In economic theory, the price of a product is considered the independent variable, and the quantity of the product demanded by consumers is considered the dependent variable. As price (independent variable) increases, the quantity demanded (dependent variable) decreases.
Explanation:In the context of economics and specifically, the law of demand, the price of a commodity is the independent variable and the quantity demanded is the dependent variable. This means that the amount of a product that consumers are willing to buy (dependent variable) can change based on the price of the product (independent variable). If a price changes, if all other factors remain constant, the quantity demanded will react accordingly. For example, if the price of an item increases, the quantity demanded decreases because consumers are less willing to buy the item due to its high price. Conversely, if the price decreases, the quantity demanded increases because the product becomes more affordable to consumers.

Deon plans to ride a 15-mi bicycle trail. If his average is 20mi/h, with equation can he use to find the time T, in hours, for the ride ?
Distance traveled by Deon to ride a bicycle trail = 15 mile
Average speed of Deon to ride a bicycle trail = 20 mi/hour
Let 'T' be the time taken to ride the bicycle trail.
We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.
Distance =[tex]\frac{Speed}{time}[/tex]
[tex]15 = \frac{20}{T}[/tex]
So, [tex]T = \frac{20}{15}[/tex]
This equation will be used to find the time 'T' in hours for the ride.
Which statement is true?
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image.
A dilation is a function because the scale factor is always greater than 1.
A dilation is not a function because a point on the pre-image could be mapped to more than one point on the image.
A dilation is not a function because the image is not congruent to the pre-image.
Answer:
Dilation : The meaning of Dilation is that by taking a fixed center and certain real number we can either enlarge an image or reduce it's size without actually changing it's shape. it totally depends on amount by which we are dilating if it is a real number greater than 1 the size of image increases otherwise shrinks means smaller in size.
The original image is called Pre-image and after dilation that changed image is called image.
So, we can say that Dilation is a function because for each different scale factor or different real number we get different images.
So, Out of all the four options given first looks completely true about Dilation.
i.e A dilation is a function because every point on the pre-image corresponds to exactly one point on the image.
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image. This is the definition of a function in mathematics. The scale factor and the congruity of the image to the pre-image are irrelevant to the classification of dilation as a function.
Explanation:The correct statement is:
A dilation is a function because every point on the pre-image corresponds to exactly one point on the image
. In mathematics, dilation is a transformation that changes the size, but not the shape, of a figure. For a dilation to qualify as a function, each point in the pre-image must correspond to exactly one point in the image, without any point in the pre-image being mapped to more than one point in the image. This is the definition of a function: a relation from a set of inputs (the pre-image) to a set of possible outputs (the image) where each input is related to exactly one output. The scale factor and the congruity of the image to the pre-image have no bearing on whether a dilation is a function or not.

A music store sold 300cds and 100cd players. If each cd cost $12 and each cd player cost $35, what was the store total earnings
So with what we know we can set up two equations to solve for the CDs and the players.
$12(300) = total earnings for cds
= $3600 total cds sold
$35(100) = total earnings for cd players
=$35000
add both of the totals of the CDs and the CD players to get the total earnings
$3600+$3500 = $7100 gained in total from both products sold

A and B are not independent events because P(A|B)≠P(A) .
A and B are not independent events because P(A|B)=P(A) and P(B|A)=P(B) .
A and B are independent events because P(A|B)=P(B) and P(B|A)=P(A) .
A and B are not independent events because P(A|B)=P(B) and P(B|A)=P(A) .
Answer:
A and B are not independent events because P(A|B)≠P(A)
is the correct answer.
Step-by-step explanation:
If A and B are independent then we must have
P(AB) = P(A) P(B) and also
P(A/B) = P(A)
We are given that
A and B are two events.
Let P(A)=0.5 , P(B)=0.25 , and P(A and B)=0.15 .
P(A/B) = P(AB)/P(B) = 0.15/0.5 = 0.3
i.e. P(A/B) is not equal P(A)
Similarly P(B/A) = P(AB)/P(A) = 0.15/0.25 = 0.6 not equal to P(B)
Hence A and B are not independent.
Answer:

