As per the concept of probability, there are 7776 different lottery numbers are possible.
Probability:
Probability means the concept that is based on the possible chances of something to happen.
Given,
Lottery numbers in a particular state consist of 5 digits. Each lottery cube that is drawn/rolled has six sides, numbered 1-6.
Here we need to find how many different lottery numbers are possible.
Through the given question we know that,
The number of digits in a lottery ticket = 5
Side in cube = 6
So, in each time they will roll the dice 5 times to get one number.
So, the possible options of that event are,
For the first time we have 6 options
Second time we got 6 options
Third time also we got six option
Fourth time = 6 options
Fifth time = 6 options.
Therefore, it can be written as,
=> 6 x 6 x 6 x 6 x 6
=> 6⁵
=> 7776.
Therefore, there are 7776 different lottery numbers are possible.

What is coordinate system?A Cartesian coordinate system in some kind of a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates, which are the signed distances from two fixed perpendicular lines that are aligned to the point and are both measured in the same length.
According to the given data:point of the coordinates are as follows:
A(2, 1)
B(8, 6).
C(10, 1)
We know that the formula for finding for the distance is:
d=√((x2 – x1)² + (y2 – y1)²).
For Point AB:
X₁ = 2
Y₁ = 1
X₂ = 8
Y₂ = 6
putting the values onto formula we get:
d=√((x2 – x1)² + (y2 – y1)²).
d=√((8 – 2)² + (6 – 1)²).
d=√((6)² + (5)²).
d=√(36 + 25).
d=√(61).
AB =7.81
For Point BC:
X₁ = 8
Y₁ = 6
X₂ = 10
Y₂ = 1
putting the values onto formula we get:
d=√((x2 – x1)² + (y2 – y1)²).
d=√((10 – 8)² + (1 – 6)²).
d=√((2)² + (-5)²).
d=√(4 + 25).
d=√(29).
BC = 5.38
For Point CA:
X₁ = 10
Y₁ = 1
X₂ = 2
Y₂ = 1
putting the values onto formula we get:
d=√((x2 – x1)² + (y2 – y1)²).
d=√((2 – 10)² + (1 – 1)²).
d=√((-8)² + (0)²).
d=√(64 + 0).
CA = 8
The perimeter of the given figure is:
Sum of all the sides.
AB + BC + CA
7.81 + 5.38 + 8
21.19 cm
Now finding the area of the tringle we use Pythagoras formula:
H² = P² + B²
P² = H² - B²
P² = (7.81)² - (5.38)²
P = 9.4837
We know that the area of the triangle is: = 1/2(base * Hight).
= 1/2(5.38 * 9.48)

The coordinates of the point P lying between AB is found as (7, -2/5).
What is termed as the section formula?The Section formula is used to calculate the coordinates of a point that separates a line segment either internally or externally into a certain ratio. When a point separates a line segment in some ratio, we just use section formula to determine the coordinates of the that point.For the given question;
The two end coordinates are;
(x₁, y₁) = (8, 0)
(x₂, y₂) = (3, -2)
The ratio of the division is;
AP/PB = 1/4
OR
m:n = 1:4
The Formula for finding the coordinates of P for internally crossing is;
x = (mx₂ + nx₁)/(m + n)
y = (my₂ + ny₁)/(m + n)
Put the values;
x = (mx₂ + nx₁)/(m + n)
x = (1×3 + 4×8)/(1 + 4)
x = (3 + 32)/5
x = 7
Now for y coordinates.
y = (my₂ + ny₁)/(m + n)
y = (1×(-2) + 4×0)/(1 + 4)
y = -2/5
Thus, the coordinates of the point P lying between AB is found as (7, -2/5).

