Answers
As universal set defined the set containing all objects or elements and of which all other sets are subsets. So, the answer is B.
Answer:
Universal set
Step-by-step explanation:
We need to find U in the upper right corner stands for what
Option 1 : bigger set
We cannot say this a bigger set without comparing it with another sets and since it is also containing another sets So, it is not said to be a bigger set.
Option 1 is wrong .
Option 2 : Universal Set
Definition of Universal Set : The set which contains all elements or all objects and of which all other sets are subsets.
Since we can see that SET M and SET N are contained in SET U
Thus U is a universal set.
Option 2 is correct .
Option 3: infinite set
we can see in the figure that it is finite set .
So, it is not infinite set.
Option 3 is wrong .
Option 4: complement
it is not a complement set (refer given figure )
Option 4 is wrong .

what is the slope of 3x + 4Y = 24
Answers
The slope of the line 3x + 4y = 24 is -3/4.
The slope of a line is determined by the coefficient of x in the equation of a line written in the form y = mx + b, where m represents the slope.
In the equation 3x + 4y = 24, rearranging it to the slope-intercept form y = mx + b gives 4y = -3x + 24, and then y = -3/4x + 6. Thus, the slope is -3/4.
you randomly draw a marble from a bag of marbles that contains 7 blue marbles, 2 green marbles, and 1 red marble. what is the probability not draw a blue marble
Answers
Answer:
0.3
Step-by-step explanation:
It is given that,
Number of blue marbles = 7
Number of green marbles = 2
Number of red marbles = 1
Total number of marbles = 7+2+1=10
We need to find the probability that we do not draw a blue marble.
[tex]P=\dfrac{\text{Number of non-blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P=\dfrac{2+1}{10}[/tex]
[tex]P=\dfrac{3}{10}[/tex]
[tex]P=0.3[/tex]
Therefore, the required probability is 0.3.
what is the difference between all real numbers and no solution how do you know when these situations occur
Answers
example
simplifying results in x=x or 8=8 or 0=0 or something liek that
an example equation would be 2(x+1)=2x+2, simplifies to x=x or 2=2 or 0=0
no solution is when you get a false statement from simplifying
example, 3=4 or -1=0
an example equation could be 2(x+1)=2x+3, it simplifies to 2=3 which is false
The difference between 'all real numbers' and 'no solution' is that the former means any real number satisfies the equation while the latter means no real number satisfies it. These concepts are essential in understanding and solving mathematical problems, which is a skill developed through practice.
Explanation:The difference between 'all real numbers' and 'no solution' in mathematical equations is significant. When an equation has all real numbers as its solution, it means that any real number can be substituted for the variable and the equation would still hold true. This situation typically occurs when both sides of the equation are identical after simplification. For example, if we simplify an equation and end up with a statement like 5 = 5, it implies that all real numbers are solutions since the statement is always true, regardless of the value of the variable.
On the other hand, 'no solution' means that there are no real numbers that satisfy the equation, often arising when a statement is made that is logically false after simplification, such as 0 = 5. Identifying knowns and unknowns and checking if an answer is reasonable are part of the problem-solving process, where we also look for unreasonable results that might suggest 'no solution'.
The occurrence of these situations during problem solving reflects the complexity of real-world problems, where we must determine which information is relevant and sort out the possible from the impossible. This discernment can be developed through consistent practice in evaluating and solving various types of problems. In some cases, particularly in systems of equations, if the number of unknowns is larger than the number of equations, it may indicate that there could be infinite solutions or no unique solution.
Julia wrote 14 letters to friends each month for y months in a row. Write an expression to show how many total letters she wrote.
Answers
The expression representing the total number of letters that Julia wrote after 'y' months is '14y', as she writes 14 letters each month.
Explanation:This is a mathematics problem related to writing algebraic expressions. In this case, Julia has written 14 letters each month for 'y' months. Hence, the expression to determine the total number of letters Julia has written is '14y'. Let's break this down:
Julia writes 14 letters each month. This is a constant, represented by the number 14. The time period over which she continues this action is variable, represented by 'y'. So, for every month 'y', she writes 14 letters. We multiply 14 (letters per month) by 'y' (number of months) to get the total number of letters, hence the expression 14y.Learn more about Algebraic Expression here:

