Determine the equation of the line of fit.
y = 5x + 60
y = 5x + 70
y = 10x + 60
y = 10x + 70
Answers
Let's look at the graph and pick two points, (2, 70) and (4, 80) and use slope formula, y2 - y1 / x2 - x1
80 - 70 / 4 - 2
10 / 2
5
The slope of this line is 5.
To find the y-intercept, we look where the line crosses through the y-axis or the vertical line.
The y-intercept is (0, 60) or 60
If we plug these numbers into slope-intercept form, we get y = 5x + 60
Your answer is y = 5x + 60

A bag consists of 5 marbles. There is 1 yellow, 1 red marble, 1 clear marble, 1 green marble, and 1 blue marble. Which table shows the sample space for choosing 2 marbles from the bag with replacement? Answer by looking at the images below!
Answers
Answer: The answer is D
Step-by-step explanation: We know that two marbles are being picked out of the bag. The first answer only shows one marble for each possibility so that is wrong because you're picking out two. The second one only has red paired with all of them. The possibilities cannot only have red in all of them so the second answer is wrong also. The third answer has some that only have one marble as the possibilities which cannot be possible because you're picking out two marbles with replacement which means you'll be able to get the same one again. The last one (D), shows all of the marbles being paired which each other. It also has 25 possibilities which makes sense because if there are 5 marbles, some possibilities will be repeated but in reverse, so you will times 5 by 5 to get 25. So the answer D is correct because it shows the right amount of possibilities and all of the marbles are paired correctly.
Have a good day :)
The Sample space for choosing marbles from the bag with replacement can be represented by a table.
The sample space for choosing 2 marbles from the bag with replacement can be represented by a table. Each row in the table represents one possible outcome, and each column represents the color of one marble. In this case, there are 5 colors to choose from: yellow, red, clear, green, and blue. Therefore, the table that shows the sample space for choosing 2 marbles with replacement would have 5 rows and 2 columns.

Leah is filling a cube-shaped box with packing material and gift items. Each edge length of the box is 20 inches. What is the greatest possible volume of all the presents and packing material inside the cube?
(Answer needed by 11:30pm-12:30pm)
Answers
To find the greatest possible volume of all the presents and packing material inside the cube, we need to fill the entire volume of the box.
Assuming that the packing material takes up some space, let's say half of the total volume or 4,000 cubic inches, the remaining 4,000 cubic inches would be the maximum possible volume for the gift items.
Therefore, the greatest possible volume of all the presents and packing material inside the cube is 4,000 cubic inches.

Your A value (-1) multiplies by everything inside of the parentheses.
-x+5=0
You move your constant (5) to the right side of the equation and flip the sign from a positive 5 to a negative 5.
-x=5 (5 + 0 just equals 5)
To get rid of the negative sign on the X, divide both sides of the equation by -x.
The answer would be:
x=5
You can repeat this process for other similar equations.
To turn equations into distributive form, follow these steps:
I see you gave me an equation with 5x + 11x. Remember, we are trying to get an A value and parenthesis. To do this, we need to find the GCF (Greatest common factor). Ex: If you were putting 5+10 in distributive form, the GCF would be 5, because five is the greatest common factor between 5 and 10, meaning it's the greatest possible number that goes into 5 (1 time) and 10 (2 times).
Although, there is no GCF in 5x+11x, but there are two common X values, so this may be put into distributive property such as:
X(5+11)
And if there's one variable like 9n+36, than it would be shaped like:
9(n+4)
For word problem 12 you have provided, they give you the base amount of cost when you purchase the ad is (84$) and the cost every day to run it is (28$). The max amount of money we can spend is 700$. With an initial cost of 84$, we can deduct 84$ from the max of 700$, which would leave us with 616$. We can than divide 616$ by 28$ to see how many days we can keep the ad running, which equals 22. So the max amount of days that the ad can be up is 22 days.
For 13, 1 basket is 12 inches tall, and 13.5 inches tall when another one is stacked inside of it. All we have to do here is subtract 12 from 13.5, which gives us 1.5. That means that every basket stacked adds another 1.5 inches. So if you stacked 5 baskets inside of one, it would be 1.5 x 5 + 12.
In 7 for the unit rates, it's just saying that 0.8 of a centimeter grew in four sevenths of a week. It wants to know how many centimeters a week, which would be around 1.4 centimeter per week because 4/5 divided by 4/7 = 7/4 which equals 1.4.
Where you rewrite the expressions to find the least amount of terms, literally all you are doing is combining like terms. on 10 D, you would first distribute 5 and than solve for any like terms (also the parentheses between both equations don't matter because of the sign in between them so you can just remove them). It should be self explanatory to combine like terms so on (like terms includes constants).

