The equivalent ratios to 4/28 are obtained by dividing both the numerator and the denominator by 4 to get 1/7, and then by multiplying the resulting ratio to get the other two equivalent ratios, 2/14 and 3/21, which correspond to answer choice b.
Explanation:The question is asking to write three ratios that are equivalent to the ratio 4/28. To find equivalent ratios, you can either multiply or divide both the numerator (top number) and the denominator (bottom number) of a ratio by the same non-zero number.
For the ratio 4/28, if we divide both the numerator and the denominator by 4, we get 1/7. If we then multiply 1/7 by different numbers, we can find additional equivalent ratios. Therefore, multiplying by 2 gives us 2/14, and multiplying by 3 gives us 3/21. This means that the set of equivalent ratios is 1/7, 2/14, 3/21, which corresponds to answer choice b.

For the demand equation, express the total revenue R as a function of the price p per item.
q = −5p + 500
R(p) = ?
The total revenue (R) can be expressed as a function of the price (p) per item by multiplying the price by the quantity demanded (q). Given the demand equation q = -5p + 500, the total revenue equation is R(p) = -5p^2 + 500p.
Explanation:The total revenue (R) can be expressed as a function of the price (p) per item by multiplying the price by the quantity demanded (q).
Given the demand equation q = -5p + 500, we can substitute q in the total revenue equation with -5p + 500:
R(p) = p * (-5p + 500)
Simplifying, we distribute p to both terms inside the parenthesis:
R(p) = -5p^2 + 500p
So, the total revenue (R) as a function of price (p) is R(p) = -5p^2 + 500p.

(3x − 4) feet
(4x − 3) feet
(4x + 3) feet ...?
Answer: The correct option is (B) [tex](3x-4).[/tex]
Step-by-step explanation: Given that Sam decides to build a square garden whose area is as follows:
[tex]A=9x^2-24x+16~\textup{square feet}.[/tex]
We are to find the length of one side of the garden.
Since the given garden is of a square shape, so the length of each side is same.
That is, the area of the garden must be a perfect square trinomial.
We have
[tex]A\\\\=9x^2-24x+16\\\\=(3x)^2-2\times 3x\times 4+4^2\\\\=(3x-4)^2.[/tex]

"Which of the following are remote interior angles of 5? Check all that apply.
A.1
B.2
C.3
D.4
E.5
F. 6"
Answer:
A. 1
B. 2
Step-by-step explanation:
We have been given an image of a triangle. We are asked to find remote interior angles of angle 5 for our given triangle.
We can see that angle 5 is an exterior angle. We know that remote interior angles are those, which are inside the triangle and opposite to exterior angle.
We can see that angle 2 and angle 1 are are opposite angles of angle 5 and they are inside our given triangle.
Therefore, option A and B are correct choices.
Final answer:
Remote interior angles are non-adjacent angles within the same triangle. Relative to angle 5, angle 1 and angle 2 are remote interior angles because they are inside the triangle and do not share a vertex with angle 5.
Explanation:
In this mathematics problem, we are asked to find the remote interior angles of a given angle, which are angles that are inside the triangle and non-adjacent to the exterior angle being considered. For example, if we have a triangle with angles labeled 1, 2, 3, 4, 5, and 6, and we want to find the remote interior angles relative to angle 5, we would look for the angles inside the triangle that do not share a vertex with angle 5.
From the available options:
Angle 1 and angle 2 qualify as remote interior angles relative to angle 5 because they are non-adjacent to angle 5 and are within the same triangle.Angle 3 is adjacent to angle 5, so it is not a remote interior angle.Angles 4, 5, and 6 are not pertinent in this case because the question is specifically about the remote interior angles of angle 5, making angles 4 and 6 external to the triangle, whereas angle 5 is the angle in question itself.Therefore, options A (1) and B (2) are the correct answers to this problem.

