The expression written in another way is -9 + m

Expressions are mathematical statements that are represented by variables, coefficients and constants

The expression is given as:

m - 9

By the subtraction property of an equation, we have

a - b = -b + a

x - y = -y + x

Using the above equations as a guide, we have

m - 9 = -9 + m

Hence, the expression written in another way is -9 + m

Step-by-step explanation:

The expression, in the end, is 10 x 3 = 30

i.e

Length = 10

Width = 3

The number of tiles = 10 x 3 = 30

We have,

We see that,

The number of tiles:

18, 24, 30,

This is an arithmetic sequence.

So,

The next term:

= 30 + 6

= 36

Now,

The length is a sequence in ascending order of the factor of the arithmetic sequence.

So,

30 is a factor of 2, 3, 5, 6, and 10.

This means,

The expression, in the end, is 10 x 3 = 30

So,

Length = 10

Width = 3

The number of tiles = 10 x 3 = 30

Answer:

\(2x^{2} +13x-45\)

Step-by-step explanation:

By using FOIL method.

Answer:

Below!

Step-by-step explanation:

Let the irrational number be known as "x".

\(\implies -\sqrt{41} \times x = 1\)

Divide both sides by -√41.

\(\implies \dfrac{(-\sqrt{41} \times x)}{-\sqrt{41} } = \dfrac{1}{\sqrt{-41} }\)

\(\implies x = \dfrac{1}{-\sqrt{41} }\)

Take the "-" to the numerator:

\(\implies x = \dfrac{-1}{\sqrt{41} }\)

Use parenthesis to isolate the "-"

\(\implies x = -\huge\text{(}\dfrac{1}{\sqrt{41} } \huge\text{)}\)

Note: 1 can also be written as √1. (√1 = √1 × √1 = 1)

\(\implies {x = -\huge\text{(}\dfrac{\sqrt{1}}{\sqrt{41} }\huge\text{)}}\)

Combine the roots in the equation:

\(\implies {x = -\huge\text{(}\sqrt{\dfrac{1}{41} }} \huge\text{)}}\)

Remove the parenthesis:

\(\implies {x = -\sqrt{\dfrac{1}{41} }}\)

Thus, Option C is correct.

To determine the range of the number of RVs that need to be sold each month for the company to make a profit, we need to consider the profit function and find the values of x that result in a positive profit.

The profit function is given by P(x) = -50x + 20,000x - 1,500,000.

To make a profit, the value of P(x) must be greater than zero (P(x) > 0). We can set up the inequality:

-50x + 20,000x - 1,500,000 > 0.

Combining like terms, we have:

19,950x - 1,500,000 > 0.

Now, let's solve this inequality for x:

19,950x > 1,500,000.

Dividing both sides by 19,950, we get:

x > 1,500,000 / 19,950.

Simplifying the right side, we have:

x > 75.

The range of the number of RVs that need to be sold each month for the company to make a profit is x > 75.

Among the given answer choices, the correct option that represents this range is "0 100 200 none of the answer choices".

The arc that is covered by the red - shaded area in the circle has a degree measure of 165 degrees. This is out of the total circle angle measure of 360 degrees.

This therefore means that the probability that a randomly selected point within the circle would fall in the red- shaded area can be found to be :

= Angle measure of red - shaped area / Total area x  100 %

1/36

Step-by-step explanation:

For each roll, the probability that the die rolls a 3 is 1/6

So, for it to happen on both dice is 1/6 * 1/6 = 1/36

The probability that an event will repeat its self for independent events is given by the square of the probability of the event occurring

Reason:

Number of faces in a fair die = 6 faces

Numbers on the faces of a fair die = 1, 2, 3, 4, 5, and 6

Number of 3s on the face of a fair die = 1

Probability that a roll of a fair die gives the face of 3, P(3) = \(\dfrac{1}{6}\)

The probability that two rolls of a fair die are both, is given as follows;

P(Both 3) = P(3 and 3) = P(3 ∩ 3)

The and condition of two independent probabilities is the product of the two probabilities, therefore;

P(3 ∩ 3) = \(\dfrac{1}{6} \times \dfrac{1}{6} = \dfrac{1}{36}\)

The probability that both rolls are 3s P(Both 3s) = \(\underline{\dfrac{1}{36}}\)

To complete this problem is a straightforward answer:

First, you add 14.75 + 1.03 which equals $15.78 then, you'll want to add 2.50 to 15.78 and there you have your answer!!

The binomial factors of x³- 4x²+x+6​ are (x+2), (x+3), and (x-1).

