The tendency to perceive meaningful patterns in random sequences of outcomes often leads us to underestimate the extent to which outcomes result from CHANCE .

The word "chance" describes unpredictability or the unexpected in relation to things like events that happen without a clear reason why and without human intention.

The conclusion is that chance is the tendency of people to recognize different kinds of significant patterns in a random order or sequence in addition to evaluating any kind of outcome. Because chance can also result in an underestimating of a system's conclusion or result, it is crucial to consider it when conducting an investigation.

The answer to the expressions are

-5 - 9x - 8x + 2 = -3 -17x

6k - k = 5k

4 - 5(-8 + 2w) = 44 - 10w

8n + 2n - 3 = 10n -3

-5(7p - 3) - 2 = -35p + 13

To solve the question, we will simplify all of the expressions.

First, collect like terms

-5 + 2 - 9x - 8x  = -3 -17x

∴ -5 - 9x - 8x + 2 = -3 -17x

6k - k = 5k

First, clear the brackets

4 - 5(-8 + 2w) = 4 + 40 -10w  

= 44 - 10w

∴ 4 - 5(-8 + 2w) = 44 - 10w

8n + 2n - 3 = 10n -3

∴ 8n + 2n - 3 = 10n -3

First, clear the bracket

-5(7p - 3) - 2 = -35p + 15 -2

= -35p + 13

∴ -5(7p - 3) - 2 = -35p + 13

Hence, the answer to the expressions are

-5 - 9x - 8x + 2 = -3 -17x

6k - k = 5k

4 - 5(-8 + 2w) = 44 - 10w

8n + 2n - 3 = 10n -3

-5(7p - 3) - 2 = -35p + 13

A reasonable domain and range of the function is as follows:

A domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values (numbers) to a function and the domain of a graph comprises all the input numerical values which are shown on the x-axis.

By critically observing the given sequence, we can reasonably and logically deduce that it follows the following function rule:

f(x) = -5(2)^{x - 1}

When x = 1, we have:

f(x) = -5(2)^{1 - 1}

f(x) = -5(2)^{0}

f(x) = -5

When x = 2, we have:

f(x) = -5(2)^{2 - 1}

f(x) = -5(2)^{1}

f(x) = -10

When x = 3, we have:

f(x) = -5(2)^{3 - 1}

f(x) = -5(2)^{2}

f(x) = -5(4)

f(x) = -20

When x = 4, we have:

f(x) = -5(2)^{4 - 1}

f(x) = -5(2)^{3}

f(x) = -5(8)

f(x) = -40

When x = 5, we have:

f(x) = -5(2)^{5 - 1}

f(x) = -5(2)^{4}

f(x) = -5(16)

f(x) = -80

Therefore, a reasonable domain and range of the function is given by:

Domain is equal to {1, 2, 3, 4, 5, ....}

Range is equal to {-5, -10, -20, -40, -80, ....}

Amy's mistake was she took the angles as alternate interior angles, rather they form supplementary angles. The measure of both angles are  118 and 62.

The alternate interior angles theorem states that if a transversal connects two parallel lines, the alternate interior angles are identical in size. If we know the measure of the corresponding alternate interior angle, we may use this theorem to determine the measure of the alternate interior angle.

As per the given question,

both angles are not alternate interior angles,

rather both of the angles are supplementary angles.

This means that both form the sum of 180

⇒ 3n - 47 + n + 7 = 180

⇒ 4n - 40 = 180

⇒ 4n = 220

⇒ n = 55

∴ The measure of both angles will be 3n - 47 = 118 and n + 7 = 62

Step-by-step explanation:

10/10-1/10=9/10=Colin and Sarah share

2x+7x=9x=Colin and Sarah share

9x=9/10

x=1/10

Colin=2x=2/10=1/5

The ratio shows how many times one value is contained in another value.

The proportion that Caroline gets is 1/10.

The proportion that Colin gets is 2/10.

The proportion that Sarah gets is 7/10.

So,

The proportion that Colin gets is 7/10 of the money.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

Let the total amount of money be 1.

Caroline:

Share = 1/10 of the money

Remaining money:

= 1 - 1/10

= 9/10

Colin and Sarah:

Share = 2:7

Colin share = 2/9 x 9/10 = 2/10

Sarah share = 7/9 x 9/10 = 7/10

The proportion that Caroline gets is 1/10.

The proportion that Colin gets is 2/10.

The proportion that Sarah gets is 7/10.

Thus,

The proportion that Colin gets is 7/10 of the money.

Step-by-step explanation:

Answer:

Slope would equal 3.

slope= (y2-y1)/(x2-x1)

Plug in you get (8-2)/8-6)

Simplify (6)/(2)=3

Step-by-step explanation:

We will get that the angle theta is:

θ = β/2

Remember that the sum of the interior angles of any triangle must be equal to 180°.

Now, looking at the triangle in the left, we can see that the top angle is equal to:

180 - 2α

The right angle is equal to:

180 - 2β

And the left angle is α

Then we can write:

α + (180 - 2α) + (180 - 2β) = 180

-α - 2β = -180

α = 180 - 2β

Now we can go to the other triangle, where theta is, and write:

α + β + 2θ = 180

Replacing what we found above, we get:

180 - 2β + β + 2θ = 180

-β + 2θ = 0

θ = β/2

That is the best simplification we can get with the given diagram.

