3 days is 72 hours in those 72 hours i slept 12. 5% how many hours did i sleep in those three days?
You slept for 9 hours in those three days, calculated by multiplying 12.5% of the total hours (72) by 72, which equals 9.
To calculate the number of hours slept in three days, we first need to determine how many hours there are in three days.
As given, 1 day has 24 hours. So, three days will have 3 x 24 = 72 hours.
Now, we are told that you slept for 12.5% of those 72 hours. To calculate this, we multiply the percentage by the total number of hours:
12.5% x 72 hours = (12.5/100) x 72 = 0.125 x 72 = 9 hours
Therefore, you slept for 9 hours in those three days.
Percentage is a way to express a proportion or ratio as a fraction of 100. The sign "%" is widely used to represent it. For example, if you had 20 apples and you ate 5 of them, you would have consumed 25% of the apples (5 out of 20).

Angie is x years old.
Mandy is 22 years older than Angie.
In 2 years’ time, Mandy will be twice Angie’s age.
Calculate Angie and Mandy’s current age.
The Angie and Mandy’s current age are 22 and 44 years respectively.
Explain about the term linear equations?There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as this same denominator of either a fraction in a linear equation.The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.Angie is x years old.
Mandy = 22 + x
After 2 years:
22 + x = 2x
Solving linear equation:
22 = 2x - x
22 = x (Angie’s current age)
Mandy’s current age.
x + 22 = 22 + 22
x = 44
Thus, the Angie and Mandy’s current age are 22 and 44 years respectively.

the different between two possitive nymbers is 48. the lesser number is 1/3 of the greater number. what are the two positive numbers
Let's call the greater number "x" and the lesser number "y". According to the problem, we know that:
x - y = 48 (since the difference between the two numbers is 48)
y = (1/3)x (since the lesser number is one third of the greater number)
Now we can substitute the second equation into the first equation:
x - (1/3)x = 48
Simplifying this equation, we get:
(2/3)x = 48
Multiplying both sides by 3/2, we get:
x = 72
Now that we know x, we can use the second equation to find y:
y = (1/3)x = (1/3)(72) = 24
So the two positive numbers are 72 and 24.

is the point below which a specified percentage of the observations fall.
In mathematics, the point below which a specified percentage of the observations fall is commonly referred to as the percentile.
A percentile is a measure that indicates the relative position of a particular value within a dataset.
For example, if a value is at the 80th percentile, it means that 80% of the observations in the dataset are below that value, and only 20% of the observations are above it.
Percentiles are often used to analyze and understand the distribution of data, especially in fields such as statistics, probability, and data analysis. They provide insights into how individual data points compare to the overall dataset and help identify outliers or extreme values.
A percentile is a statistical measure that indicates the relative standing of a particular value within a dataset. It represents the point below which a specified percentage of the observations or data points fall. Percentiles are primarily used to understand the distribution of data and analyze how individual values compare to the overall dataset.
To calculate a percentile, the dataset is arranged in ascending order, from the smallest value to the largest value. The position of a specific percentile is then determined based on the percentage of data points below it. For example, the 75th percentile represents the value below which 75% of the data points fall.
Percentiles are commonly used in various fields, including statistics, probability, and data analysis. They provide valuable insights into the spread, variability, and distribution of data. Here are a few key points to consider:
1. Median: The median is the 50th percentile, representing the value that divides the dataset into two equal halves. It is a measure of central tendency and provides information about the middle point of the distribution.
2. Quartiles: Quartiles divide the dataset into four equal parts. The first quartile, or the 25th percentile (Q1), represents the value below which 25% of the data points fall. The third quartile, or the 75th percentile (Q3), represents the value below which 75% of the data points fall. The difference between Q3 and Q1 is known as the interquartile range (IQR) and provides insights into the spread of the middle 50% of the data.
3. Percentile Ranks: Percentile ranks indicate the percentage of data points that are below a specific value. For example, if a student scores in the 80th percentile on a standardized test, it means they performed better than 80% of the test-takers.
4. Outliers: Percentiles can be useful in identifying outliers, which are data points that significantly deviate from the rest of the dataset. Extremely high or low percentiles may indicate unusual or extreme values that warrant further investigation.
5. Normal Distribution: In a normal distribution, the 50th percentile (median) coincides with the mean and mode, and specific percentiles have known standard deviations from the mean (e.g., the 68-95-99.7 rule).
Percentiles are versatile tools for summarizing and analyzing data, providing valuable insights into the distribution and relative positions of individual values. They enable comparisons and help make informed decisions based on the characteristics of a dataset.

