Desmond kept track of his results for all 72 rolls. The table at right shows some of his results. Based on his partial results, how many times did he roll a 5 or a 6?
The number of times of rolling a 5 or a 6 in the fair die is 24
What is a reasonable prediction for the number of times of rolling a 5 or a 6?From the question, we have the following parameters that can be used in our computation:
Fair 6-sided die = 72 times
In a 6-sided die, we have
P(5 or 6) = 2/6
When evaluated, we have
P(5 or 6) = 1/3
So, when the die is rolled 72 times, we have

Suppose that someone is offering to sell you raffle tickets. there are blue, green, yellow, and red tickets available.
each ticket costs the same to purchase regardless of color. the person selling the tickets tells you that 369 blue tickets,
488 green tickets, 523 yellow tickets, and 331 red tickets have been sold. at the drawing, one ticket of each color will
be drawn, and four identical prizes will be awarded. which color ticket would you buy? explain your answer.
Buy yellow or green ticket for best chance of winning.
Which color ticket to buy?To determine which color ticket to buy, we need to calculate the probability of winning with each color.
First, we need to determine the total number of possible combinations of one ticket of each color. This can be calculated by multiplying the number of tickets of each color together:
Total number of possible combinations = 369 x 488 x 523 x 331 = 39,123,833,144
Next, we need to determine the probability of winning with each color. Since there are four identical prizes, the probability of winning with any one color is the same. We can calculate the probability of winning with a specific color by dividing the number of tickets of that color by the total number of possible combinations:
Probability of winning with blue ticket = 369 / 39,123,833,144 ≈ 0.00000943
Probability of winning with green ticket = 488 / 39,123,833,144 ≈ 0.00001248
Probability of winning with yellow ticket = 523 / 39,123,833,144 ≈ 0.00001337
Probability of winning with red ticket = 331 / 39,123,833,144 ≈ 0.00000846
From the calculations above, we can see that the highest probability of winning is with the yellow ticket, followed closely by the green ticket. Therefore, if we want to maximize our chances of winning one of the prizes, we should buy the yellow or green ticket.
It's important to note that the difference in probabilities between the yellow and green tickets is very small, so the decision of which color to choose ultimately depends on personal preference.

From the collected data, what
is the mean number of
rebounds Jamie had per
game?
From the collected data, what
is the median number of
rebounds Jamie had for her
final 10 games?
Step-by-step explanation:
1. To find the mean number of rebounds Jamie had per game, we need to add up all the rebounds she had and then divide by the total number of games played:
Mean = (8 + 12 + 8 + 11 + 15 + 6 + 9 + 8 + 10 + 13) / 10
Mean = 100 / 10
Mean = 10
Therefore, the mean number of rebounds Jamie had per game was 10.
2. To find the median number of rebounds Jamie had for her final 10 games, we need to first arrange the data in order from least to greatest:
6, 8, 8, 8, 9, 10, 11, 12, 13, 15
Since there are an even number of data points, the median will be the average of the two middle values, which are 9 and 10:
Median = (9 + 10) / 2
Median = 9.5
Therefore, the median number of rebounds Jamie had for her final 10 games was 9.5.

what’s is the distance between (-2,7) and (-5,9)
We can use the distance formula to find the distance between two points in a coordinate plane:
d = √[(x2 - x1)² + (y2 - y1)²]
where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them.
Using the given coordinates of the two points, we have:
x1 = -2, y1 = 7
x2 = -5, y2 = 9
Substituting these values into the distance formula, we get:
d = √[(-5 - (-2))² + (9 - 7)²]
d = √[(-3)² + 2²]
d = √(9 + 4)
d = √13
Therefore, the distance between the points (-2, 7) and (-5, 9) is approximately √13 units. We can also approximate this value as 3.61 units (rounded to two decimal places).

