suppose that 8% of the patients tested in a clinic are infected with hiv. furthermore, suppose that when a blood test for hiv is given, 94% of the patients infected with hiv test positive and that 7% of the patients not infected with hiv test positive. what is the probability that

Answers

Answer 1

By using Probability, it can be calculated that

a) Probability that the person test positive for HIV is infected with HIV = 0.54

b) Probability that the person test positive for HIV is not infected with HIV = 0.46

c) Probability that the person test negative for HIV is infected with HIV = 0.0056

d) Probability that the person test negative for HIV is not infected with HIV (P(not HIV|-ve)) = 0.9944

What is Probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

Probability that the person is infected with HIV (P(HIV)) = 0.08

Probability that the person is not infected with HIV (P(not HIV)) = 0.92

Probability that the person infected with HIV test positive (P(+ve|HIV)) = 0.94

Probability that the person infected with HIV test negative (P(-ve|HIV)) = 0.06

Probability that the person not infected with HIV test positive (P(+ve|not HIV)) = 0.07

Probability that the person not  infected with HIV test negative (P(-ve|not HIV)) = 0.93

By using Baye's Theorem of probability,

a) Probability that the person test positive for HIV is infected with HIV (P(HIV|+ve))  =

[tex]\frac{0.94 \times 0.08}{0.94 \times 0.08 + 0.92 \times 0.07}[/tex] = 0.54

b) Probability that the person test positive for HIV is not infected with HIV   (P(no HIV|+ve)) = 1 -  0.54 = 0.46

c) Probability that the person test negative for HIV is infected with HIV (P(HIV|-ve) =

[tex]\frac{0.06 \times 0.08}{0.06 \times 0.08 + 0.93 \times 0.92}[/tex] = 0.0056

d) Probability that the person test negative for HIV is not infected with HIV (P(not HIV|-ve))  = 1 - 0.0056 = 0.9944

One angle in a triangle has a measure that is three times as large as the smallest angle. The measure of the third angle is 25 degrees more than that of the smallest angle. Find the measure of the LARGEST angle.

Answers

The measure of the largest angle of the triangle is 93°, while the measure of the smallest and the third angle is 31° and 56° respectively. Considering that the measure of the third angle is 25 degrees more than that of the smallest angle.

Sum of interior angles of a triangle

In any given triangle, the sum of its interior angles is equal to 180°.

Let the smallest angle be represented by x, so that the other angles are 3x and x + 25.

thus

x + 3x + x + 25 = 180° {collect like terms}

5x + 25° = 180°

5x + 25° - 25° = 180° - 25° {subtract 25° from both sides of the equation}

5x = 155°

x = 155°/5 {divide through by the coefficient of x}

x = 31°

thus the other angles are derived by substituting the value 31° for x as follows;

3(31) = 93°

31° + 25° = 56°

Therefore, the largest angle of the triangle 93°, the smallest angle is 31° and the measure of the third angle is 56°.

what is the expected sum of the numbers that appear when three fair dice are rolled? (enter the value in decimal format.)

Answers

The expected sum of the numbers that appear when three fair dice are rolled, is 10.5.

In the given question we have to find the expected sum of the numbers that appear when three fair dice are rolled.

As we know that a dice have six faces. Each faces are mark from the number 1 to 6.

That means if we rolled a dice then there is possibility of coming six numbers. That numbers are 1, 2, 3, 4, 5, 6.

Now the sum of these numbers is

1+2+3+4+5+6 = 21

Total numbers are 6.

So the expected sum of the numbers that appears when one fair dice is rolled

how many integers can be represented as a difference of two distinct members of the set $\{1, 2, 3\}$?

Answers

We can represent 4 integers as a difference of two distinct members i.e.    {1, -1, 2, -2}.

What are Integers ?

The collection of positive and negative integers is known as an integer. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions.

Here, we have 3 distinct positive integers which are {1, 2, 3}.

We can list down the integers as a difference of the two distinct members as follows :

1 - 2 = -1

2 - 1 = 1

2 - 3 = -1

3 - 2 = 1

1 - 3 = -2

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant b.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear equation or function is given as ;

y = mx + b

Now,

At x = 0 ⇒ y = b so it will be a y-intercept.

Put m = 7 , x = 1 and y = 8

8 = 7(1) + b

b = 1

if you have 200 meters of fencing and want to enclose a rectangular area up against a long, straight wall, what is the largest area you can enclose?

Answers

1600 square meters is the greatest area that may be enclosed.

 Rectangle.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

If fencing is required for 200 meters, then the enclosed area's perimeter is 200 meters.

Perimeter of rectangle = 2(L + B)

2(L+B) = 200

Divide both sides by 2

L+B = 100

L = 100 - B

Here,

Area(A) = L X B

Substitute L = 100 - B into the equation above

A = (100 - B) x B

A = 100B - B²

At maximum area dA/dB = 0

dA/dB = 100 - 2B

100 - 2B = 0

2B = 100

B = 100/2

B = 50m

So L = 100 - 50

L = 50m

Maximum area to be enclosed = 50 x 50

Maximum area to be enclosed = 2500 square meters

Answers

37 is the minimum possible value for N.

Given,

Sharks' current winning percentage is 1/3*100, or 33.33%.

Since Shark's winning rate must be at least 95%, we must determine the lowest number of N that can be used. Sharks must thus win every one of the N games in order to reduce N.

Total matches therefore equal N+3.

When sharks have a 95% winning percentage, tigers will have a 5% winning percentage. And they'll only triumph in two games overall.

Therefore,

2 matchups represent 5% of all matches.

As a result, there were 40 total matches (2/5*100).

So,

N+3 = 40 => N= 37

As an alternative, you can determine the solution by solving the following equation.

The y value of the y-intercept is 146 feet while the slope is -4 feet per second

How to find the y value of the y-intercept and the meaning?

it was given that Kaliel starts at a height of 142 feet. That means at time 0 second (the start), he is at height 142 feet. So this is y-intercept i.e. time = 0 (x-axis), height = 146  (y-axis)

Thus, the y value of the y-intercept is 146 feet

In this case, the slope is defined as the rate of change in height with time i.e the rate at which he descends

Slope = Change in height / Change in time

From the table, the time given is 8 and 13 when the height is 110 and 94. Slope will be:

Slope = (94-110) /(12-8)

Slope = -16/4

Slope = -4

It would have to be numbers that end in 0.  Numbers that are divisible by 5 end in 0 or 5, but numbers divisible by 2 do not end in 5, so only the numbers that end in 0 are divisible by 2 and 5.

how to find the points?

Answers

As described in the analytic geometry, the points are(1.1, -5 )

What is analytic geometry?

The area of algebra known as analytical geometry uses an ordered pair of numbers known as coordinates to determine the position of a point on a plane. It is utilized to model many plane objects, including points, lines, and others. The terms Coordinate geometry and Cartesian geometry are both used to refer to analytical geometry.

We have to locate the point where the line is through the x line and y line coordinates

Therefore the point is  (1.1, -5 )

What is an exponential function?

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Given here: A hive of bees contains 27 bees when it is first discovered. After 4 days, there are 45 bees. The population of bees also increase exponentially.

let the function that gives the population of bees after given days

f(x)=aˣ27

a⁴×27=45

       a= [tex]\sqrt[4]{45/27}[/tex]

        a=1.1362

Thus for x= 40 we have f(40)=1.1362⁴⁰×27

                                               = 4465.69

                                               =4467 (approx)

Hence, After 40 days 4467 bees will be the population after 40 days