Urn A has four red and four black balls and Urn B has two red and six black.
You pick an urn at random (50% chance of picking A and the same for B) and
draw a red ball from it. What is the probability that it was Urn A? Provide a
calculation to support your answer.
If a red ball is drawn at random from one of the urns, there is a higher probability (2/3) or 0.667 that it came from Urn A rather than Urn B. This suggests that Urn A is more likely to be the source of the red ball.
To calculate the probability that Urn A was chosen given that a red ball was drawn, we can use Bayes' theorem.
Let's denote the events:
A = Urn A was chosen
B = Urn B was chosen
R = A red ball was drawn
We want to find P(A|R), the probability that Urn A was chosen given that a red ball was drawn.
According to Bayes' theorem:
P(A|R) = (P(R|A) * P(A)) / P(R)
P(R|A) is the probability of drawing a red ball given that Urn A was chosen. Since Urn A has four red balls and four black balls, the probability of drawing a red ball from Urn A is 4/8 = 1/2.
P(A) is the prior probability of choosing Urn A, which is 0.5 since there is an equal chance of selecting either Urn A or B.
P(R) is the overall probability of drawing a red ball, which can be calculated by considering all possible scenarios:
P(R) = P(R|A) * P(A) + P(R|B) * P(B)
P(R|B) is the probability of drawing a red ball given that Urn B was chosen. Since Urn B has two red balls and six black balls, the probability of drawing a red ball from Urn B is 2/8 = 1/4.
P(B) is the prior probability of choosing Urn B, which is also 0.5.
Substituting the values into the equation:
P(R) = (1/2) * (1/2) + (1/4) * (1/2) = 3/8
Now we can calculate P(A|R) using Bayes' theorem:
P(A|R) = (P(R|A) * P(A)) / P(R) = (1/2 * 1/2) / (3/8) = 4/6 = 2/3
Therefore, the probability that Urn A was chosen given that a red ball was drawn is 2/3 or approximately 0.667.
In conclusion, if a red ball is drawn at random from one of the urns, there is a higher probability (2/3) that it came from Urn A rather than Urn B. This suggests that Urn A is more likely to be the source of the red ball.

how do we decide whether to use a t test or an analysis of variance (anova) to analyze the data from an experiment?
The best way to analyze their data for significance is to Conduct a two-way variable analysis.
As we can see, there is a 2x3 factorial design. Thus, we know that there will be a two level or two way analysis of variables, which is referred to as two way variables analysis. Factorial design is a research method that allows for the inquiry of a main and interaction effects of two or more independent variables on one or more outcome variables (s).
It has been argued that factorial designs represent the true beginning of modern behavioral research and have resulted in a significant paradigm shift in how social scientists conceptualize their research questions and produce objective results (Kerlinger & Lee, 2000).
Factorial design is an experimental methodology that goes beyond standard single-variable experimentation. Previously, social scientists were fixated on single independent variable experiments, foreshadowing the significance of extraneous variables that can attenuate or diminish research findings.

f(x) = x³ − 2 and g(x) = −2x
Find the formula for (f+g)(x) and simplify your answer. Then find the domain for (f+g)(x). Round your answer to two decimal places, if necessary.
The formula for (f+g)(x) is (f+g)(x) = x³ - 2x - 2.
The domain for (f+g)(x) is all real numbers, or (-∞, ∞).
To find the formula for (f+g)(x), we need to add the functions f(x) and g(x).
f(x) = x³ - 2
g(x) = -2x
(f+g)(x) = f(x) + g(x) = (x³ - 2) + (-2x)
Combining like terms, we have:
(f+g)(x) = x³ - 2 - 2x
Simplifying further, we can rearrange the terms:
(f+g)(x) = x³ - 2x - 2
To find the domain for (f+g)(x),
we need to consider any restrictions on x that would make the function undefined.
In this case, since (f+g)(x) is a polynomial,
there are no specific restrictions on the domain.
Polynomial functions are defined for all real values of x.

5. The values of f(x) and g(x) are the same at x = 3
Answer:
4. 5. 3. are correct im pretty sure
Step-by-step explanation:
Statements 1, 2, and 3 about f(x) and g(x) are "true".
What are the functions?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
Consider the function f(x) = 3x - 2 and the function g(x), which is represented by the table below.
x : 1 3 5 7 9
g(x): 3 7 11 15 19
Here the slope of the function g(x) is 2.
This means statements 1 and 2 are false because slopes are different.
To compare the position of the lines at the x-axis, you can evaluate the function at x=0. f(0) = 3×0 - 2 = -2 and g(0) = -1.
Since g(0) is less than f(0), the line represented by g(x) crosses the x-axis to the right of the line represented by f(x). So, statement 3 is true.
The y-intercept of f(x) is -2, while the y-intercept of g(x) is 1. So, statement 4 is true.
To compare the values of f(x) and g(x) at x=3, you can evaluate the functions at x=3. f(3) = 3×3 - 2 = 7 and g(3) = 7. So, the values of f(x) and g(x) are the same at x=3. So, statement 5 is true.
Therefore, the true statements are 2, 3, and 4.

A group of 3 children can make 40 cups of lemonade to sell at their lemonade stand in an hour. When another child is added, they are able to make 34 cups of lemonade in an hour. Calculate the marginal product of adding the 4th child
In the addition of another child in the process of making lemonade, the marginal productivity of the whole group was decreased that they started to make -6 cups than previous.
To compute the marginal product of adding the fourth kid, we must first determine the additional output produced by adding one more unit of input (the fourth child).
With three youngsters, the group's initial production is 40 glasses of lemonade per hour. This means that their average productivity per child is:
Average productivity per child = Total productivity / Number of children = 40 cups / 3 children
Average productivity per child = 13.33 cups/child
With the addition of a fourth youngster, the group's overall production rises to 34 cups per hour. This means that their average productivity per child with four children is:
Average productivity per child = Total productivity / Number of children = 34 cups / 4 children
Average productivity per child = 8.5 cups/child
To calculate the marginal product of adding a fourth kid, subtract the total production of the group with four children from the total productivity of the group with three children:
Marginal product = Total productivity with 4 children - Total productivity with 3 children
= 34 cups/hour - 40 cups/hour
Marginal product = -6 cups/hour
The negative sign indicates that adding the fourth child has resulted in a decrease in productivity. This could be due to factors such as coordination and communication challenges that arise when working in larger groups.
