Final answer:

The distance between – 14 and – 5 on a number line is 9 units, calculated by finding the absolute value of the difference between the two numbers.

Explanation:

The distance between two points on a number line is the absolute value of the difference between those two numbers. To find the distance between – 14 and – 5, subtract the smaller number (– 14) from the larger number (– 5) and then take the absolute value:

Distance = |(– 5) – (– 14)|

Distance = |9|

Distance = 9

Therefore, the distance on the number line between – 14 and – 5 is 9 units.

Step-by-step explanation:

The n th term of a geometric progression is

• [tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

given a₄ = 24, then

a₁[tex]r^{3}[/tex] = 24 → (1)

Given a₈ = [tex]\frac{8}{27}[/tex], then

a₁[tex]r^{7}[/tex] = [tex]\frac{8}{27}[/tex] → (2)

Divide (2) by (1)

[tex]r^{4}[/tex] = [tex]\frac{\frac{8}{27} }{24}[/tex] = [tex]\frac{1}{81}[/tex]

Hence r = [tex]\sqrt[4]{\frac{1}{81} }[/tex] = [tex]\frac{1}{3}[/tex]

Substitute this value into (1)

a₁ × ([tex]\frac{1}{3}[/tex] )³ = 24

a₁ × [tex]\frac{1}{27}[/tex] = 24, hence

a₁ = 24 × 27 = 648

Answer:

[tex]P (2) =\frac{1}{7}[/tex]  Theoretical probability

Step-by-step explanation:

The theoretical probability is defined as:

[tex]P = \frac{number\ of\ desired\ results}{number\ of\ possible\ results}[/tex]

In this case we look for the probability of taking a 2 out of the bag. As there is only one paper with the number 2 in the bag then:

number of desired results = 1

The amount of paper in the bag is equal to 7, so:

number of possible results = 7

Thus:

[tex]P (2) =\frac{1}{7}[/tex]

This is a theoretical probability, since we do not need to perform the experiment to calculate the probability.

To calculate the experimental probability we must perform the following experiment:

Take a paper out of the bag, record the number obtained and then return the paper to the bag.

Now repeat this experiment n times. (Perform n trials)

So:

[tex]P (2) = \frac{number\ of\ times\ you\ obtained\ the\ number\ 2}{number\ of\ trials\ performed}[/tex]

To calculate a theoretical probability you always need to perform an experiment with n trials.

Answer:

X= -7    

I LOVE LOVE LOVE LOVE EQUATIONS.

Step-by-step explanation:

ALRIGHT!

1. 6*(-x)= -6x

2. 6*(-3)= -18

3. Now right in normal 24= -6x-18

4. Now keep the variables on one side and the numbers on the other and simplify it. And when keeping the variables on one side and the numbers on the other what ever you switch you must change it's expression. So if it's + you make it -  and if it - you make it +. so 6x=-18-24= 6x=-42

5. Now simplify it. as a fraction. 6x = -42 = divide 6 on both sides now X= -7                                                      6       6

Final factor is (x-9)(x+4)

Step-by-step explanation:

Given expression is [tex]x^2- 5x- 36[/tex].

Now we need to factor that expression

[tex]x^2- 5x- 36[/tex]

Find two numbers whose product is -36 and sum is -5.

Two such numbers oare -9 and +4. So we get:

[tex]=x^2- 9x+4x- 36[/tex]

[tex]=x(x-9)+4(x-9)[/tex]

[tex]=(x-9)(x+4)[/tex]

Hence final factor is (x-9)(x+4)

Answer:

(x-9) (x+4)

Step-by-step explanation:

x^2- 5x- 36

What two numbers multiply to -36 and add to -5

-9*4 = -36

-9+4 = -5

(x-9) (x+4)

Answer:

Both sides are equal, true for all 'b'

Step-by-step explanation:

Add similar elements: b + 0.17b = 1.17b

1.17b = 1.17b

Multiply both sides by 100

1.17b * 100 = 1.17b * 100

Refine

117b = 177b

Subtract 117b from both sides

117b - 117b = 117b - 117b

Refine

0 = 0

Both sides are equal, true for all 'b'

Answer:

You are most likely a right triangle.

Step-by-step explanation: A polygon with 5 sides is the pentagon. A square has 4 angles, so with this, I can already tell that it is a triangle if it has 3 angles, (one less than a square). Then it says that it has 1 right angle. This would make the triangle a right. I hope this helps.

Final answer:

The polygon described has 'n - 2' sides, 3 angles with one being a right angle, and the other two totaling 90 degrees.

Explanation:

The polygon described in the question has 2 fewer sides than a regular polygon. Let's call the number of sides of the polygon 'n'. So, the polygon has 'n - 2' sides.

The polygon has 1 less angle than a square, which has 4 angles. So, the polygon has 4 - 1 = 3 angles.

The polygon described in the question has 1 right angle. A right angle measures 90 degrees. Since the polygon has 3 angles, and one of them is a right angle, the other two angles must add up to 180 - 90 = 90 degrees.

Putting it all together, the polygon described in the question has 'n - 2' sides, 3 angles with one of them being a right angle, and the other two angles totaling 90 degrees.

