Step-by-step explanation:
Given
Joe
\(Start = 18\)
\(Additional = 3\)
Mark
\(Start = 28\)
\(Additional = 3\)

Determine which option answers the question
From the question, we have that Mark and Joe have the same additional rule of increment.
This implies that, the difference of each term is the same as the difference of the starting number of both:
Since Mark started at a higher number than Joe, the difference can be said to be.
\(Difference = Start_{Mark} - Start_{Joe}\)
\(Difference = 28 -18\)
\(Difference = 10\)

Answers
Since g(-x) is equal to g(x), the function is an EVEN FUNCTION.
Is the given function even, odd or neither?Given the function in the question;
g(x) = (4 + x²)/(1 + x⁴)
To determine if the function is even, odd or neither, we find g(-x) by substituting -x for all occurrence of x in the function.
g(x) = (4 + x²)/(1 + x⁴)
g(-1) = (4 + (-x)²)/(1 + (-x)⁴)

a) How many cupcakes dud Patricia bake?
b) She sold all the small boxes and collected $189. How much did she sell each small box for?
Answers
Answer:
The answer is given below
Step-by-step explanation:
a)
Let us assume Patricia baked x number of cakes. She put half of the cupcakes (i.e x/2) equally into 6 big boxes.
6 big boxes contained \(\frac{x}{2}\) cakes, therefore 1 big box would contain \(\frac{x}{2}/6=\frac{x}{12}\) cakes.
Let us assume she put the other half into 14 small boxes, therefore each small box would contain \(\frac{x}{2}/14=\frac{x}{28}\) cakes.
There were 45 cupcakes in 3 big boxes and 8 small boxes altogether. That is:\(3(\frac{x}{12} )+8(\frac{x}{28})=45\\ 84x+96x=15120\\180x=15120\\x=84\)
Therefore Patricia baked 84 cup cakes
b)
She sold all the small boxes and collected $189, i.e she sold 14 small box for $189. Each small box = $189/14 = $13.5

Many unversities and colleges have instituted supplemental instruction (SI) programs, in which student facilitator meets regularly with a small group of students enrolled in the course to promote discussion of course material and enhance subject mastery. Suppose that students in a large statistics course are randomly divided into a control group group that will not participate in SI and a treatment group that will participate. At the end of the term each student’s total score in the course is determined.
A) Are the scores from the SI group a sample from an existing population? If so, what is it? If not, what is the relevant conceptual population?
B) What do you think is the advantage of randomly dividing the students into the two groups rather than letting each student choose which group to join?
C) Why didn’t the investigators put all students in the treatment group?
Answers
Answer:
Step-by-step explanation:
SUPPLEMENTAL INSTRUCTION PROGRAMS
- Students in a large statistics course are randomly divided into a control group and an experimental/treatment group. At the end of the term, each student's score in the course is examined
(A) The scores from the SI (Experimental) group are not a sample from an existing population. They are data from a group in a sample, hence the sample here is the number of students tested in this experiment and that equates to all the students in the large Statistics course/class.
- The relevant conceptual population would be all students in the university, since the general purpose or statement of this experiment is to see the effect of SI programs implemented in universities.
(B) The advantage of the random (unintentional) division of the students into control and experimental groups is that results or scores from the groups will be unbiased.
If you let each student choose a group, there is a high probability that the serious students will all join the SI group while the unserious ones will choose to be in the control group.
There is also a high probability that brilliant/pompous students will ignore the supplemental instruction program while students with low and medium intelligence quotient (IQ) will embrace it.
It is also possible that students will join whatever group their friends join.
These and other biases will defeat the aim of the experiment.
(C) The investigators didn't put all students in the sample into the experimental group because the difference or impact of the SI program needs to be known; whether positive or negative. Dividing them into the 2 groups lets the investigators know if there is a difference in the scores of students in the two groups.

