The classical probability of the given event is 1/4 or 0.25 or 25%.
The classical property of an event is the ratio of the total number of outcomes favorable to the event to the total number of outcomes in the experiment.
If we suppose an event A.
The total number of favorable outcomes to event A to be n.
The total number of possible outcomes in the experiment to be S.
Then, the classical probability of event A is given as:
P(A) = n/S.
In the question, we are informed that in a random experiment there are 8 possible outcomes, and two of them correspond to a favorable event.
We are asked to find the classical probability of the event.
As we know, the classical probability of an event is the ratio of the number of favorable outcomes to the event to the total number of possible outcomes in the experiment.
Thus, the classical probability = 2/8 = 1/4 or 0.25 or 25%.
Thus, the classical probability of the given event is 1/4 or 0.25 or 25%.

For the following exercises, solve the equations below and express the answer using set notation.
14. 2| 4 − x | = 7
Answer: 1/2, 15/2
Step-by-step explanation:
to solve this absolute value equation, all you need to do is divide the 2 over to the other side of the equation, giving:
|4-x|=7/2
and then you can remove the absolute value symbols and make 2 equations:
4-x=7/2
4-x=-7/2
solve these and you're done!
If 7 litres of petrol will last 23 minutes in Dave's car, then how long will 25 litres last? Give your answer to the closest minute.
Answer:
25 liters will last 82 minutes.
Step-by-step explanation:
All you have to do is divide 23 by 7 to get the minutes per liter.
This will get 3.285714285714286.
Next you multiply 3.285714285714286 by 25 and you get 82.14285714285714.
But since we need to round the answer by the closest minute the answer would be 82 minutes.

Answer:
[tex]y=\frac{-2}{3} x-15[/tex]
Step-by-step explanation:
First draw a line. I will put it in an attachment so you can see the line.
Now choose to points on the line to use the slope formula.
(0,15) and (3,13).
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Plug in the information needed using the two points chosen.
[tex]\frac{13-15}{3-0}=\frac{-2}{3}[/tex]
The slope is [tex]\frac{-2}{3}[/tex].
Now use point-slope formula.
Point-slope formula: y-y1=m(x-x1)
y-15=[tex]\frac{-2}{3}[/tex](x-0)
y-15=[tex]\frac{-2}{3}[/tex]x-0
Subtract 15 from both sides.
y=[tex]\frac{-2}{3}[/tex]x-15

Hello !
Answer:
Step-by-step explanation:
Pythagorean Theorem : a² + b² = c² ⇔ b² = c² - a²
Here, we have a = 4 and c = 6 so :
b² = 6² - 4²
⇔ b² = 36 - 16
⇔b² = 20
⇔ b = √20 (and not b= -√20 because b ≥ 0)
Answer:
b = [tex]\sqrt{20}[/tex]
Step-by-step explanation:
Using the Pythagorean Theorem:
6² = 4² + b²
⇒ b² = 6² - 4²
⇒ b = [tex]\sqrt{6^2 - 4^2}[/tex]
⇒ b = [tex]\sqrt{36 - 16}[/tex]
⇒ b = [tex]\sqrt{20}[/tex]

How many degrees is angle X?
How many degrees is arc ZY?
How many degrees is arc XY?
(Picture is below)
Answer:
X = 70°arc ZY = 140°arc XY = 82°Step-by-step explanation:
The angle sum theorem helps you compute the angle inside the triangle. The inscribed angle theorem helps you compute the arc measures outside the triangle.
TheoremsThe Angle Sum theorem tells you the sum of angles in a triangle is 180°. That lets you write the equation ...
X +Y +Z = 180°
X +69° +41° = 180°
The Inscribed Angle theorem tells you an inscribed angle has half the measure of the central angle subtending the same arc. The arc and the central angle have the same measure: twice that of the inscribed angle.
arc ZY = 2×∠X
arc XY = 2×∠Z
SolutionsUsing the equations we wrote describing the relationships of the unknowns to the known information, we find ...
X = 180° -110° = 70°
arc ZY = 2×70° = 140°
arc XY = 2×41° = 82°
Answer:Angle x=70°
Step-by-step explanation:interior angles add up to 180° so we add 41° and 69°. After addition,you minus from 180° and you get 70°

Using the mid-point concept, the set of points that has midpoint B(-41,23) is: G(10,10) and H(-92,36).
What is the mid-point concept?The mid-point between two points is the halfway point between them, and is found using the mean of the coordinates.
In this problem, we have that:
The mid-point is B(-41,23).The other points are G(10,10) and H(x,y).Hence the coordinates of H are found as follows:

The figure shows a circle circumscribed around a triangle.
Triangle U T V is inscribed within a circle. A point is at the center of the triangle. Lines are drawn from the points of the triangle to the point in the middle. Lines are drawn from the point in the middle to the sides of the triangle to form right angles.
What is constructed first when creating the circle?
perpendicular segments to the vertices of the triangle
perpendicular bisectors of the sides of the triangle
angle bisectors of each angle of the triangle
the incenter of the triangle
Option B is right perpendicular bisectors of the sides of the triangle
What circumcircle?If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.
One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.
When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.
When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C
In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC
Therefore Option B is right perpendicular bisectors of the sides of the triangle.

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse

tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of ∠BAC = 30°
The adjacent side of the triangle AC = √3 units
The hypotenuse of the triangle AB = 2 units
