The sample space of rolling a six-faced dice is {1, 2, 3, 4, 5, 6}.
The sample space of an experiment is the set of all possible outcomes of the experiment. In the experiment of rolling a six-faced dice, the sample space is the set of all possible values that the dice can show when it is rolled.
Since a dice has six faces, each with a distinct number (1, 2, 3, 4, 5, or 6), the sample space of the experiment of rolling a six-faced dice is {1, 2, 3, 4, 5, 6}. This means that any time the dice is rolled, it can only show one of these six values.
It's important to note that the sample space is a finite set, as there are only a limited number of possible outcomes. In this case, the sample space contains only six elements, each representing one of the faces of the dice that can show up when it is rolled.

what is the area of the shaded portion in the figure? If, it is a square and the lines are parts of a circle and the side of the square is 10 unit. Give answers in terms of pi.
Answer:
Step-by-step explanation:
The shaded portion in the figure is a quarter-circle with a radius of half the side length of the square, or 10/2 = 5 units.
The area of a circle can be calculated using the formula:
A = πr^2
Where r is the radius and π is pi (approximately equal to 3.14).
So the area of a quarter-circle with a radius of 5 is:
A = (π * 5^2) / 4 = (π * 25) / 4 = 25π / 4
This is the area of the shaded portion in the figure.
Craig likes to collect vinyl records but decided to sell a few. Last year he had 120 records in his collection. Now he has 100 records. What is the percent change and is it an increase or a decrease?
Salut/Hello!
Answer: 16,(6)% and it's a decrease
Step-by-step explanation:
/ - fraction line
initial records = 120
after selling = 100
=> records sold = 120 - 100 = 20
We know that:
100% = 120/100 => 1% = 1.2/100
120 - 100 = 20
So we can find: 20 : 1.2 = 16,(6)%
Because 5% = 6 and 6 : 1.2 = 5%
So by knowing the amount of records sold and the percentage per record we divide them and find out the percentage of records sold.

During a volleyball lounge, a team scored 36 goals. If the team had played five matches less, its goal average would have been exactly four goals per game. How many matches had the team played?
Answer: 14
Step-by-step explanation:
Let's call the number of matches the team played "x".
We know that the team scored 36 goals in total, and if they had played five matches less, their goal average would have been exactly four goals per game. We can use this information to set up the following equation:
(36 goals) / (x - 5 matches) = 4 goals per match
To solve for x, we need to isolate x on one side of the equation. To do this, we can multiply both sides of the equation by (x - 5):
36 = 4(x - 5)
36 = 4x - 20
56 = 4x
Now we can divide both sides of the equation by 4:
x = 14
Therefore, the team played 14 matches in total.

18
33
The correct answer is option A. The boat should travel 12 kilometers in 3 hours.
Since the boat will travel a total distance of 20 kilometers during the 5-hour tour, and the speed is constant, we can calculate the average speed of the boat by dividing the total distance by the total time: 20 kilometers / 5 hours = 4 kilometers per hour.
To find the distance the boat should travel in 3 hours, we multiply the average speed by the time: 4 kilometers per hour * 3 hours = 12 kilometers.
In summary, the boat should travel 12 kilometers in 3 hours because the average speed is 4 kilometers per hour and the time is 3 hours.

Debemos tener la misma masa en ambos brazos del tubo, entonces veremos que la altura que alcanza la columna de aceite es 0.33m
¿Cuál es la altura que alcanza la columna del aceite?La altura de la columna de aceite será de tal forma que la masa en ambos brazos sea igual.
Recordar que la masa es el producto entre la densidad y el volumen, para el caso de cilindros, el volumen es el producto entre la altura H y el area circular A.
Para que las masas sean iguales debemos tener que:
A*(0.30 m)* (1 g/cm^3) = A*(H)*(0.9 g/cm^3)
Podemos remover A de ambos lados para obtener:
(0.30 m)* (1 g/cm^3) = (H)*(0.9 g/cm^3)
Resolviendo esto para H obtendremos:
H = (0.30 m)* (1 g/cm^3)/(0.9 g/cm^3)
H = 0.33m