Answers
The coordinates of midpoint P are P(-1/2, 3/2) and coordinates of midpoint Q are Q(-3/2, -4).
To find the coordinates of the midpoints P and Q of sides AB and AC, we can use the midpoint formula.
The midpoint formula states that the coordinates of the midpoint of a line segment between two points (x1, y1) and (x2, y2) are given by:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
Using this formula, we can find the coordinates of P and Q as follows:
Coordinates of midpoint P:
P = ((2 + (-3)) / 2, (-1 + 4) / 2)
= (-1/2, 3/2)
Therefore, the coordinates of midpoint P are P(-1/2, 3/2).
Coordinates of midpoint Q:
Q = ((2 + (-5)) / 2, (-1 + (-7)) / 2)
= (-3/2, -4)
Therefore, the coordinates of midpoint Q are Q(-3/2, -4).

Answers
The statement that is true regarding the function f(x) = (x-4)(x + 1) is that the function is increasing for all real values of x where x < -1 and where x > 4. So, the option is: O The function is increasing for all real values of x where x < -1 and where x > 4.
Explanation: Given function is:f(x) = (x - 4) (x + 1). The graph of the given function is shown below: As it is visible from the graph, the function is decreasing for all real values of x where x lies between -1 and 4 (inclusive).
The turning point of the function is x = -0.5, which is the x-coordinate of the vertex of the parabola. Also, we see that the vertex is the minimum point of the parabola and the y-coordinate of the vertex is -4.25. This means that f(x) ≥ -4.25 for all x. The function is increasing for all real values of x where x < -1 and where x > 4.

68 times the difference between a number and 45 is equal to the number plus −98
Answers
Answer:
The number can be expressed in multiple forms
Fraction form \(x=\frac{2962}{67}\) or decimal form \(x=44.21\)
Step-by-step explanation:
Lets break the problem down
"times" is multiplication *
The difference between 2 numbers is subtraction \((x-y)\)
A number plus a number is addition \(x+y\)
\(68(x-45)=x+-98\)
Lets solve for \(x\).
Lets start on the left side.
Distribute 68 to the terms inside the parenthesis.
\(68x-3060=x+-98\)
A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign.
\(68x-3060=x-98\)
Subtract \(x\) from both sides of the equation.
\(68x-3060-x=-98\)
Subtract \(x\) from \(68x\).
\(67x-3060=-98\)
Add 3060 to both sides of the equation.
\(67x=2962\)
Divide both sides of the equation by 67.
\(x=\frac{2962}{67}\) or as a decimal \(x=44.21\)

Divide: 7 5/6 ÷ 2/3 need help
Answers
To divide a mixed number by a fraction, we need to convert the mixed number into an improper fraction and then multiply it by the reciprocal of the fraction.
Step 1: Convert the mixed number to an improper fraction:
7 5/6 = (6 * 7 + 5) / 6 = 47/6
Step 2: Multiply the improper fraction by the reciprocal of the fraction:
47/6 ÷ 2/3 = 47/6 * 3/2
Step 3: Simplify the fraction if possible:
47/6 * 3/2 = (47 * 3) / (6 * 2) = 141/12
Step 4: Simplify the fraction further, if necessary:
141/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 3:
141/12 = (141 ÷ 3) / (12 ÷ 3) = 47/4
Therefore, 7 5/6 ÷ 2/3 is equal to 47/4 or 11 3/4.

