Final answer:
The relationship between the mean and median margin of victory in a right-skewed distribution is explained.
Explanation:
The relationship between the mean and median margin of victory in this case defines a right-skewed distribution. In a skewed distribution, the mean tends to be farther out on the tail compared to the median. This is because in a right-skewed distribution, there are a few large values that pull the mean towards the right and away from the median, which represents the middle value. In this case, the mean margin of victory is 88.2, and the median margin of victory is 87.5. Therefore, the correct answer is option A) skewed to the right.

Mario wants to put a rectangular fence around the pool in his backyard. Since one side is adjacent to the house, he will only need to fence three sides. There is one long side parallel to the house, and two shorter sides. He needs 130 feet of fencing to enclose the pool. The length of the long side is 10 feet less than twice the width. Find the length and width of the pool area to be enclosed.
Answer:
The length and width of the pool area is:
Length = 60 feet. Width = 35 feet.Step-by-step explanation:
Since the 130-foot fence should enclose only three parts of the pool (two wide and one long), equations are performed to express the information provided.
First an equation that says the total feet in the fence:
X + 2Y = 130 (where X is the length and Y is the width) X = 2Y-10 (since the length is 10 feet less than twice the width)With these equations, we proceed to replace the second equation in the first one and solve for Y:
X + 2Y = 130 2Y -10 + 2Y = 130 4Y - 10 = 130 4Y = 130 + 10 Y = 140/4 Y = 35 feetSince we already know that the width corresponds to 35 feet, we use the second equation to find the value of X:
X = 2Y-10 X = 2 (35) -10 X = 70 - 10 X = 60With which it is identified that the length is 60 feet.
To find the dimensions of the pool area, we can set up an equation using the given information. Solving the equation, we find that the width of the pool area is 35 feet and the length is 60 feet. Therefore, the dimensions of the pool area to be enclosed are 35 feet by 60 feet.
Explanation:To find the dimensions of the pool area, we will set up an equation based on the given information. Let's say the width of the pool area is 'w'. According to the problem, the length of the long side is 10 feet less than twice the width, so the length can be represented as 2w - 10. Since Mario needs to fence three sides, we can calculate the total length of the fence as follows:

Solve the equation for y. yp+yn=x
This is tricky because it has a lot of variables, but we just have to treat this problem normally.
[tex]yp+yn=x[/tex]
separate y from p + n (feel free to check that you can do this by multiplying y out again and seeing that we have the same thing as before)
[tex]y(p+n)=x[/tex]
divide p + n on both sides
[tex]y = \frac{x}{p+n}[/tex]
Answer:
[tex]y = \frac{x}{p+n}[/tex]
To solve the equation yp + yn = x for y, factor out y to get y(p + n) = x, then divide both sides by (p + n) to isolate y, resulting in y = x / (p + n).
To solve the equation yp + yn = x for y, you need to factor y out of the left side of the equation.
This gives you y(p + n) = x.
To isolate y, you then divide both sides of the equation by (p + n), assuming p + n
eq 0, to get y = x / (p + n).

Find the equation of the line passing through the given point and perpendicular to the given equation write your answer in slope intercept form. (3,4) and y= -4/9x-3
Answer:
Step-by-step explanation:
To find the slope of a line perpendicular to y = (-4/9)x - 3, take the negative reciprocal of this slope -4/9. The slope of the new line is thus 9/4.
Now we have this data to work with: m = 9/4, y = 4 and x = 3. Subbing this info into y = mx + b, to obtain the value of b, we get:
4 = (9/4)(3) + b, or
4 = 3/4 + b. Thus, b = 3 1/4, or b = 13/4.
The desired equation is
y = (9/4)x + 13/4.
the second of two numbers is 3 less than twice the first. Their sum is 36. Find the numbers.
Answer:

If your target number of calories is 1700 per day to lose weight, but you are consuming 2500 calories per day. Then, your target is to consume what percent of the calories you are consuming?
Answer:
32%
Step-by-step explanation:
We have been given that your target number of calories is 1700 per day to lose weight, but you are consuming 2500 calories per day.
First of all, we will find number of calories you should eat to lose weight by subtracting 1700 calories from 2500 calories.
[tex]2500-1700=800[/tex]
Now, we will find 800 is what percent of 2500.