Instructors led an exercise class from a raised rectangular platform at the front of the room. The width of the platform is (x+4) meters long and the area of the rectangular platform is 3x^2+10x−8. Find the length of the platform
The length of the platform is given by the expression -2 + sqrt(3x^2 + 10x) meters.
Let's start by using the formula for the area of a rectangle, which is:
Area = length x width
We are given that the width of the platform is (x+4) meters, so we can write:
Area = length x (x+4)
We are also given that the area of the platform is 3x^2+10x−8, so we can set these two expressions equal to each other and solve for the length:
3x^2+10x−8 = length x (x+4)
Expanding the right side, we get:
3x^2+10x−8 = length x^2 + 4length
Subtracting 4length from both sides, we get:
3x^2+10x−8−4length = length x^2
Rearranging, we get a quadratic equation:
length x^2 + 4length − 3x^2 − 10x + 8 = 0
To solve for length, we can use the quadratic formula:
length = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 1, b = 4, and c = -3x^2 - 10x + 8. Plugging in these values, we get:
length = (-4 ± sqrt(4^2 - 4(1)(-3x^2 - 10x + 8))) / 2(1)
Simplifying under the square root:
length = (-4 ± sqrt(16 + 12x^2 + 40x - 32)) / 2
length = (-4 ± sqrt(12x^2 + 40x)) / 2
length = (-4 ± 2sqrt(3x^2 + 10x)) / 2
length = -2 ± sqrt(3x^2 + 10x)
Since the length must be positive, we take the positive square root:
length = -2 + sqrt(3x^2 + 10x)
Therefore, the length of the platform is given by the expression -2 + sqrt(3x^2 + 10x) meters.

The quantity of a substance can be modeled by the function R(t) that satisfies the differential equation dR/dt= -1/5(R – 20). One point on this function is R(2) = 35. Based on this model, use a linear approximation to the graph of Rat t = 2 to estimate the quantity of the substance at t 1.9. \
The estimated quantity of the substance at t = 1.9 is approximately 35.3 units.
To estimate the quantity of the substance at t = 1.9 using linear approximation, we can use the formula:
ΔR ≈ dR/dt * Δt
Given the point R(2) = 35 and the differential equation dR/dt = -1/5(R – 20), we can first find the value of dR/dt at t = 2.
dR/dt(2) = -1/5(R(2) – 20) = -1/5(35 – 20) = -1/5(15) = -3
Now, we can calculate Δt, which is the difference between the given t-value (2) and the desired t-value (1.9):
Δt = 1.9 - 2 = -0.1
Next, we can calculate ΔR using the linear approximation formula:
ΔR ≈ dR/dt * Δt ≈ -3 * (-0.1) = 0.3
Finally, we can estimate the quantity of the substance at t = 1.9 by adding ΔR to the given value of R(2):
R(1.9) ≈ R(2) + ΔR ≈ 35 + 0.3 = 35.3
Therefore, the estimated quantity of the substance at t = 1.9 is approximately 35.3 units.

