A complete probability model provides a framework for calculating the likelihood of events within an experiment or a process. When we talk about a complete probability model, we are referring to a comprehensive description that includes all necessary components to understand and predict outcomes within a probability space.
Let's look at each option and determine which one correctly describes a complete probability model:
A. A list of all possible outcomes in the sample space and their probabilities.
- **This option is correct because a complete probability model does indeed require a list of all possible outcomes (the sample space) and the probability associated with each outcome.** Every outcome must be accounted for, and the sum of the probabilities of all individual outcomes must equal 1. This is because the sample space encompasses every possible outcome that could occur, and their associated probabilities reflect the likelihood of each of these outcomes.
B. The actual outcomes of a trial.
- This option is incorrect because the actual outcomes of a trial are observational results from a single execution of the probability experiment and do not represent a comprehensive model. A complete probability model is theoretical and does not depend on individual trial results, even though it can predict the distribution of those results over many trials.
C. The number of trials conducted.
- This option is incorrect. The number of trials refers to the experimental aspect of probability where an experiment or process is repeated multiple times. It does not provide a model of the entire probability space, only empirical data based on these repetitions.
D. The difference between the theoretical and experimental probabilities of all outcomes.
- This option is incorrect as it refers to the concept of variance between what is expected theoretically and what is observed in practice. While this can be a useful measure for understanding how closely an experiment follows its theoretical predictions, it is not a description of a complete probability model itself.
Given the options, the correct answer is:
A. A list of all possible outcomes in the sample space and their probabilities.
This is the definition of a complete probability model as it provides the necessary information to fully describe the probability of events within a given context.

how do i graph y = 2x - 1
Answer:
Step-by-step explanation:
Make a table that has (x) on the left and (y) on the right. There should be a slash between them. After that, you should place the numbers (1,2,3,4,5...) on the x column or on the left. Then times the x in y = 2x - 1 with the numbers on the left and that would give the numbers on the right. Once you are done with that, then pair the numbers from the left to the right. Then simply graph it.
But always remember, left is (x) and right is (y)
Jason and Shawn both begin riding their bikes from different points away from the ranger station. They both ride their bikes in the direction away from the station along the same trail.
Jason starts biking 1 mile away from the station. Jason rides at a constant speed of 20 miles per hour.
Shawn starts biking 2 miles away from the station. Shawn rides at the same constant speed as Jason.
Let y represent the total miles away from the station.
At how many hours, x, will it take Shawn to catch up with Jason?
Based on the information provided, complete each expression below and determine the number of solutions.
Answer:
No Solution
Step-by-step explanation:
Jason starts riding a bike 1 mile from the station.
Shawn starts biking 2 miles from the station.
For Jason to reach Shawn, he needs to go at a higher speed. However we know that they are going at the same constant speed. Then they will never meet.
To prove it we propose the following system of equations. Where x is the hours and y is the distance in miles.
For Jason we have:
[tex]y = 20x + 1[/tex]
For Shawn
[tex]y = 20x + 2[/tex].
We want to know when Jason and Shawn are at the same distance.
Then we write the following eqution and clear x:
[tex]20x + 1 = 20x + 2\\20x -20x + 1 = 2\\1 = 2[/tex]
Equality is not satisfied. Therefore, it has no solution.
I mean Jason and Shawn will never be the same distance

Please help, I'm currently confused on telling whether an absolute value equation has a solution or doesn't. For example, -5|x + 1| = 10 has no solution, and if you actually did it, the x would be -3, and 1. Meanwhile 2|x − 6| + 14 = 38 has a solution of x = −6, x = 18 and it has a solution??? I'm so confused.
PLLLLLL HELP!!!!!!!!!!!!!!!!!
Answer:
D
Step-by-step explanation:
We can use the "vertical line test" to determine whether a given graph represents a function or not.
If your vertical line intersects the graph in more than one place, the graph does NOT represent a function. Thus, D does not represent a function, as a line drawn vertically thru this graph intersects the graph multiple times.
Graph A: Note that if you draw a vertical line thru x = -2, your line will intersect the BLACK dot (-1 3/4, 0) and the EMPTY circle (-1 3/4, 3 1/4). This is OK; this graph represents a function.