Determine the value c so that each of the following
functions can serve as a probability distribution of
the discrete random variable
X:(a)
f(x) =c(x2+ 4), for x= 0,1,2,3;
(b)f(x) =c(choose x from2)(choose 3 from 3-x) for x= 0,1,2.
The value of c, which must be determined for a discrete random variable to serve as a probability distribution, should be 1/30 for the function f(x) = c(x^2 + 4) and 1/3 for the function f(x) = c(choose 2 from x)*(choose 3 from 3-x).
Explanation:The value of c for a probability distribution needs to be determined such that the total sum of the probabilities is equal to 1. For this, we need to calculate the sum of all possible outcomes and then normalize it to 1.
For the function f(x) = c(x2 + 4), where x = 0, 1, 2, 3, the total sum of the outcomes without the multiplying factor, c, is (02+4) + (12+4) + (22+4) + (32+4) = 4 + 5 + 8 + 13 = 30. The factor c then must be 1/30 for the probabilities to sum up to 1.For the function f(x) = c(choose 2 from x)*(choose 3 from 3-x), where x = 0, 1, 2, the total sum of outcomes without c is (choose 2 from 0)*(choose 3 from 3) + (choose 2 from 1)*(choose 3 from 2) + (choose 2 from 2)*(choose 3 from 1) = 0 + 0 + 3 = 3. Therefore, the factor c for this function must be 1/3.Learn more about Probability Distribution here:https://brainly.com/question/14210034

The student's question involves counting the number of spirals in a cactus, which corresponds to two consecutive numbers in the Fibonacci sequence. The exact answer would depend on the actual count, which cannot be determined without the photograph.
Explanation:The question asks about the phenomenon related to the Fibonacci sequence observed in natural patterns, specifically in plant architecture such as cacti spirals. The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. It is often observable in nature, for example, in the arrangement of leaves or the spirals on sunflower heads and cacti.
In order to answer the question, one would need to physically count the number of left-handed and right-handed spirals on the cactus. The Fibonacci sequence relevant to this context begins with 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, and so on. Since the given answer choices are consecutive terms from this sequence, the correct numbers would be identified based on the actual spiral counts which are expected to be consecutive Fibonacci numbers.
Without the photograph, it is impossible to provide the specific numeric answer, but we can understand that the two numbers representing the left-handed and right-handed spirals on the cactus would be consecutive Fibonacci numbers as indicated by the options provided: A) 34 and 55, B) 5 and 8, C) 8 and 13, D) 21 and 34, e) 13 and 21.

bulbs, and six 75-W bulbs. If bulbs are se-
lected one by one in random order, what is
the probability that at least two bulbs must be
selected to obtain one that is rated 75W?
Answer: 0.99483
Step-by-step explanation:
Given : A box contains four 40-W bulbs, five 60-W bulbs, and six 75-W bulbs.
Total bulbs : 4+5+6=15
The probability of selecting a 75-W bulb :[tex]p=\dfrac{6}{15}=0.4[/tex]
Using the binomial probability :-
[tex]P(X)= ^nC_xp^x(1-p)^{n-x}[/tex], where P(x) is the probability of getting success in x trials , p is the probability of getting success in each trial and n is the total number of trials.
We have,
The probability that at least two bulbs must be selected to obtain one that is rated 75W :-
[tex]P(x\geq2)=1-(P(x<2))\\\\=1-(P(x=0)+P(x=1))\\\\=1-(^{15}C_0(0.4)^0(0.6)^{15}+^{15}C_{1}(0.4)^1(0.6)^{14})\\\\=1-((1)(0.6)^{15}+(15)(0.4)(0.6)^{14})\ \ [\because\ ^nC_0=1\ \&\ ^nC_1=n]\\\\\approx1-(0.00047+0.00470)\\\\=1-0.00517=0.99483[/tex]
Hence, the required probability = 0.99483
A rancher with 750 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle.
1] Find a function that models the total area of the four pens. (Let w be the width of the rectangular area and A(w) be the area.)
2]Find the largest possible total area of the four pens. (Round your answer to one decimal place.)
The function modeling the total area of the four pens is [tex]A(w) = w * ((750 - 3w) / 2)[/tex]. The maximum area can be found by taking the derivative of this function, setting it to zero, and solving for w.
Explanation:The subject in question is Mathematics, specifically calculus and problem-solving involving areas. The rancher with 750 ft of fencing intends to make a rectangular area divided into four pens. Let's define w to be the width and l to be the length of the rectangle.
1] Since the total length of the fence is 750 ft and it will be divided into 3 parts for the width and 2 parts for the length, the function for calculating length will be [tex]l = (750 - 3w) / 2[/tex]. Since the area of a rectangle is given by A=w*l, we can substitute our equation for l into our Area function. Therefore, our function will be [tex]A(w) = w * ((750 - 3w) / 2).[/tex]
2] To find the maximum area of the rectangles, you would need to find the derivative of the Area function and solve for w. After that, plug the value of w into the area function to get maximum area. The exact calculation requires calculus skills and could be taught in a high school Calculus course.

