Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned does not represent a function.
In a function, each input (or x-value) should have a unique output (or y-value). However, in this situation, the total amount of money charged monthly on credit cards depends on the number of credit cards owned. It is possible to have different credit card numbers but still have the same total amount of money charged monthly.
For example, two people could own different numbers of credit cards but have the same monthly charges.
As a result, the definition of a function can be violated by having many outputs (monthly charges) for a single input (number of credit cards).
Because of this, case 3 does not represent a function.

a man buys eggs at RS 9.60 per dozen and sell 20 eggs for RS 18 what is his gain or loss percen?
Answers
Answer:
Percentage Gain = 12.5%
Step-by-step explanation:
Given
\(Cost\ Prize = 9.60\) per dozen
\(Selling\ Price = 18\) per 20
Required
Determine the percentage gain or loss
First, we have to calculate the unit cost price and the unit selling price.
If a dozen costs 9.60
Then 1 costs
\(Cost = 9.60/12\)
\(Cost = 0.80\)
If he sells 20 for 18
Then he sells 1 for:
\(Sell = 18/20\)
\(Sell = 0.9\)
The percentage change is then calculated as:
\(\%Change = \frac{Sell - Cost}{Cost} * 100\%\)
\(\%Change = \frac{0.9 - 0.8}{0.8} * 100\%\)
\(\%Change = \frac{0.1}{0.8} * 100\%\)
\(\%Change = \frac{0.1 * 100\%}{0.8}\)
\(\%Change = \frac{10\%}{0.8}\)
\(\%Change = 12.5\%\)
Because the percentage change is positive, then he made a gain.
Hence:
Percentage Gain = 12.5%

This data collection may be characterized as numerical and univariate.
How do you define numerical and univariate?A numerical univariate data is discrete if the totality of all possible values is finite or countably infinite. Usually, counting is done using discrete univariate data (such as the number of books read by a person). A numerical univariate data is continuous if the range of all possible values is a set of integers.
What is Categorical data?Different categories of data that can be categorized are represented by categorical variables. Examples of categorical variables are race, sex, age group, and educational attainment.
Categorical data are data kinds that can be stored and identified depending on the names or labels given to them.
Data that is expressed as numbers rather than in any linguistic or descriptive form is referred to as numerical data. As it validates data before classification, it is also known as qualitative data.

Finde the value of x in the proportion ( 5x+ 1 ):3 =(2x +2): 7(6 x) = (4x) :7
Answers
In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.
In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.
To find the value of x in the given proportions, let's solve them one by one:
(5x + 1) : 3 = (2x + 2) : 7
To solve this proportion, we can cross-multiply:
7(5x + 1) = 3(2x + 2)
35x + 7 = 6x + 6
Subtracting 6x from both sides and subtracting 7 from both sides:
35x - 6x = 6 - 7
29x = -1
Dividing both sides by 29:
x = -1/29
Therefore, the value of x in the first proportion is -1/29.
(6x) : (4x) = 7
To solve this proportion, we can simplify the left side:
6x / 4x = 7
Dividing both sides by 2x:
3/2 = 7
This equation is not true, as 3/2 is not equal to 7.
Therefore, there is no value of x that satisfies the second proportion.
In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

Mr.Blackwell’s class is conducting an experiment to find the probability of pulling certain colors from a bag of 25 marbles. If 6 are purple, 3 are yellow, 7 are green, and the rest are black, what is the probability of drawing a purple and yellow if the marbles are not replaced after they are picked?
Answers
Answer:
Step-by-step explanation:
To find the probability of drawing a purple and yellow marble without replacement, we need to determine the number of favorable outcomes (purple and yellow marbles) and the total number of possible outcomes.
Step 1: Determine the number of purple marbles:
The given information states that there are 6 purple marbles.
Step 2: Determine the number of yellow marbles:
The given information states that there are 3 yellow marbles.
Step 3: Determine the total number of marbles:
The given information states that there are 25 marbles in total.
Step 4: Calculate the probability of drawing a purple and yellow marble:
When drawing without replacement, the probability of two events occurring is the product of their individual probabilities.
The probability of drawing a purple marble is: 6 purple marbles / 25 total marbles = 6/25.
After drawing a purple marble, the total number of marbles remaining is 24 (since one purple marble is already drawn).
The probability of drawing a yellow marble from the remaining marbles is: 3 yellow marbles / 24 remaining marbles = 3/24.
To find the probability of both events occurring (drawing a purple and yellow marble), we multiply their individual probabilities:
Probability of drawing a purple and yellow marble = (6/25) * (3/24) = 18/600 = 3/100.
Therefore, the probability of drawing a purple and yellow marble without replacement is 3/100.

1. What is the company’s contribution margin (CM) ratio?
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

Answers
Using the uniform distribution, it is found that:
a) There is a 0.3333 = 33.33% probability that the friend is between 10 and 20 minutes late.
b) Within 9 minutes.
What is the uniform probability distribution?It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
\(P(X < x) = \frac{x - a}{b - a}\)
The probability of finding a value between c and d is:
\(P(c \leq X \leq d) = \frac{d - c}{b - a}\)
Researching the problem on the internet, it is found that the variable is uniform with a = 0 and b = 30.
Item a:
\(P(10 \leq X \leq 20) = \frac{20 - 10}{30 - 0} = 0.3333\)
There is a 0.3333 = 33.33% probability that the friend is between 10 and 20 minutes late.
Item b:
This is x for which P(X < x) = 0.3, hence:
\(P(X < x) = \frac{x - a}{b - a}\)
\(0.3 = \frac{x}{30}\)

If f(x)=x² – 4x, what is the value of 2f(a-1)?
Answers
The correct value of 2f(a-1) is 2a^2 - 12a + 10.
To find the value of 2f(a-1), we need to substitute (a-1) into the function f(x) and then multiply the result by 2.
Given: f(x) = x^2 - 4x
Substituting (a-1) into the function:
f(a-1) = (a-1)^2 - 4(a-1)
Expanding and simplifying:
f(a-1) = (a^2 - 2a + 1) - (4a - 4)
f(a-1) = a^2 - 2a + 1 - 4a + 4
f(a-1) = a^2 - 6a + 5
Now, we multiply the result by 2:
2f(a-1) = 2(a^2 - 6a + 5)
Expanding:
2f(a-1) = 2a^2 - 12a + 10
Therefore, the value of 2f(a-1) is 2a^2 - 12a + 10.