$272. Ryan solf 11 rolls of plain and 16 rolls of holiday wrapping paper for a total $359. What is the cost of one
roll of plain wrapping paper and one roll of holiday wrapping paper?
Answer:
Cost of one roll of plain wrapping: [tex]\$5[/tex]
Cost of one roll of holiday wrapping paper: [tex]\$19[/tex]
Step-by-step explanation:
Let be "p" the cost in dollars of one roll of plain wrapping paper and "h" the cost in dollars of one roll of holiday wrapping paper.
Based on the information given, we can set up this system of equations:
[tex]\left \{ {{5p+13h=272} \atop {11p+16h=359}} \right.[/tex]
In order to solve it, we can use the Substitution method. The steps are:
1. Solve for "p" from the first equation:
[tex]5p+13h=272\\\\5p=272-13h\\\\p=\frac{272-13h}{5}[/tex]
2. Substitute the above into the second equation and solve for "h":
[tex]11(\frac{272-13h}{5})+16h=359\\\\598.4-28.6h+16h=359\\\\-12.6h=359-598.4\\\\h=\frac{-239.4}{-12.6}\\\\h=19[/tex]
3. Substitute the value of "h" into [tex]p=\frac{272-13h}{5}[/tex]:
[tex]p=\frac{272-13(19)}{5}\\\\p=5[/tex]

the price of the shirt and y represent the price of the pants. Write an equation
that can be used to find the price of the shirts and pants.
Directions: Write the equation in both slope-intercept and standard form for each of the
scenarios below.
Using the Standard Form, identify the x-intercept of the graph and explain
how the x-intercept relates to the price of the pants and shirts.
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the price of the shirt
y ---> he price of the pants
we have that
The price of three shirts plus the price of two paints must be equal to $300
so
[tex]3x+2y=300[/tex]
This is the equation of the line in standard form
Convert to slope intercept form
[tex]y=mx+b[/tex]
Isolate the variable y
[tex]3x+2y=300[/tex]
subtract 3x both sides
[tex]3x+2y-3x=-3x+300[/tex]
[tex]2y=-3x+300[/tex]
Divide by 2 both sides
[tex]y=-1.5x+150[/tex] ----> equation of the line in slope intercept form
Find out the x-intercept
Remember that the x-intercept is the value of x when the value of y is equal to zero
In this problem, the x-intercept is the price of the shirt when the price of the paints is equal to zero
Using the Standard Form, identify the x-intercept of the graph
The standard form is
[tex]Ax+By=C[/tex]
The x-intercept is C/A
we have
[tex]3x+2y=300[/tex]
so
[tex]300/3=100[/tex]
The x-intercept is the point (100,0)
That means---> The price of the shirt is $100 when the price of the paints is equal to $0
Alternative method to find out the x-intercept (equation in slope intercept form)
[tex]y=-1.5x+150[/tex]
For y=0
[tex]0=-1.5x+150[/tex]
solve for x
[tex]1.5x=150[/tex]
[tex]x=\$100[/tex]
The x-intercept is the point (100,0)

700+a=3944-b=c-80=3000
Answer:
A = 3244
B = 864
C = 3080
Step-by-step explanation:
700 + a = 3944
-700 -700
a = 3244
3944 - b = c - 80 = 3000
c - 80 = 3000
+80 +80
c = 3080
3944 - b = c ---> 3944 - b = 3080
-3944 -3944
-b = -864 ---> [tex]\frac{-b}{-1} = \frac{-864}{-1}[/tex]
The solution to the system of equations is:
a= 2380,
b= 864
c= 3080
The given equations are:
1. [tex]\(700 + a = 3944 - b\)[/tex]
2. [tex]\(3944 - b = c - 80\)[/tex]
3. [tex]\(c - 80 = 3000\)[/tex]
From equation 3, we can solve for [tex]\(c\)[/tex]:
[tex]\[c - 80 = 3000\][/tex]
Adding 80 to both sides:
[tex]\[c = 3080\][/tex]
Now, substituting this value of [tex]\(c\)[/tex] into equation 2:
[tex]\[3944 - b = 3080\][/tex]
Solving for [tex]\(b\)[/tex] :
[tex]\[b = 3944 - 3080\]\\b = 864\][/tex]
Finally, substituting the values of [tex]\(b\)[/tex] and [tex]\(c\)[/tex] into equation 1:
[tex]\[700 + a = 3944 - 864\]\\700 + a = 3080\][/tex]
Solving for [tex]\(a\)[/tex]:
[tex]\[a = 3080 - 700\]\\a = 2380\][/tex]
So the solutions for the variables are [tex]\(a = 2380\), \(b = 864\), and \(c = 3080\)[/tex].
