A test for syphilis gives a positive result with probability 0.98 when tested on a person who has the disease. The test gives a negative result with probability 0.9 when tested on a person who does not have the disease. Assume that 3% of a society has the disease, and compute the following probabilities in the order they are asked. Note that for each individual there are two disease status(disease, no disease) and two types of test results(positive, negative). (a) (0.5 point) Compute the probability that an individual has the disease and has a positive test result. Explain your computation. (b) (0.5 point) Compute the probability
Answer:
The probability that an individual has the disease and has a positive test result is:
9.8%.
Step-by-step explanation:
Probability of a true positive result for a test of syphilis = 0.98 or 98%
Probability of a false negative result for a test of syphilis = 0.02 or 2% (100 - 98)
Probability of a true negative result for a test of syphilis = 0.9 or 90%
Probability of a false negative result for a test of syphilis = 0.1 or 10% (100 - 90)
Therefore, the probability that an individual has the disease and has a positive test result = 0.98 * 0.1 = 0.098 = 9.8%

identify the slope and y-intercept of the function y=-5x+4 (brainlyest to correct answer)
Answer: A. The slope is -5, and the y-intercept is (0,4)
Step-by-step explanation:
In standard form, a function is written as y = mx + b, where m = slope and b = the y-intercept
With that in mind, the m value is -5 and the b value is 4
Thus, the slope is -5, and the y-intercept is (0,4)

What is the equation of the line in point-slope form?
Answer:
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Determine the equation in point slope form
From the graph, we have the following points;
[tex](x_1,y_1) = (-400,-400)[/tex]
[tex](x_2,y_2) = (100,-500)[/tex]
First, we calculate the slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-500 - (-400)}{100- (-400)}[/tex]
[tex]m = \frac{-500 +400}{100+400}[/tex]
[tex]m = \frac{-100}{500}[/tex]
[tex]m = -\frac{1}{5}[/tex]
The equation is then calculated using:
[tex]y - y_2 = m(x - x_2)[/tex]
Substitute x and y values
[tex]y - (-500) = -\frac{1}{5}(x - (100))[/tex]
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]

A number minus 14 is more than 35
Answer:
False, -14 is less that 35
Step-by-step explanation:
Answer:
x-14>35
Step-by-step explanation:
x-14>35
1. Replace "A number " with x
x minus 14 is more than 35
Minus = subtraction
x-14 is more than 35
Is more than translates to the inequality >
x-14>35

What is the height, h, of the triangular prism?
Round your answer to the nearest tenth.
Answer:
x = 3 unitsStep-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = h
b = 8/2 = 4
c = 5
plugin values into the formula:
h² + 4² = 5²
h² = 5² - 4²
x = √9
x = 3
Tammi deposited $520 into a bank account that earned simple interest each year. After 5 years, she had earned $156 in interest.
No money was deposited into or withdrawn from the account.
What was the annual interest rate?
Enter your answer in the box.
Answer:
6%
Step-by-step explanation:
Interest = Principal * rate * time
156 = 520(r)(5)
156 = 2600r
r = 0.06 or 6%
Answer:
6 percent
Step-by-step explanation:
Interest =1 Part
156 = 520(annual rate )(5)
156 = 2600(annual interest rate )
annual rate=156/2600
annual interest rate = 0.06
annual interest rate=0.06*100
annual interest rate =6%
