Proportional relationships are relationships with equal ratio. Mandy's conclusion is incorrect because the relationship is proportional, and it has a uniform ratio of 5.
To determine if the input and output are proportional, we simply divide the output (y) by the corresponding input (x).
i.e.
[tex]Ratio = \frac yx[/tex]
So, we have:
[tex]Ratio = \frac 51 = 5[/tex]
[tex]Ratio = \frac{10}{2} = 5[/tex]
[tex]Ratio = \frac{25}{5} = 5[/tex]
[tex]Ratio = \frac{50}{10} = 5[/tex]
For the four input and output data, the ratios are equal (i.e. 5).
This means that the relationship is proportional.
Hence, Mandy's conclusion is incorrect

Mandy is correct about the proportional relationship as all the ratios of y to x in her table are equivalent to 5/1. However, there is an error with the last ratio listed as 10/50, which should be 50/10 to match the information in the table. After correcting this typo, it is clear that the relationship is proportional because all of the ratios simplify to the same value.
Explanation:Mandy is indeed correct. For a set of ratios to represent a proportional relationship, they all must have the same value when simplified. From Mandy's table, the ratios formed from the inputs (x) and outputs (y) are 5/1, 10/2, 25/5, and 50/10. When simplified, these should give us a constant ratio if the relationship is proportional. Simplifying the ratios, we get:
5/1 simplifies to 5/110/2 simplifies to 5/125/5 simplifies to 5/150/10 simplifies to 5/1Since all ratios simplify to the same number, 5/1, it indicates that the relationship between x and y is indeed proportional. However, the last ratio listed in the question, 10/50, is incorrect as it should be 50/10 to maintain consistency with the rest of the table. If we correct this ratio to 50/10, then all ratios confirm a proportional relationship.
To further validate this, a proportion can be created by setting two ratios equal to each other. For example, we can compare the first and the second ratio: 5/1 = 10/2. When you cross-multiply, the resulting equations, 5*2 = 10*1, are true, again confirming proportionality.

the sum of four consecutive integers os -18. what is the greatest of these integers?
Answer:
-3
Step-by-step explanation:
-3+(-4)+(-5)+(-6)=-3-4-5-6=-18
-3 is the greatest because the smaller the number behind the negative sign, the larger the number that's larger than that but behind a negative sign is smaller. e.g. -4 is less than -3

The sum of 4 consecutive even integers is 20. what are the integers?
The given four consecutive even integers are 2, 4, 6, 8
What are even numbers and how can we write consecutive even numbers?Even numbers are numbers which are divisible by two.
Any even number can be written as 2n , where n is any integer
If we increase n by 1 then next even number will be obtained. Then the consecutive even numbers be 2n , 2 (n+1), 2(n +2) , 2 (n+3), ....... so on.
Given that the sum of four consecutive even integers is 20
Let the four consecutive even integers are :
2n , 2(n+1) , 2(n+2), 2( n+3)
Then
⇒2n + 2(n+1) + 2(n+2) + 2( n+3) = 20
⇒ 2n + 2n +2 +2n +4 + 2n +6 =20
⇒ 8n + 12 =20
⇒ 8n = 20-12
⇒ 8n = 8
⇒ n =8/8 = 1
Therefore, the given four consecutive even integers are 2, 4, 6, 8

the product of the binomial by the trinomial is [tex]y^3+27[/tex].
Step-by-step explanation:
Binomial is the term having two different term and trinomial having three different terms.
Here, Binomial is [tex]y+3[/tex] and trinomial is [tex]y^2-3y+9[/tex]
We have find the product of the binomial by the trinomial.

A dreidel is a top with four sides, used in a Hanukah game. The sides are labeled with the Hebrew letters, nun, gimel, hay, and shin. A dreidel is spun 100 times, with the following results: nun 10 gimel 45 hay 24 shin 21 A player wins tokens if the dreidel lands on either gimel or hay. What is the probability of winning tokens? a. 0.54 c. 0.69 b. 0.63 d. 0.87
The probability of winning tokens is 0.69. Therefore, the option C is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.
Given that, dreidel is spun 100 times, with the following results: nun =10, gimel =45, hay =24 and shin =21.
A player wins tokens if the dreidel lands on either gimel or hay.
Here, probability of getting gimel is 45/100
The probability of getting hay is 24/100
So, the probability of an event is 45/100 +24/100
= 69/100
= 0.69
Therefore, the option C is the correct answer.

A rectangular field is nine times as long as it is wide. If the perimeter of the field is 1600 feet, what are the dimensions of the field?
Final answer:
The width of the field is 80 feet, and the length is 720 feet, calculated using the perimeter formula and the given ratio of length to width.
Explanation:
To determine the dimensions of the rectangular field, we need to set up two equations based on the given information that the field's length is nine times its width and that the perimeter is 1600 feet. We'll let w represent the width of the field and l represent the length.
Since the field's length is nine times its width, we can express this as l = 9w. The perimeter P of a rectangle is given by P = 2l + 2w. Since we know the perimeter is 1600 feet, we can use this to create the equation 1600 = 2(9w) + 2w, which simplifies to 1600 = 18w + 2w.
Combining like terms gives us 1600 = 20w, and solving for w gives us w = 1600 / 20, so w = 80 feet. Knowing w, we can find l by multiplying the width by 9: l = 9w = 9 × 80 = 720 feet.
Therefore, the dimensions of the field are a width of 80 feet and a length of 720 feet.

Which statement describes the translation of . y= -1/2(x-2) ^2 from standard position? A) Moved up and to the right. B) Moved up and to the left. C) Moved down and to the left. D) Moved down and to the right. .
Answer: The correct option is
(D) Moved down and to the right.
Step-by-step explanation: We are given to select the statement that best describes the translation of the following function from the standard position.
[tex]y=-\dfrac{1}{2}(x-2)^2~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
This is an equation of a parabola.
The standard position of a parabola of this type is
[tex]y=x^2,[/tex]
where the vertex is at (0, 0). Since the coefficient of x² is positive, so the parabola opens upwards.
Now, from equation (i), we have
the vertex of the parabola is at (2, 0) and since the coefficient of x² is negative, so the parabola opens downwards.
Also, the vertex (0, 0) has been shifted to (2, 0), so the parabola is moved 2 units to the right.
Therefore, the given parabola is moved down and 2 units to the right as compared to the standard position.
The images of the given parabola (i) and the standard parabola are shown in the attached figure below.
Thus, (d) is the correct option.

Which is a stretch of an exponential decay function? f(x) = 4/5(5/4)^x f(x) =4/5(4/5)^x f(x) =5/4(4/5)^x f(x) =5/4(5/4)^x
Answer:choice three
Step-by-step explanation:
Answer:
The correct option is 3. The function [tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex] is a stretch of an exponential decay function.
Step-by-step explanation:
The general form of an exponential function is
[tex]f(x)=ab^x[/tex]
where, a is the initial value and b is the growth factor.
If b<1, then it represents a decay function and if b>1, then it represents a growth function.
Let k be a stretch and compression factor.
[tex]g(x)=kf(x)[/tex]
If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.
In third function
[tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex]
[tex]k>1[/tex]
[tex]b<1[/tex]
Therefore the function [tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex] is a stretch of an exponential decay function.