On a piece of paper use a protractor to construct a triangle with angle measures of 40 and 60 what is the measure of the third angle?
Answer:
80°
Step-by-step explanation:
The angles of a triangle must add up to 180°.
40° + 60° + missing angle = 180°
100° + missing angle = 180°
subtract 100° from both sides
missing angle = 80°
2. Delia and Beto left for school at the same time.
Delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile. Beto lives 3 1/2 miles from school
and bikes at a pace of 3 minutes per mile. Who will get to
school first?
Answer:
Beto will get to the school first.
Step-by-step explanation:
We are given that Delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile.
So Delia takes [tex] \frac{3}{4} \times 16 = [/tex] 12 minutes to reach school.
While Beto lives 3 1/2 miles from school and bikes at a pace of 3 minutes per mile.
So Beto takes [tex] \frac{7}{2} \times 3 = [/tex] 10.5 minutes to reach school.
Therefore, Beto will get to the school first.
Can someone help me please? Thanks
Answer:
The volume of juice is 38.4 pi in^3
Step-by-step explanation:
First we need to find the volume of the cylinder
V = pi r^2 h
We need the radius
r = d/2 = 8/2 =4
V = pi * 4^2 *12
V = pi *16*12
V = 192 pi in^3
Remember we need the exact volume so we cannot approximate pi
Now it is 20% full of juice
Multiply the volume by 20 percent
192 pi * 20%
192 pi * .20
38.4 pi
The volume of juice is 38.4 pi in^3
Write the standard form of the equation of the circle with its center at (-5,0) and a radius of 8 what is the equation of the circle in standard form
Answer:
[tex]\large\boxed{(x+5)^2+y^2=64}[/tex]
Step-by-step explanation:
The standard form of an equation of a circle:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(h, k) - center
r - radius
We have the center (-5, 0) and the radius r = 8. Substitute:
[tex](x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64[/tex]
Evaluate h(d) =4/9d+6 2/3 for d=3
A. 8
B. 7
C.7 1/3
D. 2 2/3
For this case we have a function of the form [tex]y = h (d)[/tex]. Where:
[tex]h (d) = \frac {4} {9} d + 6 \frac {2} {3}[/tex]
Rewriting the mixed number as a fraction:
[tex]h (d) = \frac {4} {9} d + \frac {3 * 6 + 2} {3}\\h (d) = \frac {4} {9} d + \frac {20} {3}[/tex]
Substituting [tex]d = 3[/tex]:
[tex]h (3) = \frac {4} {9} (3) + \frac {20} {3}\\h (3) = \frac {4} {3} + \frac {20} {3}\\h (3) = \frac {24} {3}\\h (3) = 8[/tex]

What is the sum of the first 5 prime numbers
Final answer:
The sum of the first 5 prime numbers, which are 2, 3, 5, 7, and 11, is 28.
Explanation:
The sum of the first 5 prime numbers can be calculated by identifying those numbers and adding them together. The first 5 prime numbers are 2, 3, 5, 7, and 11. When we add these numbers, the sum is calculated as follows:
2 (the first prime number)
3 (the second prime number)
5 (the third prime number)
7 (the fourth prime number)
11 (the fifth prime number)
So, the sum would be 2 + 3 + 5 + 7 + 11 = 28.