Given the function g(x) = 4x - 5, compare and contrast g(2) and g(-4). Choose the statement that is true concerning these two values.
Answer
The value of g(2) is smaller than the value of g(-4).
The values of g(2) and g(-4) cannot be compared.
The value of g(2) is larger than the value of g(-4).
The value of g(2) is the same as the value of g(-4). ...?
By substituting the x-values into the linear function g(x) = 4x - 5, we find g(2) = 3 and g(-4) = -21. Therefore, the value of g(2) is larger than the value of g(-4).
Explanation:To determine the values of g(2) and g(-4) for the function g(x) = 4x - 5, we simply substitute the x-values into the function.
For g(2):
g(2) = 4(2) - 5g(2) = 8 - 5g(2) = 3For g(-4):
g(-4) = 4(-4) - 5g(-4) = -16 - 5g(-4) = -21Now, we can compare the two values:
The value of g(2), which is 3, is larger than the value of g(-4), which is -21.
The statement that is true concerning [tex]\( g(2) \)[/tex] and [tex]\( g(-4) \)[/tex] is option a) : The value of [tex]\( g(2) \)[/tex] is larger than the value of [tex]\( g(-4) \)[/tex].
To compare and contrast [tex]\( g(2) \)[/tex] and [tex]\( g(-4) \)[/tex] for the function [tex]\( g(x) = 4x - 5 \)[/tex]:
1. Calculate [tex]\( g(2) \)[/tex] :
[tex]\[ g(2) = 4 \cdot 2 - 5 = 8 - 5 = 3 \][/tex]
2. Calculate [tex]\( g(-4) \)[/tex] :
[tex]\[ g(-4) = 4 \cdot (-4) - 5 = -16 - 5 = -21 \][/tex]
Now, let's analyze the values:
- [tex]\( g(2) = 3 \)[/tex]
- [tex]\( g(-4) = -21 \)[/tex]
Comparing these values:
- [tex]\( g(2) \)[/tex] is positive (3).
- [tex]\( g(-4) \)[/tex] is negative (-21).
Therefore, [tex]\( g(2) \)[/tex] is greater than [tex]\( g(-4) \)[/tex]. This means:
[tex]\[ \text{The value of } g(2) \text{ is larger than the value of } g(-4). \][/tex]
Explanation:
The function [tex]\( g(x) = 4x - 5 \)[/tex] calculates a linear relationship where [tex]\( g(2) \)[/tex] evaluates to 3 and [tex]\( g(-4) \)[/tex] evaluates to -21. This comparison clearly shows that [tex]\( g(2) \)[/tex] yields a larger value than [tex]\( g(-4) \)[/tex]. This result stems from the fact that when x = 2 , [tex]\( g(x) \)[/tex] outputs a positive value, while for x = -4 , [tex]\( g(x) \)[/tex]outputs a larger negative value. Therefore, option:
Complete question : Given the function g(x) = 4x −5, compare and contrast g(2) and g(−4). Choose the statement that is true concerning these two values.
a The value of g(2) is larger than the value of g(−4).
b The value of g(2) is smaller than the value of g(−4).
c The value of g(2) is the same as the value of g(−4).
d The values of g(2) and g(−4) cannot be compared.