The Maximum Area of the fence is 10000 square feet
SOLUTION
Problem Statement
The question tells us the fence is made of 400 feet of material and we are asked to calculate the maximum area that can be enclosed by the fencing.
Method
- Let the length and breadth of the rectangle be x and b. Thus, we can write out an expression for the perimeter of the fence as follows:
\(\begin{gathered} 2(x+b)=400 \\ \text{Divide both sides by 2} \\ x+b=\frac{400}{2}=200 \\ \\ \therefore x+b=200\text{ (Equation 1)} \end{gathered}\)- Also, we can write out the Area enclosed by the fence as follows:
\(\begin{gathered} A=x\times b \\ A=xb\text{ (Equation 2)} \end{gathered}\)Implementation
- For this stage, we shall work on the two Equations we arrived at during our analysis in the Method stage.
- We shall try to write the function of the Area in terms of x. Once this is done, we shall proceed to differentiate this function of A with respect to x.
- The differentiation describes how the Area of the plot surrounded by the fence changes with its length x.
- At maximum Area, this change will be equal to zero because any other change would be a decrease in the area of the plot.
- We shall complete the solution by finding the value of x for which the Area is maximum, finding the corresponding value of breadth, b, and then finding the Maximum Area of the plot using the formula for the Area given above.
- We can break this process down into the following steps:
1. Find the Area function in terms of x alone
2. Differentiate the Area function.
3. Equate to zero and find x.
4. Find the value of b and the Maximum Area.
Now, we can solve as follows:
1. Find the Area function in terms of x alone
\(\begin{gathered} x+b=200\text{ (Equation 1)} \\ A=xb\text{ (Equation 2)} \\ \\ \text{From Equation 1,} \\ b=200-x \\ Substitute\text{ this expression for b into Equation 2} \\ \\ A=x(200-x) \\ A=200x-x^2 \end{gathered}\)2. Differentiate the Area function
\(\begin{gathered} A=200x-x^2 \\ \text{Differentiating A with respect to x, we have:} \\ \mathrm{\frac{dA}{dx}}=\mathrm{\frac{d}{dx}}(200x-x^2) \\ \\ \mathrm{\frac{dA}{dx}}=\mathrm{\frac{d}{dx}}(200x)-\mathrm{\frac{d}{dx}}(x^2) \\ \\ \mathrm{\frac{dA}{dx}}=200-2x \end{gathered}\)3. Equate to zero and find x:
\(\begin{gathered} \mathrm{\frac{dA}{dx}}=200-2x \\ At\text{ maximum Area, }\mathrm{\frac{dA}{dx}}=0 \\ \\ 200-2x=0 \\ \therefore2x=200 \\ \text{Divide both sides by }2 \\ \frac{2x}{2}=\frac{200}{2} \\ x=100 \end{gathered}\)4. Find the value of b and the Maximum Area:
\(\begin{gathered} \text{ We find the value of b by substituting the value of }x\text{ into the Perimeter equation, Equation 1.} \\ x+b=200 \\ 100+b=200 \\ \text{subtract 100 from both sides} \\ b=200-100 \\ \therefore b=100 \\ \\ \text{Thus, the maximum area is:} \\ A=xb=100\times100 \\ \therefore A=10000 \end{gathered}\)Final Answer
The Maximum Area of the fence is 10000 square feet
5/8 entre 6 personas
Answers
Based on the information we can infer that 5/8 between 6 people is equal to 15/24.
How to divide 5/8 between 6 people?To calculate the part that corresponds to each person, divide the fraction 5/8 by the number of people, which in this case is 6. To simplify the fraction, you can reduce the numerator and denominator by dividing both by their maximum common factor, which is 3.
5 ÷ 3 = 1 and 2 remainder8 ÷ 3 = 2 and 2 remainder
So the fraction can be simplified to 1 2/8, which can also be expressed as 1 1/4 or 5/4 in its most simplified form. This means that each person would receive 5/4 of the original share, and since there are 6 people in total, you can multiply 5/4 by 6 to get the total share that corresponds to all 6 people:
(5/4) x 6 = 30/4 = 15/2 = 15/24
So each person would receive 15/24 of the original amount.

1st Group DATA:
rate = 10 km/h ; distance = x km ; time = d/r = x/10 hrs
Two hours later, the other group leader left the campsite in a motorboat.
He traveled at an average rate of 22 km/h.
Group Leader DATA:
rate = 22 km/h ; distance = x km ; time = d/r = x/22 hrs
A. How long after the canoe left the campsite did the motorboat catch up with it?
Group time - Leader time = 2 hr
x/10 - x/22 = 2
Multiply thru by 110 to get:
11x - 5x = 220
