A common denominator is a shared multiple of the denominators of the fractions involved when adding or subtracting fractions. It enables fraction comparison and addition/subtraction.
Simplification is the process of reducing a fraction to its simplest form by dividing the numerator and denominator by their greatest common divisor. This is done to represent fractions in the simplest terms viable.
Conversion: The process of transferring a fraction from one form to another while retaining its equal value is known as conversion. Finding a common denominator or expressing a fraction in terms of a specified unit or fraction may be required.
Fraction Addition/Subtraction: When adding or subtracting fractions, a common denominator is required. This entails determining a common multiple of
To rewrite the expression 3 + 1/5 + 2/3 using fifteenths as the common denominator, we need to find a common denominator for 5 and 3, which is 15 (since 5 and 3 are both factors of 15).
First, let's convert the fractions 1/5 and 2/3 to fifteenths:
\((\frac{1}{5})(\frac{3}{3}) = \frac{3}{15}\)
\((\frac{2}{3})(\frac{5}{5}) = \frac{10}{15}\)
Now we can rewrite the expression using the common denominator:
\(3 + \frac{3}{15}+\frac{10}{15}\)

The data collected in the study is observational data.
Step-by-step explanation:
In an experimental study, the data collected is divided into two groups. One group is the control group. The other group is the treatment group (also known as the experimental group). Data is gathered about the groups in order to compare their different outcomes and to draw conclusions if there is any causality based on the two variables. With observational data, the researcher is interested in observing the variables to determine if there is any correlation.

Que es una fraccionLas fracciones o decimales se utilizan para representar partes de un todo. Una fracción consta de dos números:
Numerador (encima de la línea) y denominador (debajo de la línea).
El denominador indica en cuántas partes iguales se divide algo. Un contador indica cuántas de estas mismas partes se consideran.
Entonces, si la fracción es 3/5 del pastel, el denominador 5 indica que el pastel está dividido en 5 partes iguales, 3 de las cuales (el numerador) son 3/5 de la fracción. Puede ser útil pensar en la línea divisoria (en el medio de la fracción) como "apagada". También significa 3 de cada 5 del mismo tamaño de todo el pastel.

2. What would be the revised net operating income per month if the sales volume decreases by 40 units?
3. What would be the revised net operating income per month if the sales volume is 7,700 units?

2. What is the estimated change in the company’s net operating income if it can increase sales volume by 500 units and total sales by $2,000? (Do not round intermediate calculations.)
Answers
1. Revised Net Operating Income = $66,760
2. Revised Net Operating Income =$64,640
3. Revised Net Operating Income =$52,
1. If the sales volume increases by 40 units:
So, New Sales = 8,700 units + 40 units = 8,740 units
and, New Contribution Margin =
= $14.00 x 8,740 units
= 122, 360
New Fixed Expenses remain the same at $55,600
Then, Revised Net Operating Income
= New Contribution Margin - New Fixed Expenses
= 122360 - 55600
= 66,760.
2. If the sales volume decreases by 40 units:
New Sales = 8,700 units - 40 units = 8,660 units
New Contribution Margin
= 14 x 8660
= 121,240
New Fixed Expenses remain the same at $55,600
Then, Revised Net Operating Income
= New Contribution Margin - New Fixed Expenses
= 65,640
3. If the sales volume is 7,700 units:
New Sales = 7,700 units
New Contribution Margin
= 14 x 7700

A national publication showed the following distribution of favorite class subjects for high school students.
Math: 5% English: 14% Social Studies 28%: PE: 26% Music: 20% Other: 7&
Pasquale, a student from a high school of 1,200 students, wants to see whether the distribution at his school matches that of the publication. He stands at the school entrance in the morning and asks the first 40 students he sees what their favorite class is. Pasquale records the following table of observed values.

It was never specified if the sample was random, but the method of sampling was not random. So I must be true, eliminating B and C. Additionally, not all the expected counts are greater than 5 as 40(0.05)<5, 40(0.14)>5, 40(0.28)>5, 40(0.20)>5, 40(0.26)>5, 40(0.20)>5, and 40(0.07)<5. Therefore, D is the only correct answer.

event a occurs with probability 0.. teh conditional probability that event b occurs, given that a occurs is 0.5. the probability that both a and b occurs is
Answers
The probability of event a occurring is 0 and the conditional probability of event b occurring given that event a has occurred is 0.5.
The probability that both event A and event B occur is calculated using the formula P(A and B) = P(A) x P(B|A).
In this case, P(A) = 0 and P(B|A) = 0.5. When we plug these values into the equation, P(A and B) = 0 x 0.5 = 0. Therefore, the probability of both event A and event B occurring is 0. The probability that both events a and b occur is determined by multiplying the probability of event a occurring with the conditional probability of event b occurring given that event a has already occurred. This can be expressed mathematically as P(A∩B)=P(A)*P(B|A). In this case, the probability of both events a and b occurring is 0.5*0.5=0.25, since the probability of event a occurring is 0 and the conditional probability of event b occurring given that event a has occurred is 0.5.
This makes sense, since event A has a probability of 0 and cannot occur in the first place, so the probability of both events occurring together is 0.