Using the splitting and grouping the terms:

x³ + 4x² + x - 6

= x³ + 2x² + 2x² + x - 6  [Splitting 4x² = 2x² + 2x²]

= (x³ + 2x²) + (2x² + x - 6)

= x² (x + 2) + (2x² + 4x - 3x - 6)

= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]

= x² (x + 2) + (x + 2) (2x - 3)

= (x + 2) ( x² + 2x - 3)

= (x + 2) ( x² + 3x - x - 3)

= (x + 2) [x (x + 3) - 1 (x + 3)]

= (x + 2) (x + 3) (x - 1)

Hence, the binomial factors are (x + 2), (x + 3) and (x - 1)

The probability that the next person will purchase one or more costumes as a decimal to the nearest hundredth is 0.443

Out of 217 visitors who came to Nayeli's website, none of them purchased a costume. Therefore, the number of visitors who may purchase a costume is 217 less than the total number of visitors:

Total visitors - No. of visitors who didn't purchase a costume = 217

Total visitors - 217 = No. of visitors who may purchase a costume

Total visitors = 113 + 217+36 = 336

Out of the remaining visitors, 113 purchased exactly one costume, and 36 purchased more than one costume. Therefore, the number of visitors who purchased one or more costumes is:

No. of visitors who purchased one or more costumes = 113 + 36 = 149

Therefore, the probability that the next person will purchase one or more costumes can be expressed as:

Probability = No. of visitors who purchased one or more costumes / Total visitors

Probability = 149 /336 = 0.443

The probability that the next person will purchase one or more costumes as a decimal to the nearest hundredth is 0.443

Answer:

The equations are:

\(4H + 3P = 13.75\)

\(2H + 5P = 11.25\)

\(Hotdog = 2.50\)

\(Pretzel = 1.25\)

Step-by-step explanation:

Let:

\(H = hot\ dog\)

\(P =Pretzel\)

For Tina:

\(4H + 3P = 13.75\)

For Doug:

\(2H + 5P = 11.25\)

Solving for the price of both items:

We have:

\(4H + 3P = 13.75\) --- (1)

\(2H + 5P = 11.25\) --- (2)

Multiply (2) by 2

2 * (\(2H + 5P = 11.25\))

-------------------

\(4H + 10P = 22.50\) --- (3)

Subtract (3) from (1)

\(4H + 3P = 13.75\)

\(4H + 10P = 22.50\)

----------------------

\(4H - 4H + 3P - 10P = 13.75 - 22.50\)

\(3P - 10P = 13.75 - 22.50\)

\(-7P = -8.75\)

Solve for P

\(P = \frac{-8.75}{-7}\)

\(P = 1.25\)

Substitute 1.25 for P in (2)

\(2H + 5P = 11.25\)

\(2H + 5 * 1.25 = 11.25\)

\(2H + 6.25 = 11.25\)

Collect Like Terms

\(2H = 11.25-6.25\)

\(2H = 5\)

Where n is the position of the number in the sequence.

So, for example:

The equivalent form of the function showing the remainder as a fraction is: h(x) = (x - 6) + 4 / (x - 4)

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

The given function is:

h(x) = (x^2 - 2x - 4) / (x - 4)

To rewrite this function in an equivalent form showing the remainder as a fraction, we can use polynomial division.

Let's divide x^2 - 2x - 4 by x - 4:

           x - 6

   --------------------

x - 4 | x^2 - 2x - 4

      - (x^2 - 4x)

      -------------

            2x - 4

            - (2x - 8)

            ---------

                   4

Therefore, we can write:

h(x) = (x^2 - 2x - 4) / (x - 4) = (x - 6) + 4 / (x - 4)

Therefore,  the equivalent form of the function showing the remainder as a fraction is: h(x) = (x - 6) + 4 / (x - 4)

The coefficient of variation for A is 20.37% and for B is 15.98%.

What is coefficient of variation?

In statistics, the relative standard deviation (RSD), commonly referred to as the coefficient of variation formula (CV), is a standardized way to assess how widely spaced out a probability distribution or frequency distribution is. Lower values of the coefficient of variation indicate that the data is highly stable and less variable.

We know that formula for coefficient of variation is

CV = Standard Deviation / Mean

A. $31,100, $25,800, $36,300, $30,200, $30,000, $19,800, $22,300, $22,600, $34,900, $21,700, $36,900, $30,800, $31,700, $37,100

Mean = 411200 / 14

Mean = $29371.42

Similarly,

Standard Deviation = $5984.52

So,

CV = 5984.52 / 29371.42 * 100

CV = 20.37%

B. 3.18, 4.24, 4.27, 4.38, 3.87, 4.75, 3.43, 3.35, 4.16, 4.81, 2.98

Mean = 43.42 / 11

Mean = $3.94

Similarly,

Standard Deviation = $0.63

So,

CV = 0.63 / 3.94 * 100

CV = 15.98%

Hence, the coefficient of variation for A is 20.37% and for B is 15.98%.
