The theoretical probability of getting a blue color is 1/4.

The experimental probability of landing a blue color is 35%.

Option A is the correct answer.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of times the blue color is recorded = 7

The total number of times each color is recorded = 20

Now,

Number of sections = 4

Number of blue sections = 1

So,

The theoretical probability of getting a blue color.

For a specific distance between two places, a grid scale factor is determined and referred to as a "line scale factor."

The ratio of the two equivalent side lengths of comparable figures is known as the scale factor, sometimes known as the linear scale factor. The shapes of similar figurines are the same, yet they come in various sizes. Geometrical problems are solved using the scale factor. To determine a figure's missing side lengths, apply the scale factor.

The ratio of one object's scale to that of a new object, which has its representation but is larger, is known as a scale factor (bigger or smaller). By multiplying each side by a certain number, say 2, we can increase the size of a rectangle with sides of 2 cm and 4 cm.

The value of 'n' in the equation 3n + 7 = 25 is equal to 6.

In the equation 3n + 7 = 25, 'n' is a variable representing an unknown value. To find the value of 'n', we need to isolate it on one side of the equation.

The first step is to remove the constant term 7 from the equation. This can be done by subtracting 7 from both sides of the equation, which gives:

3n = 18

The next step is to get 'n' alone on one side of the equation. This can be done by dividing both sides of the equation by 3, which gives:

n = 18/3

n = 6

C)The greatest number is 8.2 × 10-3. It is 2,000 times greater than the smallest number.

In scientific notation, a number is written as the product of a number between 1 and 10 and a power of 10. The power of 10 tells us how many places to move the decimal point to the right (if the exponent is positive) or to the left (if the exponent is negative).

In this case, 8.2 × 10-3 means 8.2 × (10^-3) = 0.0082, 5.2 × 10-6 means 5.2 × (10^-6) = 0.0000052 and 4.1 × 10-6 means 4.1 × (10^-6) = 0.0000041.

To compare the numbers, we can compare the coefficient or the number in front of the 10 power. We can see that 8.2 is greater than 5.2 and 4.1. To check how many times greater the smallest number is, we can use the following formula: (greatest number / smallest number) = (8.2 / 0.0000041) = 2,000

Therefore, the greatest number is 8.2 × 10-3 and it is 2,000 times greater than the smallest number.

Theoretically, Usain Bolt can complete a kilometer in 96.9 seconds, and he also moves at an average speed of 1.032 * 10 m/s.

speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.

Given that, At the 2008 Summer Olympics, Usain Bolt won the 100 m sprint with a time of 9.69 sec.

Thus,

The average speed of the athlete = 100/9.69

The average speed of the athlete = 10.319 m/sec.

If two numbers A and B are given, then the formula of the commutative property of numbers for addition is given as: A + B = B + A

The commutative property deals with the arithmetic operations of addition and multiplication. It means that changing the order or position of two numbers while adding or multiplying them does not change the end result.

For example, 4 + 5 gives 9, and 5 + 4 also gives 9. The order of two numbers being added does not affect the sum.

As a result, the commutative property is concerned with moving the numbers about. So, if altering the order of the operands has no effect on the result of the arithmetic operation, that arithmetic operation is commutative.

The ratio between of the two legs of a 30-60-90 triangle:

√3 : 2.

The correct option is D.

It is a triangle with constant angles of 30, 60, and 90. This triangle is always a right triangle, as one of the angles is 90 degrees. Thus, a right-angled triangle is formed by these angles. Additionally, the right angle is equal to the sum of two acute angles, which will have a 1: 2 or 2: 1 ratio.

Given:

A triangle is a 30-60-90 triangle.

So, the sides of a 30-60-90 triangle are always in the ratio of 1:√3: 2.

The side opposite is 60° is √3.

And The side opposite to 90° is 2.

a) The ratio of the number of white tiles to the number of blue tiles = 3:1

b) The ratio of the total cost of the white tiles to the total cost of the blue tiles = 3:2.

a)Since they are 48 white tiles and 16 blue tiles, the ratio of the number of white tiles to the number of blue tiles is the number of white tiles divided by the number of blue tiles. Therefore-

The ratio of white tiles to the blue tiles = number of white tiles/number of blue tiles = [tex]\frac{48}{16}[/tex] = 3

b)Total cost of the white tiles = number of white tiles × cost of each white tile = 48 tiles × £2 per tile = £96

Total cost of the blue tiles = number of blue tiles × cost of each blue tile = 16 tiles × £4 per tile = £64

To solve it using the "complete the square" method, write the equation as:

An arithmetic sequence can be defined in one of two ways. In an arithmetic sequence, "each term is obtained by adding a fixed number (positive or negative or zero) to its preceding term," or "each term is obtained where the differences between every two successive terms are the same." The arithmetic sequence that comes next is created by adding 4 to the term that comes before it.

Given that 89th term in an arithmetic sequence is -590

And 8th term is -23

-590 = a₁ + (89 - 1)d

-590 = a₁ + 88d

a₁ = -590 - 88d

and

-23 = a₁ + (8 - 1)d

-23 = a₁ + 7d

a₁ = -23 - 7d

Factor out a₁ in both equations

-590 - 88d =  -23 - 7d

-88d + 7d = 590 - 23

-81d = 567

d = -567.81

d = −7

As we have the d lets find fist term

a₁ = -23 - 7(-7)

a₁ = -23 + 49

a₁ = 26
