The correct answer as per the video that demonstrates the Monty Hall Problem is option C. 20. That is how many times the men perform each strategy A and B.
Goats can be found behind two curtains and one behind each door.
Anytime a contestant selects a curtain, one of the certain to curtains informs the contestant that a goat was hiding behind all of this.
The contestant must choose one of two curtains, one of which has a car in it and the other of which has a goat on it. Therefore, there is an equal chance of. choosing either a goat or a car.
Similar to that, provided.
Probability A for strategies and tactics is 10%, or 2 out of every 20 trials.
80% of Strategy B's chance is equal to 16 accomplishments spread across 20 directions.
Thus,
16 success = 2 success + 2 success + 2 success + 2 success + 2 success + 2 success + 2 success + 2 success
Taking the common factor,
16 success = 8 (2 success)
Taking percentage on both sides,
80% = 8×10%
80% = 80%
Hence, the result value is as expected.

what is binary to text conversion?
Binary to text conversion is the process of translating binary code, which is a series of 0s and 1s, into human-readable text. This process is necessary because computers use binary code to represent data, while humans use text.
To convert binary code to text, the binary code is first grouped into 8-bit groups called bytes. Each byte can represent a single character in the ASCII (American Standard Code for Information Interchange) character set, which includes letters, numbers, punctuation, and other symbols.
The binary code in each byte is then converted into its decimal equivalent, and the decimal value is looked up in the ASCII table to determine the corresponding character. This process is repeated for each byte in the binary code to produce the final text output.
Overall, binary to text conversion is an important process that allows humans to read and interpret data that is represented in binary code by computers.

The functions below represent the cost some homeowners pay for water and sewer usage. This is based on the number of 100-gallon units
of water used, defined by x.
Water usage: W(x) = 0.129x
Sewer usage: S(x) = 0.158x + 16.22
Based on this information, approximately what is the total amount a homeowner will pay if the water and sewer usage for one month is 3800
gallons?
A. $10.91
B. $21.12
C. $27.13
D. $43.35
Since the given functions represent the cost for water and sewer separately, the total cost will be the sum of both.
For water usage, W(x) = 0.129x, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:
W(x) = 0.129 * (3800/100) = $4.91 (rounded to the nearest cent)
For sewer usage, S(x) = 0.158x + 16.22, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:
S(x) = 0.158 * (3800/100) + 16.22 = $21.12 (rounded to the nearest cent)
Therefore, the total amount a homeowner will pay for 3800 gallons of water and sewer usage for one month is:
Total cost = W(x) + S(x) = $4.91 + $21.12 = $26.03 (rounded to the nearest cent)
So, the closest answer choice is C. $27.13.

I ride four times faster than I jog. If a trip took me 45 minutes and I spent 15 of these minutes jogging 3km, how far did I ride ?
Answer:
24km
Step-by-step explanation:
15 min (jogging)
30 min (cycling)
3km/15 min (jogging)
1km/5min (jogging)
4km/5min (cycling)
30÷5= 6
4×6= 24km
Distance covered during riding is 24 km.
What is meant by speed ?Speed of an object is defined as the rate of change of the distance travelled.
Here,
Speed is the distance travelled in a given time.
Total time given, t = 45 minutes
Time taken for jogging, t₁ = 15 minutes
So, time taken for riding, t₂ = t - t₁
t₂ = 45 - 15
t₂ = 30 minutes
Distance covered during jogging, d₁ = 3 km
Therefore speed of jogging, v₁ = d₁/t₁ = 3/15
v₁ = 0.2 km/min
So, speed of riding, v₂ = 4v₁ = 4 x 0.2
v₂ = 0.8 km/min
Therefore distance covered during riding, d₂ = v₂ x t₂
d₂ = 0.8 x 30
d₂ = 24 km