When rewriting y = 2x + 1 in function notation, what do you replace with f(x)?
Answers
Answer:
You replace y with f(x)
Step-by-step explanation:
- Function is a relation between two sets of numbers, with every element
in the first set has only one corresponding element in the second set
- The first set is called the domain of the function (input)
- The second set is called the range of the function (output)
- If the first set is set X and the second set is set of Y, then each value
of x has only one value of y and x is the input and y is the output
- Function notation is the way to write a function f(x) = y, where f(x)
represents the values of y
∵ y = 2x + 1
∵ f(x) = y
- Replace y by f(x)
∴ f(x) = 2x + 1
* You replace y with f(x)
Answer:
That is what I got off of USA Test Prep
Step-by-step explanation:
For function notation you are saying that you have a relation that is a function of another variable. To correctly rewrite using function notation you replace y with f(x).

find the derivative of y=(2x-7)^3
Answers
To find the derivative of y=(2x-7)^3, use the power rule and chain rule. Differentiate each term individually and apply the chain rule. Add all the terms together to get the derivative.
Explanation:To find the derivative of y=(2x-7)^3, we can use the chain rule. First, we can rewrite the equation using the power rule: y = (2x - 7)(2x - 7)(2x - 7). Next, we differentiate each term individually using the power rule and then apply the chain rule. The derivative of the first term will be 2(2x - 7)(2), the derivative of the second term will be 2(2x - 7)(2), and the derivative of the third term will be 2(2x - 7)(2). Finally, we add all these terms together to get the derivative of the original equation.

write 42.5% as a fraction in simplest form
Answers
The fraction of 42.5% in its simplest form is 17/40.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
42.5%
= 42.5/100
= 425/1000
= 85/200
= 17/40

42.5% can be expressed as the fraction 17/40 in simplest form.
To express 42.5% as a fraction in the simplest form, we need to convert the percentage to a fraction with the numerator and denominator in their simplest form. Here's the step-by-step process:
Recognize that a percentage is a fraction out of 100. In this case, 42.5% can be written as 42.5/100.
Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 42.5 and 100 is 2. Dividing both the numerator and denominator by 2 gives us 21.25/50.
Continue simplifying the fraction by dividing both the numerator and denominator by any common factors. In this case, we can divide both by 25: 21.25/50 = 0.85/2.
Finally, express the fraction in simplest form by dividing both the numerator and denominator by their greatest common divisor, which is 5 in this case: 0.85/2 = 17/40.
Therefore, 42.5% can be expressed as the fraction 17/40 in simplest form.
This means that 42.5% is equivalent to 17 parts out of 40 parts.

It's C. The standard deduction is $1,613 better than Chris's deductions
I just took the test.
Answer:
(C)
Step-by-step explanation:
Chris's deductions for tax return = claim from property taxes +claim from medical expenses+claim form state income tax
= $1813+$1513+$761
= $4087
Standard deductions = $5700
Difference between standard deduction and Chris's deductions = 5700-408
= $1613
Hence standard deductions is better than Chris's deductions by $1613

There are 6 female goldfish for every 10 male goldfish in the aquarium. there are 216 female goldfish in the aquarium. how many male goldfish are in the aquarium?
Answers
cross multiply because we have a proportion
6m = (216)(10)
6m = 2160
m = 2160/6
m = 360...so when there are 216 females, there are 360 males.
If there are 6 female goldfish for every 10 male goldfish in the aquarium and if there are 216 female goldfish in the aquarium then there are 360 male goldfish in the aquarium.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Let us use a proportion to represent the relationship between the number of female and male goldfish in the aquarium
6 female goldfish / 10 male goldfish = 216 female goldfish / x male goldfish
We know that there are 216 female goldfish in the aquarium, so we can substitute that value into the equation:
6 / 10 = 216 / x
Let us solve for x by cross-multiply:
6x = 10 × 216
6x = 2160
Divide both sides by 6
x = 360
Therefore, there are 360 male goldfish in the aquarium.