A rectangular garden has an area of 100 square meters. The length of the garden is 10 meters more than the width. What is the perimeter of the garden?
Answer:
40 meters
Step-by-step explanation:
Let's assume the width of the garden is x meters, then the length of the garden would be (x+10) meters since we know that the length is 10 meters more than the width.
We also know that the area of the garden is 100 square meters, therefore:
Area = Length x Width
100 = (x+10) x x
Expanding the equation we get:
100 = x^2 + 10x
Rearranging the terms we have:
x^2 + 10x - 100 = 0
Solving for x using the quadratic formula, we get:
x = 5 or x = -20
Since the width cannot be negative, we discard the negative solution and conclude that the width of the garden is 5 meters. Therefore, the length of the garden is (5+10) = 15 meters.
The perimeter of the garden is the sum of the four sides, which is:
Perimeter = 2 x (Length + Width)
Perimeter = 2 x (15 + 5)
Perimeter = 2 x 20
Perimeter = 40 meters
Therefore, the perimeter of the garden is 40 meters.
Answer:
Let's start by using algebra to solve for the width of the garden:
- Let w be the width of the garden.
- Then the length of the garden is w + 10.
- The area of the garden is length x width, so we can write the equation: (w + 10)w = 100.
- Expanding the left side of the equation, we get: w^2 + 10w = 100.
- Rearranging the equation, we get: w^2 + 10w - 100 = 0.
- Factoring the left side of the equation, we get: (w + 20)(w - 10) = 0.
- Solving for w, we get: w = -20 or w = 10. Since the width cannot be negative, we have w = 10.
Now that we know the width of the garden is 10 meters, we can find the length by adding 10 meters:
- Length = width + 10 = 10 + 10 = 20 meters.
Finally, we can find the perimeter of the garden by adding up the lengths of all four sides:
- Perimeter = 2(length + width) = 2(20 + 10) = 2(30) = 60 meters.
Therefore, the perimeter of the garden is 60 meters.
For what values of a and b will this equation have infinitely many solutions?
5(x + 3) = a(x + 4) + 3x + b
Answer: To have infinitely many solutions, the equation must be true for all values of x. In other words, the left side and right side of the equation must be equivalent, meaning that the coefficients of x on both sides of the equation must be equal, and the constant terms on both sides must be equal.
We can simplify the given equation as follows:
5(x + 3) = a(x + 4) + 3x + b
5x + 15 = ax + 4a + 3x + b
Simplifying further, we get:
8x + 4a + b = 5x + 15
Rearranging terms, we get:
3x + 4a + b - 15 = 0
For this equation to have infinitely many solutions, the coefficients of x on both sides must be equal to zero, meaning that:
3 = 0
This is not possible, so the equation cannot have infinitely many solutions for any values of a and b.
Therefore, there are no values of a and b for which the given equation will have infinitely many solutions.

To find the height of the pile of books in terms of a and b, we need to multiply the number of books by the thickness of each book. Since there are (2a+b) books in the pile and the thickness of each book is 2cm, the height of the pile can be expressed as:
(2a+b) x 2cm
Expanding this expression, we get:
4a cm + 2b cm
Therefore, the height of the pile of books in terms of a and b is 4a cm + 2b cm. This means that for every additional 'a' book, the height of the pile will increase by 4cm and for every additional 'b' book, the height of the pile will increase by 2cm.
It's important to note that this formula assumes that all the books are the same size and have the same thickness. If there are any variations in size or thickness, the formula may not accurately represent the height of the pile. Additionally, it's important to ensure that all units of measurement are consistent (in this case, cm for both the thickness of the book and the height of the pile).

Your school newspaper has an editor-in-chief and an assistant editor-in-chief. The newspaper staff
has 5 students. How many different ways can students be chosen for these positions?
There are 20 different ways the students can be chosen for the positions of editor-in-chief and assistant editor-in-chief.
There are 5 students in the newspaper staff, and two positions to fill i.e. editor-in-chief and assistant editor-in-chief. We need to find the number of different ways the students can be chosen for these positions.
To solve this problem, we can use the formula for permutation
We know the formula for Permutation is
[tex]P(n,r)=\frac{n!}{(n-r)!}[/tex]
Here, n=5 and r=2
So, P(5,2) = 5!/(5-2)!
= 5!/3!
= 120/6
= 20
Therefore, there are 20 different ways the students can be chosen for the positions of editor-in-chief and assistant editor-in-chief.

How would the variation that exists between the distance that a man walks in one hour and the rate at which the man is walking be described? f inversely g directly h both inversely and directly j irregular
The relationship between these two variables can be described as inversely proportional.
The variation between the distance that a man walks in one hour and the rate at which the man is walking can be described as inversely proportional.
This means that as the rate at which the man is walking increases, the distance that he walks in one hour decreases. Similarly, as the rate at which he is walking decreases, the distance that he walks in one hour increases.
Therefore, the relationship between these two variables can be described as inversely proportional.
