An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Joseph points = 2x - 6

Thomas points = 2x - 6 + 4 = 2x - 2

Eric points = 2 ( 2x - 6 + 2x - 2 )

Now,

The points Eric have is.

= 2 (4x - 8)

= 8x - 16

Therefore , the we need to pick n + 2 numbers  to be sure of random selection is an odd number.

In statistic, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. This procedure involves choosing a sample at random.

Here,

You must choose n + 2 numbers at random in order to guarantee that you will get at least one odd number.

Since n is a positive integer, the following values of n are possible:

{1, 2, 3, 4, ...}

Let's assume n = 1.

Now, in order to guarantee that you choose at least one odd integer from 0 to 2n = 2*1 = 2, how many must you choose (at random)?

There are three numbers from 0 to 2:

0, 1, 2

If you choose these at random, selecting all three digits will guarantee that you receive an odd number.

From 0 to 2*n, there are the following options if n = 2.

0, 1, 2, 3, 4

Five choices.

If you wish to choose at least one odd number for certainty after picking 3 even numbers, you must choose 4 numbers.

From 0 through 2*n, if n = 3, we get:

0, 1, 2, 3, 4, 5, 6

Since 4 of these are even, you must choose 5 of them to guarantee an odd number.

The amount of even numbers is always n + 1, therefore given a random integer n, we will have n + 1 even numbers from 0 to 2n. Therefore, if we want to be certain that we are selecting an odd number at random, we must choose n + 2 numbers.

Answer: -3x³ - 6x²  + 8x

Step-by-step explanation:

      In standard form, we order the terms in a polynomial with the highest degree on the left down to the lowest degree on the right. Make sure to keep the positive or negative "attached" to the mathematical term you are moving.

    Given;

8x - 6x² - 3x³

    3 > 2 > 1, so we will reorder:

-3x³ - 6x²  + 8x

-3x^3-6x^2+8x is the standard form of polynomial 8x-6x^2-3x^3.

Often, we arrange the terms in a polynomial in standard form in which the term with the highest degree is first and is followed by the other terms in order of decreasing powers.

The first term of a polynomial in this form is called the leading term, and the coefficient in this term is called the leading coefficient.

Using trigonometric ratio, the length of BE is 10 units, the value of sin B is 0.64 and cos B is 0.64 respectively

This is the ratio between the angles and sides of a right-angle triangle. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

In this problem, we have that

1)

Using tangent of B

tan B = opposite / adjacent

tan B = NE / BE

3/4 = 7.5 / BE

BE = 7.5 / 0.75

BE = 10

2)

To find sin B, we need to calculate the hypothenuse of the triangle which we will use Pythagoras's theorem

NB² = BE² + NE²

NB² = 10² + 7.5²

NB = 12.5

sin B = NE / NB

sin B = 7.5 / 12.5

B = sin⁻¹ (7.5 / 12.5)

B = 0.64

cos B = BE / NB

cos B = 10 / 12.5

- 6x + 15 < 10 - 5x , are correct representations of the inequality .

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. [1] The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:

The symbol a b indicates that an is smaller than b.

When a > b is used, it indicates that an is bigger than b.

A is not equivalent to b in any scenario. Since an is strictly less than or strictly greater than b, these relationships are known as stringent inequalities[1]. Equivalence is not considered.

There are two forms of inequality relations that are not strict, in contrast to strict inequalities:

The indication of an or b denotes that.

According to our question-

The difference is 5 (-3(2x - 5)). (2 - x)

First, make each side simpler.

∵ -3(2x - 5) = -3(2x) + -3(-5) (-5)

Recall that (+)=(-)

∴ -3(2x - 5) = - 6x + 15

∵ 5(2 - x) = 5(2) + 5(-x) (-x)

Recall that (+)(-) = (-)

∴ 5(2 - x) = 10 - 5x

∴ - 6x + 15 < 10 - 5x

Take 15 away from both sides.

∴ - 6x < -5 - 5x

5 times on both sides

∴ - x < - 5

Because the coefficient of x is negative, you must change the inequality's sign when you divide both sides by it.

The x coefficient is -1.

∴ Add -1 to both sides.

∴ x > 5

Answer:

x = 17

Step-by-step explanation:

x + 6 + 7x + 4 + 2x = 180  Combine like terms

10x + 10 = 180  Subtract 10 from both sides

10x = 170  Divide both sides by 10

x = 17

x = 17

1. Add the numbers

x + 6 + 7x + 4 + 2x = 180

x + 10 + 7x + 2x = 180

2. Combine like terms

x + 10 + 7x + 2x = 180

10x + 10 = 180

3. Subtract 10 from both sides

10x + 10 = 180

10x + 10 - 10 = 180 - 10

4. Simplify

Subtract the numbers:

10x + 10 - 10 = 180 - 10

10x = 180 - 10

Subtract the numbers:

10x = 180 - 10

10x = 170

5. Divide both sides by the same factor

10x = 170

[tex]\frac{10x}{10}[/tex] = [tex]\frac{170}{10}[/tex]

6. Simplify

Cancel terms that are in both the numerator and denominator:

[tex]\frac{10x}{10}[/tex] = [tex]\frac{170}{10}[/tex]

x = [tex]\frac{170}{10}[/tex]