Answer:

A. Volley Ball game: 0.20

B. Rugby 7s game: 90%

Step-by-step explanation:

A. Volley Ball game: 12 ≤ x < 21

To calculate the probability, the first step is to evaluate the number of people meeting the requirement and then the number of the total population.

In this case, let's first sum up the total population, meaning the total audience at the Volley Ball game.  If we sum up all attendance numbers for the Volley Ball game (first column), we get 700 + 1,000 + 3,050 + 250 = 5,000 people.

Now, let's find out how many people we have in that attendance being 12 or older but less than 21.  That's the second line of the table, so 1,000.

That means that the probability the Fan Cam gets one of those 12 ≤ x < 21 fans is 1,000 / 5,000, so 1/5, which is equal to 20% or 0.20

B. Rugby 7s game: x > 12

As before, to calculate the probability, the first step is to evaluate the number of people meeting the requirement and then the number of the total population.

The total population is the total attendance of the game, so 500 + 1,000 + 2,500 + 1,000 = 5,000 people in the stadium.

How many of them are NOT less than 12 years of age?  We have to sum up the last 3 rows of the table: 1,000 + 2,500 + 1,000 = 4,500 people 12 or older.

So, what's the possibility one of those 12 or older will be spotted by the Fans Cam?  4500 out of 5,000 = 9/10, or 90%.

x = 3 is a solution for the equation x - 2 = 1. The solution for 7.5 - x = 2.8 is x = 4.7. Both solutions were verified by substituting back into the original equations.

Let's first determine for which equations x = 3 is a solution:

x + 7 = 4

Substitute x = 3: 3 + 7 = 10, which is not equal to 4. Hence, x = 3 is not a solution to this equation.

x - 2 = 1

Substitute x = 3: 3 - 2 = 1, which is correct. Therefore, x = 3 is a solution to this equation.

5 + x = 9

Substitute x = 3: 5 + 3 = 8, which is not equal to 9. Thus, x = 3 is not a solution to this equation.

8 - x = 11

Substitute x = 3: 8 - 3 = 5, which is not equal to 11. Therefore, x = 3 is not a solution to this equation.

The correct option is- b

Now, we solve the equation 7.5 - x = 2.8:

1. Start by isolating x:

7.5 - x = 2.8

2. Subtract 7.5 from both sides of the equation:

-x = 2.8 - 7.5

-x = -4.7

3. Multiply both sides by -1 to solve for x:

x = 4.7

The correct option is- a

Hence, the solution to the equation is x = 4.7.

Therefore x = 3 is a solution for the equation x - 2 = 1. The solution for 7.5 - x = 2.8 is x = 4.7.

Final answer:

The true statement about the greatest integer function is that it is a piecewise function. The common difference of the given sequence is 3.

Explanation:

Let's break down each part of the question to provide a clear and accurate response.

Part 1: Greatest Integer Function

The statement that is true about the greatest integer function is B. The greatest integer function is classified as a piecewise function. The greatest integer function, denoted as [x], returns the greatest integer less than or equal to x. This function is indeed piecewise because it is defined in multiple pieces - for each interval of real numbers between integers, it takes a constant value equal to the lower endpoint of that interval.

Part 2: Common Difference of Sequences

To find the common difference of the sequence – 5, – 2, 1, 4, 7,  …, you subtract any term from the term that follows it. For instance, – 2 - (– 5) = 3. Therefore, the common difference is 3.

Answer with Step-by-step explanation:

Jackie is selling smoothies at a school fair. She starts the day with $15 in her cash box to provide change to her customers.

Each smoothie costs $3.75, then cost of x smoothies is: $3.75x

Then, y=3.75x+15

When x=0 y=15

when x=4 y=3.75×4+15

             i.e.   y=30

The only graph which satisfies y=0 at x=0 and y=30 at x=4 is D.

Hence, the correct graph is:

D.

The number he should add on both sides of the equation to complete the square is 36.

The given equation is [tex]x^{2} - 12x = 16[/tex]

Thus, to make it a complete square, both sides of the equation must be a perfect square.

If we add number 36 on both sides of the equation, then the resulting equation is a perfect square.

⇒ [tex]x^{2} - 12x + 36= 16 + 36[/tex]

⇒ [tex](x-6)^{2} = 52[/tex]

∴  [tex](x-6)^{2} = (2\sqrt{13} )^{2}[/tex]

Thus, the given equation is a complete square from both sides.

Therefore, the number he should add on both sides of the equation to complete the square is 36.

Final answer:

Add 36 to both sides of the equation x²- 12x = 16 to complete the square, transforming it into a perfect square trinomial.

Explanation:

To complete the square for the equation x² - 12x = 16, you need to take half of the coefficient of x, which is -12, and square it. This process transforms the left-hand side into a perfect square trinomial. Therefore, you calculate (12/2)² which equals 36. This is the value that needs to be added to both sides to complete the square. The equation then becomes x² - 12x + 36 = 16 + 36, which simplifies to (x - 6)²= 52

Answer:

[tex]x=\frac{3}{2}[/tex]

Step-by-step explanation:

When we don't have any base with "log", we assume it to have base 10.

Using the property Log M + Log N = Log(M*N), we can write:

Log (2x-1) + Log 5 = 1

Log ((2x-1)(5)) = 1

We can turn this into exponential form using  [tex]Log_{a} b=x\\a^x=b[/tex]