Write the perimeter of the floor plan shown as an algebraic expression in x.
Answer:
Perimeter = 2x + 64
Step-by-step explanation:
Perimeter = Sum of the lengths of the borders
From the given figure, we need to find the missing length.
Missing length = 18 - 10 = 8
Another missing length = (x + 14) - (x + 8) = x + 14 - x - 8
= 14 -8
= 6
Now let's add all the sides.
Perimeter = x + 14 + 8 + 6 + 10 + x + 8 + 18
Now add all the x terms and constants
Perimeter = 2x + 64
Find the sum of the polynomials (5y^3+2y^2-7y) + (12y^3-4y^2+8)
[tex](5y^3+2y^2-7y) + (12y^3-4y^2+8)\\\\=5y^3+2y^2-7y+12y^3-4y^2+8\\\\=(5y^3+12y^3)+(2y^2-4y^2)+(-7y)+(8)\\\\=17y^3-2y^2-7y+8[/tex]
Ryo accidentally ordered 240% percent as many eggs as his restaurant needs. What fraction of the number of eggs his restaurant needs did Ryo order?
Answer:
Ryo ordered [tex]\frac{12}{5}[/tex] of the number of eggs his restaurant needs.
Step-by-step explanation:
Suppose, the number of eggs his restaurant needs is [tex]x[/tex]
Ryo ordered 240% as many eggs as his restaurant needs. So, the number of eggs he ordered [tex]= x\times 240\% = x\times \frac{240}{100}= 2.4x[/tex]
For finding the fraction of the number of eggs his restaurant needs, we just need to divide "number of eggs ordered" by the "number of eggs needed".
So, the fraction will be: [tex]\frac{2.4x}{x}= 2.4 = \frac{24}{10}= \frac{12}{5}[/tex]
That means, Ryo ordered [tex]\frac{12}{5}[/tex] of the number of eggs his restaurant needs.
Ryo ordered 12/5 of the number of eggs his restaurant needs.
Given that Ryo accidentally ordered 240% percent as many eggs as his restaurant needs, to determine what fraction of the number of eggs his restaurant needs did Ryo order, the following calculation must be performed:
240/100 = X 10/24 = X 12/5 = X
Therefore, Ryo ordered 12/5 of the number of eggs his restaurant needs.

Which statement is false?
A. The number zero is a rational number.
B. Some irrational numbers are also rational numbers.
C. Every irrational number is a real number.
D. Every integer is a rational number.
Need answers ASAP, Thanks!
The false statement is B: 'Some irrational numbers are also rational numbers.' This is incorrect because a number cannot be both rational and irrational by definition.
The false statement among the options provided is option B: Some irrational numbers are also rational numbers. This is false because by definition, irrational numbers and rational numbers are distinct sets of numbers with no overlap. A rational number can be written as a ratio of two integers, which means it can be expressed as a fraction. On the other hand, an irrational number cannot be written as a ratio of integers. Thus, a number cannot be both rational and irrational at the same time.
To clarify the other options, option A is true because zero can be represented as the ratio 0/1, making it a rational number. Option C is true because irrational numbers such as π (pi) and √2 (the square root of 2) are indeed part of the set of real numbers. Option D is true because all integers can be expressed as a ratio where the denominator is 1, making every integer a rational number.

We are given
p: 1 is the multiplicative identity
Firstly, we will verify whether it is true
Multiplicative identity:
[tex]A \cdot 1=A[/tex]
Here , 1 is the multiplicative identity
So, 1 is multiplicative identity
so, statement p is true
q: a · 0 = a
we know that whenever we multiply any expression by 0
It will result in 0
so, this statement is false
now, we will verify each options
option-A:
p \/ q

T \/ F = T
so, this is TRUE
option-B:
p /\ q
so, we can plug
T /\ F = F
so, this is FALSE
option-C:
p --> q
we can plug
T-->F = F
so, this is FALSE
The statements p \/ q (p OR q) is true since the proposition p is true and hence the whole OR operation is true, p /\ q (p AND q) and p --> q (p implies q) are false since the proposition q is false.
Explanation:The given propositions are "p: 1 is the multiplicative identity" and q: a · 0 = a. Let's analyze each proposed relation among them:
p \/ q (p OR q): This is false. While p is true (since any number multiplied by 1 gives the same number), q is false (any number multiplied by 0 gives 0, not a). However, in an OR operation, if one statement is true, the whole statement is true. Hence, p \/ q is truep /\ q (p AND q): This is false. While p is true, q is false as explained earlier. In an AND operation both statements must be true for the whole statement to be true. Hence, p /\ q is falsep --> q (p implies q): This is false. In implication, if p is true, then q must be true.