find the height of a right rectangular prism with surface area 286 m^2, length 10 m, and width 8 m.
I need this ASAP
Answer: The height of the right rectangular prism is 3.5 meters.
Step-by-step explanation:
To find the height of the right rectangular prism, you need to use the formula of the surface area of a rectangular prism, where [tex]l[/tex] is the lenght, [tex]w[/tex] is the width and the height is [tex]h[/tex]:
[tex]SA=2wh+2lw+2lh[/tex]
Substitute [tex]SA=286[/tex], [tex]l=10[/tex] and [tex]w=8[/tex] into the formula and solve for the height of the right rectangular prism:
[tex]SA=2wh+2lw+2lh\\\\286=2(8)h+2(10)(8)+2(10)h\\\\286=16h+160+20h\\\\286=160+36h\\\\286-160=36h\\\\126=36h\\\\\frac{126}{36}=h\\\\h=3.5\ m[/tex]
Final answer:
Using the surface area formula for a right rectangular prism, the height is calculated to be 3.5 meters after setting up the equation with given surface area, length, and width.
Explanation:
To find the height of a right rectangular prism with a given surface area, length, and width, we can use the surface area formula for a prism: SA = 2lw + 2lh + 2wh, where SA is the surface area, l is the length, w is the width, and h is the height.
Given that the surface area is 286 m2, the length is 10 m, and the width is 8 m, we can set up the equation 286 = 2(10)(8) + 2(10)h + 2(8)h.
Simplify this to 286 = 160 + 20h + 16h, which further simplifies to 286 = 160 + 36h. Subtracting 160 from both sides, we get 126 = 36h. Dividing both sides by 36 gives us h = 3.5 m.
Therefore, the height of the prism is 3.5 meters.

Answer:
X= -8. (-8,8)
Step-by-step explanation:
If -4x-y=24 and y = 8 then it is -4x-8=24. +8 on both sides. -4x=32. divide -4 on both sides and you get that x = -8 because 32 divided by -4 is -8.
if im right sub to my you tube channel:
Josiah Rowell
and can i get brainliest
Answer:
(-8,8)
Step-by-step explanation:
-4x-y = 24
We know that y =8
Substitute that into the equation
-4x-8 = 24
Add 8 to each side
-4x-8+8 = 24+8
-4x = 32
Divide by -4
-4x/-4 = 32/-4
x = -8
a rectangle with a perimeter of 32 inches has whole-number side lengths. what is the difference between the greatest and the least areas of the rectangle?
Answer:
49
Step-by-step explanation:
Let x represent the length and y represent the width of the given rectangle. The perimeter of the rectangle will be:
Perimeter = 2(x + y)
32 = 2(x + y)
16= x + y
This means, the sum of length and width of the rectangle can be 16. Since only whole number side lengths are allowed, following are the possibilities:
Side Lengths: 15, 1 Area = 15Side Lengths: 14, 2 Area = 28Side Lengths: 13, 3 Area = 39Side Lengths: 12, 4 Area = 48Side Lengths: 11, 5 Area = 55Side Lengths: 10, 6 Area = 60Side Lengths: 9, 7 Area = 63Side Lengths: 8, 8 Area = 64Hence the largest possible value of Area is 64 and the least possible value is 15. The difference is 64 - 15 = 49
The perimeter of a square is 36 inches. Find the length of a diagonal. Round your answer to the nearest tenth.
Answer:
12.7
Step-by-step explanation:
The diagonal formula is x*sqrt(2) with x being one side length.
To find the side length divide the perimeter by 4.
That gives us 9.
Then, all you have to do is multiply that by the square root of 2 and then round.
To find the diagonal of a square with a perimeter of 36 inches, calculate the side length as 9 inches and apply the Pythagorean theorem, resulting in a diagonal length of approximately 12.7 inches.
Explanation:The perimeter of a square is given as 36 inches, so to find the length of one side, we divide the perimeter by 4, since a square has four equal sides. Therefore, each side of the square is 36 inches ÷ 4 = 9 inches. To determine the length of the diagonal, we can apply the Pythagorean theorem in the square. The square's diagonal splits it into two right triangles, each with legs equal to the side of the square. If we denote the length of the diagonal as d and one side as s, the formula d² = s² + s² applies.
With both sides being 9 inches, this becomes d² = 9² + 9², leading to d² = 81 + 81 = 162. Taking the square root to find d, we get d = √162, which is approximately 12.7 inches when rounded to the nearest tenth.
