchers believe their test will be practically useful if a positive result implies the student has Carpal Tunnel with at least 75% probability. What is the largest possible false positive rate that would achieve this accuracy target?

Answers

Answer 1

Answer:

1. 0.1951

2. 3.56%

Step-by-step explanation:

Probability of disease = 0.10

Probability of disease and positive = 0.96

1.

Probability of no disease and positive = 0.44

Probability of disease and positive result = 0.10x0.96/0.10x0.96+0.90x0.44

= 0.096/0.096+0.396

= 0.096/0.492

= 0.1951

2.

Probability of disease false positive result

P(disease|positive result)

= (0.10x0.96/0.10x0.96+0.90xP) >= 0.75

= 0.096/0.096+0.90p >= 0.75

We cross multiply

0.096 >= 0.75(0.096+0.90p)

0.096 >= 0.072 + 0.675p

0.096-0.072 >= 0.675p

0.024 >= 0.675p

P <= 0.03555

Therefore the largest possible false positive rate = 0.0356

= 3.56%

what is 3(x – 6) = -12x - 9

Answers

Answer:

x = 3/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x−6)=−12x−9

(3)(x)+(3)(−6)=−12x+−9(Distribute)

3x+−18=−12x+−9

3x−18=−12x−9

Step 2: Add 12x to both sides.

3x−18+12x=−12x−9+12x

15x−18=−9

Step 3: Add 18 to both sides.

15x−18+18=−9+18

15x=9

Step 4: Divide both sides by 15

15x/15 = 9/15

  so x = 3/5

Find an autonomous differential equation with all of the following properties:
equilibrium solutions at y=0 and y=3,
y' > 0 for 0 y' < 0 for -inf < y < 0 and 3 < y < inf
dy/dx =

Answers

Answer:

dy/dt = y ( 3 - y )

Step-by-step explanation:

Given data:

Determine an autonomous differential equation with the following properties

y = 0 and Y = 3

y' > 0 for  0 < y < 3

y' < 0 for  -∞ < y < 0  and  3 < y < ∞

considering an autonomous differential equation

dy/dt = y ( 3 - y )

y = 0 and 3 represents equilibrium solutions

if 0 < y < 3  then y ( 3 - y ) > 0  for   0 < y < 3

hence : dy / dt = y' > 0  for 0 < y < 3

y ( 3 - y ) <  0  for -∞ < y < 0 and  3 < y < ∞

hence : dy / dt = y' < 0  for  -∞ < y < 0  and  3 < y < ∞

this shows that the autonomous differential equation satisfies every condition hence the autonomous differential equation is :

dy/dt = y ( 3 - y )

On a coordinate grid, point T is at (2,-4) and point Sis at (2,6). The distance (in units) between points T and Sis
numbers, such as 2.) (5 points)
(Input only whole

Answers

Answer:

The distance 'd' between T and S:

[tex]d=10[/tex]

Step-by-step explanation:

As the point 'T' is located at (2, -4)

So, the point 'T' has the coordinates (2, -4)

And the point 'S' is located at (2, 6)

So, the point 'T' has the coordinates (2, 6)

The distance 'd' between T and S can be computed using the formula:

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

[tex]=\sqrt{\left(2-2\right)^2+\left(6-\left(-4\right)\right)^2}[/tex]

[tex]=\sqrt{\left(2-2\right)^2+\left(6+4\right)^2}[/tex]

[tex]=\sqrt{0+10^2}[/tex]

[tex]=\sqrt{10^2}[/tex]

[tex]d=10[/tex]

Therefore, the distance 'd' between T and S:

a) It takes a groundskeeper 45 minutes to prepare a softball field for a game. It takes his assistant 50 minutes to prepare the same field. How long will it take if they work together to prepare the field?

G does 1/45 job per minute

A does 1/50 job per minute

Together, they do 1/45 + 1/50 = 19/450 jobs/minute

--> 450/19 minutes to do the job

You can use a shortcut, product/sum

50*45/(50+45) = 2250/95

= 450/19

At a dinner party, two desserts are being served. Six of the guests choose cheesecake, and eight of the guests choose apple pie. Write two associated part-to-whole ratios for this situation, in simplest form. Then, interpret these ratios within the situation.​

Answers

Answer:

6 to 2 2 to 6

Step-by-step explanation:

The ratios for the given situation are 3/7 and 4/7.

Given that, at a dinner party, two desserts are being served.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Six of the guests choose cheesecake, and eight of the guests choose apple pie.

So, the total number of guests = 6+8

= 14

Now, the ratio who chose cheesecake = 6/14

= 3/7

The ratio who chose apple pie = 8/14

= 4/7

Therefore, the ratios for the given situation are 3/7 and 4/7.

The charity starts the year with one asset, cash of $700,000. Net assets without donor restrictions are $400,000. Net assets with donor restrictions are $300,000. Of the restricted net assets, $160,000 is to be held and used to buy equipment, $40,000 is to be used for salaries, and the remaining $100,000 must be held permanently. The permanently held amount must be invested with 70 percent of any subsequent income used to cover advertising for fundraising purposes. The rest of the income is unrestricted.During the current year, this health care entity has the following transactions:1. Receives unrestricted cash gifts of $210,000.2. Pays salaries of $80,000, with $20,000 of that amount coming from purpose-restricted donated funds. Of the total salaries, 40 percent is for administrative personnel. The remainder is divided evenly among individuals working on research to cure the disease and individuals employed for fundraising purposes.3. Buys equipment for $300,000 by signing a long-term note for $250,000 and using restricted funds for the remainder. Of this equipment, 80 percent is used in research. The remainder is split evenly between administrative activities and fundraising. The donor of the restricted funds made no stipulation about the reporting of the equipment purchase.4. Collects membership dues of $30,000 in cash. Members receive a reasonable amount of value in exchange for these dues including a monthly newsletter that describes research activities. By the end of the year, 112/112 of this money had been earned.5. Receives $10,000 in cash from a donor. The money must be conveyed to a separate charity doing work on a related disease.6. Receives investment income of $13,000 from the permanently restricted net assets.Pays $2,000 for advertising. The money comes from the income earned in (f).Receives an unrestricted pledge of $100,000 that will be collected in three years. The entity expects to collect the entire amount. The pledge has a present value of $78,000. Related interest (considered contribution revenue) of $5,000 is earned prior to the end of the year.7. Computes depreciation on the equipment bought in (c) as $20,000.8. Spends $93,000 on research supplies that are used up during the year.9. Owes salaries of $5,000 at the end of the year.