Jaden made a rectangular sign that is 1.4 meters long and 1.2 meters wide to post on the wall of his store. How many square meters of wall does the sign cover? The answer is 1.68, but to solve the problem, you need to find 1.4 x 1.2(which it is 1.68). Estimate the area of wall that the sign will cover. Explain your thinking please.
Answers
First, we can round the dimensions of the sign to the nearest whole number to make the multiplication easier. Rounding 1.4 to 1 and 1.2 to 1, we can estimate that the sign covers approximately 1 square meter of wall.
This estimation assumes that the sign is placed directly on the wall with no gaps or overlaps. In reality, the actual area of wall covered by the sign may be slightly larger or smaller depending on the installation method and any spacing between the sign and the wall.
It's important to note that while estimation can be useful for getting a rough idea of the answer, it's not always accurate and should not be relied upon for precise calculations. In this case, using the actual dimensions of the sign to find the area of the wall covered (1.4 x 1.2 = 1.68 square meters) gives a more accurate result.

y = 9/7 as input
x = -8/7 = -1 1/7
The solution to the system of linear equations is the point (8/7, -9/7). Graphically, this point represents the intersection of the two lines.
Explanation:To find the solution to the system of linear equations, we need to find the point where the two equations intersect. To do this, we can set the equations equal to each other and solve for x. -1/4x + 1 = -2x - 1. Simplifying the equation, we get 7/4x = 2. By multiplying both sides by 4/7, we find that x = 8/7. Plugging this value back into either equation, we find that y = -9/7. Therefore, the solution to the system of linear equations is the point (8/7, -9/7).
Graphically, the solution to the system of linear equations is represented by the point where the two lines intersect. The graph of y = -1/4x + 1 is a line with a slope of -1/4 and a y-intercept of 1, while the graph of y = -2x - 1 is a line with a slope of -2 and a y-intercept of -1. By plotting these lines on a graph, we can identify the point of intersection and determine the solution.

Here, we have,
The scatter plot shows a series of points in (input, output) format, in which the input is the time studying in minutes and the output is the grade.
As the increasing graph shows, the more a person studies, the better the grade, hence there is a positive relationship among the variables.
The increase is slow initially while it has a higher rate for a higher number of minutes, hence the association is also nonlinear.
As the X value increases, so does the Y value which means the positive association.
Also, it is in a straight line, which means it is a linear association.

What is 0.65 expressed as a fraction in simplest form?
What is 2.¯5 expressed as a fraction in simplest form?
What is 1.0¯24 expressed as a fraction in simplest form?
Answer:
Part A)
Part B)
Part C)
Answers
Answer:
Step 1: Write down the decimal as a fraction with the decimal number as the numerator and 1 as the denominator.
Step 2: Multiply both the numerator and denominator by 10^n, where n is the number of digits after the decimal point.
Step 3: Simplify the resulting fraction.
Using these steps, we can convert the given decimal numbers to fractions:
0.65
Step 1: 0.65 = 65/100
Step 2: Multiply numerator and denominator by 10 to get rid of the decimal point: 65/100 = 650/1000
Step 3: Simplify by dividing numerator and denominator by their greatest common factor of 50: 650/1000 = 13/20
Therefore, 0.65 expressed as a fraction in simplest form is 13/20.
2.¯5
To handle repeating decimal numbers, we can use the following method:
Step 1: Let x be the repeating decimal number.
Step 2: Multiply both sides of x by 10^n, where n is the number of digits in the repeating part of the decimal number.
Step 3: Subtract the original number from the number obtained in step 2 to eliminate the repeating part.
Step 4: Solve for x by dividing both sides of the equation obtained in step 3 by an appropriate factor.
Step 1: Let x = 2.¯5
Step 2: Multiply both sides by 10: 10x = 25.¯5
Step 3: Subtract the original equation from step 1: 10x - x = 25.¯5 - 2.¯5
Simplifying: 9x = 23
Step 4: Solve for x by dividing both sides by 9: x = 23/9
Therefore, 2.¯5 expressed as a fraction in simplest form is 23/9.
1.0¯24
Step 1: Let x = 1.0¯24
Step 2: Multiply both sides by 10^2 to eliminate the repeating part: 100x = 124.¯24
Step 3: Subtract the original equation from step 1: 100x - x = 124.¯24 - 1.0¯24
Simplifying: 99x = 123
Step 4: Solve for x by dividing both sides by 99: x = 123/99
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 3: 123/99 = 41/33.
Therefore, 1.0¯24 expressed as a fraction in simplest form is 41/33.
Step-by-step explanation:
0.65 expressed as a fraction in simplest form is 13/20.
2.5 expressed as a fraction in simplest form is 5/2.
1.024 expressed as a fraction in simplest form is 256/250.
What is the simplified form of the expressions in fraction?0.65 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 0.65 becomes 0.65/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 100 will do the trick, so we get (0.65 × 100)/(1 × 100) = 65/100.
Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 65 and 100 is 5, so dividing both by 5 yields 13/20.
2.5 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 2.5 becomes 2.5/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 10 will do the trick, so we get (2.5 × 10)/(1 × 10) = 25/10.
Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 25 and 10 is 5, so dividing both by 5 yields 5/2.
1.024 expressed as a fraction in simplest form:
Write the decimal as a fraction by placing it over 1. In this case, 1.024 becomes 1.024/1.
Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.
In this case, multiplying by 1000 will do the trick, so we get (1.024 × 1000)/(1 × 1000) = 1024/1000.
Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).
The GCD of 1024 and 1000 is 8, so dividing both by 8 yields 128/125.

On the other hand (conversely), the box plot (box-and-whisker plot) for Desert Landing is symmetrical (vertical line dividing the box into two equal halves), which simply means that both whiskers on either sides of the box plot (box-and-whisker plot) are relatively equal and symmetric.

I have provided an example of this explanation in visual terms, based on the image you provided. I tried to draw it in 3D, but I'm just not a really great artist, so I hope you can make out what I was trying to depict ;)
Hope I helped!
If you have any further questions, please comment on this answer and I'll try to respond as soon as I can!