The GCF is 13.

Factor the 13 out; it's like Distributive Property in reverse.

13 (2 + 3)

13 (5)

65

26+39= 65, so we obtain the same answer as just adding, by using GCF and Distributive Property.

Answer:

  13(2 +3)

Step-by-step explanation:

26 = 2·13

39 = 3·13

The greatest common factor is 13, so the sum can be written ...

  26 +39 = 13(2 +3)

Additional comment

Of course, the value of the sum is ...

  13(2+3) = 13(5) = 65

Alternatively, the sum can be evaluated as ...

  26 +39 = 26 -1 +1 +39 = (26 -1) +(1 +39) = 25 +40 = 65

The amount the firm needs to deposit in the account now is 9,640.11. Given that the company has purchased a life truck with a useful life of 5 years, the maintenance costs for the truck during the first year are 2,000.

Also, maintenance costs are expected to increase at a rate of 300 per year over the remaining life, which is for four years. Assume that the maintenance costs occur at the end of each year.

The future maintenance costs for the truck can be calculated as shown below:

Year 1:\($2,000Year 2: $2,300Year 3: $2,600Year 4: $2,900Year 5: $3,200\)The maintenance account that earns 10% interest per year has to be set up, and all future maintenance expenses will be paid out of this account. The future value of the maintenance costs, i.e., the amount that the firm needs to deposit now to earn 10% interest and pay the maintenance costs over the next four years is given by:

\(PV = [C/(1 + i)] + [C/(1 + i)²] + [C/(1 + i)³] + [C/(1 + i)⁴] + [(C + FV)/(1 + i)⁵]\),where PV is the present value of the future maintenance costs, C is the annual maintenance cost, i is the interest rate per year, FV is the future value of the maintenance costs at the end of year 5, which is $3,200, and 5 is the total number of years, which is

5.Substituting the given values in the above equation:

\(PV = [2,000/(1 + 0.1)] + [2,300/(1 + 0.1)²] + [2,600/(1 + 0.1)³] + [2,900/(1 + 0.1)⁴] + [(3,200 + 3,200)/(1 + 0.1)⁵] = 9,640.11\)Therefore, the firm needs to deposit 9,640.11 in the account now. Hence, option (A) is the correct answer.

f(2) - g(-2) = 3, and the correct answer is option c) 3.

To find the value of f(2) - g(-2), we first need to evaluate the expression f(2) and g(-2) separately and then subtract the two results.

Given that f(x) = 3x - 3, we can substitute x = 2 into the equation:

f(2) = 3(2) - 3

f(2) = 6 - 3

f(2) = 3

Similarly, given g(x) = -x² + 4, we can substitute x = -2 into the equation:

g(-2) = -(-2)² + 4

g(-2) = -(4) + 4

g(-2) = -4 + 4

g(-2) = 0

Now, we can subtract g(-2) from f(2):

f(2) - g(-2) = 3 - 0

f(2) - g(-2) = 3

Therefore, f(2) - g(-2) = 3, and the correct answer is option c) 3.

Step-by-step explanation:

After 2 years, the value of the boat is, $19,200

After 8 years, the value of the boat is, $5,033.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The graph represents the value $y of a boat after x years.

Here, A graph titled, value of a boat. The horizontal axis is labeled year. The vertical axis is labeled value (thousands of dollars).

And, The graph shows a curve that passes through the points, ordered pair 0 comma 30, ordered pair 1 comma 24, ordered pair 3 comma 15.36, and ordered pair 5 comma 10.

Now, The equation of graph is,

⇒ y = k (a)ˣ

Since, The graph is passes through the point (0, 30),

⇒ 30 = k × 1

⇒ k = 30

Hence,  Calculate the ratio between y values:

⇒ 24/30

⇒ 4/5

So, The equation is,

⇒ y = k (a)ˣ

⇒ y = 30 (4/5)ˣ

Hence, After 2 years, the value of the boat is,

⇒ y = 30 (4/5)²

⇒ y = 30 × 16/25

⇒ y = $19.2

⇒ y = $19,200

And, After 8 years, the value of the boat is,

⇒ y = = 30 (4/5)⁸

⇒ y = 5.033

⇒ y = $5,033

The correct answer of the operation is option B: 4x^2 - 9.

To perform the operation (2x-3)(2x+3), we can use the FOIL method, which stands for First, Outer, Inner, Last. Let's go through the steps:

First: Multiply the first terms of each binomial.

(2x)(2x) = 4x^2

Outer: Multiply the outer terms of each binomial.

(2x)(3) = 6x

Inner: Multiply the inner terms of each binomial.

(-3)(2x) = -6x

Last: Multiply the last terms of each binomial.

(-3)(3) = -9

A binomial is a two-term algebraic expression that contains variable, coefficient, exponents and constant, a binomial is an expression that has two unlike terms connected through an addition or subtraction operator in between.  

Now, let's combine the like terms:

4x^2 + 6x - 6x - 9

Notice that the terms 6x and -6x cancel each other out.

Simplifying further, we have:

4x^2 - 9