find the average rate of change of the function over the given interval. p(θ)=θ3−5θ2 6θ; [1,2]
The average rate of change of the function p(θ) over the interval [1,2] is 0.
The average rate of change of a function over an interval is given by the slope of the secant line that connects the two points on the function at the endpoints of the interval.
For the function p(θ)=θ^3−5θ^2 + 6θ and the interval [1,2], the average rate of change can be calculated as:
(p(2) - p(1)) / (2 - 1) = ((2^3 - 5 × 2^2 + 6 × 2) - (1^3 - 5 × 1^2 + 6 × 1)) / (2 - 1) = ((8 - 20 + 12) - (1 - 5 + 6)) / (2 - 1) = (0) / (1) = 0.

how to create a vector that ranges from 0 to π and contains 32 evenly spaced elements.
The process of creating a vector that ranges from 0 to π and contains 32 evenly spaced elements is illustrated below.
A vector is a mathematical concept that is used to represent a set of numbers in an ordered manner.
To create a vector that ranges from 0 to π and contains 32 evenly spaced elements, you first need to determine the step size.
This is done by dividing the range (π - 0) by the number of elements (32) and subtracting 1. In this case, the step size is
=> (π - 0) / (32 - 1) = π / 31.
Next, you will create a variable to represent the starting value of the vector, which is 0.
Finally, you can use the append function to add the elements of the vector to the list or array.
To ensure that the vector contains 32 evenly spaced elements, you can check the length of the vector using the len() function, and you can also check the spacing of the elements by printing the values of the vector.

What is a triangle?With three sides and three vertices, triangles are a particular type of polygon in geometry. It has three straight sides and is a two-dimensional figure. As a 3-sided polygon, a triangle is included. Three triangle angles added together equal 180 degrees. In one plane, the triangle is contained. The triangle can be categorised into six different types based on its sides and angle measurements.
Triangles can be divided into 3 categories according to their sides, including:
Triangle with scalene dimensions: Each side has a different size.
Triangle with an isosceles shape, in which two of the sides have the same length and the third side is shorter.
All three of a triangle's sides have the same length, or equilateral triangle.
Now for given triangle ABC,
ad² +bd² =ab² by Pythagoras theorem
ab² =10² +30²
ab² =1000
ab=10√10
and
bc² =cd^2+bd² by Pythagoras theorem

3) What is the circumcenter?
4) What is the orthocenter?
Perpendicular bisectors of a triangle's sides meet at the circumcenter. It is situated at the equator of a triangle.
What is Circumcenter?The circumcenter is where the perpendicular bisectors of a triangle's sides meet. It is located in the middle of a triangle's perimeter. Draw the perpendicular bisectors of the sides and extend them to determine the circumcenter of any triangle. The circumcenter of the triangle will be determined by where the perpendiculars cross.
Here,
Given : (1, 10), (-5, 2), and (7, 2).
=> Perimeter of given triangle is:6
=> √(6)² + (8)² = √100 = 10
=>√(12)² = 12
=> √(6)² +(-8)² = 10
Perimeter = 10+ 12+ 10 = 32
The orthocenter is the location where the altitudes traced from a triangle's vertices intersect.
The place where the triangle's three elevations converge is known as the orthocenter. A line that goes through the triangle's vertices and is parallel to the other side is said to be an altitude. A triangle's orthocenter is the intersection of the perpendiculars that connect its vertices to its two sides.

Scatterplot provides a visual representation of the relationship between two variables and can be used to determine the strength and type of relationship between them.
The scatterplot is a useful tool for analyzing the relationship between two variables. In this scatterplot, each point represents a single data point (i.e. a grade for a student). The x-axis represents the discrete math course grade, and the y-axis represents the business calculus course grade.
From the scatterplot, it is possible to determine if there is a positive, negative, or no relationship between the two variables. A positive relationship means that as the value of x increases, the value of y also increases.
A negative relationship means that as the value of x increases, the value of y decreases. And no relationship means that there is no correlation between the two variables.
It is also possible to determine the strength of the relationship between the two variables by looking at the distribution of the points.
