The chance that a student is selected at random from the class who passed the exam and finished the assignment is 0.2105

Probability refers to potential. The occurrence of a random event is the subject. Probability values are limited to the range of 0 to 1. Its fundamental notion is that something is probable to occur. It is the proportion of favorable events to all other events.

A exam and an assignment were due on the same day in a math class with 19 pupils.

There were 14 students that finished the assignment, and 11 of them completed the test.

3 pupils both failed the exam and didn't finish the assignment.

Then the probability that a student is chosen randomly from the class passed the test and completed the homework will be

The number of the student who has done at least one assignment or passed the test is 19 - 3 = 16

n(A) = passes student

n(B) = given assignment

Then we have

n(A ∩B) = n(A) + n(B) - n (A ∪B )

n(A ∩B) = 11 + 14 - 16

n(A ∩B) = 9

Then the probability will be

P = 9C2 /19C2

P = 36/171

P = 0.2105

The probability that a student chosen randomly from the class completed the homework is 0.2105

Step-by-step explanation:

A rectangle is constructed on a semicircle so that the length equals the diameter. The width of the rectangle is approximately 10.65 inches.

Generally, Let the width of the rectangle be x. Then the length of the rectangle is 3x.

The diameter of the semicircle is also the length of the rectangle, so it is 3x.

The area of the rectangle is x*(3x) = 3x^2. The area of the semicircle is (1/2)πr^2, where r is the radius of the semicircle. Since the diameter of the semicircle is 3x, the radius is (3x)/2. The area of the semicircle is (1/2)π((3x)/2)^2 = (9/8)πx^2.

The total area of the figure is the sum of the area of the rectangle and the area of the semicircle. We can set up the equation:

3x^2 + (9/8)πx^2 = 750

(21/8)πx^2 = 750

x^2 = 750/(21/8)*π

x = √(750/(21/8)*π)

To find the approximate dimensions of the rectangle, we can use the fact that pi is approximately 3.14. This gives us:

x = √(750/(21/8)*3.14)

= √(750/6.71)

= √(112.64)

= approximately 10.65 inches.

The width of the rectangle is approximately 10.65 inches. The length of the rectangle is 3 times the width, so it is approximately 31.95 inches.

Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.

Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

The probability that exactly 5 small businesses will fail during a given month 0.0037268.

The Poisson distribution would be used to calculate the likelihood that different counts of the same event will occur within a constrained time period. It is viewed as a discrete distribution since it evaluates counts. The distribution displays identical mean and dispersion values.

The pmf of the Poisson distribution is

[tex]p(x)=\frac{e^{\lambda} \lambda^{x}}{x!}[/tex]

The mean total number of small business failures λ=14

Let x represent the number of failed small businesses in a given month.

X~P(14)

X follows the Poisson distribution since the likelihood of failure stays constant for two months and the mean number of failures per month is 14.

The likelihood that precisely four small firms would fail in a given month must be calculated.

P(X=5)

[tex]P(X=5)= \frac{e^{14} \ 14^{5}}{5!}[/tex]

P(X=5)= 0.44721/5!

P(X=5)=0.0037268.

In a month there is 0.0037 that is 3.7% probability that a small business fail.

Therefore in this question the probability that he is innocent is 0.1743

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Here,

In this case, let G represent the state of guilt and H represent the state of innocence.

and Let K stand for the situation where the truth serum shows that someone is guilty.

We are aware that 90% of the guilty suspects receive just verdicts, i.e. P(K|G)=0.9.

Additionally, we know that innocent suspects are mistakenly identified 1% of the time, or P(K|H)=0.01.

When a suspect is chosen from a group of suspects, of whom 5% committed a crime, and the serum suggests that the suspect is guilty, we must determine the likelihood that the suspect is innocent.

We must therefore determine the probability P(H|K).

A group of people was chosen for the suspect, of which 5% were criminals.

so the probability that selected person is guilty is

P(G) = 0.05

Therefore, the probability that selected person is not guilty is

P(H) = 1 – P(G) = 1 – 0.05 = 0.95

Then,

Using Bayes' Theorem, we get

P(H|K) =[tex]\frac{P(H)P(K|H)}{P(H)P(K|H) + P(G)P(K|G)}[/tex]

=     [tex]\frac{0.95*0.01}{0.95*0.01 + 0.05*0.9}[/tex]  =0.1743

a local winery bottles 14 different white wines. to help customers with their purchasing choice, the winery offers customers 5 white wine tasting samples free of charge 2002 many ways does a customer have to choose 5 different white wines to taste, using the concept of combination formula.

The number of possible ways to choose items from a collection when the order of choice is irrelevant is determined using the combination formula. Combination, to put it simply, is the process of choosing items or things from a bigger group where order is irrelevant.

The combination formula is: n! / (n-r)! r! , where n is the total number of items (14 in this case) and r is the number of items being selected at once (5 in this case),

Plugging our numbers into the formula we get:

= 14! / (14-5)! 5!

= 2002

Two figures are similar when they have some common properties. The value of PQ as required is 28 units.

Similar triangles are two or more which have a series of common properties. This may be in relations to the length of their sides or measure of their angles.

In the given triangle PQR,

ΔPQS ll ΔSTR

Given that PS = RS, and QT = RT.

Then we can say that;

[tex]\frac{RS}{ST}[/tex] = [tex]\frac{PQ}{PQ}[/tex]

But, PR = 2RS;

[tex]\frac{RS}{ST}[/tex] = [tex]\frac{2RS}{PQ}[/tex]

[tex]\frac{1}{ST}[/tex] = [tex]\frac{2}{PQ}[/tex]

2ST = PQ

2(-22 + 9x) = 9x - 8

-44 + 18x = 9x - 8

18x - 9x = -8 + 44

9x = 36

x = 4

So that,

PQ = 9x - 8

PQ = 36 - 8
