9,000,000,000 is the best estimate of the number of bottles sold this year and last year
What is Number system?A number system is defined as a system of writing to express numbers.
Given,
Current year consumers purchased 7,234,267,990 bottles of water
Last year consumers purchased 2,000,900,999 bottles of water.
We need to find the best estimate of the number of bottles sold current year and last year.
The best estimate means rounding up to the nearest whole number.
The estimate of the bottles sold this year and last year from the above value is:
= 7,000,000,000 + 2,000,000,000
= 9,000,000,000
Hence, 9,000,000,000 is the best estimate of the number of bottles sold this year and last year

If the upect wa elected from a group of upect of which only 5% have ever committed a crime, and the erum indicate that he i guilty, what i the probability that he i innocent
Therefore in this question the probability that he is innocent is 0.1743
What is probability?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
Therefore in this question the probability that he is innocent is 0.1743

Triangle JKL is similar to triangle STU. What is the length of side LK?
Using mathematical operations, we can conclude that the length of LK is 1.25 units in triangle JKL.
What are mathematical operations?
A mathematical "operation" is indeed the method by which a value utilizes operands and a math operator.
The supplied operands or numbers must conform to a set of predefined rules that are connected to the symbol of the math operator.
Parentheses, Exponents, Arithmetic, Division, and Addition Simple arithmetic is also known as PEMDAS (from left to right).
So, we know that the given triangles are similar:
Then, the length of line LK will be:
JK/ST = LK/UT
Solve this as follows:
JK/ST = LK/UT
2.5/10 = LK/5
10LK = 2.5(5)
10LK = 12.5
LK = 12.5/10
LK = 1.25
Therefore, using mathematical operations, we can conclude that the length of LK is 1.25 units in triangle JKL.

There were 3 students who failed the test and also did not complete the assignment. What is the probability that a student chosen randomly from the class completed the homework?
The chance that a student is selected at random from the class who passed the exam and finished the assignment is 0.2105
Describe probability.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

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

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.
What is 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
After simplifying, we get 2002.

A rectangle is constructed on a semicircle so that the length equals the diameter. The rectangle is 3 times as long as it is wide. The total area of the figure is 750 inches squared. Find the approximate dimensions of the rectangle.
A rectangle is constructed on a semicircle so that the length equals the diameter. The width of the rectangle is approximately 10.65 inches.
What are the approximate dimensions of the rectangle.?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.