When Jayden left his house in the morning, his cell phone battery was partially charged. Let B represent the charge remaining in Jayden's battery, as a percentage, t hours since Jayden left his house. The table below has select values showing the linear relationship between t and B. Determine how many hours after leaving his house it would take until the phone's battery level got down to 31.5%. t B 1.5 38.25 6 18. 8. 9
It would take 11.25 hours after leaving his house until the phone's battery level got down to 31.5%.
According to given conditions :
To determine how many hours after leaving his house it would take until the phone's battery level got down to 31.5%, we need to use the information provided in the table to find the equation of the line that represents the relationship between B and t. We can then use this equation to solve for the value of t when B is 31.5%.
To find the equation of the line, we can use the two points (1.5, 38.25) and (9, 9). The slope of the line is:
slope = (B2 - B1) / (t2 - t1) = (9 - 38.25) / (9 - 1.5) = -29.25 / 7.5 = -3.9
The equation of the line in point-slope form is:
B - 38.25 = -3.9(t - 1.5)
Simplifying, we get:
B = -3.9t + 44.1
Now we can solve for the value of t when B is 31.5%. Setting B to 31.5% (or 0.315) and solving for t, we get:
0.315 = -3.9t + 44.1
-3.9t = -43.785
t = 11.25
Therefore, it would take 11.25 hours after leaving his house until the phone's battery level got down to 31.5%.
What is percentage ?
A percentage is a number or ratio expressed as a fraction of 100. The symbol used to represent percentages is "%". Percentages are used to compare values and express proportions. For example, if a group of 100 people includes 60 men and 40 women, we can say that the percentage of men in the group is 60%, and the percentage of women is 40%.
To calculate a percentage, we divide the value we want to express as a percentage by the total value, and then multiply by 100. For example, if we want to express 25 as a percentage of 100, we divide 25 by 100 to get 0.25, and then multiply by 100 to get 25%. Similarly, if we want to find what percentage of 200 is 50, we divide 50 by 200 to get 0.25, and then multiply by 100 to get 25%.
Percentages are used in many different fields, including finance, science, and statistics, as well as everyday life. For example, we might use percentages to calculate the amount of tax on a purchase, to compare the results of scientific experiments, or to track the progress of a fundraising campaign.

The relative retention of compound B with respect to compound A is 0.053.
The relative retention is defined as the ratio of the difference in retention times of two compounds (α) to the retention time of the first eluting compound (tr1):
α = (tr2 - tr1) / tr1
where tr2 is the retention time of the second compound.
In this case, compound A eluted at 12.63 min and compound B eluted at 13.30 min. The compound that is not retained by the stationary phase eluted at 1.145 min.
Therefore, tr1 = 1.145 min, tr2 = 13.30 min, and:

and 2x+y=8 --->2 will be the equations formed.
Now subtracting 2 from 1
we get 2x-2x+3y-y=20-8
2y=12
y=6
then 2x+6=8
x=1
Hence,
the cost of a t-shirt and a notebook will be $1 and $6 respectively.

what is trig identities calculator?
A trigonometric identities calculator is an online tool that helps you simplify or prove trigonometric identities using various trigonometric formulas and rules.
Describe Equation?In mathematics, an equation is a statement that asserts the equality of two expressions. An equation contains one or more variables, which are unknown values that can vary or change. The variables are usually represented by letters such as x, y, or z. The expressions on either side of the equals sign can be constants, variables, or functions of variables.
The simplest form of an equation is a linear equation, which can be represented as ax + b = c, where a, b, and c are constants and x is a variable. To solve a linear equation, we need to find the value of the variable that makes the equation true. This is done by performing arithmetic operations on both sides of the equals sign to isolate the variable.
Equations can also be more complex, involving multiple variables, powers, and functions. In such cases, algebraic techniques such as factoring, substitution, and solving systems of equations may be required to find the solution.
Equations are used to describe relationships between variables in many fields of study, including physics, chemistry, economics, and engineering. They are also used in everyday life, such as in calculating the cost of a purchase after applying a discount, or determining the amount of time it takes to travel a certain distance