11 is the greatest number of bags that Jason can fill with equal number of raspberry and blackberry scones.
In this question we have been given Jason has 22 raspberry scones and 55 blackberry scones.
We need to find the maximum number of bags Jason can fill with equal number of raspberry scones and blackberry scones.
We will be using Greatest common factor (GCF) for knowing the number of bags.
22 = 2 × 11
and 55 = 5 × 11
So, the greatest common factor of 22 and 55 is 11
GCF(22, 55) = 11

(b) What percentage of the resulting mixture is copper?
a)There is 160 grams of copper are in the resulting mixture
b) There is 61.5% percentage of the resulting mixture is copper.
What are mathematics operations?
• An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value.
• The operation's arity is determined by the number of operands.
• Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations.
• A zero-arity operation, also known as a nullary operation, is a constant.
• The mixed product is an example of an arity 3 operation, also known as a ternary operation
From the question:
a) Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.
The number of grams of copper in the resulting mixture = 70 grams + 90 grams = 160 grams
b) 70 grams of an alloy that contains 12% copper = 70 × 12%
= 70 grams × 0.12
= 8.4 grams
The number of grams of copper in the resulting mixture = 160 grams
The percentage of the resulting mixture that is copper is
=( 8.4 grams + 90 grams of pure copper/160) × 100
= 98.4/160 × 100
= 61.5%

Given: m//n
Prove: m2 + m28 = 180
Interior Angle Theorem asserts that the alternate interior angles that result when two parallel lines are cut by a transversal are equivalent.
If m2 + m28 = 180 then we get ∠2 + ∠8 = 180°
What are the theorems for parallel lines?Lines that are parallel to one another on a plane do not intersect or meet at any point. They are always equidistant from one another and parallel. Non-intersecting lines are parallel lines.
Two lines are said to be parallel if a transversal and two matching angles it forms are congruent.
Verification of Parallel Lines
that which contradicts the alternate interior angles theorem.the opposite of the theorem relating comparable angles.the converse of the same-side interior angles hypothesis.alternative exterior angles theorem's opposite.When two lines are intersected by a transversal and the opposing interior angles line up, the intersected lines are said to be parallel. Two lines are said to be parallel if they are divided by a transversal such that their opposing exterior angles are equivalent.
Therefore,
Given line m is parallel to line m
Interior Angle Theorem asserts that the alternate interior angles that result when two parallel lines are cut by a transversal are equivalent.
Alternate Exterior Angles are congruent if a transversal cuts two parallel lines. When a transversal cuts two parallel lines, the resulting angles are congruent.
Therefore, ∠2 = ∠6
∠2 + ∠4 = 180° ( Sum of the angles on a straight line is 180°)
∠6 + ∠8 = 180° ( Sum of the angles on a straight line is 180°)
∵ ∠2 = ∠6
∴ ∠6 + ∠8 = 180° ⇒ ∠2 + ∠8 = 180°
∠2 + ∠8 = 180° , Hence Proved.

Which relation is a function?
let's recall the vertical line test, if a vertical line hits the graph or points twice, then is NOT a function. Check the picture below.
A very easy way to find out if a graph is a function is to use the vertical line test.
Look at each graph and mentally draw a vertical line that goes through each of its points.
If that line goes through more than one point (2, 3, 4...) then that graph is not a function.
That's because a function, is an equation for which each input (x value) has exactly one output (y value). There cannot be two points of the same x value, with two different y values.

A pancake stall sells sweet pancakes and savoury pancakes. The savoury pancakes can have three toppings (eggs, ham, tomato) which may be used in any combination. The sweet ones come with orange, lemon or strawberry jam with either ice cream or fresh cream. How many combinations does the stall sell?
The pancakes stall sells total 12 combinations of pancakes.
What is Combination?
Combinations are mathematical operations that count the number of potential permutations for a set of elements when the order of the selection is irrelevant.
According to the given data:
Savory pancakes can have 3 toppings in any combination.
Therefore, total number of savory pancake combinations = 3 x 2 x 1 = 6
For sweet pancakes jams can either have ice cream or fresh cream.
Therefore combinations with ice cream = 3
And combinations with fresh cream = 3
Hence total combinations for sweet pancakes = 3 + 3 = 6
Now, total pancakes combination = 6 + 6 = 12
So, the stall sells 12 combinations of pancakes.
